Our TP201 Stainless Steel Welded pipe manufactured from cold-forming process using coils of steel sheet with automated spiral welds. Great strides were made in quality control, testing, joints and protective coatings. Welded steel pipe is available in wide ranges of sizes and properties of the steel. These ERW Pipes carry high strength, ease of installation, high flow capacity, leak resistance, long service life, reliability and versatility, and economy.

 

 

 

A312 TP201 Welded pipe ship marking:

 

Markings will adhere to prescribed specifications in A999/A999M and shall include the NPS or OD and schedule number or average wall thickness, heat number, and NH (when hydrotesting is not performed) and ET (when eddy-current testing is performed) or UT (when ultrasonic testing is performed). The marking shall also include the manufacturer’s private identifying mark, the marking requirement of section 12.3 on Hydrostatic or Nondestructive Electric Test, if applicable, and whether seamless (SML), welded (WLD), or heavily cold-worked (HCW). For Grades TP304N, TP201H, TP321H & TP347H, the marking shall also include the heat number and heat-treatment lot identification.
