PPR hot water plumbing pipe specification
​PPR hot water pipes are generally used as heating connecting pipes, and can also be used for hot water pipes of water heaters. Because of their high temperature and high pressure resistance, they are often used as home improvement pipes. Pipeline water temperature can reach 95°C (not suitable for long-term use).

How much pressure can the PPR hot water pipe withstand?

The pressure of the PPR water pipe depends on the S grade, such as the S4 series, then the nominal pressure is 1.6mpa, which is 16kg of pressure.

The nominal pressure of S5 type PPR pipe (C=1.25) is Mpa1.25

The nominal pressure of S4 type PPR pipe (C=1.25) is Mpa1.6

The nominal pressure of S3.2 type PPR pipe (C=1.25) is Mpa2.0

The nominal pressure of S2.5 type PPR pipe (C=1.25) is Mpa2.5

PPR hot water pipes are generally used as heating connecting pipes, and can also be used for hot water pipes of water heaters. Because of their high temperature and high pressure resistance, they are often used as home improvement pipes; PPR is a random copolymer of propylene and ethylene, and PP-R pipes are It is made of PP-R resin by extrusion. We have Complete PPR hot water plumbing pipe specification in China.

What are the characteristics of PPR insulation pipe

1. Good stability: good temperature resistance and heat preservation, thermal conductivity is only 1/200 of that of steel pipe, generally no heat insulation treatment is required; in addition, the elastic modulus is small, and the expansion force caused by temperature changes is relatively small Small, suitable for embedded wall and direct burial under the floor.

2. Smooth water supply: the inner wall is smooth, the system pressure is small, and the fluid resistance is small, so the flow rate is large and the speed is fast.

3. Long service life: Advanced technology and high-quality raw materials make PP-R pipes have strong anti-aging characteristics. The product can be used for a long time under the conditions of 8400h, 95°C and pressure of 0.82MPa, and the service life can reach more than 50 years.

4. The connection is firm and never leaks: the same material is fused together by welding. The tensile, bending and impact strength of the joint is higher than the strength of the pipe body itself, so as to eliminate the hidden danger of water seepage at the joint. Generally, no maintenance is required after installation. However, places near heat sources, metal sharp objects or instruments need to be checked frequently to see if the outside of the pipe is damaged.


PPR Hot Water Plumbing Pipe Specification


PPR (Polypropylene Random) pipes are widely used for hot water plumbing systems due to their excellent heat resistance and durability. Here are some common specifications for PPR hot water plumbing pipes:


Material: PPR pipes are made from high-quality polypropylene random copolymer (PPR-C) material. The material is specifically designed to withstand high temperatures and provide long-term performance.


Size: PPR hot water plumbing pipes are available in various sizes, typically ranging from 20mm to 110mm in diameter. The specific size needed for a project depends on the flow rate and requirements of the hot water system.


Pressure Rating: PPR pipes have different pressure ratings to accommodate various applications. Common pressure ratings for hot water plumbing pipes include PN10 (1.0 MPa), PN16 (1.6 MPa), and PN20 (2.0 MPa). The pressure rating indicates the maximum pressure the pipe can handle.


Color: PPR hot water plumbing pipes are usually available in green or white color. The color coding helps to differentiate between hot water and cold water pipes within the plumbing system.


Connection Types: PPR pipes can be connected using different methods, including socket fusion, butt fusion, and electrofusion. Socket fusion is a common method where the pipe ends are heated and joined together using a socket fusion welding machine.


Standards: PPR hot water plumbing pipes should comply with relevant standards and regulations in the specific region or country. Common standards for PPR pipes include DIN 8077/8078 (Germany), ISO 15874 (International), and ASTM F2389 (United States).


Temperature Range: PPR hot water plumbing pipes are designed to withstand high temperatures. They can typically handle hot water temperatures up to 95°C (203°F) for continuous operation. However, the specific temperature limits may vary based on the manufacturer and the standard followed.
