Description

Floor heating pipe refers to a kind of pipe used as the carrier of low-temperature hot water circulation in the low-temperature hot water floor radiant heating system (referred to as floor heating). PERT floor heating special pipe: PERT pipe is laid under the floor, using hot water with a temperature not higher than 60℃ as the heat medium, circulating in the heating pipe to heat the floor, so as to realize large-area radiant heat transfer and create a kind of comfort that meets the requirements of human body. The indoor environment is a modern new type of heating pipeline system.

The raw material of PERT floor heating pipe is a kind of medium-density polyethylene with very stable mechanical properties, which is made by the catalytic copolymerization of ethylene and octene monomers. It does not require cross-linking in the production and processing process, the production process is simple, easy to control, and the quality of the pipe is stable and reliable. PERT floor heating pipe is the only plastic that does not need cross-linking and can have long-term hydrostatic performance at water temperature below 60 degrees. Pipe. When the working temperature is >60℃ and the pressure is 0.8MPa, the service life can be safely used for about long-term durability according to standards.

PERT Feature

The floor heating material is a medium-density polyethylene with very stable mechanical properties, which is formed by the copolymerization of ethylene and octene monomers through metallocene catalysis. Its unique ethylene main chain and octene short-branched structure make it have the excellent toughness of ethylene, stress crack resistance, low temperature impact resistance, outstanding long-term water pressure resistance and octene heat creep resistance.

1. Flexibility: PE-RT is relatively soft. No special tools are required during construction, so the processing cost is relatively low.　

2. Thermal conductivity: pipes used for floor heating need to have good thermal conductivity. PE-RT has better thermal conductivity, and its thermal conductivity is twice that of PP-R and PP-B pipes. It is very suitable for floor heating.

3. Low temperature thermal shock resistance: PE-RT has better low temperature shock resistance. During winter construction, the pipes are not susceptible to being impacted and broken, which increases the flexibility of construction arrangements.

4. Environmental protection: PE-RT and PP-R can be recycled and will not pollute the environment. The PEX cannot be recycled will cause secondary pollution;

5. Stability of processing performance: PEX has the problems of controlling the degree of cross-linking and cross-linking uniformity. The processing is complicated and the processing directly affects the performance of the pipe. However, PE-RT and PP-R are easy to process, and the performance of the pipe is basically determined by the raw material, and the performance is relatively stable.

PE-RT can be connected by hot-melt connection, accidentally damaged can also be repaired by hot-melt connection of pipe fittings. The floor heating material has a creep failure curve that meets the product standard. It is the only type of polyethylene that can be used for hot water pipes without cross-linking at this stage.
