NEEG KHO TSHUAB THIAB COV CULTIVS NTAWM ASTM A106 Qib B Steel Yeeb

1. Pib

Hauv thaj teb ntawm kev lag luam piping thiab siab - kub,ASTM A106 Qib B Carbon Steel Yeeb Nkabyog ib qho ntawm cov khoom siv siv dav dav. Nws cov koob meej nyob hauv nws txoj kev sib xyaw ntawmsiab dua zog, kev du me me, thiab txhim khu kev kub tiv thaiv, ua rau nws zoo tagnrho rau kev thauj cov chav, roj, roj, thiab lwm yam kua nyob hauv cov chaw kub thiab ntsuas.

Nkag siab lubNeeg kho tshuab thiab cov yam ntxwv cov yam ntxwvNtawm Astm A106 qib B yog qhov tseem ceeb rau ob tus kws ua haujlwm thiab cov kws tshaj lij tshwj xeeb. TusTshuaj Muaj Tshuajtxiav txim siab cov khoom siv tawv tawv, corrosion tsis kam, thiab weldability, thaum lubCov Khoom Siv Neeg Kho TshuabTxhais li cas cov yeeb nkab coj hauv kev kub siab thiab thauj khoom.

NtawmHUAYANG STEEFF YEEB NKAB, peb tsom rau kev tswj kom muaj kev sib npaug zoo meej ntawmlub zog thiab hloov tau muaj zoglos ntawm kev tswj hwm me me metallurgical thiab kev ntsuas qib siab tshaj plaws. Kab lus no tshawb nrhiav li cas cov tshuaj lom neeg thiab tshuab ua haujlwm cuam tshuam cov yeeb nkab ua haujlwm thiab kev ntseeg tau.
