In November, a number of new valve standards will be officially implemented.
according to the valve standards sponsored by the National Technical Committee for valve standardization and the National Technical Committee for standardization of wood block full pressure relief device on the release board, the domestic packaging paper recovery rate needs to be raised to 89% and 91% in 2019 and 2020 respectively. The Ministry of industry and information technology issued a number of industry standards with the approval of Announcement No. 47 of 2014
according to the standard announcement notice on valve standards sponsored by the National Technical Committee for valve standardization and the National Technical Committee for safety relief device standardization, the Ministry of industry and information technology approved the release of a number of industry standards in Announcement No. 47 of 2014
there are 13 standards related to the valve industry. Among the 13 standards, 5 are replaced by new standards, and 8 are new standards
the five new valve standards replaced are:
jb/t instrument valve group replaces the previous standard jb/t
"jb/t valve steel castings appearance quality requirements" replaces the previous standard "jb/t", and the adopted standard is ansi/mss sp-, mod
jb/t industrial valve supply requirements replaces the previous standard jb/t
"jb/t valve electric device life test procedure" replaces the previous standard "jb/t"
"jb/t year is a one-year method for the preparation of valve electric device models for the rare earth industry" replaces the previous standard "jb/t"
the eight new valve standards are: jb/t technical conditions for pressure bearing forged steel for thermal power supercritical and ultra supercritical parameter valves, jb/t General requirements for thermal power supercritical and ultra supercritical parameter valves, jb/t extraction check valves for steam turbines, jb/t specification for low temperature test devices for valves, jb/t 12004 technical conditions for low vacuum butterfly valves used to ensure safety during the test process Jb/t steel pipe welding ball valve, jb/t blast furnace TRT system quick cut butterfly valve
the above 13 new valve standards will be officially implemented on November 1, 2014. The implementation of the new standard will make up for the deficiencies of the current standard, and is more conducive to give full play to the technical support role of standardization in the great development of the valve industry, and promote the transformation and upgrading of the valve industry
