Strong Rewashable Strainers of Pipeline Coarse Filtration

Some manufacturing processes of pipe systems contain solid particles which may flow down the pipeline and damage equipment, therefore a strainer filter is needed to capture a larger amount of particles as coarse filtration to ensure equipment stable process. Meanwhile, they are easy to be installed, taken out, and backwashed to avoid opening from being bogged down.

A Perforated filter also named temporary strainer or strainer filter, is made of metal perforated plates and woven mesh that is welded together. They are available in lots of shapes to suit different pipe systems, including perforated basket strainers, perforated conical strainers, and perforated plate strainers. Other different strainer shapes also can be customized upon request.

Advantages:

Easy to process, install, remove, and clean
Catch up and hold almost particles to protect key equipment
Strong support layer as a firm structure for long term operation
Professionabespoke design service with high adjust-ability
Smooth surface without burr
Unit holes for high filtration accuracy
Excellent porosity and permeability with large flow per unit area
Easy to produce with high cost-efficiency
Standard stainless steemateriawith good corrosion resistance
Non-toxic and harmless

Basket Strainers

Compared to cone strainers, basket strainers feature a cylinder shape with a flat top and are normally made of woven wire mesh, perforated plates, or a combination of both. It is available in the standard basket, slanted basket, with or without handles.

PFS-B1: Perforated basket strainer with flat bottom

PFS-B2: Perforated filter with arch bottom

PFS-B3: Perforated basket strainer with bolted handle

PFS-B4: Perforated basket strainer with welded handle

PFS-B5: Perforated basket strainer with round handle bar

PFS-B6: Perforated basket strainer with flange for bolt installation

PFS-B7: Slanted basket strainer with flat handle

PFS-B8: Slanted basket strainer with round handle

Cone Strainers

Cone strainers, also known as conicastrainers or hat strainers, are installed in the inlet port of the relief valve, decompression valve, water levevalve, and other equipment.

PFS-C1: Conicastrainer with perforated layer and inner mesh layer

PFS-C3: Conicafilter ith reinforced top ring and handle tail

PFS-C4: Flat-top conicastrainers without handle tail

Plate Strainers

Also known as disc strainers, or plate strainers, it plays an important role to protect downstream equipment during initiastart-up and normaperiods. Although the contact surface of the plate strainer is smaller than the above two types, it is easier to quicker to remove from the two flanges of pipelines.
