Cross-linked polyethylene pipe(PEX)

Description:

Cross-linked polyethylene pipe has a very good health due to comprehensive mechanical and physical properties, is considered a new generation of green pipe. Production of cross-linked polyethylene pipe (PEX) is the main raw material HDPE, as well as the initiator, crosslinking agent, catalyst and other additives, using the world's advanced one-step (MONSOIL France) technology, using ordinary polyethylene materials by adding silane access sticks material, in the polymer molecule chains to form a chemical covalent bond to replace the original van der Waals forces to form the three-dimensional network structure of the text-chain cross-linked polyethylene, the crosslinking degree of up to 60% -89%, so that of its excellent physical and chemical properties.
cross-linked polyethylene pipe of the main features:
Use a wide temperature range,-70 ℃-95 ℃in the next long-term use;
texture, firm and patient pressure resistant high strength,20 ℃when the burst pressure is greater than 5Mpa,95 ℃when the burst pressure is greater than 2Mpa,95 ℃under 50 years service life;
does not rust resistance, good chemical resistance, excellent resistance to environmental stress cracking, even in the more out of temperature can also be used to transport a variety of chemicals and stress cracking of accelerating a variety of fluid pipe;
Pipe wall tension is low, so that the higher the surface tension of water infiltration is difficult wall, you can effectively prevent scale formation.
non-toxic, non-mildew, do not breed bacteria, public health in line with the national standard GB7219-1998 'drinking water distribution equipment and protective materials, safety evaluation standard' provisions of indicators;
pipe inner wall is smooth, fluid flow resistance is small, excellent mechanical properties of the water in the same diameter, the transmission fluid flow than metal pipe large, low noise;
pipe thermal conductivity much lower than the metal pipe, so its excellent insulation properties of insulation for the heating system, without insulation, heat loss is small;
good memory performance, when the PEX pipe is heated to the proper temperature (less than180 ℃) will become transparent and shaped, and then cooling will be restored to its original shape, that is, any error in the course of the bending are can be corrected through the hot air gun, to use more freely;
light weight, easy handling, easy installation easy, non-professionals can also be successfully installed, install the workload of less than half the amount of metal pipe installation;
Cross-linked polyethylene pipe of the linear expansion coefficient of metal pipe to a large and more space for installation should be left flexible.
cross-linked polyethylene pipe main application areas:
Building hot and cold water and drinking water plumbing systems;
Food Industry in the liquid food pipeline;
plumbing heating system, central air-conditioning piping systems, ground radiation; heating systems, solar water heater system, etc.;
telecommunications, electrical use with tube;
plating, petrochemical and other industrial piping system.

Advantages of Flexible PVC conduit Pipe:

1. The flexible pipes have extremely good waterproof, insulating and pull resistance.
2. The thickened surface is made of PVC. Fire retardant was added to the PVC plastic.
3. The structure is buckle structure, which enhances the pull resistance and is not liable to crack or deform.
4. Extremely soft with food bending performance. The inner smoothness makes the entry of wires very easy.

Application of Flexible PVC conduit Pipe:

PVC conduit serves two primary industries: communications (telephone, CATV, data transmission) and electrical (power transmission).In the communications industry, the advent of fiber optic cable has had a tremendous impact due to its significantly higher data-carrying capacity, particularly due to the explosion of the Internet. In telecommunications service (phone, data transmission), fiber optic cable is used, along with traditional copper cable. In cable television service (CATV), fiber optic is also growing rapidly in addition to (or replacing) coaxial cable. This progression toward fiber optic cable has made the need for protection more critical, since these materials are highly sensitive to moisture and mechanical stress. Damage can be very expensive in terms of interrupted service and replacement costs. Also, these cables are installed in very long, continuous runs which require a clear, protected pathway, as well as a leak-free system for air-assisted ("blow-in”) installations. In addition to fiber optic, coaxial cables have seen improvements to increase bandwidth, making these materials more mechanically sensitive.
In the electrical industry, a critical requirement is on maintaining uninterrupted service, as consumers and businesses are even less tolerant of power outages than they are of phone or CATV service interruptions. Although many direct-buried power cable systems are designed for 30- or 40-year lifetimes, they are susceptible to external influences like rock impingement and often require frequent repairs. Conduit is finding favor over direct burial in these applications due to improved protection, but it must be continuous and facilitate quick repair operations.PVC conduit is used to carry both primary (substation to transformer) and secondary (transformer to end-user) cables. Some of these installations also contain fiber optic cables placed alongside the power cables to connect with load-monitoring sensors located throughout the network.
