FAQ:
Koj xaiv li cas ntawm 45K, 60K, thiab 75K rau API 6A flanges?
- Rau 5,000 psi taub qab -welded flanges, 45K tau txais. Rau 10,000 psi ib qho kawg kev sib txuas, 60K lossis siab dua yog xav tau. Rau 15,000 psi thiab siab dua, 75K lossis siab dua yog xav tau.
Yuav Ua Li Cas Xaiv PSL Qib rau API 6A Flanges?
- PSL 1 xav tau daim ntawv qhia txog cov khoom siv kho tshuab.
- PSL 2 ntxiv kev cuam tshuam toughness.
- PSL 3 yuav tsum tsis yog- kuaj kev puas tsuaj (ultrasonic los yog radiographic kuaj) thiab tshuaj lom neeg muaj pes tsawg leeg tsom xam rau txhua lub siab-cov kabmob.
- PSL 4 muaj cov kev cai nruj tshaj plaws thiab yuav tsum tau kuaj xyuas kev ua tau zoo nyob rau hauv cov kev pabcuam simulated.
Qhov txawv ntawm API 6A 45K thiab 60K flanges yog dab tsi?
- 45K muaj lub zog tawm los ntawm 45,000 psi; 60K muaj lub zog tawm los ntawm 60,000 psi. Cov khoom siv 60K muaj zog dua thiab kim dua.
Vim li cas thiaj yuav tsum 5000 psi WN (Vuam Neck) flanges siv RTJ (Nplhaib Hom Joint) foob?
- Ntawm ultra-siab siab ntawm 5000 psi, tus qauv RF (Raised Face) sealing nto yog qhov ua rau to. RTJ system, siv lub nplhaib hlau gasket, muab lub foob ruaj khov thiab txhim khu kev qha nyob rau hauv cov xwm txheej uas muaj qhov kub siab, corrosion, thiab kev co.
45K carbon steel flanges puas tuaj yeem siv rau hauv cov pa roj qaub uas muaj H₂S?
- Lawv tsis tuaj yeem siv ncaj qha. Koj yuav tsum xaiv cov ntaub ntawv raws li NACE MR0175 tus qauv (xws li A694 F45 NACE lossis Duplex Stainless Steel F53).
API 6A 6B thiab 6BX flanges yog dab tsi?
- API 6B flanges yog lub nplhaib- hom sib koom ua ke (RTJ) flanges nrog qhov siab tshaj plaws ntawm 3,000 PSI.
- API 6BX flanges yog RTJ flanges uas tswj tau ntau qhov siab dua, nrog rau qhov tsawg kawg nkaus lub zog ntawm 75,000 PSI.
Dab tsi tshwj xeeb kev txiav txim siab siv thaum siv 45K 5000 psi flanges ntawm ntug dej hiav txwv?
- Khoom siv: Anti-corrosion coatings + Stainless hlau / Duplex Stainless hlau.
- Qib: Yam tsawg kawg nkaus PSL 2 + PR2 kev xeem.
- Vuam: Tag nrho kev nkag mus welds + 100% Tsis yog-Kev Ntsuas Kev Ntsuas (NDT).
- Bolting: Siab - lub zog bolts (A193 B7 / B16).
Yuav ua li cas xaiv ib qho ntawm 45K 5000 psi thiab 35K 2000 psi flanges?
- 2000 psi (35K): Tsim nyog rau qis - kev sib sau ua ke thiab kev sib kis, nrog rau cov ntawv siv lub taub hau zoo; nws yog qhov kev xaiv nyiaj txiag ntau dua.
- 5000 psi (45K): Yuav tsum muaj rau siab - siab ntau lawm, kev txhaj tshuaj roj, sib sib zog nqus- dej hiav txwv ua haujlwm, thiab qhov chaw ua haujlwm qaub; nws muaj kev nyab xeeb zoo dua thiab ua haujlwm ntev dua.
