     1. The preparation method of product model is in accordance with JB 308.

     2. There are four types of single ram, double ram, with or without orifice.

2. Basic standard parameters

     1. The nominal pressure is in accordance with GB 1048.

     2. The nominal pass shall be in accordance with the provisions of GB 1047.

     3. The pressure-temperature rating of steel pipe flanges is in accordance with GB 9131.
