## Summary description

Welding coupling Margo DN 50 (model MUFA SP 50) designed for permanent steel pipe connections. The fitting is intended for in-line butt welding to join pipes with a nominal diameter of 50 mm (DN 50). Typical applications include water supply, heating, and industrial piping where a welded, pressure-resistant joint is required.

## Long description

The Margo welding coupling DN 50 (MUFA SP 50) is a steel butt-weld fitting engineered for permanent pipe connections with a nominal diameter of 50 mm. Designed for in-line welding, this coupling provides a continuous, pressure-resistant joint suitable for water supply, heating circuits and industrial piping systems. The MUFA SP 50 is intended for applications where a welded connection is preferred over threaded or flanged joints to ensure strength, durability and leak-free performance under typical operating conditions.
Advantages
The MUFA SP 50 coupling offers a robust steel construction that enables a long service life when welded correctly. Its design simplifies alignment for butt welding, ensuring a smooth internal bore and minimal flow disturbance after installation. By creating a permanent welded joint, the fitting reduces maintenance needs and eliminates potential leak points associated with mechanical couplings or seals. The product is compatible with standard DN 50 piping and can be used in systems operating under routine temperature and pressure ranges common to water supply, heating and many industrial processes.
Suitable for
 Water supply pipelines with nominal diameter DN 50
 Heating systems and circulation loops
 Industrial process piping requiring welded joints
 Permanent installations where pressure-resistant connections are needed
Key specifications
 Material: steel construction suitable for welding
 Connection type: butt welding (in-line weld)
 Nominal diameter: DN 50 (50 mm)
 Application: pressure piping for water, heating and industrial systems
 Joint type: permanent welded coupling providing a continuous internal bore
How to use
Prepare pipe ends by cutting square and removing burrs, ensuring proper fit-up with the MUFA SP 50 coupling. Align pipes concentrically within the coupling and tack-weld to maintain position. Perform full circumferential butt welds according to relevant welding procedure specifications and standards for the pipe material. After welding, inspect welds visually and with non-destructive testing as required by project or regulatory standards, and remove any slag or spatter to restore a smooth internal and external surface.
Usage recommendations
Use certified welding procedures and qualified welders for installation. Select welding consumables and pre-/post-weld heat treatment based on the base material and operating conditions. Follow applicable codes and safety practices to ensure a pressure-resistant and durable joint; inspect welded connections before commissioning the system.
