Vim li cas thiaj li thauj khoom caj npab leak?
Kev xau hauv chaw thau khoom caj npab tuaj yeem ua rau muaj ntau yam ua rau muaj kev cuam tshuam rau sab hauv thiab sab nraud cuam tshuam:
{{01.} sab hauv cov laj thawj ntawm lub chaw thau khoom caj npab nws tus kheej
Cov Khoom Siv Cov Khoom Siv:
Siv cov ntaub ntawv substandard (e {{0} g .}}}, tsis muaj cov khoom siv tsis zoo) {{}
Kev tsis txaus siab PTFE Meem Dickness (qis dua 3 hli) hauv kev ua kom huv si ua rau hnav thaum ntxov los ntawm.
Kev tsim khoom tsis txaus ntseeg:
Low machining precision of swivel joint sealing surfaces (surface roughness >RA1 {.} 6μm) qhov tshwm sim hauv kev sib khi tsis ua haujlwm.
Tsis raug vuam (e {. g ., tsis tiav pipelines tsim kev xau.
Kev ua haujlwm tsis raug:
Tshaj dhau qhov kev tso cai ua haujlwm siab (e {..}}}}}}}}
Yuam kev sab caj npab dhau nws cov kev txwv tsis pub dhau los (e {{{}}}}}}}
Kev Tu Tsis Txaus:
Tsis saib xyuas lub foob pob hloov (dhau ntawm 1- xyoo lub neej) ua rau kev laus xyoo) ua rau kev laus xyoo) ua rau kev laus xyoo) ua rau kev laus xyoo
Ua tsis tiav rau calibrate cov tshuab qhuav qhuav (yuam hauv qab 0 {{. 5mpa) ua rau tsis tiav.
2.} Lwm yam lwm yam yuav pab txhawb nqa
NEEG KHO TSHUAB:
Collision from tank trucks (impact force >500n) deforms sab nraud npab, tawg welded pob qij txha .
Tsis raug cai lifting (siv crane hooks yam tsis muaj kev tiv thaiv padding) khawb ptfe linings .
Ib puag ncig corrosion:
Kev kub-kub oxidation (saum toj 200 degree) ua rau stainless hlau qhov chaw kom teev cia, kev hloov pauv tau compatibility.
Tshuaj lom neeg corrosion los ntawm atmospherian kuab paug (E {{} g}}}}}, so₂}
Huab Tais Cuam:
Khov ntawm cov dej hauv cov pob qij txha ntawm subzero kub (hauv qab-20}} degree) nthuav dav hlau tej koog.
Thermal cycling (temperature fluctuations >50°C) leading to loosened flange bolts (torque loss >30%).
3. Kev tiv thaiv kev ntsuas tiv thaiv kev kub ntxhov
Cov khoom siv thiab tsim kev txhim kho:
Qhia kom meej corrosion-resistant cov ntaub ntawv (e {{1} g} 2}} MR0175 ntawv pov thawj .
Nce vuam kev kuaj xyuas tus nqi (rau 100% ut / RT) rau cov pob qij txha tseem ceeb heev.
Kev qhuab qhia ua haujlwm:
Tswj hwm kev txwv siab (tso saib lub sijhawm tiag tiag ntawm kev tswj vaj huam sib luag) thiab txwv tsis pub dhau {}}
Siv cov wrorque wranges rau flange kev sib txuas (e {{}}}}} {munges) .
Yauj Tu:
Conduct quarterly ultrasonic thickness measurements on pipelines (thickness loss >20% yuav tsum hloov) .
Ua tag nrho xab NPO TEST rau txhua pob qij txha (sim siab 1 {{{}}}}}}}}}}}}} Ua haujlwm siab tsis pub dhau 5 feeb).
Kev tiv thaiv ib puag ncig:
Nruab qhov cuam tshuam kev cuam tshuam (lub zog muaj peev xwm muaj peev xwm ntau dua los yog sib npaug rau 1000j) nyob ib ncig ntawm cov caj npab thauj caj npab los tiv thaiv kev tsheb tsoo tsheb mus rau kev tsheb sib tsoo.
Siv cov tshuaj tiv thaiv corrosion (e . Cov khoom siv tam sim no, Zinc-Primer) rau recoating txhua 2 xyoo.
Cov Ntsuas Qhov Tseem Ceeb
Cov Khoom Siv Ua Raws: 100% (xyuas kom paub tseeb los ntawm cov ntawv xeem cov ntaub ntawv) .
Txij Nkawm Ua tiav Tus Nqi: Ntau dua los yog sib npaug rau 95% (saib xyuas ntawm cms tshuab) .
Kev Ntsuas Kom Tau: Tsawg dua los yog sib luag rau 1 teev (siv cov roj txheem siv hluav taws xob infrared) .
Los ntawm kev daws cov kev pheej hmoo sab hauv thiab cov kev pheej hmoo sab nraud, qhov tshwm sim ntawm kev thauj khoom hauv caj npab
