Kev tshuaj xyuas cov yeeb nkab steel thiab MTC traceability chaw kuaj daim ntawv qhia:ASTM A53 B/ASTM A106 B/API 5L IB
Txhawm rau kom ntseeg tau tias cov khoom siv steel yeeb nkab ua tau raws li cov neeg siv khoom xav tau, tus neeg sab nrauv tau ua qhov kev soj ntsuam nruj nruj thiab kuaj xyuas qhov chaw ntawm cov khoom.
1. Kev tshuaj xyuas cov yeeb nkab steel
Cov ntsiab lus tshuaj xyuas muaj xws li:
Nto tiav: xyuas kom tsis muaj qhov tsis xws li tawg, qhov, xeb, thiab lwm yam.
Thaum kawg lub ntsej muag: xyuas kom meej tias cov txiav yog tiaj thiab tsis muaj burr.
Dimensions: Sampling ntsuas ntawm steel yeeb nkab txoj kab uas hla thiab phab ntsa thickness kom ua raws li tus qauv specifications.
2. MTC thiab cov khoom traceability tshuaj xyuas
Random xyuas cov ntaub ntawv pov thawj zoo (MTC) ntawm qee cov kav hlau los xyuas seb lawv puas ua raws li cov khoom siv tiag tiag. Tshawb xyuas qhov tseeb thiab traceability ntawm MTC los ntawm cov ntaub ntawv xws li serial tooj thiab batch naj npawb los xyuas kom meej tias qhov chaw ntawm cov khoom yog tseeb thiab txhim khu kev qha.
