ISO 9001: 2015
ASME BPVC Section II, Part D
EN 10204 Hom 3.1 / 3.2 (Mill Test Certificate)
PED 2014/68/EU (rau European lag luam)
API 5L / API 5CT (thaum teev tseg)
Kev tshuaj xyuas thib peb los ntawm BV, SGS, TUV, lossis Lloyds thaum thov.
Q7: Cov kev xeem uas tsis yog kev puas tsuaj (NDT) ua li cas?
A: Standard xeem suav nrog:
Kev kuaj ultrasonic (UT)rau qhov tsis xws luag.
Eddy Current Testing (ECT)rau qhov tsis xws luag.
Hydrostatic Testrau siab ncaj ncees.
