Description of GRP Fittings

GRP or FRP pipework is manufactured in accordance with BS 7159, with structural, chemical and thermal properties being dictated by the type of resin selected by Plastichem specialists.
GRE pipe systems with filiament wound construction provide higher mechanical strength with lower cost.

The most common resin type specified is a Vinylester Epoxy which has excellent chemical resistance to a broad range of chemicals. 
Plastichem design experts can offer stress analysis on all GRP pipework. Stresses are reduced where necessary by increasing laminate thicknesses, increasing leg lengths and adjusting support distances and clamp positions.
The internal corrosion barrier can be varied to suit the application and abrasion resistant GRP linings are also available for flue gas slurry handling. 
Manufacture of the pipe is by mandrell winding of chopped strand glass fibre or by filament winding. Elbow and tee fittings are moulded and then joined to the pipe where required.

One of the benefits of this system is that sections can be pre-fabricated in the factory and then site joined. This method minimises site work and elliminates flanged joint connections. 
GRP piping can be coloured externally for line identification, UV and fire resistant properties can be enhanced with additional resin coats.

FAQ

1, How to choose the pipe materials of GRP?

Generally speaking, the choice of RPMP should consider the groundsill and soil of RPMP. When the design of pipeline has the full reconnaissance design, geology situation, and hydrology situation, we should choose according to the AWWA-C950 standard. For the using factories, they can supply such data to the manufacturer, and the manufacturer can carry out the design and produce the qualified pipe materials according to the buyers’ demand.

 

2, The notice of ordering to the GRP pipes?

General booker should define the following questions including using condition:

1). The structure length of the fixed length RPMP is 1.2m. However, in the real lay project, the spigot and socket joint is adopted, the pipe’s using quantity should be calculated by the pipe’s effective length. Generally speaking, the effective length of 1.2m fixed length pipe: 300-DN1200 is 11.74m, DN1300-DN1500 is 11.679m and DN1600-DN2600 is 11.613m.

Eg: if we lay the straight pipe section for length 1000m, the quantity of fixed length pipe with effective length 11.74 is 1000m÷11.74m/piece≈85pieces.

2). In order to meet the buyer’s demand, manufacture can produce the unfixed length pipe. Generally speaking, RPMP can produce various pipes of any length (≤12m). But it must consult the manufacturer’s suggestions. Generally speaking, the manufacturer can supply the unfixed length pipes with 3m, 4m, 5m, 6m, 8m, and 12m.

Q:How to repair and repair the broken hole of GRE glass fiber reinforced plastic pipe?
Place an iron or glass piece of steel on a broken hole like a bicycle tire, then use three oil, two cloth, or five oil three cloth;
Q:Slurry circulation glass fiber reinforced plastic pipe
The slurry circulation FRP pipe project has long service life and is safe and reliable. The pipeline is durable and the safety factor is above 6. The pipeline life can reach up to 50 - 100 years. For example, the water supply pipeline from Shenzhen to Hongkong was built on the side of Hongkong, long 50KM, respectively, two kinds of glass pipes with inner diameter, 2.2m and 1.7m, which were installed and used so far in 1965, and they were left intact.
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe? What kind of material is good?
Sand tube is more brittle, gfrpmp is relative to the glass tube can be called pure glass tube, glass tube is not with quartz sand, the two pipes generally used in different areas, the pure glass pipe can be used in most areas, but the sand tube is generally only used in the political field, especially is the large diameter sand tube.
Q:What's the process of continuous winding glass fiber reinforced plastic sand pipe?
(1) die: the continuous flat steel supported by the reel, winding to form a round mandrel.(2) feeding: when the mandrel moves, advanced packing, glass fiber, resin and surface material are accurately placed under the control of program control (PLC) and microcomputer (PC).(3) monitoring: according to the prepared material input program, only the basic pipeline data can be input; the computer can calculate the mechanical operation settings by itself. Material consumption, pipe thickness and so on will be constantly monitored and recorded.(4) curing: induction heating of the curing process of the product is accomplished by the flat band and the infrared device which is directly heated in the product. The temperature of 20 different parts of the product in the curing zone will be measured and displayed in the form of an image on the computer screen.(5) cutting and trimming: the pipe can be cut from 0.3 meters to 18 meters under the predetermined length. The cutting, chamfering and caliber measurement are coordinated with the longitudinal movement of the product to ensure the accurate vertical cutting of the glass fibre reinforced plastic pipe and the killing of the outer diameter.
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: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:Glass fiber reinforced plastic pipeline to do anti-corrosion?
Glass steel pipe does not need to do anti-corrosion treatment, the material itself is the biggest advantage of corrosion resistance
Q:How much is a glass fiber reinforced plastic sand pipe socket pipe fitting?
Glass reinforced plastic sand pipe can increase rigidity by adding sand layer to the middle layer of pipe wall, which can meet any reasonable rigidity requirement of users. Another advantage of gfrpmp stiffness is bending deformation ability is very strong, for example, glass steel 5000Pa stiffness of sand in deformation of 20% cases, no delamination damage, and after unloading can restore the concrete pipe due to large deformation may be unable to bear have broken gfrpmp ring 150MPa ~ to the apparent flexural strength 450MPa, tensile and compressive and flexural strength of the concrete pipe were borne by steel and concrete, the apparent flexural strength is still far below the gfrpmp, only 8.5% ~ gfrpmp 26%. Generally, the service life of the drained glass fiber reinforced plastic sand pipe can be more than 50 years, and it is more than 2 times that of reinforced concrete pipes and other drainage pipes.
Q:Which is better, pultruded FRP square pipe with PVC?
When a strong corrosive gas, liquid or solid is conveyed in a wear-resistant pipe, there is a problem that the abrasion resistant pipeline is corroded and soon destroyed.
Q:How can I make up the broken glass fiber?
If you have to repair it, it is not impossible. Resin selection of good points, the general also line, as well as accelerators, curing agents, high-quality glass fiber cloth.
