Lub ntsiab lus ntawm lub npe
API 5L: Tus qauv tsim los ntawm lubLub koom haum American Petroleumrau cov kav dej.
PSL2: Khoom Specification Qib 2. Nws txhais tau hais tias cov yeeb nkab muajkev cai nruj dua(rau chemistry, lub zog, thiab kev sim) dua PSL1.
X70: Covyam tsawg kawg nkaus yield zogyog 70,000 psi. Qhov no txhais tau tias cov hlau muaj zog heev.
Seamless: Cov yeeb nkab tsis muaj welded seam. Nws yog tsim los ntawm cov khoom siv steel hlau, ua rau nws muaj zog thiab txhim khu kev qha rau siab - siv zog.
Ntsiab nta & qhov zoo
Siab zog: Muaj peev xwm tswj tau siab heev sab hauv.
Zoo rau cov xwm txheej nyuaj: Tsim nyog rau sab ntug dej hiav txwv, arctic, lossis siab - kev pabcuam qaub (yog tias tau teev tseg).
ntseeg tau: Tsis muaj vuam seam txhais tau tias muaj kev pheej hmoo tsawg dua ntawm kev ua tsis tiav.
Kuaj Tag Nrho: Raws li PSL2, nws tau soj ntsuam ntau dua.
