Description

Junnuo can provide a range of backing rings for mechanical connections in galvanised steel, stainless steel, ductile iron and polypropylene coated steel. There always using for the plastic piping system in Chemical, mining, water, petrol, etc. Systerm.

We also can provide PP reinforced, full plastic flange backing rings, and PP coated steel backing together with full range for plastic stub ends in EN, ISO, USA standard etc.

PP-STEEL Flange is a pipe connector that combines the properties of steel and polypropylene (PP) to achieve connections between pipes. This flange is commonly used in industrial piping systems, especially in applications that need to withstand certain pressures and temperatures.

 

Function

1. Connection function: The main function of the flange is to connect two pipes, equipment or components so that they can move against each other and transmit force. PP-STEEL Flange also has this function, which can ensure a stable connection between pipes, equipment or components.

2. Sealing performance: PP material has good corrosion resistance and sealing performance, so PP-STEEL Flange can provide reliable sealing effect during the connection process, prevent medium leakage, and ensure the safe operation of the pipeline system.

3. Corrosion resistance: PP coating can effectively resist the erosion of various corrosive media, making PP-STEEL Flange have a longer service life in corrosive environments such as chemical industry and water treatment.

4. High temperature resistance: PP material has high temperature resistance and can maintain stable performance in high temperature environment, so PP-STEEL Flange is also suitable for high temperature working conditions.

5. Lightweight and strong: Compared with pure steel flanges, PP-STEEL Flange has a lighter overall weight due to the lightweight characteristics of PP material, making it easier to carry and install. At the same time, the steel matrix ensures its strength and load-bearing capacity.

6. Cleanliness and hygiene: PP material has a smooth surface, is not easy to absorb pollutants, and is easy to clean and maintain hygiene. Therefore, PP-STEEL Flange has advantages in industries with high hygiene requirements such as food and pharmaceuticals.
