API 5L X70 pombi ndeye premium giredhi pombi zvinhu muAPI 5L yakajairwa zvakatemwa. Iyo inonziwo L485 pombi, sezvo iri goho simba
zvishoma mu485 Mpa (70,300 psi). API 5L X70 inovhara marudzi ekugadzira asina musono uye akasungwa (RW, SAW) marudzi, ese akaiswa.
yekufambisa mafuta uye gasi.
API X70 kabhoni simbi mutsetse pombi inogona kutsanangurwa sesimbi pombi ine yakakwira kabhoni yemukati uye alloying compound. API 5L X 70 kabhoni simbi isina musono pombi Pamusoro pekutsvaga huwandu hwezvimwe zvinhu zvakaita sesarufa, phosphorus, nezvimwewo, alloy yayo ine yakakwira manganese nesilicon. Kuwedzerwa kwezvinhu izvi zvese kunobatsira kuvandudza michina yeX70 kabhoni simbi pombi.
Izvi zvinogona kuonekwa kubva kune yakaderera goho simba (485 MPa) yeAPI 5L X70 Kirasi B LSAW chubhu. Iyo zvakare ine hushoma tensile simba re635 MPa. Iyo yepamusoro yeAPI 5L X70 SCH 40 DSAW machubhu inobatwa nemhando dzakasiyana, senge dema, anticorrosive mafuta, inopisa-dip galvanized kana kutonhora-galvanized. Zvichienderana nekushandiswa chaiko kweX70 PSL2 spiral chubhu, tinogona kukurudzira kurapwa kwepamusoro kwepamusoro kune vatengi vedu vanoremekedzwa. Semuyenzaniso, iyo galvanized coating paX70 PSL1 giredhi pombi inoratidza yakanakisa corrosion resistance.
