## Summary description

SANHA-THERM C-Stahl reducer coupling by SANHA, size 42x22 mm, designed for joining steel pipes with different diameters. Manufactured for reliable mechanical and hydraulic connection in heating and plumbing systems, it enables transition from 42 mm to 22 mm piping. Suitable for use in commercial and residential installations where durable steel pipe fittings are required.

## Long description

The SANHA-THERM C-Stahl reducer coupling 42x22 mm is a steel pipe fitting designed to connect two steel pipes of different diameters in heating and plumbing systems. Engineered by SANHA for mechanical and hydraulic reliability, this reducer enables a secure transition from a 42 mm supply or distribution line to a 22 mm branch or fixture connection. The component is intended for installation where durable steel fittings are required for commercial or residential piping networks.
Advantages
This reducer coupling provides a robust connection between differing pipe sizes with corrosion-resistant steel construction suitable for hot-water and heating applications. It ensures a tight mechanical seal when installed according to manufacturer guidelines, minimizing the risk of leaks and pressure loss. The coupling's standardized dimensions allow integration with common steel pipework and make it compatible with typical system layouts used by professionals.
Suitable for
Transitioning from 42 mm main lines to 22 mm branches in heating systems
Steel plumbing installations in residential buildings
Commercial piping where durable steel couplings are required
Repairs or retrofits that require a change of pipe diameter
Key specifications
Material: steel suitable for heating and plumbing use
Connection type: reducer coupling for joining two pipe diameters
Outer diameter sizes: 42 mm to 22 mm transition
Application: mechanical and hydraulic connection in plumbing and heating systems
Compatibility: intended for use with steel pipe systems of corresponding diameters
How to use
Prepare the steel pipes by cutting squarely and removing burrs and scale. Ensure pipe ends are clean and free of debris. Slide the reducer coupling onto the larger pipe end and align with the smaller pipe; follow the appropriate joining method for SANHA steel fittings—this may include mechanical pressing, welding, or using the specified assembly technique compatible with the coupling design. After assembly, verify alignment and fastening according to system pressure requirements and applicable codes. Conduct a pressure test or leak test as required by project standards before placing the system into service.
Usage recommendations
Use the reducer coupling only with steel pipes of matching outer diameters and within the temperature and pressure ranges specified for the piping system. Employ qualified personnel for installation and follow local regulations and standards for heating and plumbing installations. Regularly inspect joints in heating systems during commissioning and scheduled maintenance to ensure long-term reliability.
