HT PIPE muab txhua yam sib txawv thiab ntsuas ntawm flanges. Thov koj txhob xav li castiv tauj pebrau cov lus qhia ntxiv txog cov khoom thiab tus nqi.
Threaded flanges (tseem hu ua tus khub flanges lossis screwed flanges) yog dhuav kom phim lub taub sab hauv ntawm cov yeeb nkab, tab sis muaj cov yam ntxwv sab hauv.NPT (National yeeb nkab xov)threads ua raws li ASME B1.20.1.
Chav Kawm 900 siab ntsuas yog qhov kev faib tawm lub zog. Nws txhais tau hais tias lub siab ua haujlwm siab uas muaj peev xwm tuav tau ib puag ncig siab tshaj 2250 psi (kwv yees li 155 bar) ntawm qhov kub thiab txias, nyob ntawm qhov metallurgy (xws li ASTM A105 carbon steel piv rau ASTM A182 stainless hlau).
Vim li cas Threaded ntawm 900lb Rating?
Nyob rau hauv feem ntau piping designs, raws li kev ntsuas siab nce, vuam yuav tsum tau. Txawm li cas los xij, Chav Kawm 900 threaded flange yog siv tswv yim nyob qhov twg:
Tshaj tawm -Kev kho cua sov (PWHT) yog qhov tsis zoo:Hauv cov chaw ua haujlwm lossis thaj chaw nyob deb qhov chaw ua haujlwm - vuam thiab kev ntxhov siab tom qab - txo cov kev kho cua sov yog logistically tsis yooj yim sua.
Explosive/Hazardous Atmospheres Muaj:Kev tu ib puag ncig uas qhib nplaim taws lossis vuam arcs ua rau muaj kev pheej hmoo ntawm hluav taws kub tam sim ntawd.
Cov ntaub ntawv sib txawv yuav tsum tau koom nrog:Daim ntawv thov qhov kev hloov pauv ntawm kev nyab xeeb, un{0}}weldable alloys lossis hardened Cheebtsam yog tsim nyog.
Xov Engagement Mechanics
Siv tau xov Length:Qhov tob ntawm cov xov sab hauv yuav tsum ua kom muaj kev sib koom ua ke nrog cov yeeb nkab sab nraud kom ntseeg tau tias kev sib khi.
Sealant Equation:Vim NPT threads cia siab rau cov hlau-rau-hlau wedging raws crests thiab cov hauv paus hniav, siab - siab 900lb daim ntaub ntawv feem ntau yuav tsum tau tshwj xeeb anaerobic xov sealants los yog structural sealing welds (seal welding) ua rau sab nraud daim di ncauj, piv txwv li ib puag ncig tso cai rau nws.
Cov txheej txheem xaiv cov khoom siv rau siab - Ib puag ncig siab
Qhov loj me uas tau teev saum toj no tseem zoo ib yam txawm hais tias siv cov khoom siv, tab sis lub siab -lub hnab ntawv kub sib txawv heev. Xaiv cov khoom siv qib zoo kom ntseeg tau tias lub flange tuaj yeem ua raws li kev xav tau ntawm Chav Kawm 900 kev pabcuam.
ASTM A105 (Forged carbon hlau):Cov khoom siv ua ntej rau ambient rau siab -kub roj, roj, thiab hydrocarbon ua kab.
ASTM A182 (F316 / F316L Stainless hlau):Xaiv rau siab - ib puag ncig corrosion los yog qis -kub cryogenic daim ntaub ntawv. Lub zog qis zog ntawm stainless hlau ntawm qhov kub siab yuav tsum ceev faj siab de- ntsuas.
ASTM A350 LF2 (Tsawg-Temp Carbon Steel):Qhov tseem ceeb rau tej yaam num nyob rau hauv cheeb tsam cheeb tsam uas muaj huab sub-zero winters (xws li Canadian roj sands los yog Siberian thauj kab).
