Hlau yeeb nkab kub ua haujlwmyog ib qho tseem ceeb technology hauv steel yeeb nkab ntau lawm. Nws suav nrog kev siv qhov kub thiab txias los ua kom cov yas deformation hauv lub billet, ua tiav shaping thiab kev ua tau zoo. Siv dav hauv petrochemical, mechanical manufacturing, thiab lwm yam kev lag luam, nws qhov zoo ncaj qha txiav txim siab cov khoom siv kho tshuab, qhov tseeb qhov tseeb, thiab kev pabcuam lub neej ntawm cov yeeb nkab steel.
Hais txog peb
HT PIPE yog ib tug thawj coj stockist thiab thoob ntiaj teb exporter nrog ntau tshaj 16 xyoo ntawm kev txawj ntse nyob rau hauv thoob ntiaj teb kev lag luam. Peb muab cov kav dej, daim hlau, cov kab tuav, thiab ntau yam ntawm cov yeeb nkab fittings, flanges, thiab li qub.Tiv tauj pebtam sim no rau cov quotes dawb thiab cov ntaub ntawv khoom ntiag tug.
Basic Principles of Steel Pipe Kub Ua Haujlwm Technology
Nws siv cov yam ntxwv ntawm kev nce hlau plasticity thiab txo lub zog thiab hardness ntawm qhov kub thiab txias. Sab nraud quab yuam yog siv los ua cov yas deformation ntawm lub billet, thaum cov kev ntxhov siab sab hauv raug tshem tawm ib nrab los ntawm atomic diffusion, tiv thaiv kev puas tsuaj.
Cov txheej txheem tseem ceeb ntawm Steel Yeeb Nkab Kub Ua Haujlwm Technology
Kev npaj Billet
Kev npaj Billet suav nrog peb kauj ruam: xaiv, txiav, thiab kho qhov chaw. Billets txuam nrog cov khoom tiav lawm yuav tsum tau xaiv, txiav rau qhov loj me, thiab nplai nplai, roj stains, thiab lwm yam impurities tshem tawm kom tsis txhob cuam tshuam rau kev ua haujlwm tom ntej.
Cov txheej txheem cua sov
Cov cua sov yog ib qho tseem ceeb heev thiab yuav tsum ua raws li lub hauv paus ntsiab lus ntawm "cov cua kub sib xws thiab kev tswj qhov kub thiab txias." Cov cuab yeej siv feem ntau suav nrog cov kab hluav taws xob taug kev, lub tshuab hluav taws xob tig lub tshuab hluav taws xob, thiab cov cua kub induction cua sov, los tiv thaiv overheating, hlawv, los yog qhov kub tsis sib xws ntawm cov khoom siv hluav taws xob.
Taug kev beam furnaces yog tsim rau loj- ntim, ntau- cov ntawv qhia tshwj xeeb, cov tshuab hluav taws xob tig tau tsim nyog rau cov cua sov tsis tu ncua ntawm seamless steel yeeb nkab billets, thiab induction cua sov rauv muab cov cua sov ceev thiab ib puag ncig zoo. Cov cua kub kub yog txiav txim siab los ntawm cov khoom siv, xws li 1100-1250℃rau cov pa roj carbon zoo tib yam thiab 1050-1200℃rau stainless hlau.
Txheej txheem txheej txheem
Seamless steel yeeb nkab txoj kev muaj peb kauj ruam: kub dov tho, nruam dov, thiab sizing: tho tsim ib tug hollow raj, nruam dov adjusts cov specifications, thiab sizing calibrates lub sab nraud txoj kab uas hla.
Welded steel yeeb nkab txoj kev muaj xws li phaj dov thiab vuam: lub phaj yog dov mus rau hauv lub raj zoo, thiab ces welded siv txoj kev xws li submerged arc vuam thiab siab - zaus induction vuam.
Phaj dov yuav tsum xyuas kom meej qhov sib txawv ntawm cov npoo thiab txais tau roundness. Submerged arc vuam yog tsim rau loj - txoj kab uas hla, tuab - cov kav dej, thaum siab - zaus induction vuam yog tsim rau loj ntau lawm ntawm me me - txoj kab uas hla, nyias - cov kav dej.
Kev kho cua txias
Kev kho cua txias yuav tsum raug xaiv raws li cov khoom siv thiab kev ua tau zoo, siv cov cua txias, cua txias, lossis dej txias: ntuj txias yog tsim rau cov pa roj carbon zoo tib yam, cua txias yog tsim rau cov hlau alloy, thiab dej txias yog tsim rau cov kav hlau uas xav tau lub zog siab. Qhov ntsuas cua txias yuav tsum tau tswj kom tsis txhob tawg.
Kev ua haujlwm tom ntej
Kev ua haujlwm tom qab suav nrog kev ncaj, txiav qhov xaus, tsis yog- kuaj kev puas tsuaj, kev kho saum npoo, thiab kev kos npe thiab ntim khoom. Kev ua kom ncaj ncaj ua kom muaj kev ncaj ncees, txiav qhov kawg ua kom qhov tseeb ntev, tsis yog - kev kuaj kev puas tsuaj tshem tawm qhov tsis xws luag, kev kho saum npoo muab xeb thiab tiv thaiv corrosion, thiab kos npe thiab ntim khoom yooj yim rau kev khaws cia thiab kev thauj mus los.
Thermal processing Requirements for Different Steel Pipe Materials
Carbon Steel Pipes
Cov pa roj carbon steel kav tau muab faib ua qis, nruab nrab, thiab siab carbon steel raws li cov ntsiab lus carbon: qis- carbon steel muaj kub ua haujlwm kub ntawm 1150-1250 degree, nrog cov yas zoo thiab ua haujlwm yooj yim. Nruab nrab- carbon steel yog ua tiav ntawm 1100-1200 degree, yuav tsum tau tiv thaiv cov nplej coarsening. High-carbon steel yog ua tiav ntawm 1050-1150 degree, yuav tsum muaj kev tswj xyuas nruj ntawm cua sov thiab tuav lub sijhawm, thiab ua kom txias txias kom tsis txhob tawg.
Alloy Steel Pipes
Kev ua haujlwm kub kom haum ntawm cov kav hlau hlau yog nyob ntawm cov ntsiab lus alloying: chromium alloy kav yog ua tiav ntawm 1100-1200 degree, yuav tsum muaj sijhawm tuav txaus. Manganese alloy kav yog ua tiav ntawm 1150-1250 degree, ua raws li normalizing tom qab tsim. Nickel alloy kav yog ua tiav ntawm 1100-1250 degree, ua raws li ntuj lossis cua txias. Molybdenum alloy kav yog ua tiav ntawm 1150-1200 degree, ua raws li tempering tom qab tsim.
Stainless hlau kav
Stainless hlau kav muab faib ua austenitic, ferritic, thiab martensitic hom: austenitic stainless hlau yog ua tiav ntawm 1050-1200 degree, tsis txhob deformation hauv qab 900 degree, ua raws li kev kho mob tom qab tsim. Ferritic stainless hlau yog ua tiav ntawm 1000-1150 degree, nrog tswj cua sov thiab cua txias; martensitic stainless hlau yog ua tiav ntawm 1050-1150 degree, ua raws li quenching thiab tempering.
