PP-R PIPES & FITTINGS

PP-R pipe, also called polypropylene random copolymer pipe(3 style), is a new generation of green building material developed and produced in the 1990s. As light as other common plastic pipes, it is corrosion-resistant and antiscaling, and has a long life span with its excellent hygienic properties and good thermal endurance quality. It is genuine green building material in reality as well as name for its low coefficient of heat conductivity, heat preservation, energy conservation, easy installation, dependable hot melted connection and recyclable materials. Unlike copper-plastic composite pipe, PP-R pipe can have heavy caliber pipes produced, with a maximum caliber of over 160mm.

 

PRODUCTS FEATURES

1. Healthful, innocuous: the product belongs to environmental green protective building materials. It can be used in piping system of pure water and drinking water.

2. Anticorrosion,anti-encumbrance: using the pipes can avoild the rustlings of laver and bathtub which was given rise to by piping rust eaten and it also can avoid the clogging which induce by piping rust eaten

3. High temperature and pressure resistance the water temperature that transport by the pipes can reach 95°C when working under the long term consecutive working stress.

4. Heat preservation and energy saving: coefficient of heat passage of the piping just one of two hundred as metallic conduit and the heat preservationand energy saving efficiency are very good when used as hot water line.

4. Lightweight: the piping specific gravity of the piping just as one of seven as metallic conduit.

5. Beautiful shape:the inside and outside of the production is very lubricous, fluid resistance is little color and luster is very meekness and it has attractive appearance.

6. The fitting of the piping is very convenient and credible: adopting hot melts joint only needs a few seconds and very on the safe side.

7.The working life of piping is very long:its working life can reach at least 50 years under normal use.

Application areas

1. Hot and cold water systems for industrial and civil construction

2. Purified water supply system for direct drinking

3. Central air-conditioning system and compressed air pipes

4. Water supply pipe lines specialized for solar energy

5. The buildings use interior heating systems, including floor, wall panel heating, and radiant heating systems

6. Drink production and delivery system

7. Delivery and discharge systems for industrial chemical mediators

8. Other industrial and agricultural pipes

 

INSTALL IMPORTANT POINT

The connection of pipe and fittings is hot melt. Flange is used to connect the steel pipe.During hot melt connection use welding machine. The quality of welding machine must be guaranteed. To make sure the quality of connection.The portable welding machine applied to the final connection of the pipe and system of dn<63mm. The desk-mounted welding machine applied to the preframe connection of the pipe of dn75-160mm.During heating and peg graft, we can’t move the pipe and fittings. We should insert them directly.Welding technical parameters

OD(mm)	Welding depth(mm)	Heating time(s)	Welding time(s)	Cooling time(min)
20	14	5	4	2
25	15	6	4	2
32	16.5	8	6	4
40	18	12	6	4
50	20	18	6	4
63	24	24	8	6

90	32	40	10	8
110	38.5	50	15	10
160	55	80	30	20

TIP: The welding time should delay 50% if the working temperature below 5 °C.

5.After the pressure testing we can close the pipe and use.
