Vim li cas thiaj xaiv peb?
Peb tau koom tes los tsim peb lub tuam txhab tsim khoom tshiab, npog thaj tsam 25000 square-meter cog. Poob-foam casting tech yog siv tag nrho ntawm no, tso cov khoom siv hauv paus rau kev lag luam mus ntev.
Txoj kev casting no siv cov qauv ua npuas ncauj evaporable. Nws muab cov khoom tsim tau zoo, cov khoom tsim tau zoo thiab ua kom cov nqi tsim khoom tswj tau. Thaum pouring hlau molten, high-temperature tshav kub gasifies ua npuas ncauj qauv kiag li. Cov hlau ua kua ua rau tag nrho cov kab noj hniav thiab cov ntaub ntawv tiav castings hauv ib kauj ruam txheej txheem.
Mr. Herman tau tsom mus rau kev cob qhia cov neeg ua haujlwm hluas. Nws txhawb txhua tus neeg ua haujlwm kom kawm thiab tau txais kev tshaj lij hauv lawv cov haujlwm. Peb lub tuam txhab tsim ua tiav txoj hauv kev rau kev txhawb nqa cov neeg ua haujlwm thiab kev loj hlob ntawm kev ua haujlwm. Nyob rau hauv nws txoj kev saib xyuas, peb lub Hoobkas tsis tsuas yog hloov kho cov cuab yeej tsim khoom, tab sis kuj ua kom muaj kev vam meej ntawm cov txuj ci tshwj xeeb thiab pab pawg echelon tsev.

Cov yam ntxwv tseem ceeb
Internal thiab sab nraud threads yog machined rau standard dimension. Cov neeg ua haujlwm tuaj yeem ua tiav kev sib dhos yam tsis muaj vuam lossis cov cuab yeej hnyav hnyav. Nws haum rau cov chaw nqaim nqaim thiab cov kav dej hauv tsev kho kom zoo nkauj heev.
QT450-10 ductile hlau ua cov khoom siv hauv paus. Piv nrog rau cov pa malleable hlau fittings, nws tau zoo dua toughness thiab cov cuab yeej tiv thaiv. Brittle tawg nyob rau hauv siab load tsis tshua muaj tshwm sim.
Threads mus txog precision machining. Mating mob nyob twj ywm nruj thiab sealing kev ua tau zoo tuav ruaj khov, tiv thaiv kom muaj kev pheej hmoo ntawm cov dej thiab cov kav dej hauv cov kav dej.
Competitive Advantage
Siab Toughness dua Malleable Hlau Fittings
Nws outperforms tsoos malleable hlau qhov chaw ntawm toughness thiab siab bearing muaj peev xwm. Thaum muaj kev cuam tshuam dej-rauj tshwm sim, tawg lossis tawg tsis ua haujlwm tuaj yeem zam tau ntau.
Kev tsim kho kom ruaj khov rau cov nqi qis qis
Muaj peev xwm tiv thaiv corrosion zoo txuas ntxiv lub neej kev pabcuam, ze li ob npaug ntawm cov khoom siv galvanized zoo tib yam. Cov tswv lag luam tuaj yeem tau txais txiaj ntsig zoo dua kev lag luam mus sij hawm ntev.
Kev siv dav dav
Cov threaded fittings no nquag siv rau cov kav dej hauv tsev, cov kav dej tiv thaiv hluav taws thiab cov kav dej hauv lub Hoobkas. Lawv tau txais kev lees paub siab hauv cov haujlwm tiag tiag engineering.
Daim ntawv thov ntawm Ductile Hlau Threaded Fittings
- Cov yeeb nkab txuasCov chaw tsim kho, cov phiaj xwm kev siv hluav taws xob rau pej xeem thiab hluav taws xob tiv thaiv kab mob siv cov xov fittings rau cov yeeb nkab sib txuas ua haujlwm.
- Kev Siv DejMuaj feem xyuam rau cov khoom siv hluav taws xob thiab cov kav dej hauv nroog.
- Cov dej khib nyiab thiab dej phwj tuajHaum rau cov chaw kho dej khib nyiab thiab cov kav dej khib nyiab hauv kev lag luam.
- Kev tiv thaiv kev cuam tshuamQee cov khoom lag luam tuaj yeem ua raws li bollards rau kev tiv thaiv kev tiv thaiv.
Txoj Cai Ua Haujlwm ntawm Cov Hlau Hlau Threaded Fittings
Kev sib khi ntawm ob lub yeeb nkab yog nyob ntawm cov gaskets, lub nplhaib kawg, lub tes tsho nruab nrab thiab cov ntsia liaj qhov rooj.
- Ntxuav cov yeeb nkab kawg, xyuas kom cov chaw ruaj khov thiab tsis muaj kev puas tsuaj ua ntej kev teeb tsa.
- Mount lub nplhaib kawg, lub tes tsho nruab nrab thiab gasket tom qab kev taw qhia txog kev teeb tsa.
- Tighten bolts thiab ceev. Compression force squeezes gasket ntawm lub nplhaib kawg thiab lub tes tsho nruab nrab los tsim lub ntsej muag zoo sealing.
- Muab ob npaug rau-xyuas lub zog torque, tshuaj xyuas gasket kev ncaj ncees thiab paub meej tias xoom-xws li mob.
Ntxiv magnesium caij rau hauv cov hlau molten tsim kheej kheej graphite hais hauv cov hlau hlau. Cov khoom no tau txais txiaj ntsig zoo dua qub dua li cov hlau cam khwb cia zoo tib yam, yog li kev tawg thiab tawg qhov tshwm sim poob qis heev.
Dab tsi yog Cov Cheebtsam ntawm Cov Hlau Hlau Threaded Fittings
Xov
Txiv neej-xov los yog poj niam-xov cov qauv muaj. Lawv txuas lossis thaiv qhov kawg ntawm cov kav dej threaded.
Ductile hlau lub ntsiab lub cev
Cov ntsiab lus tseem ceeb yog hlau, carbon, silicon thiab manganese. Nws muaj zog thiab sib zog dua li niaj zaus cam khwb cia hlau, nrog lub zog tensile siab.
Mechanical joint caj pas
Ua los ntawm ductile hlau. Nws presses gasket rau hauv txoj hauj lwm raug. Bolts los yog studs khiav los ntawm caj pas los tsim compression quab yuam ntawm sealing qhov chaw.
Gasket
Cov khoom siv Elastomer feem ntau yog siv. Muab tso rau ntawm ob lub mating flange ntsej muag los tsim kev sib khi thaiv.
Dab tsi koj yuav tsum paub thaum siv Ductile Iron Threaded Fittings
Tsis txhob over-tighten. Ntau lub zog torque yuav coj stretching deformation rau ductile hlau fittings.
Siv xov sealant, lav yam tsawg kawg yog ob txoj hlua ua tiav, rau kev ruaj ntseg sealing thiab txhua yam muaj zog.
Lubricate tag nrho gasket nto nrog cov chaw tsim khoom pom zoo lubricant. Qhuav gasket yuav tsim kev sib txhuam ntxiv, ua rau poob torque thiab tom qab to taub teeb meem.
Tsis txhob siv forklift diav rawg los nqa los yog txoj hauj lwm fittings, cov ntaub ntawv saum npoo yuav raug khawb. Nyob twj ywm hauv qab cov kav dej thaum hoisting rau hauv trench.
Qhov loj, chav kawm, daim ntawv sib koom ua ke, hauv ob sab phlu, txheej thiab casting hnub tuaj yeem pom ntawm cov cim cim ze ntawm lub qhov (socket) kawg.
Ua kom pom qhov siab tshaj plaws sab nraud ua ntej siv cov xim lossis epoxy txheej sab nraud, txhawm rau suav cov txheej txheem xav tau.
Thaum Xaiv Cov Hlau Hlau Threaded Fittings
Xov engagement:siv xov sealant, ruaj ntseg yam tsawg kawg nkaus ob lub xov tag nrog rau kev sib koom ua ke.

Corrosion Resistance:ductile hlau ntaus grey cam khwb cia hlau ntawm anti-corrosion kev ua tau zoo, ntau haum rau sab nraum zoov faus installation.
Tus nqi:complex tshuaj muaj pes tsawg leeg ua rau cov nqi siab dua piv nrog cov cam khwb cia hlau zoo tib yam.
Customization muaj peev xwm:Ntsuam xyuas seb cov neeg muab khoom puas tuaj yeem tswj cov kev hloov kho uas tsis yog qauv rau koj qhov project.
System Compatibility:tshawb xyuas qhov sib piv nrog koj cov kav dej uas twb muaj lawm.
Peb lub Hoobkas
Shanxi Jintai Hongye Casting & Forging & Machinery Co., Ltd taug qab nws keeb kwm rov qab rau xyoo 1970.
Mr. Barry Khen tau koom nrog kev lag luam hauv tsev thaum tseem hluas. Rov qab tom qab ntawd kev tsim khoom tau khiav hauv kev cob qhia me me nrog cov cuab yeej yooj yim, feem ntau tig tawm cov khoom siv ua liaj ua teb.
Raws li cov foundry tau nthuav dav, Mr. Barry Khen tau lees paub kev lag luam loj loj rau kev lag luam casting. Nws txiav txim siab tsom mus rau pipeline casting sector. Cov khoom siv ntau lawm tau hloov kho ib kauj ruam dhau los, yog li peb tuaj yeem tsim cov qauv hlau yeeb nkab fittings rau kev txiav txim tuaj.
Cov ductile hlau tees no ua haujlwm rau cov chaw xa dej hauv nroog thiab cov kav dej txuas ntxiv ua haujlwm. Lawv ua haujlwm rau cov chaw sib cais dej nag thiab cov kav dej phwj hauv nroog. Nyob rau hauv cov dej txuag dej, lawv txhawb kev ua liaj ua teb irrigation, reservoir xa dej thiab twj tso kua mis chaw nres tsheb. Cov chaw ua si hauv chaw ua haujlwm tau txais lawv los ua cov dej txias thiab cov kav dej hauv lub Hoobkas. Txawm tias cov chaw uas nyuaj geology, xws li cov ntug dej hiav txwv ntsev-alkali av thiab collapsible loess, cov castings tuaj yeem ua haujlwm tsis tu ncua. Sab nraum zoov faus piping rau cov tsev lag luam loj, tsev kho mob thiab tsev kawm ntawv kuj xaiv cov khoom tee no.
