API 5L X70 Inogamuchirwa Maitiro eKugadzira
Iyo X70 yekugadzira maitiro inosanganisira ese ari maviriisina musono uye yakasungwamafomu, ayo anogona kukamurwa se:
Pakati peizvi,SAWL(LSAW) ndiyo inonyanya kushandiswa mukugadzirwa kweX70 welded process uye inobatsira mukugadzirwa kwehombe-dhayamita, gobvu-yakavakirwa dimensional simbi pombi.
Kunyangwe pombi dzesimbi dzisina musono dzichiri kutorwa sesarudzo yakasarudzika nekuda kwehunhu hwadzo pasi pemamwe mamiriro akanyanya, dhayamita yepombi dzesimbi isina musono inogadzirwa kazhinji inogumira ku660 mm.Uku kudzikiswa kwesaizi kunogona kunetsa kana takatarisana nemapurojekiti makuru epombi yekufambisa kureba.
Kusiyana neizvi, chirongwa cheLSAW chinokwanisa kugadzira machubhu ane madhayamita anosvika 1,500 mm uye makobvu emadziro anosvika 80 mm.Uye mutengo unogona kuva unodhura-unobudirira pane simbi isina musono.
