2, on the non ductile transition temperature
“ new content regulation ” 3.2.12.2 of the common pressure container of metal ductile transition temperature can be reference to "GB150-2011< > 11.4.9; pressure vessel; selection schedule standard interpretation" in GB150.4, not listed on the metal ductility transition temperature can refer to the relevant material manual.
3, on the design requirements of the fast open type pressure vessel
The designer shall stipulate the technical requirements of safety interlock device for quick open door use environment, calibration cycle and testing method in the design document, the device shall meet the relevant safety technical specification, design basis and standard requirements. If the quick opening type pressure container structure has safety interlock function, the safety interlock device can not be arranged in addition.
(four) manufacturing
1, on the level of manufacturing license
Pressure vessel manufacturing license level is still in accordance with the "boiler and pressure vessel manufacturing supervision and management measures" (AQSIQ Decree No. twenty-second) Regulations (the "special equipment directory" adjustment, A3 grade pressure vessel manufacturing license project has been canceled shell plate manufacturing).
2, on separate factory compression components, parts of the inspection
“ new volume ” after the implementation of the factory, and the need for separate pressure vessel element, supervision and inspection of components with spherical shell plate with welding cylinder, head, spherical tank, the heat exchange tube bundle welding connection method.
3, on the use of strain hardening technology to manufacture pressure vessels
In the national standard GB/T18442.7 issued prior to the implementation of manufacturing enterprises may refer to the national standard draft for approval "fixed cryogenic insulated cryogenic pressure vessel seventh part: container strain strengthening technology regulations" (available in http://www.cscbpv.org.cn to download)Develop enterprise standards, and in accordance with the provisions of the enterprise standard for self declaration or record.
Enterprises for the first time using the strain strengthening container cryogenic insulated cryogenic pressure technology manufacturing, should be in accordance with the new regulations containing “ ” 4.1.2, invited cryogenic insulated cryogenic pressure vessel type experiment of vacuum insulated cryogenic vessel type test. Using the strain strengthening technology for manufacturing content, manufacturing units should be in accordance with the new regulations. “ ” 4.2.7.3 (4) the strain strengthening technology to verify the trial sample container, trial process shall notify the test organization in advance and after inspection supervision and inspection agencies.
4, on the type of test institutions
“ new capacity ” 4.1.2 type test bottle type container temporarily by cylinder type test after approved by the General Administration of quality inspection agencies of the state.
