Kev faib khoom
Square tube (ntsuab, daj)
Cov raj tooj liab feem ntau tuaj yeem muab faib ua hom hauv qab no:
Copper condenser tubes, crystallizer tooj liab raj, cua txias tooj liab tubes, ntau yam extruded, kos (rov qab extruded) tooj liab tubes, hlau dawb tooj liab tubes, tooj dag tubes, bronze hlab, dawb tooj liab tubes, beryllium tooj liab tubes, tungsten tooj liab tubes, , aluminium bronze hlab, tin bronze hlab, imported liab tooj liab raj, thiab lwm yam.
Nyias-walled tooj liab raj, capillary tooj liab raj, kho vajtse tooj liab raj, tshwj xeeb zoo li tus tooj liab raj, me me tooj liab raj, cwj mem tooj liab raj, cwj mem tooj liab raj, thiab lwm yam.
Raws li cov neeg siv xav tau, square thiab rectangular crystallizer tooj liab raj, D-hom tooj liab raj, eccentric tooj liab raj, thiab lwm yam yog ua tiav thiab ua raws li cov duab kos.
Tus nqi khoom
Cov kav dej tooj liab puas kim dhau? Ntau cov yeeb nkab fittings ntawm kev ua lag luam tsis pheej yig dua li cov yeeb nkab tooj liab fittings. Nws puas raug nqi siv cov kav dej tooj liab? Qhov tseeb, qhov zoo ntawm cov yeeb nkab tooj liab fittings lawv tus kheej thiab cov txiaj ntsig kev lag luam uas lawv coj tuaj yeem ua tiav rau lossis txawm tias tshaj tus nqi siab ntawm cov khoom siv raw. Ntawm ntau yam yeeb nkab fittings, qhov kev ua tau zoo-nqi piv ntawm tooj liab yeeb nkab fittings yog qhov thib ob. Qhov kev ua tau zoo ntawm cov kua hauv cov kav dej tooj liab yog qhov zoo dua li ntawm lwm cov kav dej, tsis muaj kev tiv thaiv tsawg, thiab nws tsis yooj yim ua rau cov dej tsis zoo los yog txawm tias thaiv; nyob rau tib lub ndlwg tus nqi, cov kav dej tooj liab muaj qhov me me hauv txoj kab uas hla thiab cov phab ntsa nyias dua li lwm cov kav dej, uas txo cov dej ntws mus rau qhov tsawg kawg nkaus. Yog li ntawd, cov kav dej tooj liab tuaj yeem siv tsis tau tsuas yog siv cov kav dej me me nyias-walled tooj liab kom txuag tau cov ntaub ntawv, tab sis kuj txuag tau ntau lub zog siv. Cia peb ua lwm qhov kev suav: yog tias tsuas yog los ntawm thawj qhov peev, tus nqi kom zoo dua ntawm cov khoom siv tooj liab tsis pom tseeb. Piv txwv li, thawj zaug peev ntawm cov kav dej tooj liab yog 2.5 npaug ntawm cov kav dej galvanized. Tab sis qhov kev pab cuam lub neej yav dhau los yog tsawg kawg yog 3-4 npaug ntawm qhov kawg. Yog tias peb ntxiv cov nqi txuag ntawm cov yeeb nkab tooj liab fittings, xws li qhov tseeb tias tooj liab yeeb nkab fittings siv cov ntaub ntawv tsawg dua li lwm cov yeeb nkab fittings, yog ib qho yooj yim rau nruab thiab tsis tas yuav tsum tau tu, muaj kev saib xyuas zoo, ruaj khov thiab tsis muaj kuab paug ib puag ncig, thiab lwm yam, qhov zoo ntawm tooj liab dej cua sov tshuab yog qhov zoo thiab tus nqi qis. Nyob rau hauv cov ntaub ntawv ntawm cov dej kub, nrog lub zog txuag kom zoo dua tooj liab, qhov sib txawv ntawm nws thiab cov kav dej dav dav thiab cov kav dej tooj liab tseem ceeb dua. Rau cov neeg yuav khoom hauv tsev, noj qhov kho kom zoo nkauj ntawm ob chav pw thiab ib chav tsev nyob hauv Shanghai ua piv txwv, tag nrho cov kav dej kub thiab dej txias yog ua los ntawm cov kav dej tooj liab, thiab tus nqi tsuas yog kwv yees li ib txhiab yuan. Rau ib lub tsev muaj nqis ntau pua txhiab yuan thiab tus nqi kho kom zoo nkauj ntawm kaum tawm txhiab yuan, qhov kev siv nyiaj ntxiv tsis yog loj, tab sis nws tsim nyog tag nrho. Tsis tas li ntawd, kev txhim kho cov kav dej tooj liab thiab fittings hauv ib lub tsev yog sib npaug rau kev nqis peev ntawm cov nyiaj hauv kev txuag nyiaj. Vim tias ntau xyoo tom qab, thaum lub tsev puas lawm thiab tag nrho lwm yam khoom siv thiab cov khoom siv tsis muaj txiaj ntsig, cov yeeb nkab tooj liab tseem tuaj yeem yooj yim disassembled thiab rov ua dua raws li qhov xav tau, thiab txawm tias muag cov kav dej tuaj yeem tau txais ntau dua.
