Control Testing of GRP pipe sea water pipe series

Raw Materials

Raw materials are delivered with vendor certification demonstrating their compliance with Zhongfu Lianzhong quality requirements. In addition, all raw materials are sample tested prior to their use. These tests ensure that the pipe materials comply with the specifications as stated

Physical Properties

The manufactured pipe’s hoop and axial load capacities are verified on a routine basis. In addition, pipe construction and composition are confirmed.

Finished Pipe

All pipes are subjected to the following control checks:

• Visual inspection

• Barcol hardness

• Wall thickness

• Section length

• Diameter

• Hydrostatic leak tightness test to 1.5 rated pressure (only PN6 and above)

On a sampling basis, the following control checks are performed:

Pipe stiffness

Deflection without damage or structural failure

Axial and circumferential tensile load capacity

UnloadingHandlingTransportation and Storage of GRP pipe sea water pipe series

Unloading and Handling Pipes

Unloading the pipe is the responsibility of the customer. Be sure to maintain control of the pipe during unloading. Guide ropes attached to pipes or packages will enable easy manual control when lifting and handling. Do not drop, impact, or bump the pipe, particularly at pipe ends.

If at any time during handling or installation of the pipe, any damage such as a gouge, crack or facture occurs, the pipe should be repaired before the section is installed.

Transporting Pipes

Strap pipe to the vehicle over the support points using pliable straps or rope. Never use steel cables or chains without adequate padding to protect the pipe from abrasion. Bulges, flat areas or other abrupt changes of curvature are not permitted. Transport of pipes outside of these limitations may result in damage to the pipes.

Site Pipe Storage

It is generally advantageous to store pipe on flat timber to facilitate placement and removal of lifting slings

around the pipe.

When storing pipe directly on the ground, be sure that the area is relatively flat and free of rocks and other

potentially damaging debris. Placing the pipe on mounds of backfill material has been found to be an effective

way of site storing the pipe. All pipes should be chocked to prevent rolling in high winds.

Q:The role of glass fiber reinforced plastic cooling towers
Is specializing in the production of glass steel cooling tower, cooling tower, cooling tower, commonly known as cooling tower, glass tower, tower, main square, round, crossflow and counterflow, no filler spray cooling tower series.
Q:How to install FRP pipe correctly
Field bonding process is usually provided by glass fiber reinforced plastic manufacturers, if there is no way, I can provide some experience for reference, there is little information, experience only.
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 are FRP pipes made of?
Length of single pipe lengthReduce pipe connection, speed up installation, improve the quality of the whole pipeline.
Q:Are there any differences between FRP pipes and FRP pipes?
The mechanism glass magnesium composite pipe is made of glass cloth, magnesium and earth, which is hard to burn. The glass fiber reinforced plastic pipe is made of glass cloth and resin, and it is inflammable and light in weight.
Q:What's the process of continuous winding glass fiber reinforced plastic sand pipe?
On line inspection: the pipe being cut and grinded is delivered to the water pressure test machine through the conveyor. After the test is qualified, the pipe joint which has been tested by hydraulic pressure is sent to the pipe joint installation machine for joint installation.
Q:What are FRP pipes used for making? What raw materials?
Reinforced plastic made of glass fiber or its products as reinforcing material. Entitled "glass fiber reinforced plastics" or "glass fiber reinforced plastics". Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. Glass has a hard and brittle, has a good transparency and high temperature resistance, corrosion resistance and other properties; at the same time, steel is very hard and not brittle, but also has high temperature resistance characteristics.
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:Why more and more people choose FRP pipe?
The cost performance of FRP pipes is higher than that of PP, PVC, PE or concrete, and the strength, hardness and toughness of PP, PE and PVC are not as good as those of FRP pipes
Q:What is the compressive strength of all kinds of FRP materials?
Heat resistance, frost resistance: at -30 DEG C, still has good toughness and high strength, can be used for a long time in the range of -50 DEG C 80 DEG C, the temperature of resin with special formula can be more than 110 DEG C. 4) of light weight, high strength, convenient transportation and installation by fiberglassreinforcedplastic pipe winding fiber production, the proportion of 1.65 - 2, 1 / 4 only of steel, but the glass steel hoop tensile strength is 180 300MPa, the axial tensile strength of 60 150MPa, similar to alloy steel. Therefore, its specific strength (strength / density) is 2-3 times that of alloy steel, so that it can be designed according to different requirements of users to meet all kinds of internal and external pressure requirements of the pipeline. For the same diameter of single FRP tube, only carbon steel (steel plate) 1 / 2.5, 1 / 3.5 of the cast iron pipe, about 1 / 8 of prestressed reinforced concrete pipe, so the transportation is very convenient for installation. The GRP pipe is 12 meters per length, and can be reduced by 2/3 from the concrete pipe. The socket connection mode of the utility model has the advantages of quick and simple installation, low hoisting cost and improved installation speed. 5) small friction resistance, high transport capacity: glass tube wall is very smooth, roughness and friction resistance is very small. The roughness coefficient is 0.0084, while the n value of concrete pipe is 0.014, and the cast iron pipe is 0.013. Therefore, glass fiber reinforced plastic pipe can significantly reduce the loss of fluid pressure along the course and improve the conveying capacity.
