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 posts of glass fiber reinforced plastic sand pipe and the corresponding occupational hazards and protection?

Glass reinforced plastic underground sand pipe has long service life without operation and maintenance, which is the biggest advantage of this product. Since pipe jacking is an underground concealed project, its service life is undoubtedly the very important consideration of decision-makers. The service life of glass fiber reinforced plastic sand pipe jacking is more than 50 years, which is incomparable to the products such as steel pipe, concrete pipe and so on.

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.

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 more and more people choose FRP pipe?

The cost performance of FRP pipes is higher than that of PP, PVC, PE or concrete, and the strength, hardness and toughness of PP, PE and PVC are not as good as those of FRP pipes

Q:What kind of project needs fiberglass pipe?

Glass fiber reinforced plastic products are characterized by corrosion protection, high temperature resistance, humidity resistance, alkali resistance, etc., where it is necessary to use the glass fiber reinforced plastic pipe!!

Q:What are the advantages of glass fiber reinforced plastic sand pipe than HDPE pipe?

Both have their merits, but it depends on their choice!

Q:What is the structure and function of glass fiber reinforced plastic lining?

The structure is made up of colloid + glass cloth. The construction process is like this:1, carbon steel inner wall grinding acute angle, rust removal2, brushing glue3, cloth affixed4, brushing glue5, cloth affixed

Q:What's the difference between glass fiber reinforced plastic pipe and glass fiber reinforced sand pipe?

Glass reinforced plastic sand pipe is actually in the production of glass fiber reinforced plastic pipe, in the middle to increase a layer of sand layer, the purpose is to increase the rigidity of the pipeline. 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:How to install FRP pipe correctly

Glass tube and carbon steel pipe connection, at present, the most reliable way of connection is indeed onlyOther, such as on-site bonding, because of the two kinds of material is not the same, the quality of bonding is not very stable!
