Bending Perforated Steel Tube
21mm tube
Wall thickness: 2mm
Perforated with 4mm and 6mm holes.
Pipe length 340mm
Material: Steel
Used exposed to heat and oil

100mm OD Perforated Steel Tube
100mm OD perforated steel tubing
Used as shielding around 1-3/4" exhaust pipe that runs at 1000F.
The perforated tubing connects to a piece of 4" ID flexible exhaust hose.
Perforations allow for air to be drawn in the flexible hose to cool the inner pipe. This type of perforations is rigid and allows air flow.
Length varies from 9-12" lengths.

Perforated tubes for making high performance exhaust systems for autos.
OD 30 x Thickness 1 mm x Length 6 meter
Perforation type: hole size 3mm, triangler stitch 4mm

Carbon Steel Perforated Tube

Carbon steel perforated tubing is usually hot dipped galvanized to enhance its corrosion resistance property.

Perforated Stainless Steel Pipe

Perforated steel tubes are manufactured with round, square, slot holes in straight or staggered designs.

Materials for Perforated Steel Tubes

Perforated Tube is a kind of Welded Steel Pipe made of mild steel or 409, 439, 304, 316 Stainless Steel perforated materials.

Choosing the proper steel materials according to the properties:
Stainless steel is the most corrosion resisting material, while its alloys vary specifically to suit different work environment.

Carbon Steel is the most corrosive and therefore, the least expensive of the three most commonly perforated metals. Produced into coil form by roller leveling to a desired thickness either once while the steel is still hot or again after it has cooled, each of the Carbon Steel types listed below are referred to as either Hot Rolled or Cold Rolled (ex. Cold Rolled Commercial Steel). The difference in processes result in products that differ in terms of cost, quality, and mechanical properties. In short, Hot Rolled is typically less expensive and produced in thicker gauges 7-16, whereas, Cold Rolled provides tighter tolerances, better surface finishes, and while it can be produced in practically any gauge, it is most readily available in thinner gauges 14-28.
