The enterprise has established EPR management system, advanced valve flange performance inspection and test center, CAD valve flange design center and three-dimensional simulation manufacturing test design system, and introduced direct reading spectrum analyzer, pressure test bench, chemical composition analysis, pressure measurement system, etc Mechanical performance test, hardness test, spectrum analysis, ultrasonic thickness gauge and various special equipment provide a strong guarantee for the production of high quality valve flange. It not only improves the quality and speed of product development, but also makes the quality assurance system more scientific and complete. It is the first to pass is09001:2008 international quality system certification, IS014001 environmental system certification, CE EU safety certification and National Bureau of quality supervision (TS) certification, and has passed the confirmation of good standardization system and Metrological Inspection System.
