Welded kav, thiab lawv tau ua li cas?
Welded kav yog hlau tub paj tsim los ntawm dabtsi yog khoov thiab vuam hlau daim hlau lossis coils. Cov txheej txheem cuam tshuam cov qauv tiaj tus hlau mus rau hauv cov txheej txheem cylindrical, tom qab ntawd vuam ream tshuaj zoo li ERW (hluav taws xob vuam) lossis pom (submerged arc vuam). Cov hau kev no ua kom muaj zog, xau pob qij txha ua ke haum rau ntau yam kev siv. Welded kav yog tus nqi-ua tau zoo thiab muaj nyob rau hauv cov kab zauv loj, ua rau lawv zoo tagnrho rau kev tsim khoom, kev tsim kho, thiab roj & roj tsheb thauj. Tsis zoo li cov kav dej Seamless, lawv muaj cov kab weld pom tab sis muab lub zog sib piv rau cov ntawv thov feem ntau.
Dab tsi yog qhov zoo ntawm welded pipes hla cov kav dej seamless?
Welded kav yog pheej yig dua los tsim thiab muaj nyob hauv qhov loj me, ua rau lawv zoo tagnrho rau cov phiaj xwm infrastructure. Lawv tuaj yeem raug kho nyob rau hauv ntev thiab phab ntsa tuab, muab cov ntsiab siv rau kev siv sib txawv. Thaum lub sij hawm seamless yog qhov muaj zog dua nyob rau hauv huab siab, welded kav yog txaus rau cov khoom siv tsis tshua muaj dej zoo li cov kav dej thiab cov qauv kev pab txhawb. Cov kev siv vuam niaj hnub tau txhim kho lawv cov kev pheej hmoo, txo qhov kev pheej hmoo ntawm seam ua tsis tiav. Tsis tas li ntawd, welded kav yog sai dua los tsim ua, kom ua tiav qhov kev ua tiav sai sai.
Cov ntaub ntawv twg yog siv rau welded kav?
Cov hlau cov hlau yog cov khoom siv feem ntau vim nws lub zog thiab kev pheej yig. Stainless hlau welded kav yog siv nyob rau qhov twg corrosion kuj xav tau, xws li hauv cov nroj tsuag tshuaj lossis ua zaub mov noj. Aluminium thiab tooj liab welded kav yog lub teeb kev xaiv rau HVAC thiab hluav taws xob conduits. Qee cov ntawv teev tshwj xeeb siv cov ntaub ntawv hlau loj lossis cov npe npib nyiaj npib rau cov khoom siv kub siab. Qhov kev xaiv yog nyob ntawm cov yam zoo li tus nqi, ib puag ncig, thiab kev xav tau kho txhua yam.
Welded Pipes feem ntau siv?
Lawv tau dav siv hauv cov roj thiab roj pipelines, cov tshuab faib dej hauv dej, thiab kev tsim kho. Automotive pa nqus tshuab feem ntau siv cov kav dej nyias welded welded kav rau durability thiab kub tsis kam. Muaj Machinery Relies Ntawm Cov Kav Dej Welded Rau Cov Tshuab Hydraulic Thiab Pneumatic. Lawv kuj yog qhov tseem ceeb hauv kev ua liaj ua teb thiab dej phwj tuaj vim lawv cov tshuaj nplaum tsim. Yuav luag txhua txoj kev lag luam tseem ceeb siv welded kav dej hauv qee lub peev xwm.
Yuav ua li cas koj thiaj li paub tias qhov zoo ntawm welded kav?
Kev tswjhwm zoo yog suav nrog kev sim ua tsis tau muaj kev puas tsuaj (NDT) zoo li ultrasonic, xoo hluav taws xob, lossis hydrostatic sim los xyuas qhov txawv. Cov chaw tsim khoom ua raws cov qauv hauv ntiaj teb (piv txwv li, API 5L, ASTM A53) kom ntseeg tau cov khoom thiab qhov tseeb. Kev kuaj pom kev kuaj xyuas cov kev kuaj xyuas saum npoo av zoo li cov kab nrib pleb lossis tsis sib luag. Kom zoo txheej thiab galvanization tiv thaiv corrosion nyob rau hauv ib puag ncig. Cov ntawv pov thawj thib peb thiab tshuaj xyuas kev lees paub ntxiv.
