High Pressure GRE Pipe

Brief Introduction:

GRE pipes are made of glass fiber roving as reinforcement, epoxy resin as the matrix material, molded by winding. High Pressure GRE pipes are GRE pipes whose working pressure is above 1000PSI to API 15HR.

There are some merits of GRE pipes listed below:

1.Light weight, easy installation and transportation;

2.High strength Ratio and perfect mechanical properties;

3.Good anti-corrosion performance;

4.Low thermal conductivity and low thermal stress;

5.Good electric insulation performance;

6.Good hydraulics performance;

7.Never get rusted, posing no secondary contamination to the transported media;

8.Anti-contamination and resistance to insects; good wear resistance and high design ability.

GRELine pipe serial serves as a solution with comprehensive competitiveness for many customers. The GRE Line pipe can be designed and manufactured as per customer demand.
