What is the difference between stainless steel welding and stainless steel seamless pipe

Stainless steel pipes not only have different materials, such as 210 inôksa, 304 inôksa, 316 inôksa, etc., fa koa manana Stainless vy welded sodina sy Stainless vy seamless fantsona. Misy fahasamihafana manokana eo amin'izy roa, ara-bakiteny ny maha samy hafa ny seam sy ny seamless, fa raha ny tena izy, misy fahasamihafana lehibe amin'ity dingana ity.
Misy fahasamihafana eo amin'ny mari-pana amin'ny fizotran'ny famokarana. Ny dingan'ny famokarana fantsona tsy misy vy tsy misy vy dia ny mametaka lavaka ao amin'ny billet stainless vy amin'ny mari-pana 2200 ° F. Amin'ity mari-pana ambony ity, tool steel becomes soft and spiral formed from the hole through stamping and drawing. The disadvantage of stainless steel pipes produced by this process is that the wall thickness of the pipes is uneven and the eccentricity is high. In addition, the wall thickness difference of seamless pipes is larger than that of welded pipes. Stainless steel welded pipes are made from precise cold-rolled sheets, and this manufacturing process results in a very small tolerance on the wall thickness of the pipe, ary ny hatevin'ny rindrina amin'ny circumference manontolo dia tena mitovy. Izany no mahatonga ny sodina welded tsara kokoa noho ny sodina seamless.

In addition, misy fahasamihafana eo amin'ny singa simika eo amin'izy roa, satria ny firafitry ny vy amin'ny famokarana fantsona tsy misy dikany dia mahafeno ny fepetra fototra amin'ny astm. Ny vy ampiasaina amin'ny famokarana fantsona welded dia misy singa simika mety amin'ny lasantsy, toy ny silicone, solifara, manganese, oksizenina, ary singa mifangaro amin'ny ferrite telozoro amin'ny ampahany iray, which can produce a weld melt that is easy to transfer heat during the welding process, so that the entire weld seam is fully welded. Ary noho izany, the manufacturing process requirements for welded pipes will be higher, and the cost will be higher. Steel pipes lacking the above chemical components will produce unstable factors, leading to quality problems in stainless steel pipes. Just like seamless pipes, various unstable factors may occur during the welding process, making it difficult to weld firmly and thoroughly. So for welded and seamless pipes, we need to have a certain understanding in order to make easy choices, because different manufacturing processes and steel requirements can lead to price differences, and certain judgments need to be made when purchasing.
