Qhov zoo ntawm stainless hlau welded yeeb nkab ntau lawm: Ua ntej ntawm tag nrho cov, nyob rau hauv cov txheej txheem ntawm stainless hlau welded yeeb nkab, cov yeeb nkab lub cev yuav sib npaug zos, thiab ces tom qab hauv internet ci khoom melting annealing, nto yuav du heev, thiab tus du nto yog. tsis yooj yim rau scale, nrog anti-scaling nta.Qhov no yog ob qho tib si rau cov cua kub dissipation thiab tsis tas yuav tsum tau ntxuav tas li, txuag lub sijhawm, kev siv zog thiab nyiaj txiag.Qhov thib ob, cov yeeb nkab welded yog cov khoom sib sib zog nqus ntawm cov phaj, thiab nws qhov zoo ntawm cov phab ntsa tuab yog qhov tsis sib xws.Nyob rau tib lub sijhawm, nws tuaj yeem ua qhov loj me, nrog qhov raug siab.Thirdly, cov khoom siv stainless hlau muaj cov yam ntxwv ntawm kev tiv thaiv corrosion thiab kev pab lub neej ntev.

Cov xwm txheej tam sim no ntawm stainless hlau welded yeeb nkab khoom: Lub peev xwm ntawm Tuam Tshoj txoj kev lag luam stainless hlau welded yeeb nkab tsis phim cov kev lag luam hauv tsev.Feem ntau ntawm cov uas twb muaj lawm stainless hlau welded yeeb nkab chav tsev cov txheej txheem cov cuab yeej ua tsis tiav, xws li tsis muaj kev kho cua sov thiab cov khoom siv kuaj hauv online, kom lub peev xwm ntau lawm ntawm chav tsev muab kev ua si tag nrho, feem ntau tsuas tuaj yeem tsim cov khoom siv kho kom zoo nkauj, thiab kev ua lag luam ntawm nruab nrab thiab qis-qib stainless hlau hniav welded hlab tshaj qhov khoom;Cov txheej txheem siab dua muaj welded raj, xws li cov tshuab siv tshuaj lom neeg thiab cov khoom siv hluav taws xob, tsuas yog ob peb lub tuam txhab tuaj yeem tsim tau, tab sis lub peev xwm ntau lawm tsis txaus.Hangao Tech (SEKO Machinery) SZG-JM series precision stainless hlau welded yeeb nkab ntau lawm kab daws qhov teeb meem no.Tag nrho cov kab ntau lawm suav nrog cov txheej txheem xws li tsim vuam, sab hauv vuam seam leveling, vuam seam sib tsoo, ci annealing, thiab sizing txiav.Lub tshuab hluav taws xob ntse tswj kev tswj xyuas kev ua haujlwm ntawm txhua qhov, txhim kho kev ua haujlwm thaum txo kev siv hluav taws xob.
Cov yeeb nkab welded puas tuaj yeem ua rau cov khoom siv hluav taws xob sib pauv?
1. Cov khoom siv siab dua cov raj muaj peev xwm ua tau
Lub tshav kub exchanger tube yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob thiab cov raj xa hluav taws xob, thiab cov raj xa hluav taws xob feem ntau yog xaiv raws li qhov siab thiab cov kua nruab nrab.Tam sim no ib qho kev nkag siab tsis zoo hauv kev xaiv cov raj xa hluav taws xob hauv kev lag luam yog cov hlau tsis muaj steel hlau tsis tuaj yeem siv los ua cov raj xa hluav taws xob, tab sis GB / 151-1999 qhia meej meej tias cov hlau tsis muaj steel welded raj tuaj yeem xaiv tau thaum lub raj sab siab. yog ≤6.4MPa.Tshwj xeeb tshaj yog tam sim no hais tias cov txheej txheem ntawm stainless hlau welded kav yog tam sim no paub tab, nws muaj peev xwm ua tau raws li cov kev xav tau ntawm cov cua kub exchanger tubes, thiab qhia nws tshwj xeeb zoo.
2. Cov txheej txheem ntau lawm yog mature, austenitic stainless hlau welded yeeb nkab yuav yog thawj qhov kev xaiv
Txij li thaum lub tshav kub exchanger raj tsim lub tshav kub hloov chaw ntawm lub tshav kub exchanger, qhov loj ntawm lub tshav kub exchanger raj muaj ib tug zoo ntxim rau lub tshav kub hloov.Thaum siv cov raj me me, qhov chaw sib pauv cua sov hauv ib chav tsev ntawm cov khoom siv hluav taws xob sib txawv loj dua, cov cuab yeej siv tau zoo, cov hlau siv rau ib chav tsev kub hloov chaw yog tsawg dua, thiab cov cua sov hloov coefficient kuj siab dua.Txawm hais tias nws muaj teeb meem rau kev tsim khoom, kev siv cov austenitic stainless hlau welded raj raws li cov raj xa hluav taws xob tuaj yeem zam cov teeb meem saum toj no.Vim hais tias austenitic stainless hlau welded raj muaj qhov zoo corrosion kuj thiab du nto, thiab cov txheej txheem ntau lawm yog paub tab, yog li austenitic Stainless hlau welded hlab yog thawj xaiv rau tshav kub exchanger raj.Cov ntaub ntawv uas tuaj yeem ua tiav los ntawm Hangao Tech (SEKO Machinery) SZG-JM series welded yeeb nkab ntau lawm kab muaj xws li: stainless hlau, austenite, ferrite, titanium alloy thiab dual theem hlau, uas muaj ntau yam ntau yam thiab tuaj yeem tsim thiab kho raws li cov neeg siv khoom xaj.
