Tight, efficient joints designed for bell & spigot to eliminate infiltration and ex-filtration

Ease of joining, reducing installation time

Accommodates small changes in line direction without fittings or differential settlement

Flexible manufacturing

•Custom diameters can be process manufactured to provide maximum flow volumes with ease of installation for rehabilitation

lining projects

High technology pipe design

•Lower wave celerity than other piping materials can mean less cost when designing for surge and water hammer pressures

High technology pipe manufacturing system producing pipe that complies to stringent performance standards (AWWA, ASTM, DIN, EN, etc.)

•High and consistent product quality worldwide which ensures reliable product performance

Control Testing of GRP FRP Equal Tees 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 FRP Equal Tees Sea Water Pipe Series

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:There is a gap between the new glass fiber reinforced plastic pipe and its through wall. How can the plug be prevented from leaking through the cracks around the pipe?
Foam with polyurethane, and buy their own back, do it yourself.
Q:Is it possible to touch the water when the glass fiber reinforced plastic pipe is polished?
Because the resin curing mechanism of FRP products is resin, resin agent, resin curing agent together to react, and release a lot of heat, this process does not affect the curing process because of a small amount of water and at the same time, if you have a little bit of water molecules would because of the large amount of heat emitted by evaporate, so does not affect the bonding of glass and steel that will not affect the glass steel pipe interface
Q:What are the standards for FRP pipes?
To install FRP pipes, first check the radial deflection of the GRP pipe. In accordance with the requirements of the specification, the FRP pipe shall be tested within 24 hours after the completion of the installation to test whether the initial radial deflection of the pipe installed is deformed and whether the pipe has occurred in the case of bulge, flat and other mutations.
Q:Which is better, PVC pipe and GRP pipe?!
Depends on location, and design requirements. Nowadays FRP is in the majority.
Q:What kind of diamond saw blade for cut glass steel pipe?
It is better to use ceramic stem slice, thin, toothless and wear less.
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 is the elastic modulus of glass fiber reinforced plastic?
Glass fiber reinforced plastics (FRP), also known as GFRP, that is, fiber reinforced plastics, generally refers to the use of glass fiber reinforced unsaturated polyester, epoxy resin and phenolic resin matrix. Reinforced plastics made from glass fiber or its products are called fiberglass reinforced plastics, or "GRP", and they are distinguished from tempered glass. 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. It is light and hard, non conductive, stable in performance, high in mechanical strength, low in recycling and corrosion resistant. It can be used instead of steel to make machine parts, automobiles, ship shells, etc..
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:How to install FRP pipe correctly
Glass tube and carbon steel pipe connection, at present, the most reliable way of connection is indeed onlyOther, such as on-site bonding, because of the two kinds of material is not the same, the quality of bonding is not very stable!
Q:What are the materials used in smoke exhaust pipes?
According to the current national standards: ventilation pipe exhaust pipe material selection of steel pipe (steel), galvanized plate (Bai Tie) smoke pipe, the exhaust pipe exhaust pipe, exhaust pipe, stainless steel pipe, plastic glass smoke exhaust pipe, composite sandwich insulation board, industrial exhaust pipe exhaust exhaust pipe.
