Welded Nickel Alloy Steel Yeeb Tube

Cov khoom siv muaj pes tsawg leeg thiab cov khoom

Nickel Alloy Steel yog qhov sib xyaw sib xyaw ntawm cov npib tsib xee nrog lwm cov ntsiab xws li chromium, molybdenum, hlau, thiab qee zaum copalal, tooj liab, lossis titanium. Nickel nws tus kheej tau muab kev tiv thaiv zoo heev rau kev xeb, tshwj xeeb tshaj yog hauv kev txo qhov chaw ib puag ncig, thiab muab siab dua - qhov kub kom ruaj khov. Raws qhov ntxiv txhim kho kev txhim kho corrosion tsis kam los ntawm kev tsim cov roj oxide passive nyob rau saum npoo, tiv thaiv cov hlau los ntawm oxidation thiab ntau yam kev tawm tsam. Molybdenum boosts tsis kam rau pitting thiab crevice corrosion, tshwj xeeb hauv chloride - muaj tshaj tawm.

Cov alloys nthuav qhia cov khoom siv zoo, tswj kom muaj zog siab thiab duction txawm tias thaum nce kub. Piv txwv li, qee tus npib tsib xee - chromium almoys tuaj yeem khaws lub peev xwm tseem ceeb txog 1100 degree (2012 DEGREE), ua rau lawv haum rau cov khoom siv hlau yuav ua rau cov neeg hlau ib txwm yuav degrade sai. Lawv lub peev xwm tiv thaiv kev ntxhov siab - corrosion cracking, ib qho tshwm sim uas cov ntaub ntawv uas muaj kev ntxhov siab nyob rau hauv kev sib xyaw ua ke hauv kev ua haujlwm hnyav hauv kev ua haujlwm hnyav.

Cov txheej txheem tsim khoom

Kev tsim cov welded noickel alloy steel yeeb nkab leeg pib nrog xaiv kom tsim nyog Nickel cov phiaj los yog ib daim hlab. Cov ntaub ntawv raw no yog - txiav rau qhov yuav tsum tau qhov ntev raws li qhov xav tau yeeb nkab loj, ntev, thiab phab ntsa thickness. Cov txheej txheem tshaj tawm feem ntau yuav cuam tshuam nrog yob - sib sau lossis xovxwm - braking, qhov twg cov hlau yog khoov rau hauv ib lub cylindrical puab.

Thaum tsim tau, cov npoo tau koom nrog siv cov txheej txheem vuam siab. Tungsten inert roj (tsov) vuam feem ntau ua haujlwm rau nws qhov tseeb thiab muaj peev xwm tsim cov khoom lag luam siab - cov ntaub ntawv huv nrog tsawg. Hom no zoo tagnrho rau thinner - walled kav thiab cov ntawv thov uas yog sab hauv du thiab sab nraud ua tiav yog qhov tseem ceeb. Rau thicker kav - walled kav lossis siab dua - ntim ntau lawm, submerged arc vuam (pom) yuav siv. Shag muab cov kev sib tw nrawm dua thiab tob rau nkag siab, ua kom muaj zog thiab txhim khu kev qha pob qij txha.

Tom qab vuam, cov kav dej yaig dhau ib qho ntawm kev ntsuas tswj tau zoo. Tsis yog - txoj kev ua phem, xws li ntsuas phoo (RT) thiab ultrasonic kuaj (ut), yog siv los xyuas cov kev sib khib sab hauv lossis tsis xws luag hauv Welds. Hydrostatic Kev Ntsuam Xyuas kuj tseem ua rau txheeb xyuas lub siab - tuav lub peev xwm ntawm cov kav dej, kom lawv muaj kev nyab xeeb ua haujlwm nyob rau hauv cov kev pabcuam kev pabcuam. Ib qho ntxiv, cov txheej txheem kho kom sov yuav raug siv los ua kom muaj kev ntxhov siab sab hauv, txhim kho cov khoom siv cov khoom siv neeg kho tshuab, thiab txhim kho nws qhov kev ua tau zoo tag nrho.

Cov Ntawv Thov

Kev Lag Luam Kev Lag Luam: Welded Nickel Alloy Steel Yeeb Hmab Leeg yog qhov ntsuas kom muaj tshuaj lom neeg los thauj tshuaj, acids, alkalis, thiab cov kuab tshuaj. Lawv txoj kev tiv thaiv kom muaj ntau yam tshuaj lom neeg ua kom muaj kev ncaj ncees ntawm cov piping system, tiv thaiv kev txi thiab txo kev pheej hmoo ntawm kev paug. Piv txwv li, hauv kev tsim cov chiv, qhov twg muaj cov acids uas muaj zog thiab ammonia koom nrog, cov kav dej no tuaj yeem tiv taus ib puag ncig txoj kev tuag rau ncua sijhawm.

Lub Zog Loj: Hauv cov nroj tsuag hluav taws xob, tshwj xeeb yog cov kev siv siab siab - kub thiab siab - siab alloy steel kav yog qhov tseem ceeb. Lawv tau siv nyob rau hauv superheaters, rheaters, thiab lwm yam ntawm lub zog boiler, uas lawv yuav tsum ua kom dhau huab cua sov thiab kev sib cav yam tsis muaj kev txwv. Lawv lub siab - lub zog kub thiab lub zog ntawm cov khoom siv los deform maj mam) ua rau muaj kev ntxhov siab thiab txhim khu kev qha ntawm cov nroj tsuag fais fab.

Petrochemical thiab Roj Refining: Hauv cov roj thiab roj kev lag luam, cov kav dej no tau ua haujlwm rau kev tuav cov khoom ua kom zoo nkauj, nrog rau hauv cov roj pob hluav taws xob txhawm rau thauj cov roj crude thiab roj. Lawv tuaj yeem tawm tsam cov teebmeem corrosive ntawm qaub gases (muaj hydrogen sulfide) thiab ntsev, uas muaj ntau nyob rau hauv cov chaw no. Lawv lub peev xwm tiv taus siab - cov xwm txheej siab yog qhov tseem ceeb rau kev nyab xeeb thiab kev thauj khoom zoo ntawm kev ncua ntev.

Aerospace thiab High - Tech Industries: Welded Nickel Alloy Steel Yeeb Hmab Leeg Nrhiav cov ntawv thov hauv kev tsim khoom hauv Aerospace, uas lawv tau siv rau hauv cov tshuab hluav taws xob thiab cov tshuab roj. Cov kev ua haujlwm dhau los hauv tshuab, suav nrog kev ntsuas siab, siab siab, thiab nthuav tawm cov khoom sib txuas, xav tau cov ntaub ntawv nrog cov yam ntxwv tshwj xeeb. Nickel alloys tau raws li cov kev xav tau, muab cov khoom tsim nyog, durability, thiab corrosion, kom muaj kev ntseeg tau thiab kev nyab xeeb ntawm kev tiv thaiv thiab kev nyab xeeb ntawm kev tiv thaiv thiab kev nyab xeeb ntawm lub tshuab hluav taws xob.
