Gravimeter System
High precise Gravimeter control system of is applied in this PE-RT pipe production line.
(1 )It is used for measuring & calculating and precise control of pipe weight per meter and its extrusion output, to realize the constancy of pipe weight.
(2) The application of this system can shorten the start-up time, improve the produced pipe quality, and save raw material.
Die head
(1)The specially designed spiral pressure-storage die head of this PE-RT pipe making machine effectively overcomes the instantaneous fluctuation of extrusion pressure,
(2)Realizing high speed and constant pressure extrusion of materials.
Automatic Coiler
The automatic double working position pipe coiler of this PERT pipe machinery can realize automatic reel changing according to set length,automatic cutting and coiling.
(1) Using servo controlled high precise traversing device and tension control device.
(2) SIEMENS PLC independent control.
Siemens PLC control system
(1)The production line to make PERT pipe adopts original new generation PLC control system.
(2) Adopting Multi-point closed loop control system, ensuring high speed synchronous control and reliable operating.
Other Functions
Added some auxiliary machine, the PERT pipe production line can produce three layer or five layer EVOH/PERT pipe.
PERT Pipe Application Introduction
Pert pipe, or heat-resistant polyethylene PERT pipe, is the abbreviation of polyethylene of raised temperature resistance. It is a kind of non crosslinked polyethylene that can be used in hot water pipes. Pert is a kind of medium density polyethylene with stable mechanical properties Because of its unique structure of ethylene main chain and octene short branch chain, it has excellent toughness, stress cracking resistance, low temperature impact resistance, long-term water pressure resistance and heat creep resistance of octene. Pert pipe adopts two kinds of hot-melt process: hot-melt socket welding process and hot-melt butt welding process.
Application fields of PERT pipes and fittings
1. Cold and hot water pipe
(1) Excellent low temperature brittleness resistance. Because PERT is polyethylene with similar molecular structure, it has better low temperature brittleness than PPR. The low temperature brittleness of PPR is + 5 ºC, while that of PERT is - 40 ºC.
(2) The high temperature resistance of PPR is 70 ºC and pert is 90 ºC.
(3) The pressure bearing performance is superior. Under the same service conditions, because PERT pipe has higher design pressure and better pressure bearing capacity, under the same pressure bearing conditions, PERT pipe has thinner wall thickness, larger diameter and more sufficient flow.
(4) The flexibility of the product is good, and it can be connected in a variety of ways, which makes the construction of the product more convenient and time-saving.
2. Solar tube
PB pipe and stainless steel pipe can also be used as solar energy pipeline, but they are difficult to be popularized due to price or construction factors.
3. Industrial pipe
Industrial conveying system
The temperature of industrial transportation medium is relatively high, and the general corrosion is strong, so the transportation pipeline system is required to have good high temperature resistance, corrosion resistance and chemical resistance. Pert pipeline products have high chemical corrosion resistance at high temperature and excellent pressure resistance at high temperature, which fully meet the requirements of industrial transportation.
