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:Can FRP pipes be used in heating pipes?
Glass steel pipe road does not belong to common heating pipe material.Heating pipe requirements are solid, high temperature, pressure, easy connection, convenient construction.Usually, heating pipes are made of steel and materials are more common.
Q:Uneven settlement of the foundation, can lead to glass fiber reinforced plastic underground water pipes burst, what is the principle?
Can cause rupture. FRP material originally resistant to pressure better, tensile, shear resistance is poor, the foundation sinking is shear, I want to sink more than 5 cm, if the soil around the pipeline is compacted, it may break
Q:What are the posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?
FRP material has the characteristics of excellent corrosion resistance, no underground water or sewage pipe tube with acidic or alkaline causes no damage to the use of the product, and the product itself, do not need to do any protective measures, steel pipe and concrete pipe does not have the advantage.
Q:What kind of material are the flanges and valves on the GRP pipe?
It's better to use plastic or polyurethane
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:How is FRP ventilation pipe made?
It should be noted that the flange and the duct shall be a whole and shall be at right angles to the axis of the wind pipe. The flanges of the air duct and its pipe end shall be formed together during the coating process. Glass fibre reinforced plastic pipe flanges shall conform to the provisions of table 5-21.
Q:Glass fiber reinforced plastic pipe to withstand 1.0MPa pressure, pipe wall to do how much thickness?
This depends on the size of the pipe diameter, the greater the diameter, the thicker the wall.
Q:What are the advantages of FRP pipes?
Light weight, corrosion resistance, aging resistance, long service life,
Q:What are the specifications of glass fibre reinforced plastic cable pipes? What are they?
Strong corrosion resistance, insulation, non magnetic, acid, alkali, flame retardant, anti-static. The utility model has the advantages of good elasticity of bending modulus, complete solution of the corrosion of the metal pipe, no distortion and elasticity, and the defects that the plastic tube is easy to aging and the impact resistance is poor. Good water resistance, can be used in damp or water for a long time without deterioration. Due to the specific properties of glass fiber reinforced plastic, the service life of the glass steel pipe is more than 50 years. The construction is convenient, in particular the repair project, the efficiency is particularly prominent, is the power cable communication cable engineering, municipal engineering and road underground cable is the most ideal protective device, the cable bridge across the river, the use of the most suitable and convenient.
Q:Which is better, pultruded FRP square pipe with PVC?
When a material with higher temperature is conveyed in a wear-resistant pipe, there is a problem that the price of the heat-resistant steel pipe is very expensive. These problems can be easily solved after the wearable pipeline is put on the market. Widely used in wear-resistant pipe wear serious mine filling, ore concentrate and tailings transport, coal-fired power plant powder, slag, ash and other wear-resistant pipe is also very suitable.
