Temporary Strainer Factory

A temporary Strainer is a perforated braided mesh device consisting mainly of components such as a handle, filter element, stainless steel screen layer, seals, and fasteners to capture particles in the pipe.

Tapered filters can capture particles as small as 0.001 inch or 25 microns in diameter. In addition, the pressure drop of the cone filter is so small that you can remove it. Alternatively, we can weld the sieve cone to the entire circumference of the flange ring. This provides strength and prevents unnecessary bypasses.

The temporary filter is installed at the front end of the matching valves in the water inlet pipe. When the medium in the pipeline first enters the filter, the medium enters the connected valve through the filter screen, and the impurities are left in the cylinder body, so that all kinds of valves will not fail due to the impurities stuck in.

When using temporary filters, the filter element should be replaced regularly, which can ensure high quality compressed air into the system, so as to protect the adsorption medium of the adsorption dryer and reduce user costs.

This design provides inexpensive protection for expensive meters, valves, pumps, and other mechanical equipment from oxide skin welding residue, dirt, and other foreign objects during startup.

The purpose of the temporary strainer is to filter debris and to protect the fluid and gas handling equipment during commissioning and start-up. For better filtering, an extended signal arm is provided so that the position of the temporary filter can be clearly seen.

The temporary strainer is easily fitted between flanges without any modifications to the surrounding piping or the need for special short fittings. With their rugged design, these filters can operate at high pressure differentials.

When filtering debris, water flows from the inside out to collect the debris in the cage for easy removal. Filters for counter current can be manufactured if desired.

In order to filter debris more finely, BS970-compliant stainless steel braided wire mesh is spot-welded to the inner surface of the filter to ensure they are fully supported. Plugins as small as 300 mesh (0.002 aperture) are also available.

This design also protects expensive meters, valves, pumps, and other mechanical equipment from oxidation residue, dirt, etc., during startup.

Start up strainer is also a Temporary Strainer used to remove debris from the fluid in the ductwork, usually during startup. Designed to be mounted with the cone pointing upstream or downstream, depending on which direction there is enough room for the length of the cone or basket.

Boot filter if there is no length issue, flow depends on customer preference. If the filter is pointed upstream, debris tends to collect at the paddle ring of the filter, making it necessary to remove any loose debris from the pipe. If pointed downstream, debris will accumulate inside and at the end of the filter; So it’s easier to clean.

Startup filters are designed for temporary use, so the total opening area required should be based on the allowable pressure drop of the filter, and the amount of debris captured is expected after startup. These filters are a low cost alternative to monoculars and other permanent filters.

Bucket type strainer is also Temporary Strainer and are made of the highest quality stainless steel perforated plates and are fully welded to ensure zero leakage. The desired degree of filtration is provided by welding a suitable grade of stainless steel mesh to the barrel. It can be installed vertically or horizontally, and it can operate under extreme pressures and temperatures without damage.

The filter is in the form of a basket with a handle, so all particles caught and retained by the filter can be easily removed for disposal. The particles are collected in the basket, then the production line is temporarily shut down and the basket is removed for cleaning or replacement. Advanced dynamic flow path and large filter area elements ensure low pressure drop and reduce maintenance cycle. These filters reduce cleaning downtime due to their bolt-cover construction and easy-to-remove filters.

The bucket type strainer is lightweight and easy to install because of its small size, but it can have a long service life because it has enough components and case strength.

Conical filter is also a Temporary Strainer, a conical filter made of a thick gauge perforated plate with a drill hole in the offset center to capture debris in the pipe during startup. It can be made of many different types of metals or alloys to any length.

Our material types are very versatile and can meet customers’ different filter applications. They can be customized with or without stainless steel wire mesh to filter out even the smallest particles.

Tapered filters are usually temporary pipe filters. These temporary pipe filters are a cost-effective alternative to in-line Y or basket filters and a cost-effective solution for starting applications.

Tapered filters are used for steam, water, oil or gas services and are mounted between two flanges to protect downstream equipment. They are used either on a temporary basis or in situations where cost is very important. Install a tapered filter with the tip facing the direction of flow. The tapered filter is designed to collect debris around the outer edge of the cone, as this is a direction of higher mechanical strength.

Temporary Strainer is not specifically designed to filter debris and also protects fluid and gas handling equipment during commissioning and startup. Filters are easily installed between flanges and do not require any modifications.

Temporary filters are made of various non-steel materials, so they are very durable and have a wide range of pressure levels.

The temporary filter is not only easy to use, but also works at high pressure differences, and the signal arm is extended for easy identification. Fluid flows from inside to outside, gathering debris in the cage for easy removal. If desired, the filter can be used for counter flow or to suit the customer’s specifications.

It has the advantages of good air permeability, high water holding capacity and recycling after cleaning. Because of their durability, tapered filters are commonly used for high-speed fluid filtration in the pharmaceutical, chemical, pesticide and food industries.

Temporary pipeline strainers can trap particles as small as 0.001 inch or 25 microns in diameter. In addition, the pressure drop of the cone filter is so small that you can remove it.

We can weld the sieve cone to the entire circumference of the flange ring. This provides strength and prevents unnecessary bypasses. By installing filters, chemical operations can be significantly improved, and longer equipment life is guaranteed.

Temporary pipeline strainers make it easier to clean the filter unit while the system is still running, thus reducing maintenance downtime. The filter’s large surface provides long service life and minimal pressure drop, and the flow from inside to outside provides maximum strength.

Installing temporary pipe filters in front of expensive process equipment prevents scale, dirt, or byproducts from causing damage, thereby avoiding costly downtime. In addition, pipe filters prevent flow meter and nozzle clogging.

Basket filters allow for greater open area and higher flow rates while taking up less pipe length. Tapered filters are generally better suited for high-pressure applications due to their tapered design.

Temporary Filters can be used for liquid or gas applications, but the installation and lining on the filter screen depends on the nature of the fluid. As a rule of thumb, the first point of contact for the fluid must be the mesh and not the perforation.

Temporary Strainer In gas applications, the mesh is lined on the outside of the perforation and the cone is positioned so that the airflow hits the sharp side and flows inward from the outflow. As a result, all unwanted particles are deposited on one side of the outer surface cone. During maintenance, the temporary filter is removed from the pipe and an air gun is used to spray a stream of air from inside out. As a result, all the unwanted particles trapped on the outside of the cone are blown away.

Therefore, in order to be cleaned effectively during overhaul, in the gas line, the temporary filter must have mesh on the outside of the perforation, and the flow of gas must be from the outside to the inside.

Temporary Strainer is also suitable for a variety of steam, liquid, gas and oil, power, pulp and paper, process equipment, chemical, metal and mining, and water and waste applications.

1. Use location

Temporary Strainer Materials may get stuck in the pipes during construction. These materials may be welding slag, welding rods, wood chips, cigarettes, rocks, etc. If these chips get in, a lot of equipment will be damaged. After startup, remove startup screen.

     2. Materials

The structural material of the temporary strainer shall be compatible with the fluid. The most commonly used structural materials are stainless steel 304, 306 and so on.

3. Size standard

The size of the temporary strainer is specified by the manufacturer and the main disk of the tapered filter is installed between the rated flanges conforming to the main specifications.

4. Design requirements

If the filter cannot withstand high temperature or differential pressure, it may spread out and cause equipment damage. The expected pressure drop of the filter should not cause the downstream working pressure to fall below the minimum pressure required for the line, such as the cavitation allowance of the pump.

5. Cone direction upstream or downstream

The installation of the cone filter can be done in one of two different ways, with the cone facing upstream or the cone facing downstream. When the cone is downstream, debris accumulates inside the cone near the tip, and the cone may tear due to heavy stress on the tip.

The advantage of the tapered downstream side is that it is easier to remove debris. However, the mechanical strength of the cone should be guaranteed. When the cone is upstream, debris accumulates on one side of the filter. The advantage is that any blockage in the filter will start outside and work its way in.

Bucket Type Strainer, also a Temporary Strainer, is the perfect choice for situations requiring fast flow and high pressure. It is easy to maintain and clean. Because of easy access to the filter element, it is easy to replace, clean and repair.

The double basket filter is also very convenient because it allows continuous operation while cleaning or servicing the filter, so it does not interrupt the output of the filter, so it is very easy to use and handle.

Selecting the appropriate basket filter according to the requirements can not only protect the downstream equipment, but also reduce the operation and maintenance costs of the machine, which can save a lot of money.

And it’s important for businesses to use filters. For industrial use, filters are used to extract larger unwanted particles, such as sand, dirt, organic materials and chemical damage, from pipes or industrial component streams, while filters are used to remove smaller solids or even invisible chemical components.

Start Up Strainer is the Temporary Strainer that provides 100% or more open area in the cone or basket before adding wire mesh. The catalog sizes show the lengths of the 100%, 150%, 200%, and 300% open areas for each size filter in the cone and basket configurations. These lengths are based on perforated metal, with 1/8 “diameter holes in the 3/16” staggered center, and a plane with 42% open area. When using a flat filter of this material, the opening area is 42%.

Flat filters are recommended only in applications where there is insufficient space for tapered or basket filters. To provide 100% or more open areas, the perforated material must be designed to be tapered or basket-shaped and lengthened to allow for the addition of wire mesh (if any).

The start up strainer has a larger volume and greater surface area than a conical filter of the same length, providing a comparable operating pressure drop. Their required length is shorter, allowing the use of basket filters on shorter pipe runs and with limited pipe availability.

1. Petrochemical process

In temporary strainer, basket filters are useful in the petrochemical process because they are able to filter unwanted solid particles from the fuel lines and distribution lines, and some filters are used to further purify the material, usually below the feed line.

2. Pharmaceutical industry

The pharmaceutical industry also uses industrial basket filters in all its operations. Both prescription drugs are designed to make individuals feel better. This ensures that goods must meet the best hygiene standards throughout the manufacturing process. The use of sanitary 3A certified wire basket filters in the manufacturing process will ensure that the goods are fit for human use.

3. Paint manufacturing

Another industry that relies heavily on basket filters involves paint manufacturing. It is important that the final product is free of all unwanted solids and that the paint is smooth and easy to apply. Filtration systems are often used in some cases to ensure that the final product is consistent and free of any clumps or particles that would affect the quality of the paint applied and after painting.

4. Other industries

Basket filters are used for many of these applications, such as the power industry, environmental industry, food industry, and chemical industry.

1. Material type

Temporary strainer mainly adopts stainless steel 302, 304, 316, 316L, Monel alloy, galvanized materials and so on. Fabricate temporary cone, basket and plate filters using thick gauge perforated plates, woven wire mesh and lithographic filters. Our material types are very versatile and can meet customers’ different filter applications.

2. Size

Conical strainer can be customized with or without stainless steel mesh to filter out even the smallest particles. We offer a wide range of mesh sizes ranging from 8 to 400 mesh. Available in sizes from 1 “- 36” and grades from 150 to 2500. They are manufactured to fit flanges RF and RTJ in accordance with ANSI B16.5.

Depending on the direction of flow, wire mesh can be added to the inside or outside of a basket or conical temporary filter. Temporary tapered or basket filters can be made of carbon steel or any stainless steel grading to any length and diameter.

3. Open up areas

Open area is usually 100% across all inventory screen sizes. Longer lengths (larger open area) or shorter lengths (less open area) are available on request.

Bucket Type Strainer is made of stainless steel mesh, and the Temporary Strainer can detect specific particles between 50 and 70 microns on average. Most people can’t see anything smaller than 325 mesh or 44 microns. Since 200 mesh equals 74 microns, the general rule is that if the screening device is thicker than 200 mesh, it is a person, and if it is thinner than 200 mesh, it is a filter.

The free opening area is the ratio of the opening area through the filter basket to the cross-sectional area of the pipe. A common term used in filter design is the “open area ratio” (OAR), which is equal to the total area of the open basket divided by the internal cross-sectional area of the intake pipe. It is a measure of relative debris capacity and is usually 1 to 4 times the area of the inlet pipe.

Whenever you purchase an industrial basket filter for installation in a ductwork system, ensure that system parameters such as operating pressure, temperature, and flow rate must conform to the filter’s standard specifications.

Temporary strainer, as the name suggests, is designed for temporary use. It’s typically used during the initial commissioning phase of a piping system. It’s also used during maintenance activities. Temporary strainers are often made from materials like stainless steel or perforated metal. They are placed in the pipeline. Their purpose is to catch debris or foreign particles. This occurs during system startup or maintenance.

On the other hand, a permanent strainer is intended for long-term use within a piping system. Unlike temporary strainers, permanent strainers are usually fabricated from more robust materials. These materials include stainless steel, bronze, or brass. They are designed to withstand the flow of fluids over an extended period.

They are installed in the pipeline. Their purpose is to protect downstream equipment. This equipment includes pumps, valves, and meters. Protection is against damage caused by debris or particulate matter.

Installing a temporary cone involves several steps. First, select the appropriate strainer for your application based on material and mesh size. Shut down the pipeline, relieve pressure, and ensure cleanliness. Identify the installation location near sensitive equipment.

Insert the strainer with the pointed end facing upstream for cone-shaped basket strainers or the open end for basket strainers. Secure it in place if needed with clamps. Re-pressurize the pipeline and monitor flow and pressure to ensure efficient debris capture without significant pressure drop.

Once maintenance is complete, shut down the pipeline again, remove the strainer, and inspect it for debris buildup. Clean if necessary and ensure no debris remains in the pipeline or downstream equipment. Always adhere to manufacturer instructions for proper installation and operation.

Temporary strainer is typically used in piping systems. Its purpose is to protect sensitive downstream equipment. This equipment includes pumps, valves, and meters. Protection is against damage caused by debris or foreign particles. It’s used during initial commissioning or maintenance activities.

These strainers are installed temporarily. Installation occurs during construction, commissioning, or maintenance phases. They are removed once the system is operational. They can also be removed after the initial debris has been flushed out. They serve as a cost-effective solution. The purpose is to prevent damage to critical components. This prevention ensures smooth operation and longevity of the equipment.

When it comes to choosing a strainer for pump suction, two common options are basket strainers and Y-strainers. Basket strainers feature a perforated basket or screen. This basket or screen captures larger particles or debris. They are suitable for high-flow applications. Periodic maintenance is needed.

On the other hand, Y-strainers, named for their shape, utilize a cylindrical screen or mesh to intercept debris, ideal for space-constrained setups where temporary flow interruption for maintenance is acceptable.

Selection criteria include particle size, flow rate, pressure drop, ease of maintenance, and compatibility with the pump and fluid. Regular inspection and cleaning are crucial. The purpose is to maintain optimal pump performance.

It also prevents damage to downstream equipment. Ultimately, the choice between basket and Y-strainers depends on factors like system requirements, space constraints, and maintenance considerations. This ensures efficient and reliable pump operation.

Temporary strainers are installed in a pipeline. They catch debris. This happens during commissioning. This also happens during maintenance activities. Temporary strainer has an arrow. The arrow indicates the flow direction. It is usually found on the strainer body or housing. The arrow points. It shows the direction. Fluid should pass through.

This is how to catch debris and contaminants effectively. It’s crucial. Ensure the strainer’s correct orientation. Follow the flow direction. This optimizes performance.

Mesh size matters. It maintains pump performance. It prevents damage. This is crucial for a pump suction strainer. Mesh size varies. It ranges from 20 to 100 mesh. Selection depends on factors. These factors include pump type, size, fluid characteristics, and filtration needs.

Coarser meshes (20-40 mesh) are suitable for larger debris, ensuring adequate flow while capturing particles. Finer meshes (60-100 mesh) offer finer filtration for smaller particles but require careful consideration to prevent clogging and maintain flow rates.

Strainers with mesh sizes too fine risk restricting flow, leading to cavitation or pressure drop issues, while those too coarse may allow harmful particles to pass through. Consulting with pump manufacturers or fluid handling specialists can ensure the mesh size aligns with the specific requirements of the application.

Ultimately, the mesh size chosen should balance effective filtration with optimal pump performance, ensuring efficient operation and minimizing maintenance needs.
