## Summary description

Reducing tee SANHA SANHA-THERM C-Stahl d18x18x15 is a C-Steel plumbing fitting designed to join three pipes with two equal 18 mm outlets and one reduced 15 mm branch. Intended for steel piping systems, it provides a reliable threaded or welded/press connection (depending on system) for distribution, branching and reduction of fluid flow in heating, cooling or potable water installations.

## Long description

Reducing Tee SANHA SANHA-THERM C-Stahl d18x18x15 for steel pipe connections is a C-steel plumbing fitting engineered to connect three steel pipes where two outlets share an 18 mm diameter and the branch reduces to 15 mm. Designed for use in heating, cooling and potable water systems, the fitting enables a change of flow direction and a reduction in pipe size while maintaining mechanical strength and corrosion resistance typical of SANHA C-Steel components.
Advantages
The fitting provides a compact, robust solution for branching and downsizing steel piping runs. Its homogeneous C-steel construction ensures stability under thermal cycling and pressure variations common in closed-loop systems. The product is made to integrate with SANHA-THERM installation methods, allowing secure threaded, welded or press-type joints depending on the selected system and installation practice. The tee supports reliable hydraulic performance with minimal internal flow disturbance at the junction.
Suitable for
Heating manifolds and radiator branches in residential and commercial systems
Cooling circuits and chilled-water distribution
Potable water distribution where steel pipe fittings are specified
Places where pipe diameter reduction from 18 mm to 15 mm is required
Key specifications
Material: C-Steel (SANHA C-Steel grade)
Connection configuration: reducing tee with two equal run outlets and one reduced branch
Outlet diameters: main run 18 mm, branch 15 mm
Application: plumbing and HVAC systems (heating, cooling, potable water)
Compatibility: designed for steel pipe systems and SANHA-THERM connection methods
How to use
Select the reducing tee matching the pipe diameters and the selected SANHA-THERM connection method. Prepare pipe ends according to the chosen joining method — clean and deburr for welding, ensure correct wall preparation for press connections, or follow threading procedures for compatible threaded systems. Insert or align the pipes into the tee, complete the joint using the specified welding, pressing tool or thread sealing method, and verify alignment and seal integrity. After installation, perform system pressure testing and check for leaks according to applicable standards.
Usage recommendations
Use appropriate personal protective equipment and follow SANHA and local regulations for steel pipe handling and jointing. Verify material compatibility with system fluids and operating temperatures, and ensure proper support and expansion allowances where thermal cycling is expected.
