Industrial strainers

We offer cast and constructed strainers for sale. Although manufactured strainers can be completely modified to fit process or site requirements, cast strainers have conventional dimensions. Every one of our strainers is made and tested in compliance with ASME specifications. Cast iron, ductile iron, carbon steel, low-temperature steel, stainless steel, duplex stainless steel, alloy steel, and other body materials can all be used to build strainers.

The strainer’s aesthetics are given a great deal of attention. With top paint brands like JOTUN, INTERNATIONAL, HEMPEL, and others, any external painting requirement is met. Strainers intended for corrosive fluid can also be inside coated with rubber lined or Belzona in addition to external coating. To prevent damage during shipping, our strainers are placed in hardwood crates, secured with straps, and their flanges are taped.
In addition to Y-strainers, Basket strainers, Tee strainers, Duplex strainers, and Temporary strainers, we provide the entire line of metal strainers. At 1.5 times the design pressure, all strainers with housings are hydro tested. All weld joints in the case of welded strainers are subject to 100% NDE. Any step of manufacturing or testing is open to third party inspection organisations sponsored by clients. All of our strainers can be purchased with complete material certificates in accordance with EN 10204/3.1. In unique circumstances, we can additionally offer strainers certified to EN 3.2 material. Infinity Industrial Supplies also fabricates and provides strainers with U-stamp or PED marking.

Specification Requirements

The following information is fundamental to ensure the correct specification of strainer equipment for its intended purpose.

Filtration Size

The common purpose of a strainer is to remove debris from a process stream. Strainer elements are available with a range of filtration sizes from as large as 10mm perforations down to 25 micron (0.025mm) fine woven wire mesh. Correct selection of the filtration size is very important and should relate to the maximum particle size that downstream equipment (eg. pumps) is capable of handling.If the filtration size is too large then escaping debris could seriously affect the performance of downstream equipment. A filtration size that is too small could result in increased maintenance to clean the strainer and/or increased pressure drop, which can be detrimental to the downstream process.
