Dab tsi yog qhov sib txawv ntawm API 5L X65 PSL1 thiab PSL2?
Lub ntsiab sib txawv ntawm API 5L X65 PSL1 thiab APIL X65 PSL2 yog nyob rau theem ntawm cov khoom lag luam tshwj xeeb thiab tsim khoom. Cov hauv qab no yog cov ncauj lus piav qhia:
Qib Khoom Tshwj Xeeb Qib:
PSL1 thiab PSL2 yog ob theem sib txawv cov khoom lag luam tshwj xeeb nyob rau hauv API 5L tus qauv. Qhov yuav tsum tau ua rau PSL2 muaj kev nruj dua thiab npog cov qauv tswj hwm zoo dua.
Tshuaj lom neeg muaj pes tsawg leeg tshuaj thiab cov neeg kho tshuab:
PSL2 muaj cov kev cai nruj dua rau cov khoom siv tshuaj lom thiab cov khoom siv neeg siv neeg ntau dua PSL1. PSL2 yuav tsum tau meej dua cov tshuaj lom neeg tswj hwm thiab siab dua kev ua tau zoo dua cov khoom siv.
Cuam tshuam cov khoom:
PSL1 tsis tas yuav muaj kev cuam tshuam kev ua haujlwm kuaj, thaum PSL2 yuav tsum tau muaj tag nrho cov kev ua haujlwm tshwj tsis yog muaj qhov ntau dua nruab nrab ntawm qhov loj me 0 degree cuam tshuam cov haujlwm.
Hydrotesting thiab tsis yog-kev sim ua haujlwm:
Raws li API 5L tus qauv, cov yeeb nkab kab yuav tsum yog Cegrotested ceg los ntawm ceg, thaum PSL1 tsis xav tau kev tshuaj xyuas tsis yog cov tsis muaj kev puas tsuaj.
Yeeb nkab kawg kev kho mob:
Cov yeeb nkab kawg ntawm PSL2 yuav tsum yog sandblasted, thaum PSL1 tsis.
Txhawm rau muab cov ntsiab lus, API 5L X65 PSL2 yog xav tau ntau dua li cov tshuaj chemical, cov khoom siv tshuab hluav taws xob ua tau zoo dua li PSL1 qib cov yeeb nkab. Thaum xaiv cov khoom lag luam tsim nyog yuav tsum tau xaiv raws li cov kev thov tshwj xeeb thiab cov kev xav tau.
