Guangzhou Steel News: seamless steel pipe joints straight substitution can not do in order to
Structural steel in theory, should be the same, the difference is not great, as good as seamless Longitudinal rules pipe centroid might not in the center, so when used as a compression member with particular attention, defective weld pipe the probability is relatively high, an important part of not substitute seamless pipe, seamless pipe wall thickness is limited processing do not do very thin (seamless pipe thickness than the average thickness of the same diameter), in many cases seamless pipe material use efficiency is better, especially the large-diameter pipe.
The biggest difference is seamless and welded pipe used in gas or liquid pressure transmission (DN). Guangzhou Steel
