Product information

Description

The SANHA-THERM C-Stahl reducing coupling d28x18 by SANHA is a mechanical pipe fitting designed to join steel pipes of two different diameters. Engineered for heating, plumbing and industrial steel piping systems, this reducer coupling offers a secure diameter transition from 28 mm to 18 mm while maintaining the mechanical integrity of the pipeline. The coupling is intended for use with compatible C-Stahl (carbon steel) pipe systems and provides a compact solution where space or layout requires a stepped connection.

Advantages

The reducer coupling ensures a reliable mechanical connection between a 28 mm and an 18 mm steel pipe without the need for welding on site. Its design supports stable alignment and pressure-tight performance when installed according to applicable standards. The compact form factor saves installation space and simplifies piping layouts by eliminating the need for more complex assemblies. Compatibility with SANHA-THERM steel systems reduces the risk of mismatched materials and eases integration into existing heating and plumbing networks.

Suitable for

  • Heating system pipe runs requiring a transition from 28 mm to 18 mm
  • Plumbing installations in residential and commercial buildings
  • Industrial steel piping where a compact diameter reduction is needed
  • Retrofit or repair work on C-Stahl pipelines

Key specifications

  • Material: C-Stahl (carbon steel) compatible with SANHA-THERM systems
  • Connection type: reducing mechanical coupling for steel pipes
  • Dimensions: for use with 28 mm and 18 mm nominal pipe diameters
  • Application: suitable for heating, plumbing and general industrial steel piping
  • Form factor: compact inline reducer coupling

How to use

Select the appropriate pipe ends and ensure both the 28 mm and 18 mm steel pipes are cut square, de-burred and clean. Slide the coupling onto one pipe, align the second pipe into the opposite end and assemble according to SANHA-THERM installation instructions and applicable local codes. Tighten or secure the coupling using the specified method for the product family, and test the joint under the required system pressures. Follow safety procedures and use proper tools for steel pipe handling and joining.

Usage recommendations

Use the coupling in combination with SANHA-THERM compliant components to ensure material compatibility. Verify system pressure and temperature ratings before installation, and perform a pressure test after assembly. Store fittings in a dry environment to avoid surface corrosion prior to installation.
