Product: PPR ball valve
1. Material: 100% virgin PPR material
2. Style: Socket, Thread
3. Connection: socket, flange, threaded/screw
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 avoid 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 preservation and energy saving efficiency are very
good when used as hot water line.
4. Light weight: 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.
Advantages
1. High temperature resistance: the maximum sustained working temperature is up to 70 degrees, the maximum transient temperature is up to 95 degrees.
2. Heat preservation: low thermal conductivity result in preserving heat.
3. Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium.
4. Lower installation costs: light weight and ease of installation can reduce installation cost
5. Higher flow capacity: smooth interior walls result in low pressure loss and high volum
6. Secure connection: well fusion performance; and adopted advanced fusion connecting technology to integrate whole pipe system, which reduce the possibility of leakage.
4). Install Important Point
The connection of pipe and fittings is hot melt. Flange is used to connect the steel pipe.
1>.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.
2>.During heating and peg graft, we can’t move the pipe and fittings. We should insert them
directly.
