Introduction
There is a never-ending debate whether seamless is better than Welded Steel Tubing For Sale. The arguments typically centre on structural integrity and corrosion resistance of the weld, severity of the intended service, NDT and inspection requirements and delivery time [1]. In reality, both production methods can provide the necessary quality and service life, corrosion resistance and reliability. Generally welded tubes are less expensive, have narrower tolerances, thinner nominal wall thickness, better concentricity (outer/inner diameter OD/ID), higher internal surface quality and are often chosen since they can be produced in longer lengths with larger diameters. Seamless tubes are needed where heavy wall thickness is combined with small diameters making forming of plate or strip complicated and where the standard specifically specifies seamless.
They also allow larger diameters and
longer lengths to be produced. Although Welded Steel Tubing For Sale dominate the market, seamless
tubes and pipes are still used. The main reasons other than conservatism are that some
very heavy wall sizes can sometimes be too thick to form to the required profiles and that
some traditional standards still specify seamless. The long term future and growth
of stainless steel tubular products will without a doubt lie in welded production.
