Pipeline Filtration

Bucket Type Strainer 6" Fabricated

Fabricated bucket type strainer with MS (Mild Steel) body and SS304 stainless steel basket. 40 mesh filter element with 0.4mm perforated sheet. Flanged ends per ASME B16 Class 150. For pipeline filtration, debris removal, and pump protection.

Quick Summary

Bucket Type Strainer = Pipeline filter with removable basket for debris capture. 40 mesh = ~400 micron filtration (removes sand, scale, rust). MS body for economy, SS304 basket for corrosion resistance. Fabricated construction for large sizes. Flanged ends for easy installation. Used before pumps, heat exchangers, and sensitive equipment.

Frequently Asked Questions

What is a bucket type strainer?

A bucket type strainer is a pipeline filter with a removable basket (bucket) that captures debris and particles from flowing fluid. The basket can be removed for cleaning without disconnecting the pipeline. Bucket strainers are used for coarse to medium filtration in water, oil, and process fluid systems. They are larger than Y-strainers and handle higher flow rates.

What is 40 mesh filter?

40 mesh means 40 openings per linear inch, which corresponds to approximately 0.4mm (400 micron) opening size. This is a medium-fine filtration level suitable for removing sand, scale, rust particles, and debris from water and process fluids. Finer meshes (80, 100) remove smaller particles but have higher pressure drop.

What is the difference between fabricated and cast strainer?

Fabricated strainers are made by welding steel plates and pipes, while cast strainers are made from molten metal poured into molds. Fabricated strainers are: (1) More economical for large sizes, (2) Easier to customize, (3) Shorter Production schedule, (4) Suitable for lower pressures. Cast strainers are stronger and preferred for high-pressure applications.

Why use SS304 basket in MS body strainer?

SS304 basket provides corrosion resistance where it contacts the fluid, while MS body reduces cost. The basket is the working element that filters debris and needs corrosion resistance. The body only contains pressure and can be MS with proper coating. This combination offers good performance at lower cost than full stainless steel construction.
