Features & Benefits of GRP FRP Equal Tees 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 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:The role of glass fiber reinforced plastic cooling towers
Is specializing in the production of glass steel cooling tower, cooling tower, cooling tower, commonly known as cooling tower, glass tower, tower, main square, round, crossflow and counterflow, no filler spray cooling tower series.
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:What are the standards for FRP pipes?
The pressure test pump passes directly through the test hole on the top of the pipe. The water pressure of the pipeline working pressure of 1.5 times after the pump stops (during the operation to open the drain valve exhaust), observation of 2min, the pressure drop value does not exceed the test pressure and the nozzle 5%, no leakage, nozzle pressure test is qualified. If the pressure drop is relatively fast, it shows the sealing effect is not good, to re install, to ensure that the FRP pipe pressure test system overall success.
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:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
1) first, apply the release agent on the molding surface of the glass lined sand pipe mold (or a transparent cellophane on the outer surface of the mold);2) after sufficient drying, the magnesium oxychloride cement with initiator (or curing agent), accelerant and other additives is evenly coated on the molding surface of the die;3) then put a good glass cloth on the glass lined sand pipe;4) then apply the magnesium oxychloride cement on the paved glass cloth and take care to remove the bubbles.5) with good magnesium oxychloride cement paste then with cut glass cloth;6) repeat this operation until the GRP sand pipe reaches the design and gauge thickness.
Q:What kind of material does glass steel ship honeycomb board use?
Analysis of glass steel tube and glass steel tube cellular communication used in communication network construction, is currently used PVC bellows and PVC honeycomb tube, pipe and pipe crossing is the use of plastic pipe or galvanized steel pipe.
Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
Relative to the iron and steel materials such as glass, steel price is the highest, and can reach more than 25 years of life in the outdoors; other materials, such as: PP material, although very similar characteristics of steel and glass, but there is a fatal flaw: the outside is very easy to be corroded and aging, especially direct sunlight high and low temperature conditions, the service life is often less than two years.
Q:What epoxy resin is used for anticorrosion of pipeline glass fiber reinforced plastics?
General glass fiber reinforced plastic, no corrosion protection.If buried with epoxy coal pitch can be, anti rust grade Sa2.5, six oil four cloth can.
Q:Is the installation of FRP pipes required qualification?
Generally speaking, the glass steel pipe manufacturers will be installed for shipyard workers training, but if the shipyard did not ask, the training goal is to allow workers to master the skills to install, but they do not grant workers qualification certificate, but some shipyard will require workers engaged in installation with the installation qualification, so manufacturers will end in training workers to master confirmation the installation skills of workers, awarded the class approved qualification certificate. I don't know. Are you clear about that?.
Q:How can I make up the broken glass fiber?
If the glass fiber reinforced plastic pipe is broken, how do you fix it and repair it better?. It's better to replace it. I wonder how much pressure you use for fiberglass pipes. The proposal is to replace the pipeline.
