Perforated Tube

Precision Cylindrical Filter Elements for Liquid, Gas & Solid Filtration

Perforated Tube with Composite Mesh and Etched Screen Options for Filtration

Perforated tube filters, also known as cylindrical filters, are precision metal filtration components manufactured by perforating or chemically etching metal sheets into specific hole patterns, then roll-forming them into cylindrical shapes. Depending on the base material, they are available as stainless steel tube filters, copper tube filters, black wire mesh tube filters, galvanized steel tube filters, and more.

These rigid, self-supporting filter elements combine structural strength with precise open area, making them ideal for fluid and gas filtration, flow control, and structural support in demanding industrial environments.

Perforated Tube Filter Types

Perforated Tube

Perforated + Woven Mesh Tube

Etch Screen Tube

Perforated Tube

Perforated Tube is made by perforating a stainless steel sheet with uniform round, square, or slot holes, then rolling and welding it into a cylindrical shape. It offers high mechanical strength, rigidity, and a large open area, ideal for coarse filtration and mechanical protection.

Specification

Material: carbon steel, stainless steel 304, 304L, 316, 316L, super duplex UNS S32750, UNS S32760, tin-plated carbon steel, aluminum, titanium, etc.
Thickness: 0.3–5 mm
Tube diameter: 10–800 mm
Length: Customized
Hole pattern: round, square, hexagonal, slot, and others.
Ends: Both ends open, but available for customized flange or fittings.

Applications

  • Exhaust system
  • Oil and gas filtration
  • Hydraulic and pneumatic systems
  • Mechanical protection of sensors or filters
  • Structural support for multi-layer filters

Features

  • High rigidity and pressure resistance
  • Large flow area and low pressure drop
  • Customizable hole type and pattern
  • Durable and easy to clean

Perforated + Woven Mesh Tube

The composite perforated mesh tube consists of an outer or inner perforated plate combined with one or more layers of woven wire mesh. This design combines strength and precision – the perforated layer provides mechanical support, while the wire mesh layer delivers fine filtration.

Specification

Material: carbon steel, stainless steel 304, 304L, 316, 316L, super duplex UNS S32750, UNS S32760, tin-plated carbon steel, aluminum, titanium, etc.
Thickness: 0.3–5 mm
Tube diameter: 10–800 mm
Length: Customized
Hole pattern: round, square, hexagonal, slot, and others.
Ends: Both ends open, but available for customized flange or fittings.

Applications

  • Fine filtration in hydraulic systems
  • Polymer and chemical filtration
  • Petrochemical, pharmaceutical, and food industries
  • Backwashable filter cartridges

Features

  • Strong, precise structure
  • High flow rate and filtration accuracy
  • Reusable and easy to clean
  • Works in high-pressure, high-temperature environments

Etch Screen Tube

The etched screen tube is produced by chemical etching (photo-etching) a metal sheet to form ultra-precise micro-holes or patterns, then rolling and welding into a cylinder. It provides very fine and accurate openings that cannot be achieved by mechanical perforation.

Specification

Pattern: Round, slot, hexagonal, or custom micro-geometry
Structure: Single-layer etched plate, welded seam, both ends open.

Customizable according to your requirements.

Applications

  • Micro-filtration in electronics and the semiconductor industry
  • Polymer melt and fine liquid filtration
  • Precision flow control and atomization systems
  • Laboratory and medical filtration devices

Features

  • Highly accurate, uniform apertures
  • Smooth surface without burrs or deformation
  • Ideal for precision micro-filtration
  • Excellent repeatability and dimensional stability
