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

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
Unloading,Handling,Transportation 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 is the difference between glass tube, sand pipe and glass tube?
- Glass reinforced plastic sand pipe is actually in the production of glass fiber reinforced plastic pipe, in the middle to increase a layer of sand layer, the purpose is to increase the rigidity of the pipeline.
- Q:How to prevent the glass fiber reinforced plastic pipe from being damaged by aging or over pressure, causing the liquid to splash and hurt people
- If you are afraid of the glass tube will be such a question, the weak links or parts of the local reinforcement, the conditions can, can re pipe liner, to compression, anti ageing effect
- Q:Why more and more people choose FRP pipe?
- And the price ratio of FRP pipe is not much cheaper, and although the hardness of concrete pipe although FRP pipe to be hard, but the toughness and tensile strength is poor, the pressure is not good, and the cost is expensive, because more and more people use glass steel, and the price is expensive, with longer life.
- Q:What are the differences between inorganic FRP pipes and plexiglass pipes, what are the advantages and disadvantages?
- Inorganic glass fiber reinforced plastic wind pipe: magnesium magnesite soil and glass fiber mesh cloth made of advantages: flame retardant shortcomings: large proportion, low strength
- 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: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:How is the glass reinforced septic tank and the cement drain pipe connected?
- The interface can be bonded with epoxy resin adhesive. The epoxy resin strongly adhere to the two materials, but the bonding surface must be clean.
- Q:What kind of project needs fiberglass pipe?
- Glass fiber reinforced plastic material has the advantages of corrosion resistance, high strength, low weight, and other materials can not be compared, the use of a wide range of purposes, such as water supply, chemical raw materials, hot and hot water transportation, ventilation and so on
- Q:Characteristics of FRP pipes
- (1) corrosion resistance: chemically inert material, excellent corrosion resistance, and can choose different corrosion resistant pipes according to the transmission medium.(2) strong mechanical strength: good water pressure resistance, good resistance to external pressure and impact strength, and piping and fittings can be designed according to the required pressure.(3) temperature adaptability: the use of temperature range: greater than -70 degrees Celsius, less than 250 degrees Celsius, under the freezing medium, the pipe is not split.(4) the resistance of the fluid is small: the pipe wall is smooth, the roughness coefficient is 0.0084, and the pipe diameter can be reduced under the same flow rate.(5) light weight, long life: light quality, convenient transportation, low construction cost, no maintenance, and the service life of more than 50 years.(6) maintain the water quality: non-toxic, conveying drinking water, can maintain long-term water quality sanitation. The application of FRP: the drinking water distribution pipe and line pipe conveying
