Firefighting High Pressure GRE Pipe

GRE tube is a lightweight, high strength, corrosion resistant non-metallic tube. According to the relevant technical requirements, the glass fiber infiltrated in the resin is wound on the core mold. After curing and demoulding, the finished product is obtained. GRE pipe wall structure is reasonable and advanced, under the premise of satisfying the use strength, can give full play to the role of the material, improve the steel degree, ensure the stability and reliability of the product.

Specifications:

T thread joint pipe: T thread and ring bell joint

Nominal dimension: 10" -12”(DN250- DN300)

Pressure rating: 1.6-10MPa

Physical performances of amine cured pipe：

Products technology guarantee:

The production line is mainly controlled by the computer that controls the glass fiber winding process. Control parameters are winding Angle, winding speed, mode conversion, etc.The program is programmed by each winding programmer.

The use of domestic advanced raw materials and formulations can effectively improve the structural integrity of products.

Quality control testing

The axial and circumferential load resistance of the finished product are tested in accordance with the prescribed procedures. All pipelines must undergo the following inspection items: appearance inspection, Barcol hardness, wall thickness, length and inner diameter.

FAQ:

Q: What information do you need before beginning products design?

A: We need design pressure ( static or circulation), design temperature, above ground or underground and etc.

Q: How do GRE products make?

A: GRE pipe and fittings are all manufactured by filament winding.

Typical case:

In the Qinghai Oilfield project in 2003, the pipe specification was DN100 20MPa, and the connection method was threaded connection.
