Perforated Steel Round Tube for Filters

Perforated metal sheets are used popular in filter elements processing, either as filter screen or as filter backing tube. Metal tubing processed from thick sheet with perforated round holes combines the structural strength, uniform opening and lasting properties. The welded steel tubing is suitable for filter cores which can withstand quick flow of liquid and support the outside filter mesh layer. Micron slotted hole perforated steel tubing is used as filter cylinder or casing tube in oil drilling, mine developing and other industries. The welding types for perforated tubes are welded butt welded seam and spiral lock seam welding. We also offer welding options including spot welded tubes, longitudinal/straight seam tubes, straight seam tack welded tubes, abutted seam tubes, straight lock seam tubes, and more.

Made with advanced digital controlled equipment, perforated metal tube has high precision, low difference and strong filtering. The diameter perforated ranges from 0.3mm to 100mm.

Perforated pipes/ tubes are mainly used in sifting and grading in mine development and other industrial uses. We also offer square tubing for modern building decoration designs and cable tray covers.

Materials: Hot dipped zinc coated steel or stainless steel sheets.
Typical opening for filter cylinders: Round.
