Pipe Strainers FAQ – Pipetech Supplies

Below you'll find answers to the most common questions we receive about our pipe strainers collection. If you need further technical guidance or help selecting the right strainer for your application, our team is ready to assist.

What is a pipe strainer and what does it do?

A pipe strainer is a protective device installed in a pipeline to filter out debris, sediment, and solid particles from the fluid flow. It safeguards downstream equipment such as pumps, valves, heat exchangers, and meters from damage or blockage, helping to maintain system efficiency and reduce maintenance costs.

What types of pipe strainers does Pipetech Supplies offer?

Our collection includes Y-strainers and basket strainers in a range of materials and connection types. We stock options suitable for various pressure ratings and pipe sizes, covering applications from light commercial plumbing through to heavy industrial process lines. For specific product availability, browse the collection or contact our team.

How do I choose the correct size of pipe strainer?

Match the strainer's nominal bore to the pipe size in your system. You should also consider the required flow rate, operating pressure, and the type of media being filtered. If you're unsure, provide us with your system specifications and we'll recommend a suitable unit.

What materials are your pipe strainers available in?

We supply strainers manufactured from cast iron, ductile iron, stainless steel, bronze, and other engineering-grade materials. The choice of material depends on factors such as the fluid type, temperature, pressure class, and whether the application involves potable water or corrosive media.

What pressure ratings do your strainers support?

Our range includes strainers rated to recognised engineering standards such as PN16 and PN25 for metric flanged connections, as well as ANSI 150 and ANSI 300 for imperial flanged systems. Threaded (BSP) strainers are also available for lower-pressure installations. Always verify that the strainer's rated pressure meets or exceeds your system's maximum operating pressure.

Can I use your pipe strainers in potable water systems?

Selected strainers in our range carry WRAS approval, making them suitable for use in potable (drinking) water applications. Check the individual product listing for WRAS certification details, or contact us and we'll confirm which models are approved.

What is the difference between a Y-strainer and a basket strainer?

A Y-strainer has a compact, angled body and is well suited to applications with lower debris loads or where space is limited. It can be installed in both horizontal and vertical pipelines. A basket strainer has a larger filtration area, making it better for systems with higher debris volumes or where longer intervals between cleaning are preferred.

How often should a pipe strainer be cleaned or maintained?

Cleaning frequency depends on the volume and type of debris in your system. As a general rule, inspect the strainer screen shortly after commissioning and then at regular intervals based on observed contamination levels. A noticeable increase in pressure drop across the strainer is a reliable indicator that the screen needs cleaning.

What mesh or perforation size should I select for my strainer screen?

Screen selection depends on the particle size you need to capture and the sensitivity of your downstream equipment. Finer mesh screens offer greater protection but may require more frequent cleaning. Consult the equipment manufacturer's recommendations for maximum allowable particle size, and we can help match you to the right screen specification.
