Manufacturing Process of Stainless Steel Pipes/Tubes:
The process commences with the formation of welded mother tube on the tube mill from imported and tested prime quality stainless steel strips. The latest TIG multi electrode welding technique is employed for superior weld quality and 100% Fusion, with argon purging, No filler metal added.
Hypodermic tubing produced by weldding from stainless steel strip , after weldding , then arrange coil hydro forming cold drawing with inner plug, final the tube insider and outside both surface are smooth , and tolerance also excellent .
