Kev siv ntau yam ntawm stainless hlau fittings, carbon steel fittings, thiab alloy steel fittings
1: Carbon steel fittings (20 #, Q235, ASTM A234 WPB thiab lwm yam)
Cov yam ntxwv ntawm cov khoom
Tus nqi tshaj - siv tau, lub zog nruab nrab, yooj yim rau vuam thiab txheej txheem, tsis tiv taus corrosion, kub kub, yooj yim rau xeb, nyiam rau qhov kub thiab txias siv.
lub hom phiaj tseem ceeb
Kev xa dej thiab kev tso dej, kev tsim vaj tsev hauv nroog: cov kav dej xa dej, cov kav dej kav dej zoo tib yam, cov kav dej cua sov thiab cov kav dej loj, cov kav dej tsis tshua muaj siab - kis tau tus mob.
Cov kua dej dav dav: compressed cua ntawm chav tsev kub, dej txias, cov khoom siv roj zoo tib yam, thiab kev thauj mus los ntawm cov xov xwm tsis muaj corrosive.
Txhawb nqa cov qauv hlau rau cov tsev, qis- cov kav dej siab rau cov tshuab tua hluav taws, thiab cov dej ntws mus rau cov tsev tsim khoom.
Nruab nrab thiab tsis tshua muaj siab thermal pipeline network (kub Tsawg dua los yog sib npaug li 350 degree), fais fab nroj tsuag auxiliary cooling water pipeline.
Kev txwv: Tsis tuaj yeem siv nyob rau hauv acidic, alkaline, seawater, thiab kub kub.
2: Stainless hlau fittings (304, 316L, 321)
Cov yam ntxwv ntawm cov khoom
Acid thiab alkali corrosion kuj, tiv thaiv xeb, siab huv, zoo dua -kub tsis kam tshaj carbon steel, thiab tus nqi siab.
lub hom phiaj tseem ceeb
Khoom noj khoom haus thiab tshuaj kev lag luam: dej haus, brewing, tshuaj purified dej, kev thauj mus los ntawm mis nyuj (feem ntau sanitary qib yeeb nkab fittings).
Tshuaj tiv thaiv corrosion: qaug zog acid thiab tsis muaj zog alkali, ntsev tov, dej hiav txwv, dej phwj desulfurization pipeline; 316L yog resistant rau chloride ions thiab feem ntau yog siv nyob rau hauv seawater thiab tshuaj khib nyiab kua.
Cov dej ntshiab huv, siab - cov pa roj purity: Lub Hoobkas hluav taws xob cov dej ntshiab huv, nitrogen / oxygen cov kav dej huv.
Chav ua noj thiab chav dej, cov dej haus hauv nroog, cov dej kub kub, boiler siab -cov kav dej kub.
Petrochemical lub teeb roj cov khoom lag luam thiab cov khoom siv tshuaj zoo hauv cov kav dej.
304: Pa tsis muaj zog acid, dej haus; 316L: dej hiav txwv, chloride ion ib puag ncig, muaj zog corrosive nruab nrab.
3: Alloy steel yeeb nkab fittings (16Mn, 12Cr1MoV, P91 / P92, 15CrMo thiab lwm yam chromium molybdenum alloys)
Cov yam ntxwv ntawm cov khoom
Kev kub siab ua haujlwm, kev kub siab ua haujlwm, kev ua haujlwm siab, kev ua haujlwm siab, zoo heev -kub lub zog, ib feem ntawm cov cua sov- tiv taus thiab hydrogen resistant, nrog tus nqi siab tshaj.
Lub hom phiaj tseem ceeb (tshwj xeeb rau qhov kub thiab txias)
Thermal power/thermoelectric boiler: boiler water-cooled wall, superheater, main steam pipeline (high temperature and high pressure above 500 degree, nquag siv 12Cr1MoV, P91).
Petrochemical refining unit: hydrogenation unit, cracking furnace, high -kub hnyav roj pipeline, inlet thiab qhov hluav taws xob ntawm hydrogenation reactor (nyob rau hauv qhov kub thiab txias ib puag ncig nyob ze hydrogen).
Coal tshuaj thiab chiv cov nroj tsuag: hluavtaws ammonia siab - cov kav dej siab, siab - cov kav dej kub txheej txheem.
Kev kub siab hydraulic, siab - siab roj: siab - siab hydrogen, siab - siab chav, siab - siab boiler lub ntsiab pipeline.
16Mn (Q345): Tsawg kub nruab nrab thiab cov hlab ntsha siab siab, qis- cov kav dej kub txheej txheem; Chromium molybdenum steel: Kub kub thiab siab siab petrochemical, fais fab nroj tsuag tub ntxhais kav.
