Reduction coupling SANHA SANHA-THERM C-Stahl 22x15 mm

Reduction coupling SANHA SANHA-THERM C-Stahl 22x15 mm is a steel pipe fitting designed to connect pipes of different diameters in heating and plumbing systems. The coupling provides a transition from 22 mm to 15 mm, offering a compact solution for adapting or reducing run sizes in pressure installations where a robust carbon steel fitting is required. It is compatible with standard steel pipework and intended for use in systems that require durable metal connectors.

Advantages

The reduction coupling features solid steel construction that ensures mechanical strength and resistance to handling during installation. Its dimensional design provides a reliable, tight connection between 22 mm and 15 mm pipes, minimizing the risk of leaks when correctly installed. The coupling is suitable for use in pressurized systems and is designed to meet the demands of plumbing and heating environments where a stable metal transition is needed.

Suitable for

• Connecting 22 mm to 15 mm steel pipes in heating circuits
• Reducing pipe diameter in hot water and central heating systems
• Adapting existing pipework during renovations or modifications
• Pressure installations that require a carbon steel fitting

Key specifications

• Material: C-steel (carbon steel)
• Connection sizes: 22 mm → 15 mm
• Application: heating and plumbing systems
• Suitable for pressurized installations
• Design: reduction coupling for pipe diameter transition

How to use

Select the coupling that matches the outer diameters of the pipes to be joined (22 mm and 15 mm). Prepare pipe ends by deburring and cleaning to ensure proper fit and seal. Install the coupling according to the system practice: slide or thread the fitting onto the prepared pipe ends and use the appropriate joining method for carbon steel fittings in the installation (such as press, solder, or threaded joint) following manufacturer and system guidelines. After assembly, perform pressure testing according to relevant standards to verify leak-free connections.

Usage recommendations

Use compatible joining methods and gaskets approved for carbon steel pipework; avoid mixing incompatible metals without appropriate corrosion protection. Follow local regulations and industry standards for pressure testing and safe installation in heating and plumbing systems.
