4.1 The pipe door shall be selected, manufactured, tested and accepted in accordance with ZG94004 and this standard T
Reference quantity
4.2 The pipe mouth shall not have delamination, cracks, non-metallic inclusions and other defects that can reduce the strength of the pipe mouth and affect the quality of the glass. 4.3 b in the table is the minimum thickness of the pipe mouth. When making, it must match the thickness of the corresponding top hole and interface to ensure the quality of the butt weld. 5: Packaging, transportation and storage
5.1 The surface of the glass must be prevented from collision to ensure the requirements of the opposite side of the glass. 5.2 The product should be accompanied by a packaging list, Product certificate and product instructions, 5.3 Products should be stored indoors, open-air storage or stacking is not allowed, additional notes:
This standard is proposed by Zhongsui Chemical Equipment Corporation. This standard is under the jurisdiction of the National Standardization Technical Committee for Glass Equipment. This standard was drafted by the Shanghai Pharmaceutical Design Institute of the State Drug Administration. The main drafters of this standard are Hua Qiuyuan, Li Yijun and Bao Aiyuan. This standard refers to the German national standard DIN28159-1983 "Pipes for Glass Containers". From the date of implementation of this standard, the former Ministry of Chemical Industry's standard HG5-261~79 "Pipes for Glass Equipment" will be invalid.
