GRE Pipework
Benefits
※Long Service Life
Pipes are designed in compliance with the international standards to serve a minimum of 50 years. Operating and maintenance costs are negligibly small. .
※Safe Connections
GRP pipe joints are designed with the flexible connection method, and the sealing is provided by couplings having full-face integrated elastomeric seal.
※Surge Pressure Absorption
Additional pressure increases occurring due to surges are far less when compared with metal pipes. They are designed to absorb 40% of the surge pressure, without increasing the pressure class.
GRE Pipework
The FRP pipe produced by GRAD group is divided into two types: Fiber wind FRP craft tube and Fiber wind FRP nip pipe.Fiber wind FRP pipe is the main product which develops the market successful, it mainly uses in the petroleum, the chemical industry,the electric power,the medicine area and so on. It has the advantage of light weight, high intensity the installing is very convenient.The fiber wind FRP nip pipe is the GRAD group after manufacturing many years successfully and the technical research and development to great today’s result. It is the representative of the reliability ,security and economy, mainly uses in buried the tube and long transport pipeline. It has the advantage of light weight corrosion resistance,long life service,the circulating and the service cost are low and so on may suggest the project serves lots of fee.
FRP winding pipe characteristics
1. Excellent physics mechanics characteristics
The density of the FRP tube material is 1.8-2.1g/cm3.It is about 25 percent of the steel. The density is higher than rolled steel , cast iron and plastic. The weight of the FRP tube is not more than 33 percent of the same specification steel tube, The physics mechanics characteristics. The FRP tube’s heat expanding modulus is almost the same as the steel. The heat exchange modulus is 0.5% of the steel. It is a good insulation material of heat and electricity.
2. Anti chemistry eroding, The using lifespan is longer
The FRP tube has the special characteristic of anti chemistry eroding, under the star studded condition of the tube. It depends on the request of the medium to choose the different anti eroding tube. As for the vertical burying FRP filling voile tube the lifespan must be more than 40 years.
3. Hydraulics characteristics
Excellent Hydraulics characteristics mean that a smaller pipe diameter or a smaller power delivery pump can be selected, so as to reduce the initial investment of pipeline engineering, save electricity and reduce operating costs
4. Low fee of installing and maintenance
The FRP tube doesn’t need special antisepticise disposal, heat preservation can reduce thinness, the pipeline is light, little suspending equipment tonnage, consume little power, long single FRP pipeline, few tie-in on the scene, so the construction is convenient.
5. Unpolluted medium
The FRP pipeline’s density is higher, no impurity peel off and shed, no cauterization, without microorganism and bacteria, so it will not bring any pollution to the transporting material.
