Alloy raj tuaj yeem muab faib ua: qis alloy tube, alloy qauv raj, siab alloy raj, kub resistant acid stainless raj, kub kub alloy raj.

Cov raj hlau rau cov kav dej, cov khoom siv thermal, kev lag luam tshuab, roj av, geological drilling, thawv, tshuaj lom neeg kev lag luam, tshwj xeeb lub hom phiaj steel raj, thiab lwm yam.

Cov txheej txheem tsim khoom sib txawv, thiab muab faib ua kub dov (extrusion) seamless steel raj thiab txias rub (dov) seamless steel raj ob.

Kub dov seamless steel raj tau muab faib ua cov raj hlau dav dav, qis thiab nruab nrab siab boiler raj, siab siab boiler raj, hlau alloy steel hlab, stainless hlau hlab, roj av tawg hlab, geological hlab thiab lwm yam steel hlab.

Txias dov (dial) seamless steel yeeb nkab ntxiv rau cov yeeb nkab dav dav, qis thiab nruab nrab siab boiler steel yeeb nkab, siab siab boiler steel yeeb nkab, alloy steel yeeb nkab, stainless hlau yeeb nkab, roj av tawg yeeb nkab, lwm yam steel yeeb nkab, kuj muaj xws li carbon nyias- walled steel yeeb nkab, alloy nyias-walled steel yeeb nkab, stainless hlau yeeb nkab, tshwj xeeb-zoo li tus steel yeeb nkab.Cov txheej txheem muaj xws li:GB / T8162-2008 (seamless steel raj rau cov qauv)GB / T8163-2008 (seamless steel raj rau kev thauj mus los),GB3087-2008 (seamless steel raj rau qis thiab nruab nrab siab boiler),GB5310-2008 (seamless steel raj rau kev kub siab boiler), GB5312-2009 (seamless steel raj rau carbon steel thiab carbon manganese hlau rau nkoj),GB6479-2013 (seamless steel raj rau high-pressure chiv khoom), etc.Yog tias koj txaus siab rau peb cov khoom, thov hu rau peb los ntawm email.
