API 5L X60 (L415) ni umuyoboro w'umurongoifite imbaraga nkeya z'umusaruro zigera kuri 60.200 (415 MPa) zo gukoreshwa mu buryo bwo gutwara imiyoboro mu nganda za peteroli na gaze.
X60bishobora kuba ubwoko butandukanye bw'imiyoboro y'icyuma ishongeshejwe, akenshi LSAW (SAWL), SSAW (SAWH), na ERW.
Bitewe n'uko ifite imbaraga nyinshi kandi iramba, umuyoboro wa X60 ukunze gukoreshwa mu miyoboro miremire inyura mu turere cyangwa mu mirimo yo gutwara abantu mu turere dutandukanye no mu bindi bice bigoye.
Botop Steelni umwuga mu gukora imiyoboro y'icyuma ya LSAW ifite inkuta nini kandi ifite uburebure bubiri iherereye mu Bushinwa.

Ibisabwa mu gutanga
Bitewe n'imiterere y'aho imodoka igeze ndetse n'urwego rwa PSL, X60 ishobora gushyirwa mu byiciro bikurikira:
PSL1: x60 cyangwa L415;
PSL2: X60N, X60Q, X60M cyangwa L415N, L415Q, L415M.
N: Bigaragaza ko ibikoresho bihinduka mu buryo busanzwe. Gushyushya icyuma ku bushyuhe runaka hagakurikiraho gukonjesha umwuka. Kunoza imiterere mito n'imiterere ya mekanike y'icyuma no kongera ubukomere n'ubudahangarwa bwacyo.
Q: Bisobanura Kuzimya no Gushyushya. Gushyushya icyuma ugishyushya ku bushyuhe runaka, ugikonjesha vuba, hanyuma ukongera ugishyushya ku bushyuhe bwo hasi. Kugira ngo ubone uburinganire bw'imiterere yihariye ya mekanike, nko gukomera no gukomera.
M: Bigaragaza uburyo bwo gutunganya ubushyuhe n'ubuhanga. Guhuza uburyo bwo gutunganya ubushyuhe n'ubuhanga kugira ngo imiterere y'icyuma irusheho kuba myiza n'imiterere yacyo. Birashoboka kongera imbaraga n'ubukomere bw'icyuma mu gihe ukomeza kugira ubushobozi bwo gusudira neza.
Uburyo bwo gukora API 5L X60
Uburyo bwemewe bwo gukora imiyoboro y'icyuma kuri X60
Niba ubona ko izi nyuguti zihinnye zigoye kumva, reba inyandiko zacu zivuga kuriamagambo ahinnye akoreshwa ku miyoboro y'icyuma.
Ibyiza bya SAWL (LSAW)
Niba ukeneye umuyoboro munini w'icyuma ufite uburebure bunini, amahitamo ya mbere niSAWL (LSAW) umuyoboro w'icyuma. Umuyoboro w'icyuma wa LSAW ushobora gukorwa mu bunini bugera kuri mm 1500 z'umurambararo na mm 80 z'ubugari bw'urukuta, ukaba ushobora guhaza ibyo imiyoboro ikora kure ikeneye mu mishinga minini.
Byongeye kandi, mu gihe cyo gukora, umuyoboro w'icyuma wa LSAW ukoresha ubushuhe bwo kugonga bugizwe n'impande ebyiri (DSAW) inzira, ituma umushongi wo gusudira uba mwiza.
