Coupling reducer SANHA THERM C-Stahl d35x28 – copper-to-steel pipe connector

SANHA THERM C-Stahl reducing coupling d35x28 is a pipe fitting designed to join a 35 mm pipe to a 28 mm pipe, providing a secure transition between compatible copper and steel piping systems. Intended for heating and plumbing installations, the coupling allows a reliable diameter reduction while maintaining flow integrity and mechanical stability in mixed-material pipelines.

Advantages

The SANHA THERM C-Stahl coupling offers a compact, space-saving solution for diameter reduction between 35 mm and 28 mm pipes. Its design ensures consistent mechanical connection and alignment between copper and steel pipes, reducing the need for additional adapters. The fitting is suitable for press or soldering installation methods depending on system requirements and provides stable hydraulic performance with minimal pressure loss across the reduction.

Suitable for

• Heating systems combining copper and steel pipelines
• Plumbing installations requiring diameter transitions from 35 mm to 28 mm
• Repair or retrofit projects where mixed-material connections are needed
• Commercial and residential distribution lines with standard thread or press connection methods

Key specifications

• Nominal pipe diameters: 35 mm reduced to 28 mm
• Material compatibility: copper to steel connection
• Application: heating and plumbing systems
• Function: mechanical coupling for diameter reduction
• Typical installation methods: press-fitting or soldering depending on system design

How to use

Select the appropriate installation method for the SANHA THERM C-Stahl reducing coupling according to the project specifications and local codes. Prepare pipe ends by cutting square, deburring, and cleaning contact surfaces. Position the coupling to ensure correct insertion depth for both 35 mm and 28 mm pipes, then complete the joint using the chosen technique (press or solder) following the manufacturer's and relevant standards' instructions. After installation, verify alignment and pressure integrity according to system testing procedures.

Usage recommendations

Ensure material compatibility in the overall pipeline and confirm that the coupling's specified diameters match the installed pipes. Observe applicable installation standards and perform pressure testing after assembly. For long-term corrosion protection and optimal performance in mixed-metal systems, consider appropriate insulation, dielectric separation, or corrosion inhibitors where required by the installation context.
