follows.
- Added diameters between DN 6100 ~ DN 13200;
- For the nominal diameters between DN 6100 ~ DN 13200, a diameter
grade is defined for each 100 mm increment;
- Adjusted outer diameter for DN 150, DN 350, DN 400 pipes which take
outer diameter as the reference.
This Standard was proposed by and shall be under the jurisdiction of National
Technical Committee on Boiler Pressure Vessels of Standardization
Administration of China (SAC/TC 262).
The drafting organizations of this Standard. China Petrochemical Engineering
Construction Co., Ltd., China Special Equipment Inspection and Research
