GRE pipe is a lightweight, high strength and corrosion resistant non-metallic pipe. Winding glass fiber which has been immersed in epoxy resin on the core according to technology requirements. After curing and demoulding, finished GRE products is done. Its pipe wall structure is reasonable and advanced, which can give full play to the role of the material, on the premise of meeting the use of strength, improve the degree of steel, to ensure the stability and reliability of the product.

Performances compared between ordinary steel pipe and GRE pipe:
Comparison Item
| GRE pipe
| Ordinary Steel Pipe
|
Service Life | 20 to 30 years(the designed service life is more than 50 years) | 5 to 10 years (no cathodic protection and preservative) |
Insulation Performance | There are no minimum and additional insulation requirements for high temperatures and harsh ambient temperatures | A lot of heat loss under high temperature. |
Maintenance Fees | It almost need no repair | Need anti- corrosive paint, cathodic protection and corrosion monitoring |
Products quality guarantee:
a, The process from raw material inspection, winding process, curing process, process control and monitoring to finished products are in accordance with international standards and quality requirements.
b. The use of domestic advanced raw materials and formulations can effectively improve the structural integrity of products.
Before GRE pipe design, the below questions shall be clarified:
whether need internal liner or not
whether need anti-UV protection External coating layer or not
whether need insulating layer
FAQ:
Q: What is the colour of GRE pipes?
