Audio Perforated Stainless Cylinder , Stainless Steel Perforated Metal Pipe

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.

Stainless Steel Support Cores can be used in instrument filters housing. Some of them are spiral welded perforated tubes, they are called stainless steel support cores, some are seamless perforated tubes.

Forward Brand Support Cores for Different Application with Wire Mesh Cover is high quality which is produced by Forward filter, we have long time experience on producing stainless steel support cores. We can produce not only perforated cores but also wire mesh over screens, there are some levels of wire mesh screens sintered with perforated cores.

Forward Brand Stainless Steel Support Cores can be not only 304, 304L, but also 316, 316L, same with wire mesh cylinder. We can offer Hemmed seam or dot welding, all of them can offered certain application.

We can offer high range diameter such as 10mm-1000mm support cores

Another situation is used in textile mill, with burr outside, support core can offer solid textile roll

Forward Filter is a factory with more than 10 years’ experience producing Stainless Steel Spiral Welded Perforated Tube in Petrolium Filtration with High Pressure. Our material is higher quality than normal level of other factories and we offered many big brand machinery companies in our domestic market and abroad market

Stainless Steel Spiral Welded Perforated Tube is applied in many industries area like petroleum refining filtration or oil producing filtration, hydraulic filtration, food filtration producing, drainage system, Light decoration, Vehicle Exhausts or Acoustical Dampening products.

Besides Stainless steel, we also can use other materials like galvanized steel , carbon steel and other alloy.

Perforation hole pattern is variety, which can be round, square and blinds

As for the seam style, we usually use spiral formed, if you have more than one hundred thousand meters require, we can accept custom-made.
