Product Detail

Khoom cim npe

Covcov kav dej hauv avyog ib tug kauv steel yeeb nkab ua los ntawm tsis siv neeg ob-xaim ob-sided submerged arc vuam txheej txheem.Cov yeeb nkab yog tsim los ntawm sawb steel coils thiab extruded ntawm qhov kub thiab txias kom ntseeg tau tias nws kav ntev thiab ntev.

Lub cev thiab tshuaj lom neeg ntawm cov yeeb nkab steel (GB / T3091-2008, GB / T9711-2011 thiab API Spec 5L)
