Stainless Steel Perforated Tubes – 5 Proven Advantages For U

Stainless steel perforated tubes are precision-engineered filter cylinders made from high quality 304, 304L, 316 and 316L stainless steel perforated sheets. They can also be produced with mild Q195 steel, galvanized steel, aluminum or PVC-coated metal according to your project needs. With customizable hole patterns and diameters, stainless steel perforated tubes provide reliable sand control, liquid filtration and structural support in harsh working environments. Compared with ordinary straight-seam filter frames, stainless steel perforated tubes offer higher mechanical strength, excellent corrosion resistance and virtually no length limitation.
They are available in round tube, square tube and flat sheet forms for easy integration with different filtration systems and housing designs.

FAQs – Stainless Steel Perforated Tubes

Q1: What are stainless steel perforated tubes?

A1: Stainless steel perforated tubes are metal cylinders with evenly distributed holes on the tube wall. They are mainly used for filtration, sand control and as support cores for various filter elements.

Q2: Which materials are available?

A2: Common materials include AISI 304, 304L, 316 and 316L stainless steel. Mild steel, galvanized steel, aluminum and PVC-coated metals are also available for non-corrosive environments.

Q3: What hole shapes and sizes can you supply?

A3: We can produce round, square, rectangular, hexagonal, slotted and other special shapes. Hole size is typically 0.6–20 mm, or customized according to your filtration requirements.

Q4: Can stainless steel perforated tubes be customized?

A4: Yes. Diameter, length, wall thickness, perforation pattern, opening ratio and surface treatment can all be customized according to drawings or samples.

Q5: What is the usual packing method?

A5: Each tube is protected with plastic film, bundled securely and placed on pallets or in wooden boxes for safe sea or air shipment. Special packing and labels are available on request.

Q6: What information should I provide for a quotation?

A6: Please provide material grade, tube diameter, wall thickness, length, hole shape and size, open area, quantity and application (for example sand control, water filtration, etc.). We will recommend suitable specifications and offer a competitive price.
