Stainless Steel Seamless Pipe
Seamless tubes are mostly used to transport high pressure gas or fluid within the oil & gas, petrochemical, chemical and power industries. As the manufacturing process does not include any welding, seamless pipes are perceived to be more non-corroding and to withstand higher operating pressure and mechanical stress than welded steel pipes (according to ASME). Despite higher initial costs seamless pipes are more cost-effective when taking potential of defects, replacement and comprehensive tests for welded pipes into consideration.
Product Range: 6mm up to 327 mm
- The main perceived advantage of seamless pipes is that they don’t have a weld seam. Traditionally, the seam of welded pipes has been viewed as a weak spot, vulnerable to failure and corrosion. For many years, this fear was probably justified. However, in recent years improvements in the manufacturing process for welded steel pipes and other welded pipes have boosted the strength and performance of the weld seam to levels indistinguishable from that of the rest of the pipe.
- Seamless pipes provide peace of mind. Although there should be no issues with the seams of welded pipes supplied by reputable manufacturers, seamless pipes prevent any possibility of a weak seam.
- Seamless pipes have better ovality, or roundness, than welded pipes.
