Hebei Huayang Steel Pipe Co., Ltd yog ib qho ntawm cov ua lag luam thiab cov neeg muag khoom ntawm lsaw api 2b carbon steel yeeb nkab dn420 hauv Suav teb. Thov koj xav tias dawb mus yuav pheej yig lsaw api 2b carbon steel yeeb nkab dn420 los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.
Cov qauv raws li lub hauv paus, qhov ntev raws li qhov pov thawj
DN420 ua raws li API Spec 2B txoj hauv kev, Ameslikas tsim rau cov khoom siv, nrog cov qauv qhia meej rau lub zog, weldability, thiab toughness. Peb feem ntau siv LSAW submerged arc ncaj seam vuam muaj kev ruaj ntseg ntau dua rau cov kab nruab nrab mus rau qhov loj. Tom qab dov daim hlau mus rau hauv lub voj voog, ob -sab submerged arc vuam nkag mus rau hauv lub seam hauv ib qho dhau los, ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom. Huayang cov kav dej ua ke tuaj nrog cov ntaub ntawv qhia txog kev sib koom ua ke thiab cov yeeb nkab xov tooj, kom ntseeg tau tias cov khoom sib xyaw ua ke, cov khoom siv vuam, thiab cov khoom siv hluav taws xob. Ntawm 420mm txoj kab uas hla, qhov loj me no ua rau muaj qhov sib npaug ntawm qhov ua tau zoo-tsis hnyav heev lossis tsis cuam tshuam rau kev thauj khoom-cov kabmob muaj peev xwm rau hnyav- lub luag haujlwm lub luag haujlwm.
DN420 Specification Details thiab Common Applications
Nrog rau sab nraud txoj kab uas hla ntawm 420mm, feem ntau phab ntsa thicknesses li ntawm 6-14mm, thiab tus qauv ntev ntawm 6-12m, ua kom yooj yim rau tag nrho - tsheb thauj mus los thiab rhiav txiav. Peb feem ntau tswj kev sib tw hauv 1% thiab ncaj nraim hauv 1.5 hli ntawm 1m ntev, ua kom tsis muaj pob tw vuam yam tsis muaj "lub taub hau viav vias" lossis "kauv distortion" thaum tsim cov khoom siv. Qhov loj me no feem ntau txiav nrog Q355B qib steel daim hlau, txo cov teeb meem embrittlement hauv cov khoom siv welded 'txias- khoov / tshav kub- thaj chaw cuam tshuam. Thaum siv rau hauv cov khoom siv hnyav, cov kab, kab, lossis ncej ntoo khaub lig- braces, nws muaj qhov zoo tshaj plaws siv qhov chaw thiab cov khoom siv ntau dua. Nws yog tshwj xeeb tshaj yog haum rau thav duab Cheebtsam uas yuav tsum tau nyob rau ntawm - qhov chaw thib ob lub taub qab vuam los yog kab rov tav flipping rau vuam, ua kom cov neeg ua hauj lwm paub ceev thiab ceev sib dhos voj voog.
Welding thiab Processing Logic rau Hnyav Ncej
Cov qauv tubing tsis yog hais txog kev vuam seam nkaus xwb- qhov kawg kev npaj thiab kev faib tawm kev ntxhov siab yog qhov tseem ceeb sib npaug. Tom qab dov thiab sib sau, peb ua qhov kawg flaring kho thiab tag nrho - ntev straightening, ua raws li tag nrho -seam ultrasonic UT tshuaj xyuas rau daim ntawv qhia qhov chaw weld. Cov ncej feem ntau yuav tsum tau vuam lugs, muab cov phaj, lossis laser-drilled qhov. Peb ua ntej-kos qhov qhov ntev thiab "xauv" rau hauv qhov chaw ntawm lub Hoobkas ua ntej xa khoom. Peb kuj ua raws li kev cai khoov / txiav cov cai rau chamfering, drilling, thiab ua ntej - vuam txuas ntu. Lub hom phiaj yog ua ntej- kho "cov ntsiab lus kev ntxhov siab" hauv lub Hoobkas, hloov pauv ntawm- qhov chaw vuam thiab sib dhos ua haujlwm li niaj zaus.
Tiag -Lub Ntiaj Teb Cov Cai thiab Kev Pov Hwm Kev Xa Khoom
Cov cuab yeej hnyav hnyav feem ntau ua rau muaj kev vibration, cuam tshuam, thiab tawm - nruab nrab loads. Peb tsim cov ntaub ntawv kho tshuab nrog 15-20% lub zog redundancy raws li engineering specifications. Ua ntej tag nrho cov khoom xa tuaj, peb ua cov load-cov kabmob kuaj ntawm 1.3–1.5 npaug ntawm cov qauv tsim, tsim cov ntaub ntawv nkhaus rau kev ruaj khov / thauj khoom-cov kabmob ntu. DN420 feem ntau yog siv nyob rau hauv chaw nres nkoj machinery, lifting platforms, mining heavy machinery, thiab shield machine support thav duab{11}}tshwj xeeb tshaj yog rau loj -scale lateral bracing los yog rigid txheej txheej kab. Rau lub Hoobkas ntim, peb ntiav tshwj xeeb ntsug bundling rau structural tubing los tiv thaiv ovalization, cuam tshuam kev puas tsuaj, thiab twisting. Peb lub tuam txhab nyob hauv Mengcun, Hebei Xeev. Peb zoo siab tos txais tuaj xyuas cov kab ntau lawm, weld seams, flared kawg, thiab kuaj cov ntaub ntawv txhua lub sijhawm. Nrog cov txheej txheem zoo li no, kev ntseeg siab yog qhov tseem ceeb tshaj - qhov koj pom yog qhov koj tau txais, thiab kev xa khoom xa tuaj nrog kev ntseeg siab.
