Basket Strainer Replacement Basket in 304 Stainless Steel (AISI 304 (1.4301)) is used for replacing the perforated or mesh-lined basket inside permanent simplex and duplex basket strainers that protect pumps, heat exchangers and meters on pipelines. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Basket Strainer Replacement Basket Is Used
- Cooling & process water: basket strainers ahead of plate heat exchangers and chillers.
- Oil & fuel terminals: transfer-line strainers in front of pumps and meters.
- Chemical plants: pump suction protection on corrosive lines.
- Marine & power: duplex strainers that are cleaned without stopping flow.
Ordering Basket Strainer Replacement Basket in 304 Stainless Steel
- Body size & make: Basket outside diameter and depth must match the strainer body exactly so nothing bypasses.
- Perforation & liner: 3–4 mm perforation for strength, with a 20–40 mesh liner when finer straining is needed.
- Open area ratio: 300–400 % of the pipe area keeps pressure drop low between cleanings.
Mistakes to Avoid with Basket Strainer Replacement Basket
- Choosing too fine a liner for the dirt load, so the basket blinds within hours.
- Fitting a shorter basket than the body needs, leaving a bypass gap at the bottom.
