From;    Author:Stand originally

Supervisory bureau of technology of quality of each province, municipality, municipality directly under the Central Government, each concern an unit:

" boiler pressure vessel uses board " (GB713-2008) and " intensity of conduit boiler pressure part is calculated " (GB/T9222-2008) carried out on July 1, 2008 at was being mixed on September 1, 2008 respectively. To resolve the real difficulty of the enterprise in transition of new old standard, those who assure afore-mentioned standards is successful carry out, be in business relevant specification turns technical committee, offer following opinions, ask each unit comply with to carry out.

One, " boiler pressure vessel uses board " (GB713-2008) carry out transfer period arrangement

(one) unit of pressure vessel design came on September 1, 2008 GB6654-1996 can be used at the same time during December 31 (contain modification sheet) undertake with the material of GB713-2008 pressure vessel is designed. GB6654-1996 must not be used since January 1, 2009 (contain modification sheet) formulary material.

(2) production unit of boiler pressure vessel came on September 1, 2008 GB713-1997, GB6654-1996 can be used at the same time during August 31, 2009 (contain modification sheet) undertake with the material of GB713-2008 boiler pressure vessel is made. GB713-1997 and GB6654-1996 must not be used since September 1, 2009 (contain modification sheet) formulary material.

(3) when the 14Cr1MoR in choosing GB713-2008 and 12Cr2Mo1R material make boiler pressure vessel, the solderer that before GB713-2008 is carried out, undertakes takes an exam and solder inside the range that craft assess can cover in its effective still; When choosing GB713-2008 other data to make boiler pressure vessel, by GB713-1997 and GB6654-1996 (contain modification sheet) in the solderer that lists a brand to undertake takes an exam and solder craft assess, the new name of correspondence of the place in GB713-2008 appendix A still is applied to inside the range that can cover in its, each answer to finish welder before August 31, 2009 about the unit art the changeover that the relevant document such as assess uses new material brand to represent a means works.

(4) when the material in choosing GB713-2008 designs production boiler pressure vessel, fall with use condition in identical norms, design parameter is mixed related its make examine ask to answer the relevant provision of the old name of correspondence of the place in A of basis GB713-2008 appendix, answer to standardize technical committee to apply for special technology to examine to countrywide boiler pressure vessel otherwise.
