Abstract: This paper briefly introduces the basic connection mode of glass fiber reinforced thermosetting plastic (GRP) pipe, which is non-metallic pipe. The article makes a comprehensive comparison of the domestic and foreign standards and codes related to GRP pipes in petrochemical industry, and suggests that the petrochemical industry should adopt American standards. Focusing on several commonly used interface types of GRP pipe, this paper makes a further analysis of the interface strength, the comprehensive cost and the applicability of geological environment, and gives some suggestions on the connection mode of GRP pipes for water supply and drainage projects in petrochemical industry.

Key words: non-metallic pipe, GRP pipe, connection mode
