Roostevabast terasest torude tarnija Wenzhou Kaixin Hiinas
Roostevabast terasest keevitatud toru on teatud tüüpi roostevabast terasest torud, mis on õmblusest kokku keevitatud. Seda kasutatakse tavaliselt rakendustes, kus on suur tugevus, vastupidavus, ja korrosioonikindlus on vajalikud, näiteks surveanumate ehitamisel, soojusvahetid, ja torusüsteemid. Roostevabast terasest keevitatud torude tootmisprotsess hõlmab esmalt roostevabast terasest lameda riba vormimist torukujuliseks. Seejärel kuumutatakse riba servad kõrgele temperatuurile ja sulatatakse kokku elektrivoolu või suure energiaga kiirte abil.. See protsess loob tugeva, pidev õmblus toru pikkuses.
Roostevabast terasest keevitatud toru on saadaval erinevates suurustes, seina paksused, ja roostevaba terase klassid, sealhulgas austeniit, ferriitne, ja dupleksklassid. Klassi ja seina paksuse valik sõltub konkreetsest rakendusest ja torude nõutavatest mehaanilistest omadustest.
