FAQ
Dab tsi yog qhov txawv ntawmP110thiab C110?
Qhov sib txawv tseem ceeb ntawm API 5CT P110 thiab C110 yog qhov ntawdC110yog qib siab - steel qib tshwj xeeb tsim los rautiv thaiv hydrogen sulfide (H₂S) corrosion, thaumP110yog ageneral-lub hom phiaj siab- zog steel qibuas tsis muaj acid kuj.
Dab tsi yog ISO sib npaug ntawm API 5CT?
Tus txheej txheem thoob ntiaj teb sib npaug ntawm API 5CT yogTS EN ISO 11960.
Cov qauv no, lub npe hu ua ISO 11960: Petroleum thiab natural gas industries - Cov kav hlau siv los ua cov kav dej lossis cov kav dej rau qhov dej, yog tsim los ntawm International Organization for Standardization (ISO). Nws cov ntsiab lus kev ua tau zoo raws li API 5CT, ua kom muaj kev sib nrig sib paub thiab kev sib raug zoo ntawm kev tsim khoom, kev tshuaj xyuas, thiab kev ua haujlwm ntawm cov roj zoo casing thiab tubing thoob ntiaj teb.
