ASTM A 312 large diameter 1000MM thin wall 316l stainless steel pipe

The seamless stainless steel pipe is simply a pipe without a weld joint or a seam in contrast to welded or seam pipe. In this seam pipe, a seam or weld joint is a weak point of pipe limiting the strength of a pipe in order to strength of a weld joint. But, this seamless pipe does not even have any such joint and hence has uniform strength and structure throughout the body of a pipe. Therefore, the seamless stainless steel pipes are used in wide applications such as chemical, petrochemical, automotive, oil and gas, refinery, fertilizer, structural and mechanical applications.
