Thaum koj tab tom nrhiav thawj zaug rau cov yeeb nkab steel, seb puas yog rau cov nroj tsuag desalination, cov roj rig, lossis nuclear fais fab nroj tsuag, thawj lo lus nug koj yuav tsum nug koj tus kheej yog "Kuv puas xav tau seamless, welded, los yog forged "pipes"? Cov peb no Txhua hom muaj cov txiaj ntsig sib txawv thiab yog li tsim nyog rau kev siv sib txawv thiab ib puag ncig. Muaj ntau yam uas yuav tsum tau xav txog thaum xaiv qhov tsim nyog rau ib qhov project.

Cov kws ua haujlwm yuav paub cov lus teb rau lo lus nug no intuitively, tab sis cia peb siv sijhawm ib pliag los tshawb txog cov yeeb nkab seamless, welded yeeb nkab thiab forged kav thiab lawv ntau yam khoom.

1. Seamless yeeb nkab

Cia peb pib nrog seamless yeeb nkab. Raws li lub npe qhia, cov yeeb nkab seamless yog cov yeeb nkab uas tsis muaj seams lossis welds.

Manufacturing thiab Application:

Seamless tubing tuaj yeem tsim tau siv ntau txoj kev sib txawv, feem ntau nyob ntawm qhov xav tau txoj kab uas hla, lossis qhov sib piv ntawm txoj kab uas hla mus rau phab ntsa thickness. Feem ntau hais lus, cov txheej txheem kev tsim cov yeeb nkab seamless pib nrog cov hlau tsis zoo rau hauv daim ntawv ua haujlwm ntau dua - cov khoom kub kub. Tom qab ntawd ncab nws thiab thawb lossis rub nws hla ib daim ntawv. Qhov no hollow raj ces mus los ntawm ib tug extrusion txheej txheem uas nws yog yuam los ntawm ib tug tuag thiab mandrel. Qhov no yuav pab ua kom lub puab kab uas hla thiab txo cov sab nraud.

Seamless steel yeeb nkab feem ntau yog siv los thauj cov kua dej xws li dej, roj av, pov tseg thiab huab cua. Nws tseem yog ib qho tseem ceeb heev nyob rau hauv ntau qhov kev kub siab, corrosive ib puag ncig xws li roj thiab roj, lub zog tsim hluav taws xob thiab kev lag luam tshuaj.

Qhov zoo:

Lub zog siab: Seamless yeeb nkab muaj qhov pom tseeb zoo ntawm tsis muaj seams, yog li yuav tsis muaj cov seams tsis muaj zog. Qhov no txhais tau hais tias feem ntau, seamless yeeb nkab tuaj yeem tiv taus 20% kev ua haujlwm siab dua li cov welded yeeb nkab ntawm tib cov khoom qib thiab loj.
High Resistance: Qhov tsis muaj seams txhais tau tias cov kav dej seamless tuaj yeem muab kev tiv thaiv corrosion ntau dua, vim muaj teeb meem xws li impurities thiab tsis xws luag yuav tshwm sim ntawm cov welds.

Tsawg kev sim: Tsis tas yuav hais, seamless tubing tsis tas yuav tsum tau kuaj rau qhov kev ntseeg siab - tsis muaj vuam txhais tau tias tsis muaj kev sim!

2. Welded yeeb nkab

Muaj peb hom welded kav: sab nraud welding, puab txoj kab uas hla vuam los yog ob sab welding. Qhov feem ntau denominator yog tias lawv txhua tus muaj seams!

Kev tsim cov txheej txheem ntawm cov yeeb nkab welded pib los ntawm dov ib co coil ntawm cov hlau mus rau qhov xav tau tuab los ua ib lub tiaj tiaj los yog phaj. Nws yog ces dov thiab cov seams ntawm lub resulting raj yog welded nyob rau hauv ib tug chemically nruab nrab ib puag ncig.

Hais txog hom hlau twg yog weldable, austenitic steels feem ntau yog cov weldable tshaj plaws, thaum ferritic steels weld nyias ntu. Duplex steels yog tam sim no suav hais tias yog tag nrho weldable, tab sis lawv xav tau kev saib xyuas ntau dua li cov hlau austenitic.

Welded yeeb nkab tsim tshuab tau suav tias tau txhim kho zoo heev nyob rau ob peb xyoos dhau los. Arguably qhov tseem ceeb tshaj plaws ua ntej yog kev txhim kho cov txheej txheem vuam siv cov khoom siv hluav taws xob siab. Qhov no zoo heev txhim kho cov yeeb nkab welded lub peev xwm kom tsis txhob muaj kev xeb thiab kev sib koom ua ke.

Thaum cov seams nyob rau hauv welded yeeb nkab yog theoretically raug kom nws tsis muaj zog, kev tsim thiab cov txheej txheem kev ruaj ntseg zoo tshaj niaj hnub no. Qhov no txhais tau hais tias ntev li ntev tau hais tias qhov kub thiab txias siab ntawm cov yeeb nkab welded tsis tshaj, tsis muaj laj thawj vim li cas nws yuav tsum tsis ua raws li cov yeeb nkab seamless hauv ntau qhov kev lag luam.

Tus nqi: Ib qho txiaj ntsig zoo ntawm cov yeeb nkab welded yog tias nws yog qhov pheej yig tshaj ntawm txhua hom yeeb nkab thiab yooj yim dua.
Kev sib raug zoo: Nws feem ntau lees paub tias cov yeeb nkab welded yog qhov zoo sib xws hauv cov phab ntsa tuab dua li cov yeeb nkab seamless. Qhov no yog vim cov txheej txheem tsim khoom pib nrog ib daim ntawv hlau.
Surface Quality: Tsis txhob siv cov txheej txheem extrusion kuj txhais tau hais tias qhov chaw ntawm cov kav dej welded tuaj yeem ua tau zoo dua li cov kav dej seamless.
Ceev: Welded yeeb nkab yuav tsum luv luv procurement lead lub sij hawm vim cov txheej txheem tsim yooj yim.

3. Forged yeeb nkab

Hlau forging yog cov txheej txheem hlau uas siv lub zog compressive thiab huab cua kub thiab siab los tsim cov hlau.

Kev tsim cov kav dej forged pib los ntawm kev tso ib daim hlau (txawm tias 6% molybdenum, super duplex, duplex, stainless hlau, npib tsib xee alloy) nruab nrab ntawm sab saud thiab qis. Cov hlau yog tsim los ntawm cua sov thiab siab rau hauv cov duab uas xav tau thiab tom qab ntawd ua tiav los ntawm kev siv tshuab ua kom tau raws li txhua qhov yuav tsum tau ua.

Cov txheej txheem tsim khoom no ua rau muaj tus nqi ntxiv ntawm forged tube.

Ntau qhov zoo ntawm forged raj txhais tau hais tias nws muaj ntau yam kev siv hauv ntau yam xws li roj thiab roj, hydraulic machinery, fertilization thiab tshuaj lom neeg kev lag luam. Qhov tseeb hais tias forged steel tsis muaj seams los yog welds tso cai rau nws ua tiav muaj peev xwm muaj teeb meem los yog corrosive tshuaj thiab lawv fumes. Yog li ntawd, nws tuaj yeem siv rau hauv ntau qhov kev lag luam hnyav.

High Strength: Forged kav feem ntau tsim cov khoom muaj zog thiab txhim khu kev qha kawg vim forging ua rau cov hlau cov nplej ntws hloov thiab ua kom zoo. Hauv lwm lo lus, cov hlau tau dhau los ua qhov zoo dua thiab cov qauv ntawm cov yeeb nkab tau hloov pauv ntau, ua rau muaj zog sheer thiab muaj kev cuam tshuam siab.
Lub neej ntev: Forging tshem tawm cov porosity, shrinkage, kab noj hniav thiab cov teeb meem txias pouring.
Economical: Cov txheej txheem forging feem ntau suav tias yog kev lag luam zoo heev vim tsis muaj cov khoom siv pov tseg.
Flexibility: Cov txheej txheem steel forging yog hloov tau yooj yim thiab tuaj yeem tsim cov raj hauv ntau qhov sib txawv.
