Description
High-Performance ASME Class 150 Basket Strainer for Industrial Pipeline Protection
Le 150LB WPB Basket Strainer with a 316 Stainless Steel Screen and Raised Face (RF) Flanged Ends is designed to protect pumps, valves, flow meters, heat exchangers, compressors, and other critical pipeline equipment from harmful debris and contaminants. Manufactured from ASTM A234 WPB carbon steel and fitted with a 316 stainless steel removable basket screen, this industrial basket strainer provides excellent filtration efficiency, long service life, and easy maintenance for demanding process systems.
At VUT Vannes, we manufacture premium-quality basket strainers that comply with international standards, delivering reliable performance in the oil & gas, petrochemical, power generation, water treatment, chemical processing, marine, and general industrial sectors.
Why Choose a 150LB WPB Basket Strainer?
Industrial piping systems often contain welding slag, rust, pipe scale, sand, and other solid particles that can damage expensive downstream equipment. Installing a Class 150 basket strainer is one of the most cost-effective ways to improve system reliability and reduce maintenance costs.
The removable SS316 filter basket captures contaminants while allowing clean process media to flow with minimal pressure loss. Once the basket becomes dirty, it can be removed, cleaned, and reinstalled without replacing the entire strainer.

How a Basket Strainer Works
A basket strainer is installed upstream of critical equipment to remove unwanted solid particles from the process fluid.
During operation:
- Fluid enters the strainer body.
- Contaminants are trapped inside the stainless steel basket.
- Clean fluid continues downstream.
- When the pressure differential increases, the cover is opened and the basket is removed for cleaning.
- The cleaned basket is reinstalled, and the system resumes normal operation.
This simple filtration process significantly extends the service life of pumps, valves, meters, and heat exchangers.

Frequently Asked Questions (FAQ)
What is the purpose of a basket strainer?
A basket strainer removes solid particles from liquids to protect pumps, valves, meters, and other pipeline equipment from damage and wear.
Why use a 316 stainless steel screen?
A 316 stainless steel screen provides excellent corrosion resistance, high strength, and a long service life, especially in chemical, marine, and water treatment applications.
What is the difference between a basket strainer and a Y strainer?
A basket strainer offers a larger filtration area and higher dirt-holding capacity, making it ideal for horizontal pipelines with higher flow rates. A Y strainer is more compact and commonly used where installation space is limited.
Can the screen be customized?
Yes. STV Valves offers custom perforation sizes, wire mesh options, wedge wire baskets, and micron ratings to meet specific process requirements.
Which industries commonly use Class 150 basket strainers?
These strainers are widely used in oil & gas, petrochemical, power generation, chemical processing, water treatment, marine, HVAC, pulp & paper, and general industrial piping systems.
