I. Pipe Description:
''Palconn'' PEX cross-linking polyethylene) pipe adopts HDPE as main material, chemical covalent bonds formed in polyethylene molecular chains through cross-linking making molecules forming three dimensional net structure, having good heat & pressure resistance, and other physical and chemical performance.

II. Advantages:
1.Environment-protecting, complying with GB/T17219-1998
2.Wonderful heat-resistance,safe working temperature ranging from -70°C to +110°C
3.High thermal conductivity coefficient up to 0.45m/m.k, especially suitable to floor-heating & cold-hot water supply system
4.Long service life of 50 years
5.Good impact strength and reliability
6.Anti- corrupted, can be used for petrol, chemical, and gas pipe

III. Application:

1.Floor heating for all kinds of building;
2.Air-conditioning, solar water heaters, hot and cold water piping
3.Petroleum chemical, pharmaceutical and food processing industries etc, fluid delivery pipeline
4.Refrigeration systems and water treatment systems pipeline
5.Building tap water, purified water, and other hot and cold water pipes
