    Cov Khoom Qhia Txog Khoom

    Cov Cim Npe Khoom

    Kawm txog A252 Qib 2 Steel Pipe:

    A252 QIB 2 Cov Yeeb Nkab Hlauyog cov yeeb nkab hlau carbon uas tsim tshwj xeeb rau kev siv rau hauv cov kav dej siab thiab cov ntawv thov kev tsim kho. Nws yog tsim raws li ASTM (American Society for Testing and Materials) cov qauv, ua kom ntseeg tau tias cov qauv zoo thiab qhov tseeb ntawm qhov ntev. Lub npe GRADE 2 qhia tias cov yeeb nkab hlau yog tsim los ntawm kev siv cov khoom siv vuam submerged arc lossis seamless welding.

    Qhov tseem ceeb ntawm ob chav submerged arc vuam:

    Ob chav submerged arc vuam, tseem hu ua DSAW, yog ib txoj kev vuam tshwj xeeb uas siv los txuas cov ntu ntawm A252 GRADE 2 steel yeeb nkab. DSAW muaj ntau qhov zoo dua li lwm txoj kev vuam, suav nrog kev vuam zoo heev, kev vuam ceev ceev, kev cuam tshuam tsawg kawg nkaus, thiab kev tswj hwm zoo ntawm cov cua sov nkag. Nws ua kom muaj kev sib txuas zoo ntawm cov yeeb nkab, ua rau lawv tsis yooj yim rau kev xau, xeb thiab kev puas tsuaj ntawm cov qauv.
