Difference between Seamless and Welded Tube & Pipe Seamless and welded are mainly two types stainless steel tube & stainless steel pipe, there is a debate whether seamless is better than welded for a long time. Although with improved metallurgy and welding processes in welded tubes, the arguments typically focus on structural integrity and corrosion resistance in weld
Manufacturing Process of Welded, Drawn and Seamless Pipe The two major categories for tubing and pipe are seamless and welded. The major difference being the seam that is on a welded tube and not on a seamless tube just as the names indicate. Seamless pipe has the increased ability to withstand pressure; because there is no weld seam it is equally strong around the entire circumference.
Mechanical tubing is manufactured to typical mechanical tube properties in accordance with ASTM A513 and ASTM A519 specifications. Some of the most common types of mechanical tubing are Drawn Over Mandrel tubing (DOM) , Hot Rolled/Finished Seamless tubing (HRS) , Cold Drawn Seamless tubing (CDS) , Hot Rolled or Cold Rolled Electric Weld tubing
Seamless tube, seamless square tube, Application of square There are mainly three kinds of forming technology of seamless square tube:hot-rolled, cold-drawn and welded. For the cold drawn square tube, the ability of withstanding localized concentrated load is weak, the welding process produced pipe welds are the weak link, do not apply to the construction of high-end residential buildings.

Figure 1 A typical induction-welded or electric-resistance-welded (ERW) tube has weld beads on the ID and OD. A scarfing tool can remove the OD weld bead. A scarfing tool can remove the OD weld bead. I made a joke of the question, but this really is a serious topic.China Machinery Manufacturing S355j0h Square Seamless We have three manufacture lines,which cost more than 3 million dollars.The 3 lines make full sizes of square and rectangular tubes:20mm*20mm-600mm*600mm square tubes;20mm*30mm-600mm*800mm rectangular tubes, thickness:1.5mm-35mm,over 2800 kinds of specifications.
