Copper-soldered single-cup socket SANHA SANHA-THERM C-Stahl d22, model 12408622

The Copper-soldered single-cup socket SANHA SANHA-THERM C-Stahl d22, model 12408622 is a single-socket fitting for joining 22 mm steel or copper pipe in hot-water and central heating systems. Manufactured for compatible soldered connections, this fitting creates a permanent, leak-tight joint when installed with standard soldering techniques. It is intended for use in residential and commercial plumbing and heating installations where a robust soldered connection is required.

Advantages

This copper-soldered single-cup socket provides a durable soldered joint that resists thermal stress and pressure typical of heating circuits. The design supports a clean, narrow joint profile that is compatible with common plumbing materials, simplifying assembly and reducing the need for mechanical sealing elements. Constructed to industry standards, the fitting facilitates reliable connections and long service life when properly installed by qualified personnel.

Suitable for

• Joining 22 mm steel piping in central heating circuits
• Connecting 22 mm copper pipe in hot-water distribution
• Residential and commercial heating and plumbing installations
• Applications requiring soldered, pressure-tight joints

Key specifications

• Connection type: single-cup (socket) for soldering
• Compatible pipe diameter: 22 mm
• Material: copper-soldered fitting suitable for C-steel and copper pipes
• Intended media: hot water and central heating fluids
• Application environment: heating and plumbing systems in buildings

How to use

Prepare the pipe ends by cutting square and removing burrs, then clean and flux both the pipe and the inside of the socket. Insert the pipe fully into the socket, ensure proper alignment, and apply solder using an appropriate flame or soldering tool until a continuous solder fillet is formed. Allow the joint to cool undisturbed and then inspect for complete penetration and a smooth solder profile. Pressure-test the circuit according to applicable standards before putting into regular operation.

Usage recommendations

Use appropriate flux and solder alloys recommended for copper-to-steel or copper-to-copper joints, and follow local codes and safety procedures. Installation should be carried out by trained personnel with suitable protective equipment and tools. Avoid excessive heat that could damage surrounding materials or coatings, and ensure the system is flushed and pressure-tested after installation.
