## Long description

SANHA-THERM C-Stahl d42x35 pipe reducer coupling by SANHA is a steel concentric reducer designed to join pipes with outer diameters of 42 mm and 35 mm. Made for thermal and plumbing installations, the reducer provides a metal-to-metal transition between different pipe sizes and is intended for use in heating, hot water and cold water systems where a robust steel connection is required.
Advantages
The concentric design ensures a centred flow path and reduces flow disturbances when transitioning between pipe sizes. Constructed from steel, the coupling offers mechanical strength, resistance to pressure loads typical in heating and plumbing systems, and compatibility with steel piping assemblies. Its compact form factor simplifies installation in confined spaces and supports reliable, leak-free joints when installed according to standard joining methods for steel fittings.
Suitable for
 Domestic and commercial heating systems
 Hot water distribution lines
 Cold water piping networks
 Plumbing installations requiring a concentric steel reducer
Key specifications
 Type: concentric pipe reducer coupling
 Material: steel
 Connection: metal-to-metal joining with steel pipes
 Outer diameters: 42 mm to 35 mm transition
 Application temperature: suitable for typical heating and domestic water temperatures (follow system specifications)
 Pressure class: suitable for standard plumbing and heating pressures (verify with system requirements)
How to use
Prepare the mating pipe ends by cutting square and removing burrs and debris. Ensure surfaces are clean and free from corrosion or scale that could impair sealing. Align the 42 mm and 35 mm pipe ends concentrically with the coupling and perform the appropriate joining method for steel fittings used in the installation (for example, welding, brazing or approved mechanical joining technique), following applicable codes and manufacturer guidance. After joining, inspect the joint for proper alignment and test the system for leaks and pressure performance according to relevant standards.
Usage recommendations
Use the reducer within the temperature and pressure limits of the overall system; consult system documentation for compatibility. When used in potable water systems, confirm that materials and joining methods meet local regulations. For long-term reliability, protect exposed steel fittings from corrosion where necessary and follow routine inspection and maintenance schedules for heating and plumbing installations.
