Description of GRP high-pressure pipe

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.
