Features & Benefits of GRP FRP pipe sea water pipe series

Corrosion-resistant

•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

Thickness and Weight of Standard Pipes based on Internal Pressure of GRP pipe sea water pipe series

1. Internal liner (thickness 1.0 – 2.0 mm)

   In tables bellow thickness include 1.5mm of liner and minimum pipe Stiffness 1250 Pa

2. Mechanical resistant layer in glass filament winding (based on internal pressure)

3. Top coat (0.2 – 0.3mm) . In tables bellow thickness include 0.2mm of top coat

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:What are the posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?
Glass reinforced plastic underground sand pipe has long service life without operation and maintenance, which is the biggest advantage of this product. Since pipe jacking is an underground concealed project, its service life is undoubtedly the very important consideration of decision-makers. The service life of glass fiber reinforced plastic sand pipe jacking is more than 50 years, which is incomparable to the products such as steel pipe, concrete pipe and so on.
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.
Q:What kind of material is the pipe of the pipe that installs the pressure transmitter of GRP conduit? Is it fiberglass or carbon steel?
It is generally assumed that it is made of glass fiber reinforced plastic. The main pipe is made of glass fiber reinforced plastic. The medium is corrosive. Other materials must not be suitable
Q:What can be done to solve the leakage of FRP pipe?
If you can't get into the pipe, polish it from the outside and polish it to the lining. Then make a new lining, and then use a cloth to reinforce the structure.
Q:How to open a DN300 port on the DN600 GRP pipe and install the DN300 gate?!
Glass fiber reinforced plastic words, such as what you said, for ordinary construction workers, a little difficult, after all, opening and bonding can not do under high pressure or long-term use of water leakage.
Q:Mending method for glass fiber reinforced plastic pipe
Other repair methods: choose resin, accelerator, curing agent, high quality glass fiber cloth. Don't let the powder go. It is autumn, the temperature is low, so to put more than summer curing agent, the proportion of the curing agent, accelerator, resin; 1:1.5:8 with glass fiber wrapped around the pipe, coated on the glass fiber cloth for glass steel with a good quick, let the glass steel glass fiber cloth fully soaked, waiting for glass steel fully cured, and then repeated several layers. It will be strong.
Q:Excuse me, what standard does the glass fiber that check mechanical and electrical use accord with GB?
FRP insulated pipe is a kind of light, high strength and corrosion resistant nonmetal pipe.
Q:Pipe installation of glass fibre reinforced plastic pipe
The slope of the pipeline shall be adjusted according to the requirements of the drawing. The adjustment method can be achieved by using the support to reach the slope requirement. The weld shall be located where it is convenient for inspection and observation.
Q:Underground garage inorganic glass fiber reinforced plastic wind pipe water out of the way?
The condensed water duct wall: when the fan start, rapid air circulation in the inorganic pipeline flow, pipeline internal and external space of large temperature difference, leading to the underground garage of the water vapor condenses into water droplets freeze in the outer wall of the pipe. At this point, on the surface, it seems to seep through an inorganic pipe;
Q:What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Oil and gas pipelines used for twenty years, basically no corrosion phenomenon. As part of a group of coal tar epoxy primer and topcoat are based on epoxy resin and coal tar as the main film-forming material, add a variety of anti rust paint, insulating filler, toughening agent, leveling agent, diluent, anti settling agents and other materials, the B component is modified amine curing agent or curing agent the main material, adding fillers. When the product is sold, the A and B parts are supplied together, and the mixture is mixed in proportion during construction.
