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:Can FRP pipes be used in heating pipes?
Glass steel pipe road does not belong to common heating pipe material.Heating pipe requirements are solid, high temperature, pressure, easy connection, convenient construction.Usually, heating pipes are made of steel and materials are more common.
Q:How can FRP tanks be connected to steel tubes?
FRP pipe and glass fiber reinforced plastic fittings (three passes, elbows, etc.) generally speaking, the best way is on-site bonding, the quality is stable and convenient.
Q:How can I replace the valve on the water supply pipe?
According to the position of the branch pipe, the position of the opening is reasonably determined, and the position of the socket of the glass steel pipe is avoided as far as possible, and a better position is selected in the middle of the pipe body;
Q:Galvanized steel sheet and inorganic glass fibre reinforced plastic pipe are calculated according to this norm or norm
According to the project of quota valuation mode, input the actual quantity according to the quota item number, the following materials will automatically adjust the quota quota project, has been considering material wastage, when engineering calculation does not need additional.
Q:CGCT what's the meaning of the GRP sand pipe?
If the thickness of the pipe can meet the requirements of pressure, but can not meet the stiffness requirement, will choose to increase the thickness of sand to meet the stiffness (of course can not directly increase the sand thickness to meet the requirement of stiffness, but the cost is too high). Sand sandwiched glass fiber reinforced plastic pipes only have more than one sand sandwiched with glass fiber reinforced plastic pipes, and sand layer can be understood to replace glass fiber with quartz sand. The sand pipe with the same thickness is compared with the glass fiber reinforced plastic pipe, but the sand holding pipe is cheap, but the strength is poor; and the glass steel pipe is opposite.
Q:Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
If a glass fiber reinforced plastic outlet pipe is reserved, a new sewage inspection well is installed at the pipe end, and then a sewage pipe is installed to connect the reserved manhole of the municipal sewage pipe.
Q:What kind of project needs fiberglass pipe?
Suitable for high temperature, high corrosion resistance and high pressure conditions, if you are interested can also go to Guangzhou to visit the company Weibo glass steel and understanding
Q:FRP pipe and 0.7 thick galvanized pipe which cost is low?
The best material in glass steel mould rubber production 20 years, customers in all aspects
Q:What is fiberglass communication tube?
Glass fiber reinforced plastic communication tube is a kind of light, high strength, corrosion resistant and burr free metal pipe. It is mainly used for protecting cables and cables.
Q:How to improve the compressive strength of waste glass fiber reinforced plastic profiles (such as square tubes) should be started with resin, curing agent, glass fiber or other aspects!
Ensure the solidification of glass steel products in a reasonable range, in general, glass fibre reinforced epoxy resin material curing degree if the use of amine curing agent, the best curing degree in the range of 135 degrees --150 degrees, polyester resin, Mohs hardness of about 60 is OK.
