API 5L X70 Kauv Steel Pipe

API 5L X70 Kauv Steel Pipeyog cov pa roj carbon ntau dua ntawm cov yeeb nkab qib nrog cov khoom zoo corrosion nyob rau hauv ntau qhov cua.
API 5L x70 kauv carbon steel yeeb nkab muaj txog li 0 22-0.28% carbon, mus txog 1-1.2% manganese, mus txog 0.03% phosphorus, thiab Tus nqi ntawm leej faj, npib tsib xee, chromium thiab tooj liab.
Thaum lub sij hawm khoov kev sim, tsis muaj kab nrib pleb yuav tsum tshwm sim nyob rau hauv ib feem ntawm cov yeeb nkab thiab tsis muaj qhib yuav tsum tshwm nyob rau hauv lub welds. Phab ntsa thickness thiab lwm yam specifications ntawm API 5L x70 carbon steel yeeb nkab yog 6.4-38.1 hli. Lub raj yuav tsum tau hloov mus rau ib txoj kab uas hla ntsuas nrog ib tug neeg kho tshuab caliper uas muaj ib tug ncig cross-section nrog ib txoj kab uas hla ntawm 6.4 mm thiab ib tug ntev li ntawm 0.03 m, ntsuas lub sab saum toj ntawm lub pob qij txha.
