Wire Mesh Filter Cylinders & Tubes

What is a wire mesh filter cylinder used for?

Cylindrical mesh elements act as support cores, protective shrouds, coarse pre-filters and flow distributors. They may carry no filtration rating alone or pair with inner fine media. Applications span strainers, hydraulic suction guards, catalyst support, fluidized beds and custom OEM assemblies. Define whether the part is structural, filtration-rated or both — that drives mesh selection and wall construction.

When the cylinder is structural only, open area and wire gauge can be relaxed; when it must retain particles, weave and micron mapping drive the build — list both mechanical and filtration requirements on the RFQ.

How are mesh tubes and cylinders manufactured?

Flat mesh is cut, rolled to diameter and joined by seam welding or locking; caps, flanges or threaded ends may be added. Multi-layer cylinders combine coarse outer and fine inner mesh for graded filtration. Perforated metal support can be added for high differential pressure duties. Process choice depends on diameter, length, alloy and cleanliness requirements — confirmed per drawing.

Long cylinders may use spiral seam orientation for strength; short inserts may use straight seam with minimal distortion. Caps welded flush or extended for handle tabs are quoted from your assembly drawing — note weld symbol requirements if applicable.

Which dimensions matter most on your RFQ?

Outer diameter, inner diameter, overall length, mesh specification (count, weave, material), seam orientation, end finish (open, closed, flanged, threaded), tolerance class and quantity. For replacement parts, photos of ends and caliper readings on OD/ID accelerate review. Note operating temperature, media and whether the element is cleaned in place.

For hydraulic suction screens, note flow direction and whether the element sees pulse or steady differential pressure. For reactor internals, note cleaning frequency and whether the mesh is replaced or cleaned in place.

SS304 vs SS316L for mesh cylinders — when to upgrade?

SS304 suits many water, air and neutral fluid supports. SS316L is preferred for chlorides, aggressive cleaners, food/pharma CIP and many chemical streams. Higher alloys are quoted for specialty corrosion or temperature — list media composition and peak temperature on the inquiry.

Passivation or pickling after welding may be required for food or pharma service — state surface finish and cleanliness requirements. Material certificates for base metal and weld filler can be included when specified on the PO.

What should I send for an accurate cylinder quotation?

Drawing or sample with OD, ID, length, mesh spec, end details, quantity and installation notes. Mark critical tolerances and seal surfaces. MOQ and unit price depend on diameter, seam type and end machining — confirmed per quote after specification review.

Annual volume and repeat part numbers help us plan seam tooling and mesh lot alignment. First-article dimensional reports are available when your validation file requires measured OD, ID, length and mesh spec confirmation.

What MOQ and lead time should I expect?

Standard diameters in SS304/SS316L mesh may ship faster than first-time threaded or multi-layer designs. Samples or first-article photos are offered when validation is required — schedule confirmed per project. Share target delivery date on the RFQ.
