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 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: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 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:How is FRP ventilation pipe made?
Coating moldingOn the surface of the mold, a transparent glass paper is fixed on the surface of the bread. When it is fixed, it is coated with a resin coating which has been adjusted. It should be even and not exposed. Then apply a layer of glass cloth and then coat with a resin coating. Each coated with a layer of resin is deposited a layer of glass cloth. The cloth lap to stagger and scraping, the outermost layer of ruibu glass surface should be coated with a layer of resin coating. After reaching the required thickness, and then deposited on the outer surface of the glass paper flatten the light pressure.
Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
Glass tube wall thickness is generally determined by the manufacturer design, with stereotypes products and sequences, you can choose according to the pressure level.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
The pipe wall structure reasonable and advanced, can give full play to the role of material, to meet the premise of use strength, improve the rigidity, ensure the stability and reliability of the product. Because of its excellent chemical resistance, light weight, high strength, no scaling and strong seismic resistance, the glass steel sand inclusion has the advantages of long service life, low overall cost, quick installation, safety and reliability compared with ordinary steel tubes.
Q:What are the specifications of glass fibre reinforced plastic cable pipes? What are they?
Strong corrosion resistance, insulation, non magnetic, acid, alkali, flame retardant, anti-static. The utility model has the advantages of good elasticity of bending modulus, complete solution of the corrosion of the metal pipe, no distortion and elasticity, and the defects that the plastic tube is easy to aging and the impact resistance is poor. Good water resistance, can be used in damp or water for a long time without deterioration. Due to the specific properties of glass fiber reinforced plastic, the service life of the glass steel pipe is more than 50 years. The construction is convenient, in particular the repair project, the efficiency is particularly prominent, is the power cable communication cable engineering, municipal engineering and road underground cable is the most ideal protective device, the cable bridge across the river, the use of the most suitable and convenient.
Q:Raw material and mix ratio of inorganic glass fibre reinforced plastic wind pipe
Glass, reinforced with filler, the general ratio is 1 to 0.001
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
When the length and width of glass fiber mesh are not enough, the method of lap joint must be adopted to improve the tangential bearing capacity of the joint, so as to effectively overcome the radial tensile stress, bending force and bending shear stress. The lap length of the glass fiber cloth at the joint is generally 50 to 100mm, and the joint of each glass fiber cloth should be at a certain distance from the adjacent joint. The longitudinal and transverse joints between adjacent layers shall be greater than 300mm, and the distance from the same seam shall not be less than 500mm.5) paste made of circular duct, glass cloth along the radial 45 degree angle to the direction of cut cloth; conical paste products, according to the fan-shaped cloth.
Q:What is the heat preservation of the plumbing pipe now? I'd like to use fiberglass Seek help from a master
The simplest economy is the use of rock wool insulation. A little higher cost is polyurethane foam insulation, and the shell is made of PE yellow jacket. FRP insulation effect should not be too good
Q:How to connect glass fiber reinforced plastic sand pipe?
The quality of the connection of glass reinforced plastic sand pipe pipe directly affects the quality of the pipeline. The connection forms between the pipes include 3 forms: socket, butt joint and flange connection.
