## Summary description

Margo MUFA SP 20 is a welding compression coupling designed for DN 20 (3/4") pipelines. The fitting serves to create a secure welded connection on metal piping systems, providing mechanical strength and sealing at the joint. Suitable for water, heating and industrial installations where a welded transition or repair is required.

## Long description

Margo MUFA SP 20 for welding is a compression coupling designed for DN 20 (3/4") metal pipelines. The fitting enables a welded joint that combines mechanical strength with a sealing interface, intended for use in water supply, heating and various industrial pipe installations. It is manufactured to provide a stable welded transition or repair point on metallic piping systems where a robust, permanently joined connection is required.
Advantages
The coupling offers a compact design that facilitates welding and alignment on pipes of nominal diameter 20 mm. Constructed for metal-to-metal welding, the fitting provides good mechanical resistance at the joint and supports a sealed connection after welding. Its form factor simplifies installation in confined spaces and allows for precise positioning prior to final welds.
Suitable for
Repairing or replacing sections of DN 20 (3/4") metal pipeline
Creating welded transitions in water supply systems
Connections in heating and radiator circuits
Industrial installations requiring durable welded joints
Key specifications
Nominal diameter: DN 20 (3/4")
Type: welding compression coupling for metal pipes
Application medium: cold and hot water, heating systems, general industrial fluids compatible with metal piping
Installation method: welded joint with compression interface for alignment
Suitable material type: metallic pipelines (steel, copper or similar metals compatible with welding)
How to use
Prepare pipe ends by cleaning and removing any corrosion, paint or oil to expose bare metal for welding. Position the coupling on the pipe ensuring correct alignment and adequate overlap according to the coupling geometry. Tack-weld the fitting to hold it in place, check alignment, then complete circumferential welding following appropriate welding procedure and safety standards for the pipe material. Allow welds to cool as specified for the base metal, then inspect the joint visually and by pressure testing or other leak tests suitable for the system.
Usage recommendations
Use appropriate welding consumables and parameters matched to the pipe material. Follow applicable codes and safety practices for welding on pressurized systems, and perform pressure testing after installation to confirm a leak-free connection. Where required, apply corrosion protection after welding and verify compatibility with the system medium.
