Provides mechanical transition between sizes and is intended for use in potable water, heating circuits, and industrial installations where compatible materials and pressure ratings apply.

## Long description

SANHA-THERM C-Stahl reducer coupling d22x18 from SANHA is a steel pipe fitting engineered to join a 22 mm pipe to an 18 mm pipe. It provides a reliable mechanical transition between different pipe diameters in potable water, heating and circulation systems, and compatible industrial installations. The fitting is suitable for systems that require a durable steel connection and where the material properties of carbon steel meet system requirements.
Advantages
The SANHA-THERM C-Stahl reducer coupling offers robust mechanical strength typical of steel fittings, ensuring a stable connection under thermal and hydraulic stress. Its compact design saves installation space while enabling a smooth diameter change that minimizes flow disturbance. The coupling's material compatibility allows use in heating circuits and potable water systems when system specifications and corrosion protection measures are met.
Подходит для
 Системы отопления и циркуляционные контуры
 Холодное и горячее питьевое водоснабжение при соответствии требований по материалам
 Промышленные трубопроводы с совместимыми рабочими параметрами
 Места с ограниченным пространством, где требуется уменьшение диаметра
Key specifications
 Material: carbon steel (C-Stahl)
 Connection: reducer coupling for direct mechanical joining of two pipe diameters
 Nominal diameters: 22 mm to 18 mm
 Application temperature range: suitable for typical heating and potable water temperatures when used within system limits
 Typical use environments: domestic heating, hot water circulation, industrial installations with compatible media
How to use
Install the reducer coupling by preparing pipe ends according to the chosen joining method and system requirements. Ensure pipes are cut square, deburred and cleaned to achieve correct seating. Fit the 22 mm pipe to the larger end and the 18 mm pipe to the smaller end, and secure the connection following the installation procedure for steel fittings in the given system (for example, welding, brazing, or using the specified mechanical joining method). Verify alignment, test for leaks, and commission the system according to applicable standards.
Usage recommendations
Confirm material compatibility and pressure/temperature ratings with the overall system design before installation. Apply appropriate corrosion protection and follow local codes and manufacturer instructions for joining steel fittings and for potable water or heating applications.
