Hloov lub npe
Pipeline (Pipeline) hloov mus rau pipeline (piping)
Pipeline: feem ntau yog hais txog kev thauj mus los ntev ntawm cov roj thiab cov kav dej.
Pipeline: feem ntau yog hais txog ib lossis ib tus lej ntawm qee yam ntawm qee qhov ntev ntawm cov yeeb nkab.

kev hloov hauv cov qauv uas tau hais tseg
1, cov qauv siv tshiab API 6DX "pipeline valve actuator thiab installation cov qauv", API6FA "Valve Fire Resistance Test Specification", API 6FD "Kuaj Valve Hluav Taws Kub Resistance Test Specification", API 607 "tig 1/4 lub lis piam li qub thiab tsis yog xim hlau Lub rooj zaum ntawm qhov kev ntsuas hluav taws xob yuav tsum tau ua, "qhov yuav tsum tau ua ntawm API6D valve actuator txhawb kev tsim, kev teeb tsa, thiab siv lub valve yuav tsum tau coj los ntawm API 6DX / 6FA / 6FD / 607 thiab lwm yam qauv.
2, ntxiv NACE MR 0175-2005 "kev lag luam roj thiab roj - roj thiab roj ntau lawm nyob rau hauv ib puag ncig ntawm sulfur dioxide khoom xaiv" tus qauv. Cov qauv no yog cov txheej txheem xaiv cov khoom siv, tshem tawm NACETM 0284 "Txoj Kev Xeem Txuj Ci - Pipeline Steel thiab Cov Nkoj Siab rau Hydrogen Cracking Resistance". Cov qauv xaiv cov khoom siv los hloov cov qauv kuaj cov khoom. Qhov no yog ib qho tseem ceeb rau lub chaw tsim khoom valve, API 6D tus qauv yuav tsum tau ua raws li tus qauv NACE MR0175 xaiv cov khoom siv hydrogen sulfide-resistant, feem ntau, thiab tsis muab tso rau hauv cov txheej txheem lees paub cov ntaub ntawv thiab rov qab ua cov ntawv xeem.
3, ntxiv "ASME Boiler Pressure Vessel Code, Volume II, Part D: Mechanical Properties". Qhov no yog 23rd tsab ntawm tus txheej txheem kom nce ASME VIII (1), (2) lub ntuj derivation ntawm cov qauv tsim, uas yog, tsim cov ntaub ntawv thiab lwm yam mechanical zog thiab tso cai kev nyuaj siab raws li ASME Volume II, Tshooj D rau txiav txim.
4, nce ISO 6892-1 tensile xeem cov qauv thiab ISO15614-7 vuam xeem cov ntaub ntawv hlau Part 7 cladding txheej txheem ntsuam xyuas cov qauv.
5, lwm txoj kev: tus thawj ASMT A388, ASTM A435 ntawm ultrasonic xeem txoj kev standardized nrog ASTMA578A / A578M, ASTMA609 / A609M tus qauv hloov;
-
hloov nyob rau hauv terminology thiab txhais
Terminology los ntawm cov qub version ntawm 36 los yog (38) nce mus rau lub tshiab version ntawm 50
1, ntxiv "thaiv thiab ntshav valve (blockandbleed valve BB)";
Hloov lub ntsiab lus ntawm "pressurized qhov chaw" kom paub meej tias qhov chaw siab ntawm lub valve muaj xws li yam tsawg kawg nkaus lub cev valve, qhov kawg kev sib txuas, bolts / lub kaus mom thiab qia, thiab lub qia yog ib feem ntawm lub siab;
3, txhais cov ncej (ncej) thiab qia (stem), thiab ua kom sib txawv ntawm lawv;
4, Chav Kawm Siab (Hnub Siab) yog txhais raws li qhov ntsuas siab ntsuas los ntawm ASMEB16.34, nrog "Class" ua raws li tus lej los qhia. Tshem tawm tus qauv qub ASME rated class (ASMErating class) no siv; rho tawm qhov nominal siab (PN) qib (nominal siab) qhov kev siv no, kom API 6D thiab ISO tsis cuam tshuam;
5, ntxiv cov ntsiab lus ntawm lub sij hawm vuam: cov kev ua ub no ntawm cov khoom, cov khoom thiab kev sib dhos. Qhov no yog tag nrho-welded valve welding yog suav tias yog cov txheej txheem ntawm tag nrho cov sib dhos.
6, ntxiv cov cim thiab cov ntawv luv
BB-Block thiab Bleed (Block thiab Bleed)
QSL-QualitySpecification Level (QualitySpecification Level)
TC-test pas nrig (Visual Test)
Deleted: HV-Vickers Hardness
