Cevi iz nerjavečega jekla niso samo iz različnih materialov, kot naprimer 210 nerjaveče jeklo, 304 nerjaveče jeklo, 316 nerjaveče jeklo, itd., imajo pa tudi varjene cevi iz nerjavečega jekla in brezšivne cevi iz nerjavečega jekla. Med obema je določena razlika, dobesedno razlika med šivom in brezšivom, ampak v resnici, v tem procesu je bistvena razlika.
Obstajajo razlike v temperaturi proizvodnega procesa. Postopek izdelave brezšivnih cevi iz nerjavečega jekla je prebijanje luknje v gredico iz nerjavečega jekla pri temperaturi 2200 ° F. Pri tej visoki temperaturi, 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. Poleg tega, 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, in debelina stene celotnega oboda je zelo enakomerna. Zato so varjene cevi boljše od brezšivnih.

Poleg tega, med obema so razlike v kemični sestavi, saj sestava jekla za izdelavo brezšivnih cevi izpolnjuje le osnovne zahteve astm. Jeklo, ki se uporablja pri izdelavi varjenih cevi, vsebuje kemične sestavine, primerne za varjenje, kot je silicij, žveplo, mangan, kisik, in elementi, pomešani s trikotnim feritom v določenem razmerju, 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. Zato, 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, in pri nakupu je treba sprejeti določene presoje.
