API 5L X52 Ibyiciro
Ukurikije urwego rwa PSL nuburyo bwo gutanga, X52 irashobora gushyirwa mubyiciro bikurikira:
PSL1: X52;
PSL2:X52N cyangwa L360N;X52Q cyangwa L360Q;X52M cyangwa L360M.
Muri PSL2, ibaruwa yinyongera yerekeza ku bwoko bwo kuvura ubushyuhe ibikoresho bigomba gukorerwa mbere yo kubyara bwa nyuma.Urashobora kubonauburyo bwo gutangamunsi kubindi bisobanuro.

Ku muyoboro wa PSL 2, ibyuma bizicwa kandi bigakorwa hakurikijwe imyitozo myiza.
Igiceri cyangwa isahani ikoreshwa mugukora umuyoboro wa PSL 2 ntigomba kubamo gusudira.
API 5L X52 Uburyo bwo gukora
Imiyoboro ya X52 irashobora kubyara hakoreshejwe uburyo butandukanye bwo gukora imiyoboro kugirango ihuze ibyifuzo bitandukanye.
Kugirango umenye byinshi kubisobanuro byamagambo ahinnye yo Gukora,kanda hano.
SAWLni igisubizo cyiza kuribinini-diameter, bikikijwe n'inkutaimiyoboro y'icyuma.
Amagambo "SAWL"na"LSAW"byombi bivuga Longitudinal Submerged Arc Welded, ariko bivugwa mu turere dutandukanye. Ibinyuranye, ijambo" LSAW "rikoreshwa cyane mu nganda.
Umuyoboro wa LSAW urashobora gusudwa kabiri kubera ubushobozi buke bwibikoresho mu gukora umuyoboro munini wa diameter, kandi gusudira bigomba kuba hafi 180 ° bitandukanye.
