SANHA 45° nickel-plated return bend (Łuk nyplowy) ZWxZZ 28 pipe fitting

SANHA 45° nickel-plated return bend (Łuk nyplowy) ZWxZZ 28 is a 45° pipe fitting with a nominal diameter of 28 mm designed for changing flow direction in heating, cooling and potable water systems. The fitting is nickel-plated to provide a corrosion-resistant surface and a smooth contact area suitable for soldering or other joining methods recommended by the manufacturer. Its compact return geometry saves installation space where a short angled return is required.

Advantages

The nickel-plated surface offers enhanced corrosion resistance and a durable finish that facilitates soldering and visual inspection. The 45° angle provides a gentle change of direction that reduces hydraulic losses compared with sharper bends. Its 28 mm nominal size is compatible with standard copper and compatible pipe systems, allowing reliable connection in common domestic and light-commercial installations.

Suitable for

• Residential and commercial heating circuits
• Cooling and chilled water lines
• Potable water distribution where compatible joining is required
• Tight or compact return runs where space is limited

Key specifications

• Material: nickel-plated fitting body with metal base suitable for thermal joining
• Nominal diameter: 28 mm
• Bend angle: 45°
• Connection type: smooth ends designed for soldering or manufacturer-specified joining methods
• Finish: nickel plating for corrosion resistance and ease of cleaning

How to use

Prepare pipe ends by cutting square, deburring and cleaning the surfaces to be joined. Position the ZWxZZ 28 return bend to achieve the required 45° directional change and ensure correct alignment with the adjoining pipe run. Apply the approved joining method for this nickel-plated fitting, such as soldering or the SANHA-recommended technique, following applicable codes and safety practices. Allow joints to cool and inspect visually for complete wetting and a uniform joint before pressure testing the system according to installation standards.

Usage recommendations

Use appropriate flux and heat control when soldering nickel-plated surfaces to avoid overheating the plating; verify compatibility of solder and flux with nickel finishes. Follow local regulations and SANHA guidelines for pressure testing and system commissioning.
