FAQ of GRE Pipe

Q: What are the basic characteristics of the glass tube

Excellent physical and mechanical properties

Density fiberglass pipe is usually 1.8-2.1g / cm3, about 1/4 of steel, are higher than that of steel, cast iron and plastic than strength. The weight of the glass tube is generally greater than the same size steel 1/3 superior physical and mechanical properties; in addition, the thermal expansion coefficient of the glass tube and steel roughly, only 0.5% of the thermal conductivity of steel, is a good thermal and electrical insulation material.

Q: Is GRE Pipe chemical resistant with a long life?

GRE pipe has a special resistance to chemical corrosion in pipes criss-cross, dotted down environment, you can choose a different corrosion-resistant pipes according to the requirements of the medium.

Q: How are the hydraulic properties?

Water is one of the important mechanical properties of glass pipe. Hydraulic fluid excellent characteristics mean little head loss, you can use a smaller diameter or smaller power pump, thereby reducing the initial investment pipeline projects, save energy, reduce operating costs.

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 are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Oil and gas pipelines used for twenty years, basically no corrosion phenomenon. As part of a group of coal tar epoxy primer and topcoat are based on epoxy resin and coal tar as the main film-forming material, add a variety of anti rust paint, insulating filler, toughening agent, leveling agent, diluent, anti settling agents and other materials, the B component is modified amine curing agent or curing agent the main material, adding fillers. When the product is sold, the A and B parts are supplied together, and the mixture is mixed in proportion during construction.
Q:Is it possible to touch the water when the glass fiber reinforced plastic pipe is polished?
Because the resin curing mechanism of FRP products is resin, resin agent, resin curing agent together to react, and release a lot of heat, this process does not affect the curing process because of a small amount of water and at the same time, if you have a little bit of water molecules would because of the large amount of heat emitted by evaporate, so does not affect the bonding of glass and steel that will not affect the glass steel pipe interface
Q:Pipe installation of glass fibre reinforced plastic pipe
In the area, pipeline installation order system, small diameter and large diameter after the first, the first layer after layer, the first easy, first on the pipe rack even after the equipment, pipeline is connected with the machine principle is from the inside to the outside, in order to reduce the influence of welding stress on the installation precision of the machine, touch the mouth interior with the outdoor pipeline should stay outside.
Q:Slurry circulation glass fiber reinforced plastic pipe
The slurry circulation FRP pipe project has long service life and is safe and reliable. The pipeline is durable and the safety factor is above 6. The pipeline life can reach up to 50 - 100 years. For example, the water supply pipeline from Shenzhen to Hongkong was built on the side of Hongkong, long 50KM, respectively, two kinds of glass pipes with inner diameter, 2.2m and 1.7m, which were installed and used so far in 1965, and they were left intact.
Q:Is it useful to make gas pipelines with glass steel pipes? Or the idea that the technology is mature?
There are ideas, corrosion problems resolved, you can consider the use of casing, you have to consider the length of the pipeline, glass tube links. And that's the pressure on the glass.
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:Designed to support FRP pipes, is it m or mm?
Glass fiber reinforced plastic cable protection tube chemical composition: GRP winding pipe is a kind of glass fiber reinforced plastic product. With the continuous development of glass fiber reinforced plastic molding technology, FRP products have been widely used in various fields. FRP products have the advantages of light quality, high strength, corrosion resistance, long service life, flame retardant, high temperature resistance and various forms of products. Therefore, the industry gradually increase the use of glass fiber reinforced plastic products, which will be reinforced FRP mechanical properties and molding process put forward higher requirements. The forming process of FRP determines its shape, property and application prospect. The mechanical properties of glass fiber reinforced plastics determine whether their products can be widely used in industries with higher mechanical properties. Fiberglass reinforced plastic square tubes can replace some metal pipes used in industrial and civil fields, such as central air conditioning, chemical plants, etc. but glass fiber reinforced plastic square tube products are not common in the market. This is mainly due to the existence of poor strength, easy deformation and other defects.
Q:How can FRP tanks be connected to steel tubes?
Glass tube and carbon steel pipe connection, at present, the most reliable way of connection is only flange connection, other such as on-site bonding, because the two kinds of material is not the same, the quality is not very stable after bonding!
Q:How to install FRP pipe correctly
And glass fiber reinforced plastic parts (three, elbow, etc.) in general, the best way is on-site bonding, quality stability and convenience.
