FAQ of FRP  Pipe

Q: What is fiberglass composite?

A: Fiberglass composite is a laminate made from glass fibers or filaments and thermosetting resin. It is commonly known as RTRP, RTMP, FRP, GRP, GRE and GRV.

Q: Are fiberglass pipes fragile?

A: Due to the elastic nature of the resin which holds the clothlike glass fibers together, fiberglass is strong and flexible. FPI products meet the rigorous "Impact Test" requirements of the international standard e.g. BS, API, ...

Q:What are the differences between FRP pipes and sand pipes in their uses?
Glass fiber reinforced plastic sand pipe is mainly used for conveying medium and low pressure water, raw water and sewage.
Q:Underground garage inorganic glass fiber reinforced plastic wind pipe water out of the way?
Condensate water leaking from the interface of the pipe flange: when the pipe carries the airflow, it condenses the water molecules in the air and is concentrated at the lower part of the pipe due to speed, compression and other reasons. When the flange facing the gap is encountered at the low point, it will leak out of the pipe.
Q:Which is better, PVC pipe and GRP pipe?!
Depends on location, and design requirements. Nowadays FRP is in the majority.
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
When the length and width of glass fiber mesh are not enough, the method of lap joint must be adopted to improve the tangential bearing capacity of the joint, so as to effectively overcome the radial tensile stress, bending force and bending shear stress. The lap length of the glass fiber cloth at the joint is generally 50 to 100mm, and the joint of each glass fiber cloth should be at a certain distance from the adjacent joint. The longitudinal and transverse joints between adjacent layers shall be greater than 300mm, and the distance from the same seam shall not be less than 500mm.5) paste made of circular duct, glass cloth along the radial 45 degree angle to the direction of cut cloth; conical paste products, according to the fan-shaped cloth.
Q:Are FRP pipes still developing?
Although high-end composites have all sorts of benefits, glass tubes can replace traditional plumbing materials, at least far away.
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:How can I replace the valve on the water supply pipe?
Steel flanges, three way pipe fittings and single disk connector is connected, immediately install three branch pipe valve, and will be closed fittings and valves at the bottom with concrete pier support, in order to timely restoration of water supply.
Q:What's the process of continuous winding glass fiber reinforced plastic sand pipe?
In the continuous output of the mold, the resin, chopped fiber and quartz sand according to certain requirements, the use of circumferential winding method of continuous laying, and after curing cut into a certain length of pipe products a method. The equipment has the advantages of convenient process control, low labor intensity, little pollution, good working environment, high production efficiency and stable quality of pipe material.
Q:What kind of epoxy resin and formula do you need for making fiberglass pipe?
By explaining the materials, tools, moulds, renovation and repair, process, structure and various products, the latest development direction, process technology and application of FRP products are described.
Q:How to connect glass fiber reinforced plastic sand pipe?
The overall pressure test shall be carried out with reference to the code for construction and acceptance of water supply and drainage engineering pipes (GB50268-97), with a length of not exceeding 1000m for one section. Double "O" type sealing ring connection can bear the small foundation settlement change, this is the most prominent feature. Docking can be used for ground pipeline installation, can also be used to connect the underground pipeline of individual short, if more construction can meet the requirements of pipeline connection, some information that this connection is a flat end of life, is the use of epoxy resin and glass fiber cloth paste paste, the specific operation method is: first brush the connecting part in the pipeline for a layer of epoxy resin after pasting a layer of glass fiber cloth, flat interface paste length is generally about 500 mm, usually labeled with 5~6 paste layer layer is more solid, each layer of paste paste thickness should not be too large to be a layer of initial setting after a layer of paste. Flange connection line rigid connection, mainly used for connecting glass steel pipe and cast iron pipe, valves and other accessories, often used by glass steel bell and spigot size design, processing special steel bell and spigot connection.
