W Notice
According to the spirit of the notice on standardizing the use of standard codes issued by the State Bureau of Petroleum and Chemical Industry, the State Administration of Quality and Technical Supervision and the Ministry of Construction, after rectification, the original HGJ515-87 standard number was converted to HG/T21636-1987. All standard numbers "HGJ515-87\" appearing in this standard should be understood to have been converted to "HG/T 21636-1987\, that is, the original standard number BGJ515-87 has been cancelled and replaced by the new standard number HG/T21636-1987. All users and relevant personnel are requested to comply with this. 7 Notice!

1.1 This standard is based on the domestic research results and production practice of glass/polyvinyl chloride (FRP/PVC) composite pipes, and is compiled with reference to the Federal Republic of Germany Standard DIN1896616968,8063.1.2 FRP/PVC composite pipes have the characteristics of PVC pipes in terms of corrosion resistance and alkaline media corrosion resistance, and overcome the disadvantage of PVC pipes in terms of low compressive strength under temperature conditions. PVC pipe only plays the role of medium corrosion resistance, and the compressive strength is completely borne by the FRP reinforcement layer.
1.3FRP-PVC composite pipe is a layer of FRP added outside the PVC pipe. Due to the interface between the two, the adhesive makes FRP and PVC firmly form a whole. It can withstand a certain working pressure under the condition of <80°C. The working pressure of FRP/PVC composite pipes and pipe fittings in this standard under normal temperature conditions is 16~~4kgf/cm2 (gauge pressure). 1.4 According to the thermal distortion performance of the resin, the allowable working pressure of FRP/PVC composite pipes and the change of medium temperature are shown in the following table:
Nominal diameter
65~150
200~300
350~600
The allowable working pressure P of FRP/PVC composite pipes at the following temperatures (-C) is kgt/en20
Note that the allowable working pressure value is obtained by internal drawing method. 66
