Seamless steel yeeb nkab muaj qhov zoo ntawm cov khoom zoo thiab lub zog siab.
Nws cov khoom muaj carbon steel, zoo hlau, tsis tshua muaj hlau alloy, stainless hlau, kub-resistant steel.Vim muaj ntau txoj kev tsim khoom, nws tau muab faib ua ob hom kub dov seamless steel yeeb nkab thiab txias-draw seamless steel yeeb nkab.Pipeline engineering yeeb nkab txoj kab uas hla ntawm ntau tshaj 57 hli, feem ntau siv cov yeeb nkab kub dov, 57 hli hauv qab no feem ntau siv cov yeeb nkab txias.
Seamless steel yeeb nkab feem ntau yog siv los thauj ntau yam roj cua, vapors thiab kua, tuaj yeem tiv taus qhov kub thiab txias (txog 435 ℃).Alloy steel yeeb nkab yog siv los thauj cov xov xwm corrosive, uas cov yeeb nkab kub-resistant alloy tuaj yeem tiv taus kub txog 900-950 ℃.Seamless steel yeeb nkab specifications rau Ф puab txoj kab uas hla × phab ntsa thickness (mm).
Qhov siab tshaj plaws sab nraud ntawm cov yeeb nkab txias txias yog 200mm, thiab qhov siab tshaj plaws sab nraud ntawm cov yeeb nkab kub dov yog 630mm.Seamless steel yeeb nkab tau muab faib ua cov yeeb nkab seamless thiab tshwj xeeb seamless yeeb nkab raws li nws siv, xws li seamless yeeb nkab rau roj av tawg. , seamless yeeb nkab rau boiler, seamless yeeb nkab rau chiv thiab lwm yam.
④ Copper tube:
Copper tube muaj qhov zoo ntawm cov cua sov.
Feem ntau yog siv hauv cov khoom siv hluav taws xob sib txuas thiab cov twj tso kua dej sib sib zog nqus, ntsuas ntsuas ntsuas lub raj lossis xa cov kua dej, tab sis qhov kub thiab txias siab tshaj 250 ℃, yuav tsum tsis txhob siv nyob rau hauv siab.Vim tias kim dua, feem ntau siv rau hauv qhov chaw tseem ceeb.
⑤ Aluminium Tube:
Aluminium muaj zoo corrosion kuj.
Aluminium raj feem ntau yog siv los thauj cov concentrated sulfuric acid, acetic acid, hydrogen sulfide thiab carbon dioxide thiab lwm yam xov xwm, thiab kuj yog feem ntau siv nyob rau hauv tshav kub exchangers.Aluminium tubes tsis muaj alkali tiv taus thiab tsis tuaj yeem siv los thauj cov alkaline kev daws teeb meem thiab cov kev daws teeb meem uas muaj chloride ions.
Vim yog lub zog txhua yam ntawm txhuas raj nrog qhov kub thiab txias thiab txo qhov tseem ceeb ntawm kev siv cov raj txhuas, yog li kev siv cov raj txhuas tsis tuaj yeem tshaj 200 ℃, rau cov kav dej siab, kev siv kub yuav qis dua.Aluminium muaj cov khoom zoo dua qub ntawm qhov kub thiab txias, yog li txhuas thiab aluminium alloy raj feem ntau yog siv rau hauv cov khoom sib cais cua.
(6) Cov kav dej:
Cov yeeb nkab txhuas feem ntau yog siv los ua cov raj xa dej rau kev xa cov kua qaub tawm, tuaj yeem thauj 0.5% mus rau 15% ntawm sulfuric acid, carbon dioxide, 60% hydrofluoric acid thiab acetic acid concentration tsawg dua 80% ntawm qhov nruab nrab, yuav tsum tsis txhob thauj. mus rau nitric acid, hypochlorous acid thiab lwm yam xov xwm.Qhov siab tshaj plaws ua haujlwm kub ntawm cov yeeb nkab txhuas yog 200 ℃.
Cov raj tsis yog xim hlau
Cov yeeb nkab yas, cov yeeb nkab yas, iav yeeb nkab, cov yeeb nkab ceramic, cov yeeb nkab cement.
①Plastic yeeb nkab:
Qhov zoo ntawm cov yeeb nkab yas yog zoo corrosion kuj, lub teeb yuag, yooj yim molding, ua tau yooj yim.
Qhov tsis zoo yog qhov tsis muaj zog thiab tsis muaj cua sov ua haujlwm.
Tam sim no cov kav dej uas siv ntau tshaj plaws yog cov yeeb nkab tawv polyvinyl chloride, cov yeeb nkab muag polyvinyl chloride, cov yeeb nkab polyethylene, cov yeeb nkab polypropylene, thiab cov yeeb nkab hlau nto txau polyethylene, polytrifluoroethylene thiab lwm yam.
② roj hmab hose:
Roj hmab hose muaj corrosion kuj zoo, lub teeb yuag, zoo plasticity, installation, disassembly, saj zawg zog thiab yooj yim.
Feem ntau siv roj hmab hose feem ntau yog ua los ntawm cov roj hmab ntuj lossis hluavtaws roj hmab, tsim nyog rau lub sijhawm uas tsis tshua muaj siab.
③ Cov iav raj:
Cov iav raj muaj qhov zoo ntawm kev tiv thaiv corrosion, pob tshab, yooj yim los ntxuav, tsis muaj kev tiv thaiv, tsis tshua muaj nqi, thiab lwm yam, qhov tsis zoo yog nkig, tsis siab.
Feem ntau siv hauv kev sim lossis kev sim ua haujlwm.
④ Ceramic raj:
Chemical ceramics thiab iav zoo ib yam, zoo corrosion kuj, ntxiv rau hydrofluoric acid, fluorosilicic acid thiab muaj zog alkali, tuaj yeem tiv taus ntau yam inorganic acids, organic acids thiab organic solvents.
Vim tsis muaj zog, nkig, feem ntau yog siv los tshem tawm corrosive xov xwm lim dej thiab cov kav dej tso cua.

4 Hom Fittings
Ntxiv rau cov yeeb nkab hauv cov raj xa dej, txhawm rau ua kom tau raws li cov kev xav tau ntawm cov txheej txheem tsim khoom thiab kev teeb tsa thiab kev saib xyuas, muaj ntau lwm yam hauv cov raj xa dej, xws li cov raj luv luv, lub luj tshib, tees, reducers, flanges, blinds thiab lwm yam.
Peb feem ntau hu cov khoom no rau cov kav dej txuas ntxiv hu ua fittings.Cov yeeb nkab fittings yog qhov tseem ceeb ntawm cov kav dej.Ntawm no yog ib qho kev qhia luv luv rau ntau qhov kev siv fittings.
① Lub luj tshib
Luj tshib feem ntau yog siv los hloov cov kev taw qhia ntawm cov kav dej, raws li lub luj tshib dabtsi yog khoov degree ntawm kev faib tawm sib txawv, feem ntau 90 °, 45 °, 180 °, 360 ° luj tshib.180 °, 360 ° luj tshib, tseem hu ua "U" zoo li khoov.
Tseem muaj cov txheej txheem piping xav tau ib lub kaum ntse ntse ntawm lub luj tshib.Lub luj tshib yuav siv tau ncaj yeeb nkab dabtsi yog khoov los yog yeeb nkab vuam thiab ua tau, kuj yuav siv tau tom qab molding thiab vuam, los yog casting thiab forging thiab lwm txoj kev, xws li nyob rau hauv high-pressure pipeline luj tshib yog feem ntau high-zoo carbon steel los yog alloy steel forging. thiab ua.
② Ib
Thaum ob lub raj xa dej txuas rau ib leeg lossis xav tau kom muaj kev hla dhau, qhov haum ntawm qhov sib koom ua ke hu ua tee.
Raws li qhov sib txawv ntawm kev nkag mus rau cov yeeb nkab, muaj ntsug nkag mus rau qhov zoo sib txuas tee, kab pheeb ces kaum txuas tee.Slanting tee raws li lub kaum sab xis ntawm slanting los teeb lub npe, xws li 45 ° slanting tee thiab lwm yam.
Tsis tas li ntawd, raws li qhov loj ntawm lub caliber ntawm lub inlet thiab qhov hluav taws xob feem, xws li sib npaug txoj kab uas hla tee.Ntxiv nrog rau cov tee fittings ntau, tab sis kuj feem ntau nrog cov naj npawb ntawm cov interfaces hu ua, piv txwv li, plaub, tsib, kab pheeb ces kaum txuas tee.Common tee fittings, ntxiv rau cov yeeb nkab vuam, muaj cov pwm pwm vuam, casting thiab forging.
③Nipple thiab reducer
Thaum lub raj xa dej sib dhos hauv qhov tsis txaus ntawm ib feem me me, lossis vim yog kev saib xyuas xav tau hauv cov kav dej los teeb tsa ib ntu me me ntawm cov yeeb nkab tshem tau, feem ntau siv lub Nipple.
Lub txiv mis takeover nrog connectors (xws li flange, ntsia hlau, thiab lwm yam), los yog tsuas yog ib tug luv luv raj, kuj hu ua cov yeeb nkab gasket.
Yuav yog ob txoj kab uas hla tsis sib xws ntawm lub qhov ncauj txuas nrog cov yeeb nkab fittings hu ua reducer.Feem ntau hu ua lub taub hau loj.Xws li fittings muaj casting reducer, tab sis kuj nrog cov yeeb nkab txiav thiab welded los yog welded nrog steel phaj dov rau hauv.Reducers nyob rau hauv high-pressure pipelines yog tsim los ntawm forgings los yog shrunken los ntawm high-pressure seamless steel raj.
④ Flanges thiab blinds
Txhawm rau txhim kho kev txhim kho thiab kev saib xyuas, cov raj xa dej feem ntau yog siv rau hauv kev sib txuas, flange yog ib qho kev sib txuas feem ntau siv.
Rau kev ntxuav thiab tshuaj xyuas yuav tsum tau teeb tsa hauv lub kav dej ntawm tes qhov qhov muag tsis pom lossis qhov muag tsis pom lub phaj ntsia ntawm qhov kawg ntawm cov yeeb nkab.Qhov muag tsis pom phaj kuj tseem siv tau los kaw ib ntus ntawm cov kav dej ntawm qhov sib txuas lossis ib ntu ntawm cov kav dej kom cuam tshuam kev sib txuas nrog lub kaw lus.
Feem ntau, cov kav dej tsis tshua muaj siab, cov duab ntawm qhov muag tsis pom thiab cov khoom flange zoo ib yam, yog li qhov muag tsis pom no tseem hu ua lub flange npog, qhov muag tsis pom nrog tib lub flange tau ua qauv, qhov tshwj xeeb qhov ntev tuaj yeem pom nyob rau hauv cov ntaub ntawv tseem ceeb.
Tsis tas li ntawd, nyob rau hauv cov khoom siv tshuaj lom neeg thiab kev saib xyuas cov kav dej, txhawm rau kom muaj kev nyab xeeb, feem ntau ua los ntawm cov hlau phaj ntxig ntawm ob lub flanges ntawm cov khoom siv discs, siv los cais cov khoom siv ib ntus lossis cov kav dej thiab cov txheej txheem ntau lawm.Qhov qhov muag tsis pom no yog ib txwm hu ua insertion blind.Ntxig qhov loj ntawm qhov muag tsis pom tuaj yeem muab tso rau hauv flange sealing nto ntawm tib txoj kab uas hla.
