Welded gas cylinders yog siv dav hauv kev siab - cov pa roj cia thiab kev thauj mus los. Lawv cov kev qhia tshwj xeeb, raws li cov ntaub ntawv qhia txog kev tsim, tsim, tshuaj xyuas, thiab siv, yog lub hauv paus tseem ceeb rau kev ua kom cov khoom muaj kev nyab xeeb, kev ntseeg siab, thiab zoo ib yam. Cov kev qhia tshwj xeeb suav nrog cov kev xav tau los ntawm ntau yam kev qhuab qhia, suav nrog cov ntaub ntawv tshawb fawb, kev siv lub nkoj siab, vuam tshuab, thiab cov txheej txheem kev sim, npog tag nrho lub neej ntawm lub tog raj kheej los ntawm kev tshawb fawb thiab kev tsim kho kom pov tseg. Lawv ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib tsoo thiab txhim kho cov qauv kev lag luam.
Hais txog kev xaiv cov khoom siv, cov kev qhia tshwj xeeb qhia tau hais tias lub cev tseem ceeb ntawm cov welded gas cylinders yuav tsum tau ua los ntawm siab - zoo steel nrog zoo weldability thiab zoo sib npaug ntawm lub zog thiab toughness. Cov qib sib piv yog qis- carbon steel lossis qis- alloy steel. Nyob ntawm cov yam ntxwv ntawm qhov nruab nrab filling, stainless hlau lossis corrosion- cov ntaub ntawv tiv taus nrog kev tiv thaiv nto tuaj yeem xaiv. Cov khoom xa tuaj yuav tsum muaj daim ntawv pov thawj zoo, thiab cov qauv yuav tsum raug coj mus kuaj tshuaj lom neeg muaj pes tsawg leeg thiab kuaj cov cuab yeej cuab yeej raws li qhov yuav tsum tau ua kom ua raws li cov qauv txwv. Rau cov thooj voos kheej kheej raug corrosive lossis toxic gases, cov ntaub ntawv yuav tsum tau ua raws li kev tiv thaiv corrosion lossis kev huv huv kom txo tau qhov kev pheej hmoo ntawm cov tshuaj tiv thaiv ntawm nruab nrab thiab lub plhaub.
Tus qauv tsim yuav tsum ua raws li cov txheej txheem tsim qauv rau cov hlab ntsha siab, txiav txim siab lub tog raj kheej qhov ntsuas geometric thiab qhov tsawg kawg nkaus phab ntsa thickness raws li qhov nominal ua hauj lwm siab, ntim, thiab nruab nrab cov khoom. Lub tog raj kheej lub tog raj kheej ntawm welded gas cylinders feem ntau yog tsim los ntawm dov steel daim hlau thiab vuam longitudinal thiab circumferential seams los tsim ib tug kaw kab noj hniav, nrog stamped los yog spun kawg caps ntawm ob hnub. Specifications nthuav dav weld kev npaj, sib koom ua ke, kev hloov pauv fillets, thiab kev ntsuas kev txhawb nqa kom txo tau kev ntxhov siab thiab txhim kho lub neej qaug zog. Elliptical lossis phaj kawg lub kaus mom feem ntau yog siv, raws li lawv muab cov kev ntxhov siab ntau dua nyob rau hauv lub siab sab hauv thiab txuag cov khoom.
Welding txheej txheem tsim nyog yog ib qho tseem ceeb ntawm cov kev specifications. Ua ntej vuam, yuav tsum tau npaj cov txheej txheem vuam tshwj xeeb, txiav txim siab txoj kev vuam, txheej txheem tsis, preheating thiab interpass kub tswj, vuam consumables, thiab tom qab- kev kho cua sov yuav tsum tau. Kev ntsuam xyuas kev tsim nyog yuav tsum tau ua kom paub tseeb qhov sib xws ntawm cov khoom siv vuam thiab lub hauv paus hlau. Cov txheej txheem vuam yuav tsum nruj me ntsis ua raws li cov txheej txheem kev qhuab qhia. Rau ntau- txheej vuam, txhua txheej yuav tsum tau ntxuav thiab tshuaj xyuas. Cov welds tseem ceeb yuav tsum tau kuaj pom tam sim ntawd tom qab ua tiav, thiab tsis yog -kev kuaj kev puas tsuaj (NDT) yuav tsum tau ua qhov sib npaug. Cov txheej txheem feem ntau suav nrog kev kuaj hluav taws xob (RT), kuaj ultrasonic (UT), thiab kuaj sib nqus particle (MT). Qhov kev lees paub yog nyob ntawm lub tog raj kheej txoj kev siv thiab siab.
Tom qab kev tsim khoom, lub tog raj kheej yuav tsum tau txais kev kho cua sov tag nrho kom tshem tawm qhov seem ntawm cov vuam kev nyuaj siab thiab txhim kho nws cov qauv metallographic thiab cov khoom siv kho tshuab. Kev kuaj hydrostatic yog qhov yuav tsum tau ua kom paub tseeb tias lub tog raj kheej lub sealing thiab lub zog nyob rau hauv overpressure. Kev ntsuas siab, tuav lub sijhawm, thiab kev lees txais yuav tsum tau ua raws li cov lus qhia tshwj xeeb. Kev lees txais zaum kawg yuav tsum muaj kev ntsuam xyuas dav dav ntawm qhov tseeb ntawm qhov tseeb, qhov vuam zoo, cov txiaj ntsig kev xeem, thiab qhov chaw saum npoo. Tsuas yog tom qab dhau cov txheej txheem no tuaj yeem cim lub tog raj kheej thiab muab tso rau hauv kev siv.
Cov txheej txheem tshuaj xyuas ib ntus thaum lub sijhawm siv kuj tseem ceeb heev, suav nrog kev ntsuas phab ntsa tuab, vuam re- tshuaj xyuas, ntsuas huab cua, thiab kev ntsuas kev nyab xeeb, kom ntseeg tau tias lub tog raj kheej tsis tu ncua raws li qhov yuav tsum tau muaj kev nyab xeeb thoob plaws hauv nws lub neej. Cov kev qhia tshwj xeeb rau cov welded gas cylinders, nrog rau lawv cov kev tshawb fawb thiab kev nruj nruj, tsim kom muaj kev ruaj ntseg thaiv kev ruaj ntseg los ntawm qhov chaw mus rau qhov kawg, muab kev lav zoo rau siab - siv roj siv thoob plaws ntau yam lag luam.
