API 5L X42, izwi kandi nka L290, ni ubwoko bw'umuyoboro ukoreshwa mu nganda za peteroli na gaze.
Imiterere y'ibikoresho niimbaraga nkeya z'umusaruro wa psi 42,100(290 MPa) naimbaraga nkeya zo gukurura za psi 60,200(415 MPa). Ifite urwego rumwe ruri hejuru ya API 5L Grade B kandi ikwiriye gukoreshwa mu mbaraga ziciriritse.
X42 ikunze gukorwa muri Seamless, SSAW, LSAW, na ERW. Hari irangi n'irangiza bihari kugira ngo bihuze n'ibisabwa byihariye.
Ibisabwa mu gutanga
Bitewe n'imiterere y'ibicuruzwa ndetse n'urwego rwa PSL, bishobora gushyirwa mu byiciro bikurikira:

N: Guhindura ibintu mu buryo busanzwe;
Q: Yazimye kandi irangwa n'imitekerereze;
M: Uburyo bwo kuvura hakoreshejwe thermomechanical.
Uburyo bwo gukora
X42 yemerera gukora ibintu bikurikira:
Niba ubona ko izi nyuguti zihinnye zigoye kumva, reba inyandiko zacu zivuga kuriamagambo ahinnye akoreshwa ku miyoboro y'icyuma.
