Dab tsi yog Welded Pipe Fittings?

Welded yeeb nkab fittings yog cov yeeb nkab sib txuas uas txuas mus tas li rau cov yeeb nkab lossis lwm yam khoom siv los ntawm vuam. Siv dav hauv roj av, tshuaj lom neeg, roj av, hluav taws xob, kev tsim kho, nkoj tsim, tshuaj thiab lwm yam lag luam. Nws lub luag haujlwm tseem ceeb yog hloov cov yeeb nkab kev taw qhia, txuas cov ceg ntoo, tswj kev ntws los yog hloov txoj kab uas hla ntawm cov yeeb nkab, thaum ua kom lub sealing, lub zog thiab kav ntev ntawm cov kav dej.
Classification ntawm Welded Pipe Fittings.
Raws li cov qauv, daim ntawv thov thiab vuam txoj kev, welded yeeb nkab fittings tuaj yeem muab faib ua hom hauv qab no:
1.Los ntawm tus qauv
Lub luj tshib: Siv los hloov cov kev taw qhia ntawm cov yeeb nkab, feem ntau ntawm cov ces kaum ntawm 45, 90 thiab 180 degrees.
Hom: Ntev vojvoog khoov (LR, R=1.5D), luv vojvoog khoov (SR, R=1.0D).
Yeeb Nkab: Siv rau cov yeeb nkab branching mus rau hauv txoj kab uas hla tees (txoj yeeb nkab yog tib txoj kab uas hla raws li lub ntsiab) thiab txo txoj kab uas hla (cov yeeb nkab ceg yog txawv txoj kab uas hla ntawm lub ntsiab). Iav reducers yog siv los txuas cov kav dej sib txawv. Lawv muab faib ua concentric reducers (kev sib haum xeeb axes) thiab eccentric reducers (eccentric axes los tiv thaiv cov dej tsub zuj zuj).
Lub hau yog siv los kaw qhov kawg ntawm cov yeeb nkab, tiv thaiv sab hauv los yog ua ib qho chaw kuaj xyuas.
Flanges yog siv los txuas cov kav dej rau cov khoom siv los ntawm bolts. Txawm hais tias tsis nruj me ntsis 'cov yeeb nkab fittings'', lawv feem ntau yog siv ua ke nrog cov khoom siv welded xws li welded caj dab flanges.
2. Los ntawm Vuam Txoj Kev
Lub taub hau Weld Fittings:
Nta: Cov yeeb nkab kawg txoj kab uas hla yog tib yam li cov yeeb nkab, los ntawm qhov kawg - mus rau - kawg kev sib cuag kom ua tiav los ntawm vuam.
Lub zog: Kev sib txuas siab zog, zoo sealing, haum rau kev kub siab, kub kub lossis loj caliber yeeb nkab.
Siv: roj, tshuaj, roj pipeline, boiler, siab hlab ntsha, thiab lwm yam.
Qhov (socket) Weld Fittings:
Nta: Cov yeeb nkab kawg yog tsim raws li cov qhov (sab hauv txoj kab uas hla me ntsis loj dua cov yeeb nkab sab nraud). Cov yeeb nkab yog ntxig thiab welded ntawm cov ces kaum.
Qhov zoo: Kev teeb tsa yooj yim, tsis muaj qhov muag tsis pom, haum rau txoj kab uas hla me me (feem ntau Tsawg dua lossis sib npaug ntawm DN40) cov kav dej hauv chav dej.
Lub Hom Phiaj: Cov kav dej huv huv rau cov khoom noj, tshuaj, kev sib txuas cov cuab yeej, thiab lwm yam.
Threaded Weld Fittings
Nta: Qhov kawg ntawm kev sib koom tes yog threaded, threaded rau cov yeeb nkab, ces welded thiab ntxiv dag zog rau ntawm qhov sib koom ua ke.
Qhov zoo: Qhov yooj yim ntawm kev sib txuas threaded yog ua ke nrog kev sib khi ua haujlwm ntawm vuam, tab sis nws daim ntawv thov tsawg dua.
ii. Core Advantages ntawm Welded Fittings
High Strength Connection: welding txheej txheem, ib qho kev sib koom ua ke tag nrho yog tsim los ntawm cov yeeb nkab thiab cov yeeb nkab, uas tuaj yeem tiv taus kev kub siab, kub thiab kev co kom tsis txhob xoob lossis xau.
Ntev- lub sij hawm ruaj khov: Welded pob qij txha yog corrosion thiab qaug zog resistant, haum rau ntev - lub sij hawm ua hauj lwm los yog hnyav ib puag ncig (xws li seafloor lossis suab puam).
High Adaptability: Cov kev xav tau sib txawv tuaj yeem ua tau los ntawm kev xaiv cov khoom sib txawv (xws li carbon steel, stainless hlau, alloy steel) thiab cov txheej txheem vuam (xws li phau ntawv thiab tsis siv neeg vuam).
Kev Ua Tau Zoo Tshaj Plaws Zoo Tshaj Plaws: Kev nkag mus rau qhov vuam (xws li lub taub qab vuam) ua kom tsis muaj qhov xau thiab tsim nyog rau kev xa cov tshuaj lom neeg, hluav taws kub thiab kim tshaj tawm.
III. Daim ntawv thov Scenario ntawm Welded Yeeb Nkab Fittings
* ** Roj & Roj Kev Lag Luam: ** Cov khoom siv uas yuav tsum tau muaj kev kub siab thiab corrosion resistant media xws li cov kav dej ntev, cov khoom siv hauv lub taub hau, compressor chaw nres tsheb, thiab lwm yam.
* ** Tshuaj lom neeg, kev lag luam tshuaj: ** cov hlab ntsha, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob thiab lwm yam khoom siv yeeb nkab, cov tshuaj tiv thaiv corrosion, kub tsis kam.
* ** Fais fab kev lag luam: ** Boilers, chav turbines, nuclear fais fab nroj tsuag, thiab lwm yam., xav tau lub zog siab, kub resistant chav kav.
* ** Kev Tsim Kho thiab Kev Ua Haujlwm Hauv Pej Xeem:** Kev siv dej, cua sov, kav hluav taws xob, thiab lwm yam, yuav tsum tau ua haujlwm ntev - lub sijhawm ruaj khov nrog cov nqi qis - tus nqi kho.
* ** Shipbuilding thiab Marine Engineering:** Marine pipelines thiab subsea pipelines yuav tsum yoog rau kev co thiab seawater corrosion ib puag ncig.
IV. INTRODUCTION Cov txheej txheem ntau lawm ntawm Welded Yeeb Nkab Fittings
* ** Kev Xaiv Khoom: ** xaiv cov khoom (xws li . 304 stainless hlau, L245 carbon steel) raws li cov yam ntxwv nruab nrab (xws li, corrosivity, kub).
* ** Txheej Txheem: ** Cov yeeb nkab ntxhib yog tsim los ntawm forging, stamping, kub nias, txias sib sau, thiab lwm yam.
** Kev Ua Haujlwm: ** Txiav qhov kawg thiab ua haujlwm ntawm lub bevel (xws li V-groove ntawm pob tw vuam yeeb nkab fittings) kom ntseeg tau tias vuam zoo.
Kev kho cua sov: Txo siab, txhim kho microstructure, txhim kho ductility thiab corrosion kuj ntawm cov yeeb nkab fittings.
Kev kho deg: polishing, sanding los yog pickling kom tau raws li kev cai huv lossis kev tiv thaiv corrosion.
Kev ntsuam xyuas thiab kev sim: Tsis yog- kuaj kev puas tsuaj (piv txwv li, X-ray, kuaj ultrasonic) thiab kev ntsuas siab tau ua kom ntseeg tau tias ua tau raws li qhov yuav tsum tau ua.
