ASME SA516-Pressure Vessel Steel (PVQ) Phaj
ASME SA516 (ASTM A516) yog ib qho kev qhia tshwj xeeb rau cov pa roj carbon steel phaj siv hauv cov hlab ntsha siab thiab boilers rau nruab nrab - qhov kub thiab nruab nrab - qhov chaw tsis tshua muaj siab. Cov qib sib txawv ntawm SA516 (piv txwv li, Qib 55,60,65,70) sib txawv nyob rau hauv lawv cov kev xav tau tshuaj lom neeg thiab Tensile Requirements, uas txiav txim siab lawv tsim nyog rau cov kev siv tshwj xeeb.Qhov feem ntau siv ntawm cov no yog Gr.70.
Qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm cov qib sib txawv txiav txim siab lawv cov kev siv tshwj xeeb:
gr55 ua: Cov ntsiab lus carbon tsawg (tsawg dua lossis sib npaug li 0.27%), cov ntsiab lus manganese nruab nrab (0.85 ~ 1.20%), weldability zoo thiab qis- kub toughness (-45℃cuam tshuam kev kuaj xaiv). Lub zog tensile yog 380 ~ 515 MPa thiab lub zog tawm los yog ntau dua lossis sib npaug rau 205 MPa.
Tsawg-kub siab cov hlab ntsha: xws li liquefied natural gas (LNG) cia tso tsheb hlau luam, kua nitrogen / kua oxygen ntim, thiab lwm yam., haum rau ib puag ncig saum toj no -45℃.
Tsawg- cov hlab ntsha siab: atmospheric siab cia tso tsheb hlau luam, cov tshuaj tiv thaiv kettles, kub exchanger plhaub, thiab lwm yam.
Petrochemical khoom: desulfurization ntauwd, distillation ntauwd, thiab lwm yam scenarios nrog tsawg corrosive yuav tsum tau.
Boiler Cheebtsam: qis-siab boiler ladle, header, thiab lwm yam.
gr 60Cov ntsiab lus siab dua me ntsis (tsawg dua lossis sib npaug li 0.30%), siab manganese cov ntsiab lus (0.85 ~ 1.50%), tensile lub zog ntawm 415 ~ 550 MPa, yield zog ntau dua los yog sib npaug rau 220 MPa. zoo sib npaug ntawm lub zog thiab toughness.
Cov hlab ntsha nruab nrab siab: cov khoom sib cais, cov tank tsis muaj, thiab lwm yam hauv cov roj av refining.
Cov cuab yeej siv tshuaj: ammonia synthesis ntauwd, urea reactor thiab lwm lub sijhawm xav tau lub zog nruab nrab.
Kev lag luam fais fab: boiler ladle, superheater plhaub (ua haujlwm kub tsawg dua lossis sib npaug li 350 degree).
Shipbuilding: theem nrab siab- bearing qhov chaw ntawm liquefied gas carriers.
gr65 ua: Ntxiv rau cov ntsiab lus carbon thiab manganese (C Tsawg dua lossis sib npaug li 0.31%, Mn Tsawg dua lossis sib npaug li 1.60%), tensile zog 450 ~ 585 MPa, yield zog ntau dua lossis sib npaug rau 240 MPa. Lub zog siab dua, tab sis qhov vuam yuav tsum tau preheated (piv txwv li, 150℃lossis ntau dua).
Siab - lub nkoj siab: ammonia reactor, hydrogenation reactor thiab lwm yam khoom siv raug siab.
Cov khoom siv hluav taws xob: siab- kub thiab siab- qhov chaw siab ntawm lub chaw nres tsheb fais fab boilers (yuav tsum tau siv nrog cov txheej txheem cua sov).
Hnyav- lub tank tso dej: lub nplhaib los yog cov phaj saum toj kawg nkaus ntawm cov roj av loj.
Tsawg-kev siv kub: -60℃qhov yuav tsum tau muaj kev cuam tshuam tuaj yeem ua tau los ntawm kev kho kom zoo, siv rau cov khoom siv polar.
gr 70:.Qib siab zog siab tshaj (lub zog tensile 485 ~ 620 MPa, yield zog ntau dua los yog sib npaug rau 260 MPa), tab sis plasticity thiab weldability kuj txo, yuav tsum tau nruj tswj cov txheej txheem vuam.
Kev kub siab ib puag ncig: siab siab roj cia tso tsheb hlau luam (xws li CNG tso tsheb hlau luam), auxiliary siab hlab ntsha rau nuclear fais fab nroj tsuag.
Hnyav-cov qauv ua haujlwm: txhawb nqa thav duab lossis siab- lub plhaub muaj zog rau cov khoom siv tshuaj loj.
Cov ntawv thov tshwj xeeb: cov hlab ntsha ntawm lub xov tooj ntawm tes (xws li lub tsheb thauj khoom) qhov twg yuav tsum tau txo qhov hnyav, thinning ntawm phab ntsa thickness los ntawm lub zog siab.
