Tub Ntxhais Sib Txawv
| Lub hom phiaj | Cov Ntawv Thov | Phab Valve | Kev ntsuas hluav taws xob muaj ntau yam |
|---|---|---|---|
| API 6D | Roj thiab roj ntev ntev-ntev ntev (tawm-chaw nres tsheb sib kis) (Piv txwv li asme B31.4 / B31.8 Pipelines) |
Pipeline li qub (pob li qub, rooj vag li qub, thiab lwm yam) | Nps 4 txog 60 (Calibres Loj Tshaj Plaws) |
| API 608 | Chaw Nres Tsheb Cov Khoom Siv Piping (piv txwv li cov nroj tsuag tshuaj ntsuab) | Dav Hlau Pob Zeb Li Qub | Nps tsawg dua los yog sib npaug rau 24 (me me thiab nruab nrab caliber) |
Qhov sib txawv tseem ceeb:
API 6D yog rau kev kub siab, cov raj kav ntev thiab ntev thiab tsom rau kev nyab xeeb thiab xov xwm kev ncaj ncees;
API 608 yog rau cov kav xa ntawv siab qis thiab nruab nrab siab hauv cov nroj tsuag, nrog tsom rau kev lag luam thiab versatility.
Kev sib piv ntawm cov kev xav tau
1. Channel Tsim
API 6D: Yuav tsum tau tsim kev tsim puv txheej txheem (channel aperture.
API 60: Tso cai txo cov qauv tsim (channel aperture nrog
| Lus | API 6D | API 608 |
|---|---|---|
| PDissure duav duav | Hoob 150 / Chav Kawm 1500 | Chav kawm 150/300 nkaus xwb |
| Kev sealing | Xoom so site hauv ob qho tib si kev qhia (yuav tsum tau rau cov kev mob siab) | Unidirectional foob (feem ntau nyob hauv qab nteg) |
| Tsawg Siab Hermetic | Yuav tsum tau (0.6 MPa roj nruj ntsuas) | tsis tas yuav |
3. Cov ntaub ntawv thiab cov qauv
API 6D:
Lub cev lub cev yuav tsum tau tiv thaiv sulphur corrosion (NACE MR0175 yuav tsum muaj cov ntawv pov thawj rau cov leejulfur-muaj cov kev pabcuam);
Valve rooj yog welded nrog nyuaj alloys (piv txwv li stellite).
API 60 8:
Tso cai muag (ptfe / peek) lossis hlau ntsaws ruaj ruaj;
Cov Khoom Siv Khoom Siv (Carbon Hlau / Stainless Hlau).
4. Tsav tsheb thiab tua hluav taws
API 6D:
Tau tshaj pneumatic-hydraulic txuas, hluav taws xob tswj;
Yuav tsum muaj cov ntawv pov thawj hluav taws (API 6FA / 607).
API 60 8:
Los ntawm txhais tes / cab iav / hluav taws xob;
Hluav taws tsis kam ua tsis tau.
Qhov sib txawv hauv kev sim cov qauv
| Test Hom | API 6D | API 608 |
|---|---|---|
| Plhaub mus xeem | 1.5 × pn (dej siab) | 1.5 × pn (dej siab) |
| Kev Ntsuas Siab Tshaj Tawm | 1.1 × pn (dej siab) | 1.1 × pn (dej siab) |
| Khab mov | Ntau dua los yog sib npaug rau 10minutes (txuas ntxiv dhau chav kawm 600) | Ntau dua lossis sib npaug zos rau 3minutes |
Kev ntsuas tshwj xeeb: API 6d yuav tsum tau ib qho kev sim qia seal (tsis muaj xau ntawm 1.1 lub sij hawm siab).
Kireciner Kev Xaiv Kev Xaiv
Xaiv API 6D:
Roj thiab roj ntev ntev ntev (ntau dua lossis sib luag rau NPS 4);
Sulphur-muaj xov xwm, kev kub siab (chav kawm 300 lossis ntau dua) lossis cov hluav taws kub kev nyab xeeb.
Xaiv API 608:
Sab hauv tsob ntoo txheej txheem kav dej (tsawg dua los yog sib npaug rau NPS 24);
Kev ua kom dawb huv, tsawg rau nruab nrab siab (chav kawm 150/300) thiab tus nqi rhiab scenarios.
Kev sib raug zoo synergistic: API 60 4 pob li qub tseem yuav tsum tau ntsib ASME B16.34 siab-ntsuas kub thiab tsis hloov chaw.
Ntsiab lus: API 6D yog tus qauv kev nyab xeeb tshwj xeeb rau cov roj muaj txiaj ntsig zoo rau cov roj thiab roj kev daws teeb meem rau me me thiab nruab nrab dav dav dav dav. Cov tub ntxhais ntawm qhov sib txawv yog cuam tshuam hauv txoj kab uas hla hauv lub siab, siab pab them, kev lag luam sal thiab pheej hmoo.
