GRE tube 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.
In glass fiber reinforced plastic products, glass fiber acts as a reinforcing material, a load bearing body, and a provider of mechanical properties. The strength of the winding product mainly depends on the strength of the glass fiber.
Products advantages:
Durable in use and corrosion-resistant: the surface of internal and external can resist many kinds corrosion of chemicals, crude oil,injected water and bacteria.
The solution of pipe system: The whole FRP pipe have different size, pipe joints, pressure rating for choice.
The pipe length is long: usually the length of the standard pipe is 9 meters each, which reduces the number of joints and reduces the installation cost.
Joint type:
Bonding joint application: Underground low pressure pipeline
Locking key joint application: Underground low pressure pipeline
Lamination joint application: Low pressure pipeline connection
Specifications：
API thread joint type: API 8&10
Nominal dimension; 1.5”- 10"
Pressure rating: 3.5- -25MPa
Operating temperature: 65°C or 93°C
Performances compared between ordinary steel pipe and GRE pipe:
Comparison Item
| GRE pipe
| Ordinary Steel Pipe
|
Corrosion Resistance | Good corrosion resistance | Bad corrosion resistance |
Service Life | 20- -30 years (the designed service life is more than 50 years) | 5-10 years (nocathodic protection and preservative) |
Frictional Resistance | Smooth inner wall can reduce the accumulation of paraffin and scale; Low surface friction increase the flow of fluid velocity | The rough inner surface is easy to form scale and paraffin deposition; High surface friction leads to loss of work pressure |
FAQ:
Q: How much would maintenance costs?
A: GRE products usually do not need maintenance after installation. Our products have one year guarantee period, during which any products quality problems will be solved by us for free.
Q: Are your GRE products resistant to UV?
A: UV block treatment shall be carried out on products if customer request.
FAQ:
Q: Can we choose the connection type by ourselves?
A: We recommend consulting with technical personnel to choose the joint type.
Q: What’s the different between pipes cured by anhydride and pipe cured by amine?
A: Pipes cured by anhydride are usually applied in temperature lower than 65℃. And pipes cured by amine are usually applied in temperature higher than 65 ℃.
