Features & Benefits of GRP FRP pipe sea water pipe series


•Long, effective service-life materials

•No need for linings, coatings, cathodic protection, wraps or other forms of corrosion protection

•Low maintenance costs

•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 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:How to repair and repair the broken hole of GRE glass fiber reinforced plastic pipe?
Place an iron or glass piece of steel on a broken hole like a bicycle tire, then use three oil, two cloth, or five oil three cloth;
Q:Are FRP pipes still developing?
Glass steel complex (or perhaps not, but not absolutely continuous production mishap) manufacturing process, and China quality is not strictly controlled, low cost of pipeline as well as PVC and other engineering plastics, the high demand of the field of steel as reliable, is now used for chemical terminal treatment, city drainage etc..
Q:Galvanized steel sheet and inorganic glass fibre reinforced plastic pipe are calculated according to this norm or norm
According to the project of quota valuation mode, input the actual quantity according to the quota item number, the following materials will automatically adjust the quota quota project, has been considering material wastage, when engineering calculation does not need additional.
Q:The difference between GRP cable duct and PVC cable pipe
PVC cable pipe refers to various kinds of rigid PVC pipes made of PVC resin as main raw material and various stabilizers.
Q:Why FRP pipe corrosion?
No material was selected. If there is corrosive requirements, it is necessary to use corrosion-resistant materials to make glass fiber reinforced plastic pipe.
Q:What are the functions of glass fiber reinforced plastics?
The jet can reduce the weight of the aircraft by using it as an oil tank and pipe. Astronauts aboard the moon, who carry miniature oxygen bottles on their backs, are also made of glass fiber reinforced plastic. Glass fiber reinforced plastics are easy to process, stainless, and do not need paint. Our country has been widely used in glass steel manufacturing all kinds of small boats, boats, yachts, and automobile manufacturing, save a lot of steel.
Q:Glass fiber reinforced plastic GRE pipe broken hole how to repair and repair?
Don't let the powder go. It is autumn, the temperature is low, so to put more than summer curing agent, as to the exact proportion, I just guess should be: curing agent, accelerator, resin; 1:1.5:8 with glass fiber wrapped around the pipe, coated on the glass fiber cloth to make glass steel with good quickly, let the glass steel the glass fiber cloth fully soaked, waiting for the full glass steel after curing, and then repeated several layers. It will be strong.
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:FRP pipe price
FRP prices are calculated in terms of material length and nozzle diameter.FRP duct price is: 3mm specifications 66 yuan / square meter, 4mm specifications 88 yuan / square meter, 5mm specifications 110 yuan / square meter, 6mm specifications 130 yuan / square meter, 7mm specifications 150 yuan / square meter
Q:Which is better, pultruded FRP square pipe with PVC?
When abrasive materials are transported in the wear-resistant pipes (such as ash, coal dust, ore fines, etc.), there is a problem of rapid wear and tear of the wear-resistant pipes, especially the rapid wear of the bent pipe.
