Non-toxic: no heavy metal additives, would not be covered with dirt or contaminated by bacterium. 

 Corrosion Resistance: resist chemical matters and electron chemical corrosion. 

High Flow Capacity: smooth interior walls and low friction result in low flow resistance and high volume. 

 Excellent Flexibility: can be supplied in coil.

Low Installation Costs: light weight and ease of installation can reduce installation costs 

Longevity: more than 50 years under proper use © Recycled and Environment-friendly

Applications of PPR Pipes and Fittings

Cold and hot water supply 

PP-R pipes are commonly used in both hot and cold water supply systems in homes, apartments, and commercial buildings. They are highly resistant to scaling and corrosion, making them an ideal choice for water distribution.

Heating system including flooring heating, wall heating and radiant system 

PP-R pipes has the advantage low energy consumption,It is an excellent choice for energy-saving residential and commercial heating solutions.

Central air conditioning system 

PP-R pipes are used in certain compressed air applications, especially in low- to medium-pressure systems. The smooth interior of the pipes reduces the risk of blockages, making them effective for air distribution.

Swimming Pools

PPR Pipes and Fittings are commonly used in pool water circulation and filtration systems, as they are resistant to chemicals like chlorine, which are frequently used in pool maintenance.

Packing and Shipment

Depends on the products and qty,we could make the packing of coiling,rolls,bundle packing,crates or boxes,etc.

Shipment:By sea,railway,by air or as customer’s request.

FAQ of PPR Pipes and Fittings

Q1,How many structure of PPR pipe have?

1. Single layer structure

The single-layer structure is the basic structure of PPR pipes, which is made of one layer of polypropylene material. The structure has the advantages of simplicity, beautiful appearance and moderate price.

Fiber reinforced structure

The fiber-reinforced structure is a PPR pipe with a relatively complex structure. It consists of a multi-layer structure, in which the fiber-reinforced layer is directly connected to the inner and outer layers by heat welding. The advantages of this structure are high strength, impermeability and long service life.

Q2,How to choose PPR pipe?

1. Select materials according to usage scenarios:

Different use scenarios have different requirements for PPR pipes. For example, the water supply field requires relatively high material and strength requirements for PPR pipes, while the drainage field requires pipes with good toughness.

2. Select according to the pipe diameter:

The diameter of the PPR pipe usually has multiple specifications such as 20mm, 25mm, 32mm, 40mm, 50mm, etc., and the appropriate diameter can be selected according to the needs.

3. Select according to the pressure and temperature used:

The choice of PPR pipe should also be selected according to the pressure and temperature to be borne. For example, in some high-temperature scenes, high-temperature PPR pipe materials should be selected.

Q3,How many types of PPR pipes?

1. Ordinary PPR pipe

Ordinary PPR pipes refer to ordinary pipe materials that are normally used, and are usually used in water supply, drainage, and gas fields. The pipe is characterized by high density, high strength, aging resistance, corrosion resistance, impact resistance, safety and environmental protection.

2. PPR reinforced tube

PPR reinforced pipe is a pipe made of specially added reinforcing materials, which is more excellent than ordinary pipes in terms of strength and pressure resistance, and is widely used in industries, construction and agriculture.

3. PPR fiber reinforced pipe

PPR fiber reinforced pipe is a new type of PPR pipe, which adds fiber materials on the basis of raw materials. The biggest feature of this pipe is its high strength, while maintaining the advantages of PPR pipes, it is widely used in high-rise buildings, water supply, heating and floor heating and other fields.

Q4,What are the PPR fittings accessories?

The most common PPR fittings include:

Elbows: Used to change the direction of the pipe.

Tees: For branching off the pipe into two or more directions.

Couplings: To connect two pipes of the same diameter.

Adapters: Used to connect PPR pipes to pipes of different materials, such as metal or PVC.

Reducers: To reduce the pipe size when connecting to smaller pipes.

End Caps: To close the end of a piping system.
