Control Testing of GRP FRP Flange Adaptor 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:Slurry circulation glass fiber reinforced plastic pipe
The slurry circulation glass fiber reinforced plastic pipe has good heat resistance and frost resistance. It can be used in the range of 40 to 80 degrees for a long time. If the resin is specially formulated, it can work at temperatures above 110 degrees celsius.
Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?
Advantages of FRP pipes:1, insulation, acid, alkali and salt corrosion, antistatic, rust, aging is not easy, the service life of up to 50 years.2, non-magnetic, non electrical corrosion, waterproof performance, and can be used in humid environment or water for a long time without deterioration.3, high strength, is the same degree of the original PE pipe is more than 6 times, light weight, smooth wall, perforated cable when the friction coefficient is small, no cable operation.4, heat resistance, antifreeze, fire protection, fire retardant type. It can be used for a long time at -35 ~ 139 degrees celsius.5. The bending modulus is good, the impact resistance is strong, and it solves the defects of metal tube easy to decay and no distortion and elasticity.6, the cable across the bridge and across the river, the use of glass fiber reinforced plastic catheter is more economical and appropriate.7, construction and installation is very simple, no need to tie steel, pouring concrete.
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 are FRP pipes made of?
Light weightThe weight of the pipe is only 1/4 of the same size and the same length as the ductile iron pipe, and 1/10 of the cement pipe. The transportation is easy to handle and easy to install.
Q:Winding method of glass fibre reinforced plastic pipeline anticorrosive glass fiber cloth
When the length and width of glass fiber mesh are not enough, the method of lap joint must be adopted to improve the tangential bearing capacity of the joint, so as to effectively overcome the radial tensile stress, bending force and bending shear stress. The lap length of the glass fiber cloth at the joint is generally 50 to 100mm, and the joint of each glass fiber cloth should be at a certain distance from the adjacent joint. The longitudinal and transverse joints between adjacent layers shall be greater than 300mm, and the distance from the same seam shall not be less than 500mm.5) paste made of circular duct, glass cloth along the radial 45 degree angle to the direction of cut cloth; conical paste products, according to the fan-shaped cloth.
Q:What is the difference between glass tube, sand pipe and glass tube?
The pipeline in the design according to the use of pressure, stiffness and other conditions to determine the need for sand, if the thickness of the pipe can satisfy the pressure requirements and can meet the requirement of stiffness, is generally not the sand.
Q:Why FRP pipes for outdoor waste gas treatment equipment are selected?
Glass fiber reinforced plastic properties: light and hard, non conductive, stable performance, high mechanical strength, less recycling, corrosion resistance.
Q:How long is the service life of glass fiber reinforced plastic pipes?
Hebei, Qingdao and Beijing have additional production bases and service liaison points. Willing to work with new and old customers to create a beautiful today, Chinese and foreign. The company with integrity development guide thought, company value go production, learning and research Jimo road. The wide customers and cooperation of different geographical identity peer praise richly endowed by nature is a unique, Wuhua Tianbao, day people for the auspicious clouds. The sludge produced by the glass fiber reinforced concrete grille has good sedimentation, which is beneficial to the removal of the suspended substance in the back section. The glass fiber reinforced concrete grille has strong adaptability, can adapt to different water quality range, and has strong endurance to the shock load of water quality and water quantity sudden change. FRP grating treatment efficiency is higher than activated sludge process. The galvanized grating plate has the advantages of advanced structural design, optimum matching of gas and water, and sufficient heat exchange, with the same level in foreign countries and superior output. Galvanized grille plate steel bracket adopts zinc plating treatment, double paint anti-corrosion or electrostatic powder spraying, corrosion resistance is strong, service life over similar products double. The two-way grille ensures the natural delamination of the medium and the impurity, and at the same time, the discharge method is arranged at the bottom of the tank, so that the cleaning is particularly convenient
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:What are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Epoxy coal tar coating consists of two main components with epoxy coal asphalt composition, is a (epoxy) B (curing agent) two-component coating, with good adhesion, toughness, moisture resistance, water resistance, chemical resistance, has the properties of prevent various ions through the film, and is coated with objects with the expansion of shrinkage characteristics. The paint film never falls off or cracks.
