Pipe Perforation

Direct Stamping on Pipe

Our Process Flow

Our innovative process of direct stamping on pipes provide you better cost, quality, and design flexibility.

Our production line is equipped with roll forming machine and ERW welding machine, enabling the raw material to be either metal coils or pipes.

The rolled and welded pipe will then be cut to length and swaged to specification before being perforated on our customized stamping machine.

The ability to perforate directly on pipes benefits your product and operation through a number of ways. Production cost will be marginally lower with the shorter process flow. The process is capable of producing:

  • Pipes with good finishing and near perfect weld with no material protrusion
  • Single-piece pipes with smooth inner surface and no joints
  • Pipes with better roundness & full 360° perforation
  • Pipes that are swaged before being perforated
  • Longer pipes with both ends swaged, any location perforated


Perforated pipes can be used in a variety of applications, for example:

- Automotive silencer
- Filtration system elements (Engine oil filter, filter center tube, well screen, etc)
- Aeration system tubes
- Chemical processing system
