IbASME B16.5 Chav Kawm 1500 qhov muag tsis pom flangeyog ib qho khoom siv hlau uas siv los kaw qhov kawg ntawm qhov siab -siab piping system lossis siab hlab ntsha nozzle. Tsis zoo li tus qauv weld caj dab lossis plam- ntawm flanges, lub qhov muag tsis pom flange tsis muaj qhov nruab nrab rau cov dej ntws. Hloov chaw, nws ua haujlwm raws li qhov kawg ntawm cov txheej txheem -cap, nqus cov kev ntxhov siab tseem ceeb uas tau ua los ntawm kev kub siab sab hauv thiab ntsia liaj qhov rooj. HT PIPE muab txhua yam sib txawv thiab ntsuas ntawm flanges. Tiv tauj pebmarket@htpipe.comkom paub ntau ntxiv thiab ib daim ntawv tsocai dawb!
Raised Face vs Ring Type Joint: Yam twg rau Chav Kawm 1500?
Qhov no yog tej zaum cov lus nug uas kuv tau nug ntau zaus los ntawm cov engineers hloov los ntawm cov chav kawm qis qis rau hauv Chav Kawm 1500 thaj chaw. Ntawm chav kawm 150 thiab 300, tsa lub ntsej muag yog lub neej ntawd thiab tsis muaj leej twg xav txog ob zaug. Ntawm chav kawm 1500, qhov kev txiav txim siab muaj qhov tshwm sim.
Raised ntsej muag (RF)
Txheem tiav: 125-250 μin Ra (3.2-6.3 μm) rau kauv - qhov txhab gaskets
Ua haujlwm nrog kauv- qhov txhab, Kammprofile, ob npaug -jacketed, thiab daim ntawv gaskets
Yooj yim rau nruab thiab hloov gaskets hauv qhov chaw
Tsawg flange nqi (tsis muaj zawj machining)
Kev txwv ntawm Chav Kawm 1500:Gasket blowout kev pheej hmoo nce nyob rau hauv loj diameters thiab siab kub. ASME B16.20 yuav tsum muaj lub nplhaib sab hauv ntawm kauv- qhov txhab gaskets rau Chav Kawm 900 thiab siab dua.
Haum rau: chav dej, dej, hydrocarbons hauv qab nws pib- qhov kub thiab txias, txheej txheem dav dav
Lub nplhaib hom Joint (RTJ)
Siv lub nplhaib hlau khoom (oval lossis octagonal cross-section) zaum hauv machined grooves
Hlau-rau- hlau foob; lub nplhaib deforms plastically nyob rau hauv bolt load
Lub nplhaib yog ib qho - siv. Tshem lub flange thiab koj hloov lub nplhaib. Tsis muaj kev zam.
Tus nqi siab dua flange (precision groove machining yuav tsum tau)
RTJ grooves yuav tsum tau kuaj xyuas kev puas tsuaj ua ntej txhua qhov sib dhos. Ib tug scratched zawj lub ntsej muag yuav xau.
Standard ntawm Class 1500 rau:Kev pabcuam Hydrogen, kua tshuaj lom (ASME B31.3 Qeb M), kev pabcuam roj siab tshaj 600℃F, kev sib txuas ntawm lub taub hau rau API 6A
Flange Installation txheej txheem
Tshawb xyuas qhov chaw zaum
Tshawb xyuas lub ntsej muag phonographic serrations los yog RTJ txoj kab groove yog tsis muaj gouges, cuab yeej cim, los yog radial khawb. Txhua txoj hauv kev hla lub ntsej muag yuav dhau los ua qhov siab - txoj kev xau siab.
Teem thiab Insert Gasket
Nruab nrab ntawm - siab gasket (feem ntau yog ib tug kauv- qhov txhab hlau gasket nrog lub nplhaib sab hauv los yog ib lub nplhaib hlau RTJ octagonal). Tsis txhob rov qab siv lub compressed gasket.
Lubricate Studs
Siv cov npib tsib xee-raws li kev tiv thaiv- txeeb cov khoom sib xyaw ua ke rau cov hlua khi thiab cov txiv ntseej ntsej muag. Qhov no ua kom muaj kev sib txhuam tsis sib xws thaum siv lub zog torque.
Torque nyob rau hauv Progressive theem
Hla-tighten cov txiv ntseej siv lub hnub qub qauv lossis hydraulic tensioners. Ua kom tiav tag nrho torque incrementally:
Theem 1:Tighten rau 30% ntawm lub hom phiaj tus nqi.
Theem 2:Tighten rau 60% ntawm lub hom phiaj tus nqi.
Kauj Ruam 3:Tighten rau 100% ntawm lub hom phiaj tus nqi.
Final Pass:Ua ib qho kev sib hloov clockwise cheb ntawm 100% torque los xyuas kom meej qhov sib npaug ntawm txhua txoj haujlwm bolting.
