  • Manufacturing Process of Stainless Steel Seamless Tube

    Manufacturing Process of Stainless Steel Seamless Tube

    Stainless seamless steel tube is completely homogenous tube, the properties of which give seamless tubing more strength, superior corrosion resistance, and the ability to withstand higher pressure than welded tubes. This makes stainless seamless tubing more suitable for critical applications in harsh environments. When bending and torsion strength are the same, the weight of ss pipe is lighter. Permanent Steel is one of the toppest professional stainless seamless steel pipe manufacturer. We provide additional customer services such as tube cutting and polishing.
