Mabapi le boemo ba ho pepa,Tekanyetso ea API 5Le totobatsa maemo a fapaneng a ho pepa bakeng sa liphaephe tsa tšepe tse se nang sekoli le liphaephe tse welded:

Phaephe ea tšepe e se nang seamless (boemo ba N): Boemo ba N bo bolela boemo ba kalafo bo tloaelehileng. Liphaephe tsa tšepe tse se nang seamless li etsoa hore li be le seamless pele li tlisoa ho etsa hore sebopeho sa phala ea tšepe se be le homogeneous, ka hona ho ntlafatsa thepa ea eona ea mechini le ho tiea. Ho etsa hore e be le seamlessness ho ka felisa khatello e setseng le ho ntlafatsa botsitso ba boholo ba phaephe ea tšepe.

Phaephe e tjheseditsweng (boemo ba M): Boemo ba M bo bolela kalafo ya thermomechanical ya phaephe e tjheseditsweng ka mora ho bopa le ho tjheseletsa. Ka kalafo ya thermomechanical, sebopeho se senyenyane sa phaephe e tjheseditsweng se a ntlafala, tshebetso ya sebaka sa ho tjheseletsa e a ntlafala, mme matla le botshepehi ba phaephe e tjheseditsweng nakong ya tshebediso di a netefatswa.
