Stainless steel pipe DN12-DN25

Product detailed description

Stainless steel corrugated pipes are commonly used in residential and commercial buildings for water supply and heating systems. These pipes are ideal for connecting domestic hot water systems, central heating circuits, and boiler installations. Installers often use them for retrofitting existing systems or for new builds where flexibility and corrosion resistance are essential. The corrugated design allows for slight movement and thermal expansion without compromising the integrity of the system.

These pipes are frequently installed in kitchens, bathrooms, and mechanical rooms where space constraints and the need for flexibility are common. They are also used in industrial applications where resistance to corrosion and high temperatures is required. The installation involves securing the pipe with appropriate fittings and ensuring that all connections are tight and leak-free. The absence of insulation makes them suitable for internal installations where thermal isolation is not required.

Technical parameters

Installation and connection

Installation involves cutting the pipe to the required length and connecting it using appropriate fittings such as compression or push-fit connections. The nominal diameters correspond to internal and external dimensions: DN12 has an internal diameter of 12 mm and an external diameter of approximately 16 mm. DN16 has an internal diameter of 16 mm and an external diameter of approximately 21.3 mm. DN20 has an internal diameter of 20 mm and an external diameter of approximately 27 mm. DN25 has an internal diameter of 25 mm and an external diameter of approximately 31.5 mm. It is important to ensure that the pipe is not bent beyond its flexibility limits and that all connections are properly sealed. Common installation mistakes include using incorrect fittings or failing to check for leaks after installation.

Compatibility and accessories

This pipe is compatible with standard water and heating systems. To complete the installation, additional accessories such as compression fittings, expansion joints, and sealing rings are required. These accessories ensure a secure and leak-free connection and help accommodate thermal expansion and contraction.

Technical background for designers

Stainless steel corrugated pipes operate on the principle of flexible yet durable piping that can withstand thermal expansion and contraction. The material is resistant to corrosion and can handle high temperatures, making it suitable for both potable water and heating systems. The corrugated design allows for slight movement without compromising the structural integrity of the pipe. The integration into the system depends on the flow rate and pressure requirements. The service life and efficiency of the system are influenced by the quality of the connections and the environmental conditions in which the pipe is installed.

Service and operation

Regular inspection of the pipe and its connections is recommended to ensure there are no leaks or signs of wear. The absence of insulation means that the pipe should be installed in areas where exposure to extreme temperatures is not a concern. No specific service intervals are provided in the technical data, but any signs of damage or leakage should be addressed immediately to prevent system failure.
