Product Description:

  Passed the ISO9001 quality system in 1998, three times acquired Jiangsu province quality management prize, the high pressure piping product has passed an American API certificate. In 2006,FRP pipes with"Lianzhong"Brand" certificate.Zhongfu Lianzhong group is the only company with large capacity of FRP products exporting.

 The products were exported to Pakistan, Vietnam,Malaysia,Indonesia,Italy,Germany etc,;it is the only manufacturer with supplying large diameters FRP pipes in construction of nuclear station,Lianzhong supplied large diameters FRP pipes to the second term of Qinshan Nuclear Power Station,Tianwan Nuclear Power Station etc...

 Zhongfu Lianzhong insists on developing with technical innovation. Lianzhong imported advanced winding technology of pipes,tank and high pressure pipe from italy and U.S.A firstly in China. Now Lianzhong has more than twenty production lines of pipes, tanks and high pressure pipes.The total annual capacity of FRP pipes,pipes with sand filler,tanks etc.is 20000 tons. Because of credible quality and good service,Lianzhong's products have been proved by so many years practical use in various fields.Those products have won widely favorable comments from customers.

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:What kind of project needs fiberglass pipe?
Glass fiber reinforced plastic material has the advantages of corrosion resistance, high strength, low weight, and other materials can not be compared, the use of a wide range of purposes, such as water supply, chemical raw materials, hot and hot water transportation, ventilation and so on
Q:What epoxy resin is used for anticorrosion of pipeline glass fiber reinforced plastics?
3PE has been anti-corrosion principle, there is no need for anti-corrosion, but now the domestic situation. Directional drilling pipe cannot be detected and repaired, the anticorrosion layer cannot have serious damage to the pipeline, long-term safety operation, it should be required for coating directional drilling: scratch resistance, abrasion resistance, impact resistance, high hardness, strong adhesion and pipeline, corrosion resistance, water resistance have a good soak, matching and cathodic protection system.
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:How to connect glass fiber reinforced plastic sand pipe?
Socket connection is one of the main connecting type of underground pipelines, the use of double "O" type sealing ring connection, the two sealing rings, the socket has pressure test mouth, the installation must be made up and mouth pressure test in the two ring between each interface can be arranged near side pressure test the test pressure, by design, water consumption is very small, the duration is 3 ~ 5min, with no leakage for qualified, ensure that each of the seal effect to ensure that the entire pipeline system overall pressure test success.
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 are the construction methods of glass fiber reinforced plastic paint anticorrosive pipes?
Epoxy coal tar pitch is a kind of anti-corrosion form with high cost performance. The engineering test shows that the epoxy coal asphalt is used as cathodic protection.
Q:Who knows, how is the glass reinforced septic tank connected with the municipal pipe?
If a glass fiber reinforced plastic outlet pipe is reserved, a new sewage inspection well is installed at the pipe end, and then a sewage pipe is installed to connect the reserved manhole of the municipal sewage pipe.
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:Do I need CCC certification for ventilated GRP?
The air duct is made of 10MM thick fiberglass pipe, and the design of the air duct is wrong. The FRP pipe is developed for fire control and smoke exhaust.
