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 Galvanized steel perforated tube for hydraulic filter Carbon steel perforated tubing is usually hot dipped galvanized to enhance its corrosion resistance property. Perforated Stainless Steel Pipe is corrosion resistant, rust resistant, recycled, ideal for automotive exhaust applications. 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. Because carbon steel is susceptible to corrosion, it is typically used in either unexposed applications or protected with a coating. Coatings such as paint and powder are applied after perforating and completely protect the material. Zinc based coated metals (i.e. Galvanized, Galvannealed, etc.) on the other hand, are produced and supplied as such from the mill and may not completely protect the material where its carbon core is exposed during the perforating process. Commonly Perforated Carbon Steel Types Commercial Steel (HR, CR, GALV) A low cost steel that has good drawing, forming, and welding qualities, moderate strength, but is subject to strains, fluting, and breaks due to aging. To reduce the affects caused by aging, Drawing Steel is recommended. Drawing Steel (HR, CR) A steel with a greater degree of ductility and uniformity of properties than Commercial Steel providing improved performance during manufacturing. This type is recommended for use when stretcher strains or fluting during fabrication are objectionable and/or consistency of performance is important. Forming Steel (GALV) A steel with lower strength and higher elongation than Commercial Steel. Recommended when stresses from forming either crack or weaken Commercial Steel.
