•Production Introduction:
A. Be healthful, no chemical and oxidation problems. Meet the demand of GB/T18742.（1.2.3） -2002. Be most suitable for the food industry and water supply, and it can be regarded as green building material and healthful environmental protection product.
B. Easy and reliable installation. The homogenous fuse connection makes a nodal head fixed within several seconds, which is convenient and time-saving.
C. Heat preservation and heat insulation: the coefficient of heat conductivity is only 1/200 of that of the metal pipe, so the heat preservation and heat insulation effect of the heat water pipe is excellent.
D. Light weight, high specific strength: the proportion is only 1/8 of that of the metal pipe. The compression resistance test grade can be over 5Mpa（50kg/c㎡. And thus the product has good flexibility and shockproof performance.
E. The product has smooth wall and outerwall, low flow obstruction and noise.
F. High heat resistance performance: the low heat conductor can sustain the hot water and high pressure. Under the specified long-term constant working pressure, the water temperature of the pipe can reach 95℃.
G. The product has high suppleness, so it can endure bitter cold and high temperature and has good expansion performance.
H. Anticorrosion and no scale formation: it can avoid the scale formation in the pipe and the yellow spot and rust in the bathtub.
I. Long using life: up to now the PP-R pipe has been the pipeline with the longest life.
J. Returnability: it is the green environmental protection product that has no pollution during the production, construction and using process.

•The Jointing Points of the Products:
1. The connection between the tubular products and the pipefittings should adopt fuse connection mode, and they are not allowed directly assembled. The pipefittings with metal insert are necessary when being connected with the metal pipe and water utensil.
2. The table heat sealer is suitable for the connection of the big pipe, and the handheld heat sealing tool is suitable for the connection of the small pipe and system.
3. The heat seal operation should be carried out strictly according to the specified technical parameters. During the heat and inserting process, please don't turn the tubular products and pipefittings; instead, please insert directly. An equal seal circle should be on the connecting surface under the normal heat seal conditions.
4. After the operation, the tube sealing and using cannot be carried out until the pressure test and acceptance is completed.
