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:What are the materials used in smoke exhaust pipes?
In the production of the coal mine exhaust pipe is indispensable, in underground work, because from the ground, the air is not easy to reach, easy to accumulate large amounts of methane gas, these gases will need ventilation pipe timely transferred to the ground to prevent the explosion in the coal mine ventilation pipe, the material is generally iron and plastic.
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.
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:Are there any differences between FRP pipes and FRP pipes?
Air duct is a pipe system used for air transportation and distribution. There are two kinds of composite air duct and inorganic air duct. The duct can be classified according to the shape and material of the section. Duct made of stainless steel duct, in the bite mouth, rivet joint, flange, four corners and other cracks painted with sealant (such as neutral glass glue). Surface dust and grease shall be removed before applying sealant. According to the section shape, the wind pipe can be divided into circular duct, rectangular duct, a variety of flat air pipe, wherein the circular duct resistance minimum maximum height, making complex. Therefore, the application of rectangular wind tube based. According to the material, the air duct can be divided into metal wind pipe, composite air pipe and macromolecule air pipe.
Q:CGCT what's the meaning of the GRP sand pipe?
If the thickness of the pipe can meet the requirements of pressure, but can not meet the stiffness requirement, will choose to increase the thickness of sand to meet the stiffness (of course can not directly increase the sand thickness to meet the requirement of stiffness, but the cost is too high). Sand sandwiched glass fiber reinforced plastic pipes only have more than one sand sandwiched with glass fiber reinforced plastic pipes, and sand layer can be understood to replace glass fiber with quartz sand. The sand pipe with the same thickness is compared with the glass fiber reinforced plastic pipe, but the sand holding pipe is cheap, but the strength is poor; and the glass steel pipe is opposite.
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.
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:What are the functions of glass fiber reinforced plastics?
Glass fiber reinforced plastic (FRP) is a kind of composite material which has been developing rapidly for more than fifty years. 70% of glass fiber output is used to make fiberglass. Glass steel is much harder and much lighter than steel.
Q:What is the stiffness of FRP pipe?
Stiffness, also called ring stiffness, is a numerical indicator of actual resistance to external pressure. Ring stiffness S definition: S =EI /D 3 (where E is the elastic modulus of the material, I is the moment of inertia, D is the average diameter of the pipe ring), and the ring stiffness is KN/m2.
Q:FRP pipe price
The price range of raw material resin is about 10000/ tons to 60000/ tons.
