AWS – Technical profile of an industrial strainer, filter and pipeline protection equipment manufacturer

AWS is associated with industrial filtration and pipeline protection equipment used upstream of pumps, control valves, meters, heat exchangers and sensitive process equipment. The product range typically includes strainers, filters and accessories for protecting piping systems from solids, welding debris, rust and process contamination.

The main product categories include:

• Y-type strainers,
• basket strainers,
• duplex strainers,
• temporary strainers,
• filter elements,
• blowdown and drain accessories,
• special fabricated strainers.

Y strainers are compact and suitable for general service in steam, water, air, oil and utility systems. They are installed in-line and require access for screen removal and cleaning. Basket strainers provide larger dirt-holding capacity and are useful where solids loading is higher.

Duplex strainers allow continuous operation while one basket is cleaned and the other remains in service. They are used in cooling water, fuel oil, lubrication, seawater and process systems where shutdown for filter cleaning is not acceptable.

Temporary strainers are commonly used during commissioning to capture welding slag, pipe scale and construction debris. They should not remain permanently installed unless specifically designed for that duty.

Technical selection requires:

• DN / NPS and pressure rating,
• connection type,
• body material,
• screen material,
• mesh or perforation,
• open area ratio,
• clean and dirty pressure drop,
• drain / vent connection,
• cleaning access,
• compatibility with steam, water, oil, gas or chemical service.

For maintenance teams and process engineers, AWS-type strainer selection should be linked to the downstream equipment being protected and the expected contamination level during operation or commissioning.
