Structure of GRP Pipe for Sewage:

In the FRP .with high tensile strength, the fiberglass plays the role of reinforcement whiles the wear-resistance and pressure –resistance synthetic resin is used for bonding the fiber as the basic materials. Putting together, they commonly play the role of being in finished form and load carrier.

The wall structure of the FRP pipe is normally consisting of two parts:

Structure layer: make the continuous glass fiber woven of which is cross winded according to the design angle as the reinforcing frame. Make the synthetic resin as the bonding basic materials. Among them, the weight of fiberglass occupied about 65-70% weight of resin about 30-35%. In order to strengthen the structural stiffness, the resin and silicon sand paste could be added in the middle layer of fiberglass filament winding layer.

Inner liner-this is a layer of anti corrosion and leakage proof it is formed by two parts.

   1. Interior surface layer-this is a layer directly contacts the medium and it is corrosion resistance and the first layer of leakage proof. The content of resin in this layer is about 90%.

   2. The second interior layer-it is formed by chopped strand mat reinforcement and anti corrosion resin; the content of the gel coat is above 70% and about 2mm thickness. This is the second protection of anti leakage of the medium.

Application GRP Pipe for Sewage:
Due to its own advantages, the GRP pipes is used extensively in the city engineering water supply and drainage, the water supply and the drainage or the recycle water in the electric factory, the waste water treatment, the oil chemical industry and so on.

 

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: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:What are FRP pipes made of?
Length of single pipe lengthReduce pipe connection, speed up installation, improve the quality of the whole pipeline.
Q:Mending method for glass fiber reinforced plastic pipe
The method for mending and mending the glass fiber reinforced plastic pipe is hand paste, and the repairing steps are as follows:The stones must be taken away so that the pipes are restored to their original shape.Into the pipe, grinding first and lining the lining. If you can't get into the pipe, polish it from the outside, polish it to the lining, and then make a new lining.Reinforce the structure with a cloth.
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
1) FRP reinforcement, length of rectangular duct is greater than 900mm, and the pipe length is more than 1250mm, should be strengthened. The reinforcement shall be made of bulk material (fiber reinforced plastic) and reinforced plate at the maximum stress, so as to increase the modulus of the section and increase the overall strength of the tube. FRP reinforcement can also be in the wind pipe production is completed, the treated metal or other corrosion resistant material for reinforcement, reinforcement and FRP as a whole, and with the same pipeline body cementitious material sealing gap2) hobas pipe surface thickness of the slurry to flatten the glass fiber mesh cloth texture is appropriate (see:). No dense air holes and grout leaks are allowed on the wall of the pipe to avoid the stress concentration under the bending tensile stress (positive air pressure) and the bending compressive stress (negative wind pressure).3) FRP pipe and flange corner should transition arc, transition radius to wall thickness of 0.8 ~ 1.2 times, improve the bearing capacity and the cantilever flange to avoid stress concentration. Fiberglass mesh shall be extended to the duct at the flange of the duct.
Q:What are the functions of glass fiber reinforced plastics?
Glass fiber reinforced plastic (FRP) is a kind of composite material which has been developing rapidly for more than fifty years. 70% of glass fiber output is used to make fiberglass. Glass steel is much harder and much lighter than steel.
Q:Glass fiber reinforced plastic GRE pipe broken hole how to repair and repair?
Don't let the powder go. It is autumn, the temperature is low, so to put more than summer curing agent, as to the exact proportion, I just guess should be: curing agent, accelerator, resin; 1:1.5:8 with glass fiber wrapped around the pipe, coated on the glass fiber cloth to make glass steel with good quickly, let the glass steel the glass fiber cloth fully soaked, waiting for the full glass steel after curing, and then repeated several layers. It will be strong.
Q:What are the advantages of FRP pipes?
The relative density is between 1.5~2.0 and only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel.
Q:What is the thickness of all types of FRP pipes?
The standard effective length of the tube is 6m and 12M, and the production methods include fixed length winding process, centrifugal casting process and continuous winding process of three kinds. Classification can be carried out according to the product process method, pressure grade PN and stiffness grade SN.
Q:What epoxy resin is used for anticorrosion of pipeline glass fiber reinforced plastics?
3PE has some disadvantages. (1) the bending of the guiding hole and the protruding rock, pebble and gravel in the hole will cause friction and scratch to the relatively soft 3PE corrosion resistant layer. (2) 3PE coating using polyethylene heat shrinkable sleeve joint, the convex part of the concave or lap joint, which makes it easy to travel being scratched or pulled off lead. (2) 3PE corrosion protection layer has a strong electrical shielding, so that the cathodic protection current is difficult to reach the defects of corrosion protection layer, thus causing perforation corrosion.So, from the last century at the beginning of 90s, the United States developed Powercrete (s) Powder Concrete Anticorrosion structure, namely in the bottom of fusion bonded epoxy powder, sprayed with epoxy resin as main film-forming material, and adding a two-component epoxy coating for concrete, polymer concrete curing agent and other inorganic fillers. The coating is tough and wearable and can be used directly in FBE coated pipes to protect the pipe from damage during handling, directional drilling, crossing, etc..
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.
