1. ERW steel yeeb nkab
ERW steel yeeb nkab yog ib lo lus dav dav rau hluav taws xob tsis kam vuam steel kav, Hluav taws xob tiv thaiv vuam, hu ua ERW. Resistance welded steel kav muab faib ua ob hom: AC welded steel kav thiab DC welded steel kav.
AC vuam yog muab faib ua tsawg zaus vuam, nruab nrab zaus vuam, ultra-nruab nrab zaus vuam thiab siab zaus vuam raws li qhov zaus. High zaus vuam yog tsuas yog siv rau zus tau tej cov nyias-walled steel kav los yog zoo tib yam tuab-walled steel kav. High zaus vuam yog muab faib ua kev sib cuag vuam thiab induction vuam. DC vuam feem ntau yog siv rau cov kav hlau me me.

2. SAW steel yeeb nkab
SAW steel yeeb nkab yog lub npe tag nrho ntawm Submerged Arc Vuam Steel Pipe. Nws yog cov yeeb nkab steel tsim siv submerged arc vuam tshuab. Qhov ceev tam sim no tsim los ntawm cov txheej txheem no yog siab heev. Cov txheej txheej flux tiv thaiv cov cua kub sai sai thiab ua rau nws nyob hauv qhov chaw vuam. Submerged arc vuam muaj cov yam ntxwv ntawm cov vuam zoo, kev ua haujlwm siab, tsis muaj lub teeb arc thiab cov pa luam yeeb me me. Submerged arc vuam steel kav yog dav siv nyob rau hauv cov hlab ntsha siab, cov yeeb nkab fittings manufacturing, kab teeb thiab kab, cov dej tsis tshua muaj siab, thiab cov phiaj xwm steel.

Nws tuaj yeem pom tau tias ERW steel kav tuaj yeem paub qhov txuas txuas txuas ua haujlwm hauv kev tsim khoom, nrog rau kev ua haujlwm siab thiab cov nqi tsim khoom tsawg; thaum SAW steel kav yog ua tiav los ntawm cov hlau phaj, nrog kev ua haujlwm tsawg thiab cov nqi ntau lawm. ERW cov kav dej yog tsim rau cov kav dej me me, thaum cov kav dej SAW tuaj yeem txuas cov kav dej loj.
