Strainers

Strainer Manufacturer in USA 

SVR Global designs strainers to clean solids, scales, and debris from pipes containing liquids or gases before they get to pumps, valves, meters, and other equipment downstream.Each strainer has been engineered to endure constant pressure, temperature changes, and harsh mediums in heavy-duty industrial pipelines in the United States.

Strainer Types We Manufacture :

Simplex Basket Strainer-
A single chamber strainer with a removable basket screen that traps debris from the flow, requiring a brief flow stop for cleaning.

Y Strainer-
A compact, angled body strainer with an internal screen that filters debris with minimal pressure drop, suited for space limited installations.

Working Principle of a Strainer:

• The strainer is installed directly in the pipeline, upstream of pumps, valves, meters, or other process equipment.

• Fluid enters the strainer body and passes through a perforated or wire mesh screen fitted inside the housing.

• Solid particles, scale, rust, weld slag, or other debris carried in the flow are stopped at the screen surface.

• The filtered fluid continues through the outlet into the rest of the system.

• Trapped particles build up on the screen over time and begin to restrict flow, which shows up as a rise in pressure drop across the strainer.

• The screen or basket is then removed through an access cover, cleaned or replaced, and reinstalled.

• In a duplex strainer, a diverter valve routes flow to a second chamber during this process, so the line does not need to be shut down for cleaning.

• Mesh or perforation size is selected based on the smallest particle size that needs to be stopped and the flow rate the line is designed to carry.

Manufacturing Standards and Testing:

• Each strainer is checked for dimensional accuracy, weld integrity, and pressure retention before dispatch.

• Products are manufactured to align with ASME, ASTM, and API reference standards depending on the application and end use pipeline class.

Industries We Serve:

• Oil & Gas Processing - Strainers protect pipelines and process equipment from sand, scale, and debris across upstream and downstream operations.

• Petrochemical plants – These are utilized in feed stock and process lines to avoid any particulates from entering the pump, valve, and reactor.

• Power generation – These filters are used in the cooling water and steam line in order to ensure that no particulates enter the turbine, condenser, and boiler.

• Marine and shipbuilding – In the seawater and fuel line, these filters remove marine growth, silt, and particulates.

• Chemical processing – Removal of any solids from the corrosive or reactive fluids.

• Water and Wastewater Treatment - Removes suspended solids and debris from intake and treatment lines.

• Mining and Mineral Processing - Filters slurry lines and process water carrying abrasive particulates.

• Steel and Metal Fabrication Plants - Used in cooling and processing water lines to stop scale and metal fines.

• Refineries and Offshore Platforms - Guards high pressure lines against sand, scale, and pipeline debris.

• Desalination Plants - Installed in intake lines to remove sediment and marine debris before filtration stages.

Standards & Certifications:

• ASME B16.34 - Pressure temperature ratings for valves and strainer bodies

• ASME B16.5 / B16.47 - Flange dimensions and end connection standards

• ASTM A216 / A351 / A995 - Material specifications for cast steel and stainless steel components

• API 598 - Inspection and testing procedures

• MSS SP-6 / SP-25 - Face to face dimensions and marking standards

Custom Strainer Fabrication:

SVR Global builds strainers to custom face to face dimensions, mesh sizes, perforation patterns, and pressure ratings for pipelines that fall outside standard catalog sizing.
