Product Description:


API Hot Spring Pipe 
1.Standard:API,ASTM,ISO,GB, etc 
2.Anti-corrosion & high strength 
3.Long service time 
4.Low costs

GRE (Glass Reinforced Epoxy)

Some times, GRE and FRP/GRP (Fiber/Glass Reinforced Plastic) are regarded as the same

material with different names, but in most cases, since GRE choice epoxy resin as material, 

it has stronger performances.


It is the thermosetting plastic products combining the reinforced material of fiberglass roving with the base material of epoxy resin
It is made by mechanical filament wound process controlled by computer. 
So it is a kind of composite material. 


The GRE pipe offers a unique combination of chemical resistance, size stability, high strength, and thermal/electric non-conductivity.

So the GRE pipe can be used in the fields of chemical anti-corrosion, construction, electric insulation, power development etc.



1. Anti corrosion

2. High strength, more safety

3. More than 30 years service life

4. Light weight, easy installation and keeping cost

5. Flexible design and shorter reform term

6. No medium pollution

Q:How to repair and repair the broken hole of GRE glass fiber reinforced plastic pipe?
The service will be restored in 24 hours, and I hope this will help you! Can private letter to contact is not clear!
Q:The outer thermal protection layer of the pipeline is made of GFRP. Which guy knows the construction method?
The basic thing is to finish the heat preservation. Soak the PP cloth soaked in the solution and finish it. Then brush it one or two times. The key is to make the solution, with water heating method, or else not. If you want to strengthen the strength, you can finish the insulation, and then wrapped a layer of 10---20 purpose wire mesh, and then made glass fiber reinforced plastic
Q:What qualifications do FRP pipes need to export to Australia?
Need to comply with the local certification standards or international certification standards certification system
Q:The role of glass fiber reinforced plastic cooling towers
Central air conditioning also has cooling tower function is to play the role of cooling circulation.
Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?
Advantages of HDPE tubes:1. It is easy to form the closed anti-seepage system by butt welding and electrofusion welding. When laying along the trench, the excavation of the trench can be reduced and the amount of the fittings can be reduced.2 、 light weight and easy to install;3 、 strong abrasion resistance and excellent hydraulic performance, the buried pipeline can be protected without outer layer. The utility model can be applied to the earthquake and the soil subsidence area of the mining area, and can be laid on the bottom of the river by immersion method.4 、 chemical resistance, resistance to internal, external and microbiological corrosion, corrosion resistance, and health. The utility model is suitable for conveying acid and alkaline substances, conveying sewage, natural gas, gas and other substances;5, good environmental adaptability and frost resistance. It can be used in indoor and outdoor water supply pipelines.6, long service life, with more than almost 50 years of service life;7, easy to recycle
Q:What are the standards for FRP pipes?
As the glass tube between the use of double "O" type sealing ring way to connect, so each installation of a pipe, at the socket to suppress, in order to detect double "O" type sealing ring sealing effect.
Q:What are FRP pipes made of?
The wall of the pipe is smoothReduce flow resistance, increase flow speed and reduce energy consumption. Compared with the same size steel pipe, the flow rate of the same volume can be increased by about 10%, and no fouling and long-term use can not reduce the flow rate. The protection of cables in interference and heavy corrosion environment is better.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
It is a resin based glass fiber weight layer wound on the mandrel rotating on according to process requirements, and distance evenly between the fibers as Kamiishi Eisa in the sand layer.
Q:What are the main points for the installation of FRP ducts?
Underground parking, commercial and residential buildings, shopping malls, civil air defense projects, office buildings and so on
Q:Do I need CCC certification for ventilated GRP?
Usually fiberglass, air conditioning, ventilation pipes will have insulation requirements, the general need not heat preservation.
