API X70 erogba irin laini paipu le ti wa ni asọye bi irin paipu pẹlu ga erogba akoonu ati alloying yellow. API 5L X 70 carbon steel pipe paipu Ni afikun si awọn oye ti awọn eroja miiran gẹgẹbi imi-ọjọ, irawọ owurọ, ati bẹbẹ lọ, alloy rẹ ni akoonu giga ti manganese ati silikoni. Afikun ti gbogbo awọn eroja wọnyi ṣe iranlọwọ lati mu ilọsiwaju awọn ohun-ini ẹrọ ti paipu carbon carbon X70.
Eyi ni a le rii lati agbara ikore kekere (485 MPa) ti API 5L X70 Class B LSAW tube. O tun ni agbara fifẹ to kere ju ti 635 MPa. Ilẹ ti API 5L X70 SCH 40 DSAW tubes ni a ṣe itọju ni awọn oriṣiriṣi oriṣiriṣi, gẹgẹbi dudu, epo anticorrosive, galvanized gbona-dip galvanized tabi tutu-galvanized. Ti o da lori lilo pato ti X70 PSL2 spiral tube, a le ṣeduro itọju dada ti o dara julọ fun awọn alabara ti o ni ọwọ.
