Polypropylene Pipes - features and specifications

Types of polypropylene pipes

Polypropylene pipes PN-10 can be used in a variety of areas, including industrial.This marking indicates that the specifications of polypropylene pipes allow to apply them at a pressure of the fluid up to 10 atmospheres.Such communication can withstand liquid temperatures up to 45 degrees, so it is advisable to use them in the cold water supply systems or "warm floor" systems.Polypropylene, whose characteristics are such as defined above, has the lowest cost.

pipes PN-16 fluid pressure is maintained up to 16 bar and temperatures up to 60 degrees.They are considered versatile because they can be used in the systems of both cold and hot (60 degrees) water.Marking

PN-20 indicates that the pipes are intended for vehicles with pressure up to 20 atmospheres and temperatures up to 80 degrees.Such communication can be used in hot water and district heating networks.

Marking polypropylene pipes PN-25 indicates the presence of the reinforcing layer of aluminum foil.With the additional layer increases the working pressure up to 25 atmospheres, and withstand temperatures up to 95 degrees.Communication is of the type used in the heating system.

choosing a certain type of pipe, it is worth remembering that the fittings and valves must be appropriate.

Advantages of polypropylene pipes

• The first and most important advantage - it is durability.Manufacturers claim that the period of use of these products is more than 50 years under normal usage.
• Polypropylene communications are not subject to corrosion, acids, solvents, deposition on the inner surface of the salt and lime.Also they lack the bacterial flora.
• pipes made of polypropylene resistant to defrost - if the transported fluid temperature drops below zero, the products of this material is slightly expanded, and later return to the same size.
• Polypropylene, the characteristics of which exclude the occurrence of condensation, has low thermal conductivity.This ensures that the temperature of the coolant at the inlet and outlet of the system remains the same.

• Installation polypropylene communication much easier and faster.diffusion bonding technology allows to obtain high-quality connection.Furthermore, polypropylene products have less weight compared to similar products made of steel.
• No electrical conductivity, so it does not take place stray currents.
• not there noise from water flow due to the smooth inner surface of the flow resistance decreases.
• PP - an environmentally friendly material that does not harm the environment or the operation of, or for disposal.
• important advantage of polypropylene pipes is their low cost.Furthermore, they do not require additional care.

Where applicable polypropylene pipes

Polypropylene products due to its characteristics can be used in the following areas:

1. for domestic hot and cold water, heating, sewerage, underfloor heating.
2. for removal of soil and waste water (due to the high chemical resistance).
3. in irrigation, land reclamation and drainage systems.
4. for transporting chemically aggressive media and compressed air.
5. for ventilation.

Technology of polypropylene and features of installation of communications

best raw material for plastic pipes are polypropylene copolymer pellets - randomness type PPR 80. This rugged, lightweight copolymer obtained by modifying the structure of polypropylene (adding to its molecularchain of ethylene molecules).That explains the structure of a modification of material properties such as elasticity, temperature strength, low thermal conductivity.

Installation polypropylene piping is performed by diffusion or socket fusion using the fittings (angles, tees, etc.).Compounds obtained absolutely uniform, reliable and piping becomes tight.

Today, the best material for pipelines is precisely polypropylene, the characteristics of which are considered the best.
