Specifikacija bešavnih kućišta

Materijali koji se koriste za API 5CT kućište nafte bešavne čelične cijevi prvenstveno su podijeljeni u različite razrede, a najčešće bićeL80, J55 i N80. Besprijekorne čelične cijevi nude dug radni vijek i mogu održavati svoje performanse u ekstremnim uvjetima, ispunjavajući zahtjeve visokog - tlaka i visokog - temperaturnih okruženja u naftnoj i plinskoj industriji.
