FRP pipe is made of resin as matrix and glass fiber as reinforcement material through special process. This kind of pipeline has the advantages of corrosion resistance, leakage resistance, heat insulation, light weight, high strength, maintenance-free, long service life, strong designability, small fluid resistance, convenient installation and low comprehensive cost. It can be widely used in petroleum, chemical, pharmaceutical, electric power, paper making, urban water supply and drainage, factory sewage treatment, seawater desalination, gas transmission, mining and other industries. It is an ideal pipeline for conveying liquid and gas. In order to ensure the product quality, which international standard does GRP pipe implement? How long is its service life?

1、 The international standards for FRP pipes are as follows:

1. GRP pipe and pipe fittings: HG/T21633-1991;

2. Design regulation for FRP/PVC composite pipe: HG20520-92;

3. Filament wound reinforced thermosetting resin pressure pipe: JC552-94;

4. Glass fiber reinforced plastic sand pipe: GB/T21238-2007;

5. Glass fiber reinforced plastic pipe jacking: GB/T21492-2008;

6. Code for structural design of buried glass fiber reinforced plastic sand pipe in water supply and drainage engineering: CECS190:2005.

2、 Relevant test method standards for GRP pipes:

1. Pressure test method for short time hydraulic failure of fiber reinforced thermosetting plastic pipes: GB/T 5349;

2. Test method for axial tensile properties of fiber reinforced thermosetting plastics pipes: GB/T 5349;

3. Test method for external load performance of parallel plates of fiber reinforced thermosetting plastics pipes: GB/T 5349.

Generally, according to the requirements, the service life of the pipe body is 20-50 years.
