Cov qauv, kev cai, thiab kev txhim kho sai ntawm cov yeeb nkab khoov Fabrication
Taw qhia:
Nrog txoj kev loj hlob sai ntawm kev lag luam piping, cov yeeb nkab khoov tau dhau los ua ib qho kev pom hauv peb lub neej niaj hnub thiab chaw ua haujlwm. Lawv pom cov ntawv thov dav hauv kev lag luam xws li hluav taws xob, roj av, dej hiav txwv, thiab tshuaj lom neeg. Lawv ua lub luag haujlwm tseem ceeb hauv kev thauj mus los ntawm cov roj, roj, thiab cov kua dej, nrog rau hauv cov tshuab dav hlau thiab cav. Muab lawv qhov tseem ceeb, ua raws li cov qauv thiab cov kev cai rau cov yeeb nkab khoov fabrication yog qhov tseem ceeb tshaj plaws.
Cov yeeb nkab khoov cov chaw tsim khoom feem ntau yog tsev cov khoom lag luam uas tsis tau ua tiav lossis ib nrab ua tiav cov yeeb nkab khoov. Txij li cov txheej txheem tsim khoom feem ntau tsim cov yeeb nkab ncaj, cov yeeb nkab khoov yuav luag txhua zaus raug rau cov txheej txheem tsim khoom ntxiv. Txhawm rau kom muaj kev nyab xeeb thaum tsim cov yeeb nkab khoov, cov txheej txheem kev nyab xeeb hauv qab no yuav tsum tau ua raws:
1. Kev tsim cov yeeb nkab khoov yuav tsum ua raws li cov qauv thiab cov kev cai. Ib qho kev sib txawv ntawm cov qauv no tsis raug tso cai, tsis hais qhov twg ntawm cov yeeb nkab khoov fabrication.
2. Cov ntaub ntawv siv rau cov yeeb nkab khoov fabrication yuav tsum tau soj ntsuam zoo. Cov yeeb nkab tsis zoo, cov khoom sib txuas, lossis cov fasteners nrog deformations, tawg, lossis lwm yam tsis zoo yuav tsum tsis txhob siv. Vuam yuav tsum tsis txhob siv los kho fasteners thiab connectors nyob rau hauv cov yeeb nkab khoov.
3. Lub hauv paus hauv paus rau cov yeeb nkab khoov fabrication yuav tsum yog theem, compact, thiab ruaj khov. Lub hauv paus hlau yuav tsum tiaj tus yam tsis muaj deformities. Thaum cov av yog mos, kev siv cheb beams los yog shims tuaj yeem ua rau kom muaj qhov hnyav thiab txhim khu kev ruaj ntseg.
4. Platform boards ntawm cov yeeb nkab khoov yuav tsum tau npaj kom huv si, nrog cov dav dav thiab ntev (tshwj tsis yog cov ntu tshwj xeeb). Txhua lub platform ntawm cov kav dej yuav tsum tau kho kom ruaj ntseg, thiab lub platform nto yuav tsum tsis txhob muaj qhov loj (tshwj tsis yog rau cov ntu tshwj xeeb).
Pipe Bend Fabrication Techniques:
Cov yeeb nkab khoov fabrication encompasses ntau txoj kev, suav nrog tab sis tsis txwv rau cov hauv qab no:
1. Open-Die Forging:
- Qhib-tuag forging yog siv rau kev tsim cov yeeb nkab me me xws li tees, lub luj tshib, thiab cov reducers nrog lub qhov (socket) vuam thiab threading. Cov txheej txheem shaping tuaj yeem yog qhov nyuaj, thiab qhov zoo thiab qhov ntev ntawm cov khoom kawg yog cuam tshuam los ntawm cov khoom siv ntom ntom, sintering kub, sintering lub sij hawm, ntxiv kom muaj nuj nqis thiab kev faib ua feem, thiab hom coupling tus neeg sawv cev.
2. Extrusion:
- Cov yeeb nkab loj khoov tuaj yeem ua tau zoo los ntawm kev siv extrusion siv ntxaib-ntsia hlau extruders.
3. Txhaj Molding:
- High-shear force yog siv los yaj cov khoom, sib cais ua hmoov zoo thiab kab noj hniav. Kev siv cov taub me me thiab cov ntsia hlau tsim nyog ua rau cov kav dej khoov tau zoo.
4. Tshuab Moulding:
- Txoj kev no yog tsim rau cov ntaub ntawv uas muaj siab yaj nro thiab tsawg sagging, ua rau nws zoo tagnrho rau cov yeeb nkab loj loj khoov.
5. Secondary forming:
- Tom qab qhov pib shaping, qhov thib ob txoj kev yuav tsum siv lub zog sab nraud thiab cua sov cov khoom kom ua tiav cov duab khoov tshwj xeeb. Cov khoom yog ces txias kom khov kho khoov.

Raws li kev lag luam piping txuas ntxiv nthuav dav, lub luag haujlwm ntawm cov yeeb nkab khoov hauv ntau daim ntawv thov loj dua. Ua raws li cov qauv thiab cov kev cai hauv cov yeeb nkab khoov fabrication yog qhov tseem ceeb rau kev ruaj ntseg thiab zoo. Fabrication txoj kev sib txawv, tab sis txhua tus yuav tsum ua raws li cov qauv tsim nyog. SINO SPECIAL METAL yog ib tus neeg muab kev ntseeg siab ntawm cov kav dej, flanges, thiab fittings, npaj los pab koj cov kev xav tau. Rau kev nug thiab kev yuav khoom, thov hu rau peb. Peb mob siab rau muab cov khoom zoo thiab kev txawj ntse kom tau raws li koj xav tau.
