Introduction of GRE Pipes for Oil Exploration and Transportation

Lightweight and easy to handle and install, GRE pipes have a smooth internal surface that reduces friction and enables a high pipe flow capacity. The low thermal conductivity of GRE pipes relative to steel (only one percent of steel values) minimises the cost of insulation and heat loss. Another major benefit of GRE pipes is that, once they are installed, they are virtually maintenance-free.
GRE pipes are well suited for environments where corrosion resistance is required at a reasonable price.
Main uses include petrochemical process lines, oil and gas systems, fire-fighting systems, offshore and onshore systems, and ship and marine applications.
GRE pipes are available in diameters ranging from DN 25 to DN 1,000 mm.

GRE Pipe for Oil Exploration and Transportation

Q:Do I need CCC certification for ventilated GRP?: The air duct is made of 10MM thick fiberglass pipe, and the design of the air duct is wrong. The FRP pipe is developed for fire control and smoke exhaust.

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: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:Mending method for glass fiber reinforced plastic pipe: The method for mending and mending the glass fiber reinforced plastic pipe is hand paste, and the repairing steps are as follows:The stones must be taken away so that the pipes are restored to their original shape.Into the pipe, grinding first and lining the lining. If you can't get into the pipe, polish it from the outside, polish it to the lining, and then make a new lining.Reinforce the structure with a cloth.

Q:FRP acceptance standard: Perform hydrostatic test. In order to comprehensively check the installation quality of pipes, the pressure test shall be carried out according to the test methods stipulated in the code for construction and acceptance of water supply and drainage pipe works, and the allowable seepage water quantity shall be carried out according to the standards of the steel pipe.

Q:There is a gap between the new glass fiber reinforced plastic pipe and its through wall. How can the plug be prevented from leaking through the cracks around the pipe?: Large glass fiber reinforced plastics plants such as the United States and Asia, with FRP through the cabin, can be used to solve your problem, the gap is filled with special blowing agent. In this way, the continuity of FRP material can be guaranteed.

Q:Raw material and mix ratio of inorganic glass fibre reinforced plastic wind pipe: In order to improve the quality of glass.Advanced technology may be used.The ratio seems to be 1 to 0.001. Pretty much within this range.

Q:How to open a DN300 port on the DN600 GRP pipe and install the DN300 gate?!: Do not know the road of glass steel flange have, if any to buy different materials of cast iron flanges or PVCU flange on the same material, the three way behind the pipeline branch, so that the material market has purchased (ABS buy buy in the small town is not easy), the construction is convenient. If it is a glass steel pipe, pipe end cannot change, can only be used to bond the glass steel material, the pipe bonded on the flange is an arc for a plane is bonded with a cast iron pipe flange suggestions. Because the FRP material and most of the plastic are not bonded.

Q:What are the differences between FRP pipes and sand pipes in their uses?: Pressure more than 10 kg, generally do not clamp sand tube. Process tubes are mainly used in highly corrosive workplaces such as acids, alkalis, salt solutions, or high pressure pipes.

Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth: 1) FRP reinforcement, length of rectangular duct is greater than 900mm, and the pipe length is more than 1250mm, should be strengthened. The reinforcement shall be made of bulk material (fiber reinforced plastic) and reinforced plate at the maximum stress, so as to increase the modulus of the section and increase the overall strength of the tube. FRP reinforcement can also be in the wind pipe production is completed, the treated metal or other corrosion resistant material for reinforcement, reinforcement and FRP as a whole, and with the same pipeline body cementitious material sealing gap2) hobas pipe surface thickness of the slurry to flatten the glass fiber mesh cloth texture is appropriate (see:). No dense air holes and grout leaks are allowed on the wall of the pipe to avoid the stress concentration under the bending tensile stress (positive air pressure) and the bending compressive stress (negative wind pressure).3) FRP pipe and flange corner should transition arc, transition radius to wall thickness of 0.8 ~ 1.2 times, improve the bearing capacity and the cantilever flange to avoid stress concentration. Fiberglass mesh shall be extended to the duct at the flange of the duct.
