Round Hole Pattern Perforated Steel Pipe For Petrol Textile Galvanized Steel
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.
Forward filter is good at producing spiral welded steel perforated pipe, we started this business ten years ago.
Spiral perforated pipe is welded by perforated steel roll which is revolving on the production line, different with straight perforated pipe. Welding ling is longer, so it can endure 30% more pressure.
Normally spiral welded steel is made of stainless steel like 201, 304, 316 which is used in petrol or textile, but it can also used in filtration, better than straight welded perforated pipe. In some situation it can also use galvanized steel or carbon steel. In this case we need minimum order quantity.
Different application need different steel like carbon steel, stainless steel, galvanized steel.
Perforation pattern usually is round holes, there is straight line holes and staggered line holes, different open area need different diameter center distance. 15%-33% open area is common configuration. Formulas for your reference
A: 60° perforation pattern or staggered pattern: hole diameter * hole diameter*90.69% / hole center distance * hole center distance
B: 180° perforation pattern or straight pattern: hole diameter * hole diameter * 78.5% / horizontal diameter center distance * vertical diameter center distance
C: Other special cases as follows
