Perforated Tubes for Cylindrical Filters: Round, Square, Slotted, Hexagonal Holes

Perforated tubes are cylindrical filter elements featuring uniformly distributed openings in various shapes, such as round, square, slotted, or hexagonal holes, depending on the specific filtration or structural requirement. These tubes are typically classified by their perforation pattern, hole size, pitch, and material type, which can include stainless steel or other alloys. Designed for durability and high performance, perforated tubes are widely used in applications such as filtration systems, hydraulic systems, exhaust systems, water treatment, oil and gas, and chemical processing.

DIMENSIONS AND SPECIFICATIONS:

• Tube Diameter: The tube diameter typically ranges from 10 mm to 300 mm. Commonly used diameters include 25 mm, 50 mm, 75 mm, 100 mm, 150 mm, and 200 mm.

• Tube Length: Standard lengths are available from 500 mm to 6000 mm. Custom lengths can be manufactured upon request.

• Wall Thickness: Common wall thicknesses range from 0.5 mm to 5 mm. Frequently selected thicknesses include 1.0 mm, 1.5 mm, 2.0 mm, and 3.0 mm.

• Hole Diameter (Perforation Size): The hole diameter usually ranges from 0.5 mm to 20 mm. Popular hole sizes are 1 mm, 2 mm, 3 mm, 5 mm, and 10 mm.

• Open Area Percentage: The open area percentage typically varies between 20% and 60%, depending on the specific application requirements.

• Materials: Commonly used materials include stainless steel (grades 304, 316, 316L), brass, and copper.

• Hole Patterns: Perforations can be round, square, slotted, or hexagonal, chosen based on filtration efficiency or structural strength needs. The arrangement of the holes can be straight, staggered, or spiral.

• Customization: Customization is possible to meet specific client requirements for dimension tolerances and perforation patterns.
