Bešavne cijevi od nehrđajućeg čelika

Proces proizvodnje bešavnih cijevi od nehrđajućeg čelika sastoji se od prerade gredica od nehrđajućeg čelika u cijevi potrebne veličine toplim valjanjem, hladnim valjanjem ili hladnim izvlačenjem. Ova cijev može učinkovito izbjeći slabosti spojeva koje se mogu pojaviti tijekom zavarivanja. Ima visoku vlačnu čvrstoću i granicu tečenja te može učinkovito izdržati unutarnje i vanjske pritiske pod visokim tlakom i visokim temperaturama. U usporedbi s tradicionalnim zavarenim cijevima, bešavne cijevi nemaju zavarene šavove, tako da je struktura jednoličnija i stabilnija, smanjujući pukotine ili probleme zamora koji mogu biti uzrokovani nedostacima zavarivanja. Bešavne cijevi/cijevi od nehrđajućeg čelika imaju dobru plastičnost i žilavost tijekom hladne obrade i lako se izvode operacije obrade kao što su zavarivanje, rezanje, savijanje i oblikovanje te mogu zadovoljiti posebne potrebe različitih područja.
