Pipe reducer coupling SANHA SANHA-THERM C-Stahl d35x22, steel, dimensions 35 × 22 mm

The SANHA-THERM C-Stahl d35x22 reducer coupling is a steel pipe fitting designed to connect pipes with outer diameters of 35 mm and 22 mm. Manufactured by SANHA for use in heating and plumbing systems, this coupling establishes a reliable transition between two different pipe sizes in steel piping networks. It is intended for installations where a durable mechanical connection between larger and smaller steel pipes is required for fluid or thermal distribution.

Advantages

This reducer coupling is made from steel, offering mechanical strength and resistance to the temperatures and pressures typically encountered in heating and plumbing applications. Its concentric design provides a smooth diameter transition that minimizes flow disturbance and simplifies installation compared with more complex adaptors. The coupling is compatible with conventional joining methods used in steel piping systems and is suitable for fixed, permanent connections where dimensional stability is important.

Suitable for

• Residential and commercial heating systems
• Hot and cold water plumbing lines
• Steel pipe networks requiring size transitions from 35 mm to 22 mm
• Replacement or retrofit work in existing steel piping installations

Key specifications

• Material: steel
• Design: concentric reducer coupling
• Connection diameters: outer diameters 35 mm → 22 mm
• Application: heating and plumbing distribution lines
• Suitable for use with fluid and thermal media within typical system ratings

How to use

Prepare the mating pipe ends by ensuring they are clean, free of scale, burrs and any contaminants. Align the larger and smaller pipes concentrically with the coupling and use the appropriate joining method for steel fittings applied in your system (for example, welding, soldering, brazing or mechanical fastening) following manufacturer and local regulations. Verify alignment and secure the joint to maintain correct flow direction and system integrity. After joining, inspect the connection for leaks and perform pressure testing in accordance with applicable codes.

Usage recommendations

Choose the joining technique compatible with the coupling material and the installation’s operating temperature and pressure. When working on heating systems, ensure the system is depressurized and cooled before making connections. Use appropriate personal protective equipment and follow local plumbing and heating standards for testing and commissioning.
