API 5L X42, izwi kandi nka L290, ni ubwoko bw'umuyoboro ukoreshwa mu nganda za peteroli na gaze.
Ibikoresho ni aimbaraga ntoya yumusaruro wa 42.100 psi(290 MPa) na aimbaraga zingana zingana na 60,200 psi(415 MPa).Nicyiciro kimwe kirenze API 5L Icyiciro B kandi gikwiranye nimbaraga ziciriritse.
X42 isanzwe ikorerwa muri Seamless, SSAW, LSAW, na ERW.Kwambara no kurangiza birahari kugirango byuzuze ibisabwa byihariye.
Ibisabwa
Ukurikije uko ibintu bimeze no kurwego rwa PSL, birashobora gushyirwa mubyiciro bikurikira ：
PSL1: X42 cyangwa L290;
PSL2: X42R, X42N, X42Q, X42M cyangwa L290R, L290N, L290Q, L290M;
Inyuguti z'umugereka wa PSL2 buri kimwe kigaragaza uburyo butandukanye bwo kuvura ubushyuhe.
R: Kuzunguruka;
N: Gusanzwe;
Q: Kuzimya no kurakara;
M: Ubuvuzi bwa Thermo-mashini.
Uburyo bwo gukora
X42 yemerera inzira yo gukora ikurikira:
Niba ubona aya magambo ahinnye bigoye kubyumva, reba icyegeranyo cyingingo kuriamagambo ahinnye yimiyoboro yicyuma.
Botop Steel irashobora kuguha urutonde rwubunini bwa pipe nkuko bigaragara mumbonerahamwe ikurikira.

API 5L X42 Ibigize imiti
Ibigize imiti ya PSL 1 Umuyoboro ufite t ≤ 25.0 mm (0,984 muri.)
Ibigize imiti ya PSL 2 Umuyoboro ufite t ≤ 25.0 mm (0,984 muri.)
Kubicuruzwa bya PSL2 ibyuma bisesengurwa hamwe nakarubone ingana na 0,12%, karubone ihwanye na CEpcmirashobora kubarwa ukoresheje formula ikurikira:
CEpcm= C + Si / 30 + Mn / 20 + Cu / 20 + Ni / 60 + Cr / 20 + Mo / 15 + V / 15 + 5B
Kubicuruzwa bya PSL2 ibyuma bisesengurwa hamwe naibirimo karubone> 0,12%, karubone ihwanye na CEllwirashobora kubarwa ukoresheje formula ikurikira:
CEllw= C + Mn / 6 + (Cr + Mo + V) / 5 + (Ni + Cu) / 15
Ibigize imiti hamwe na t ＞ 25.0 mm (0,984 muri.)
Ibi birashobora kumvikana hifashishijwe imiti yavuzwe haruguru.
API 5L X42 Ibikoresho bya mashini
Ibintu byiza
Ikizamini cya tensile ni ikizamini cyingenzi kumiterere yubukorikori bwibyuma, bushobora gupima umusaruro, imbaraga zingana, no kurambura ibipimo byingenzi.
Imbaraga za X42 ni 42.100 psi cyangwa 290 MPa.
X42 imbaraga zingana ni 60,200 psi cyangwa 415 MPa.

Igihe cyo Kugerageza
Ingano zose zicyuma zidafite kashe kandi zisudira hamwe na D ≤ 457 mm (18 muri.):igihe cyo gukora ≥ 5s;
Umuyoboro w'icyuma usudira D> 457 mm (18 muri.):igihe cyo gukora ≥ 10s.
Inshuro Yikigereranyo
Buri muyoboro w'icyumakandi ntihazabaho kumeneka kumubiri weld cyangwa umuyoboro mugihe cyizamini.
Imikazo y'ibizamini
Umuvuduko wikizamini cya hydrostatike P ya aumuyoboro wicyumairashobora kubarwa ukoresheje formula.
P = 2St / D.
Sni ihuriro.agaciro kangana nimbaraga ntarengwa zerekana umusaruro wicyuma cya xa ijanisha, muri MPa (psi);
tni uburebure bwurukuta rwerekanwe, bugaragara muri milimetero (santimetero);
Dni diameter igaragara hanze, yerekanwe muri milimetero (santimetero).
Igenzura ridafite ishingiro
Kubona SAB, uburyo bubiri,UT(ibizamini bya ultrasonic) cyangwaRT(ibizamini bya radiografiya), mubisanzwe bikoreshwa.
ET(ibizamini bya electromagnetic) ntibikoreshwa kuri SAW tubes.
Ubudodo bwo gusudira ku miyoboro isudira yo mu byiciro ≥ L210 / A na diameter ≥ 60.3 mm (2.375 in) igomba kugenzurwa bidasubirwaho kubyimbye n'uburebure bwuzuye (100%) nkuko byavuzwe.

Ibicuruzwa Bifitanye isano
Kuva yashingwa mu 2014,Botop Steelyabaye umuyobozi wambere utanga imiyoboro ya karubone mumajyaruguru yUbushinwa, izwiho serivisi nziza, ibicuruzwa byiza, nibisubizo byuzuye.
Isosiyete itanga imiyoboro inyuranye y’ibyuma bya karubone n’ibicuruzwa bifitanye isano na byo, birimo icyuma, ERW, LSAW, hamwe n’icyuma cya SSAW, ndetse n’umurongo wuzuye w’ibikoresho bya flanges na flanges.Ibicuruzwa byayo bidasanzwe birimo kandi amavuta yo mu rwego rwo hejuru hamwe na austenitis ibyuma bitagira umuyonga, bigenewe guhuza ibyifuzo byimishinga itandukanye.
