API 5L GR.B stands rau "Basic," uas txhais tau hais tias cov yeeb nkab yog tsim los rau cov ntawv thov uas tsis tas yuav tsum tau siv cov alloys siab zog.
Nta API 5L GR.B seamless steel yeeb nkab muaj ntau yam khoom uas ua rau nws tsim nyog siv rau hauv kev lag luam hluav taws xob. Cov khoom no muaj xws li:
Lub zog siab: Nrog qhov tsawg kawg nkaus tawm lub zog ntawm 245 MPa (35,500 psi) thiab lub zog tensile yam tsawg kawg nkaus ntawm 415 MPa (60,200 psi), API 5L GR.B high-strength steel yeeb nkab tuaj yeem tiv taus ib puag ncig siab.
Corrosion Resistance: Cov hlau siv nyob rau hauv API 5L GR.B qaub kev pab cuam yeeb nkab yog heev resistant rau corrosion. Thiab nws tuaj yeem raug coated nrog FBE, 3PE / 3LPE, cov xim pleev xim dub, thiab cov kua roj vanish ntshiab, muab kev tiv thaiv corrosion thiab oxidation ntxiv rau cov yeeb nkab.
Durability: API 5L GR.B Carbon Steel Kab Yeeb yog qhov ruaj khov thiab tuaj yeem tiv taus qhov kub thiab txias. Qhov no ua rau nws zoo tagnrho rau kev siv hauv kev lag luam hluav taws xob qhov twg cov kav dej yuav raug rau qhov chaw muaj kev ntxhov siab.
API 5L GR.B Carbon Steel Gas Pipe yog dav siv hauv kev lag luam hluav taws xob rau kev thauj mus los ntawm cov roj av, roj, thiab dej. Nws kuj yog siv rau hauv lwm yam lag luam xws li kev tsim kho thiab kev tsim khoom.
GNEE yog tus xa khoom loj ntawm API 5L GR.B Carbon Steel Kab Yeeb Nkab, thiab peb muab cov kav hlau zoo rau peb cov neeg siv khoom thoob ntiaj teb raws li lawv xav tau.
