## Summary description

Reducing coupling SANHA SANHA-THERM C-Stahl d54x28 designed for joining pipes with different diameters (54 mm to 28 mm). Manufactured for use in heating and plumbing installations, this C-Stahl reducer provides a reliable mechanical transition between pipe sizes. Suitable for connecting carbon steel piping where downscaling of pipe diameter is required.

## Long description

Reducing coupling SANHA SANHA-THERM C-Stahl d54x28 stainless steel carbon steel is a mechanical reducer designed to join pipes of different diameters — from 54 mm to 28 mm. Manufactured for heating and plumbing systems, the coupling enables a secure transition between larger and smaller carbon steel pipes while maintaining a compact footprint. The product is intended for use where a reliable, durable connection is required in installations subject to typical domestic and commercial heating system conditions.
Advantages
The SANHA-THERM C-Stahl reducing coupling provides a stable mechanical connection between differing pipe diameters without the need for complex fittings. Constructed from compatible metals for carbon steel piping, it ensures structural integrity under standard operating pressures and temperatures common for heating circuits. Its straightforward geometry simplifies installation and reduces assembly time compared with more elaborate joining methods.
Suitable for
 Reducing pipe diameter in heating system supply and return lines
 Plumbing installations requiring transition between 54 mm and 28 mm pipes
 Repairs and retrofits of existing carbon steel pipe networks
 Mechanical connections in boiler room and utility piping
Key specifications
 Material: stainless steel and carbon steel compatible construction for C-Stahl systems
 Connection type: reducing coupling for mechanical joining of two pipe ends
 Nominal diameters: 54 mm (larger end) and 28 mm (smaller end)
 Application: designed for heating and plumbing installations
 Design: compact reducer profile suitable for inline installation
How to use
Select the coupling size matching the pipe outside diameters (54 mm and 28 mm). Prepare pipe ends by cleaning and deburring to ensure full contact and proper fit. Slide the appropriate ends of the pipes into the coupling until they seat fully, following any manufacturer guidance for alignment and insertion depth. Complete the mechanical fastening or sealing method recommended for the installation — for example, welding, threaded adapters, or compatible clamps — according to system requirements and applicable regulations. Check for alignment and tightness before returning the system to service.
Usage recommendations
Use this reducer only with carbon steel piping and in systems rated for the coupling's material compatibility. Verify operating pressure and temperature limits for the overall system and follow local codes for heating and plumbing installations. Inspect joints after installation and periodically during service for signs of wear, corrosion, or leakage.
