## Long description

Margo welding coupling MUFA SP 25 for socket welding DN 25 (1") is a steel coupling designed to create permanent welded connections in fluid and gas pipeline systems. The coupling is intended for socket welding, providing a compact and robust joint solution for plumbing, heating, and industrial piping where a leak-resistant welded connection is required. Constructed from steel, it is suitable for integration into welded pipelines that demand mechanical strength and long-term durability.
Advantages
This welding coupling offers a compact form factor that simplifies installation in confined spaces and ensures minimal protrusion beyond the pipe surface. Being designed for socket welding, it enables consistent, permanent joints with good alignment between pipe ends and coupling body. Its steel construction provides mechanical strength and resistance to pressures typical for plumbing and heating systems. The coupling’s design supports creating a tight, leak-resistant welded connection when installed by qualified welding personnel following relevant standards.
Suitable for
 Plumbing systems requiring welded pipe joints
 Domestic and commercial heating installations
 Industrial fluid and gas pipelines
 Repairs and retrofits where permanent welded connections are needed
Key specifications
 Type: Socket welding coupling
 Nominal diameter: DN 25 (1")
 Material: Steel
 Connection method: Socket welding for permanent welded joints
 Application: Fluid and gas pipelines, plumbing, heating, industrial systems
How to use
Prepare pipe ends by cutting square and cleaning to remove burrs, scale, and contaminants. Insert the pipe into the coupling socket to the required insertion depth, ensuring correct alignment. Perform socket welding according to applicable welding procedures and standards, using appropriate filler material and welding parameters for the steel type. After welding, allow joints to cool under controlled conditions and inspect welds visually and by nondestructive testing if required. Ensure system depressurization and flushing before commissioning the pipeline.
Usage recommendations
Use certified welding procedures and qualified welders when installing the coupling. Verify material compatibility, operating pressure, and temperature limits for the specific application, and apply corrosion protection or coatings as required by the installation environment.
