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:Pipe installation of glass fibre reinforced plastic pipe
In response to the pipeline before installation equipment nozzle, embedded parts, reserved holes and steel structure relates to the pipeline installation content review.
Q:What are the functions of glass fiber reinforced plastics?
Because FRP is a kind of composite material, its performance range is very extensive, so its market development prospect is very broad. According to statistics, the types of FRP products developed in various countries in the world have reached about 40 thousand kinds. Although all countries are in accordance with their own economic development, the direction of development has its own focus, but basically all sectors of the industry have been involved. After more than forty years of development, the glass fiber reinforced plastic industry in our country has been successfully applied in all fields of national economy, and has played an important role in economic construction.
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?
This data mainly explains glass fiber reinforced plastics and other glass fiber reinforced materials manual forming process and all kinds of products.
Q:The difference between FRP process tubes and GRP tubes
Kashi Eisa's goal is to increase stiffness (large pipe defects) and reduce costs, and process tubes (mostly small tubes), these two aspects are no problems;
Q:What is the compressive strength of all kinds of FRP materials?
Anti fouling and anti moth: unsaturated polyester resin surface clean and smooth, will not be ocean or sewage in the shellfish, fungi and other microorganisms stained, moth, so as to increase roughness, reduce water cross section, increase maintenance costs. FRP pipes are free from these pollution and are clean for a long time. At the same time, because of its smooth inner wall and excellent corrosion resistance, it will not cause scale and microbial growth, effectively guarantee water quality and maintain the stability of water resistance. But the traditional pipe still exist after water resistance increases and the surface fouling phenomenon.
Q:What are the main materials used for steel pipes?
The ventilation pipe in the industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, industrial pollution control, dust, oil and smoke exhaust pipe, industrial environment or position by giving comfort the wind pipe, coal mine gas drainage system, gas pumping for coal mine environment control air supply system and so on..;
Q:What is the structure and function of glass fiber reinforced plastic lining?
The structure is made up of colloid + glass cloth. The construction process is like this:1, carbon steel inner wall grinding acute angle, rust removal2, brushing glue3, cloth affixed4, brushing glue5, cloth affixed
Q:FRP acceptance standard
As the glass pipe between the use of socket type, double "O" type sealing ring connection, so each installation of a pipe, it is necessary to bear in the socket to suppress, in order to detect double "O" type sealing ring sealing effect. The pressure test pump passes directly through the test hole on the top of the pipe. The water pressure of the pipeline working pressure of 1.5 times after the pump stops (during the operation to open the drain valve exhaust), observation of 2min, the pressure drop value does not exceed the test pressure and the nozzle 5%, no leakage, nozzle pressure test is qualified. If the pressure drop is faster, the sealing effect is poor and needs to be reinstalled to ensure the overall pressure test of the FRP piping system is successful.
Q:What kind of material are the flanges and valves on the GRP pipe?
It's better to use plastic or polyurethane
