•Hydraulic characteristics essentially constant over time

Light weight

(1/4 weight of ductile iron; 1/10 weight of concrete)

•Low transport costs (nestable)

•Eliminates need for expensive pipe handling equipment

Long standard lengths

(6, 12 metres)

Fewer joints reduce installation time

More pipe per transport vehicle means lower delivery costs

Extremely smooth bore

Low friction loss means less pumping energy needed and lower operating costs

Minimum slime build-up can help lower cleaning costs

Precision sealability

With elastomeric rubber rings

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 Flange Adaptor 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:Can FRP pipes be used in heating pipes?
FRP pipes are generally not used in heating pipes, because the use temperature of FRP pipes is limited, as detailed below:1. universal unsaturated polyester FRP can only be used for less than or equal to 60 degrees (HG/T20696-1999)2. bisphenol A unsaturated polyester FRP can only be used for less than or equal to 100 degrees HG/T20696-1999)3. vinyl unsaturated polyester glass fiber can only be used for less than or equal to 120 degrees HG/T20696-1999)4. epoxy FRP can be used for less than or equal to 90 degrees HG/T20696-1999)5. glass fiber reinforced plastic sand holding pipes can only be used for less than or equal to 50 degrees (GB/T21238-2007)
Q:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?
Fiberglass pipeacid: organic resin and glass fiber cloth hand pasting a small proportion of strength and long life advantages
Q:What kind of material are the flanges and valves on the GRP pipe?
It's better to use plastic or polyurethane
Q:The difference between FRP process tubes and GRP tubes
Pure glass fiber reinforced plastic pipe relative to sand pipe prices higher, in addition, the two types of pipe applications in general have obvious differences, process tubes are used in chemical plants and other places, sand pipes are used in municipal.
Q:Slurry circulation glass fiber reinforced plastic pipe
The slurry circulation glass fiber reinforced plastic pipe has good heat resistance and frost resistance. It can be used in the range of 40 to 80 degrees for a long time. If the resin is specially formulated, it can work at temperatures above 110 degrees celsius.
Q:What are the standards for FRP pipes?
In order to comprehensively check the installation quality of the pipeline, it is necessary to carry out a comprehensive examination according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipeline works and to carry out the water pressure test. Permissible water seepage can be carried out according to the standard of FRP pipe.
Q:What are the disadvantages of glass fiber reinforced sand pipe?
Glass reinforced plastic sand pipe is mainly to increase the rigidity of the pipe, the relative wall thickness of pure glass steel tube, low compressive strength, shock resistance decreased.
Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?
If the thickness of the pipe can meet the requirements of pressure, but can not meet the stiffness requirement, will choose to increase the thickness of sand to meet the stiffness (of course can not directly increase the sand thickness to meet the requirement of stiffness, but the cost is too high).
Q:What are the differences between FRP pipes and sand pipes in their uses?
Pressure more than 10 kg, generally do not clamp sand tube. Process tubes are mainly used in highly corrosive workplaces such as acids, alkalis, salt solutions, or high pressure pipes.
Q:Glass fiber reinforced plastic pipeline to do anti-corrosion?
Glass fiber reinforced plastic itself belongs to a kind of anticorrosive material, and usually needs no antiseptic treatment. However, mainly depends on the environment and requirements.
