## Long description

Margo welding socket MUFA SP 40 is a prefabricated socket designed for welded in-line installation in piping systems with a DN 40 (6/4) connection size. The component provides a fixed socket interface for creating a welded branch or repair point on existing metal or compatible thermoplastic pipes. It is intended for applications where a reliable, permanently welded outlet is required and where standard DN 40 connections must be integrated into industrial or utility pipelines.
Advantages
The welding socket offers a ready-made solution that simplifies the process of adding a DN 40 outlet without fabricating custom fittings on site. Its design ensures a consistent welding surface and positioning for secure fusion or welds, reducing installation variability. The socket is suitable for both new installations and repair interventions, facilitating durable connections that maintain pipeline integrity and flow characteristics when installed according to recommended welding practices.
Suitable for
 Creating a welded DN 40 branch on steel or compatible thermoplastic pipelines
 Repairing or replacing a damaged section by adding a welded outlet
 Industrial process pipelines requiring a permanent tap-off point
 Utility and service lines where a fixed DN 40 connection is needed
Key specifications
 Connection size: DN 40 (6/4)
 Type: welding socket for in-line installation
 Material compatibility: metal and compatible thermoplastics suitable for welding
 Application: branch creation or repair point in piping systems
 Installation method: welded/fused to the main pipe
How to use
Prepare the main pipe by cutting and cleaning the area where the socket will be welded. Position the Margo MUFA SP 40 on the prepared section, ensuring correct alignment and orientation for the DN 40 outlet. Perform the welding or fusion according to the material-specific procedure and certified welding parameters, maintaining proper heat input and bead formation to achieve a leak-free joint. After welding, inspect the joint visually and, if required, perform pressure or non-destructive testing to verify integrity before placing the pipeline back into service.
Usage recommendations
Follow applicable welding standards and safety procedures for the pipe material in use. Use qualified personnel for welding or fusion operations, and verify material compatibility and welding parameters to ensure a durable, leak-tight connection. Consider corrosion protection or coating if the installation environment requires additional surface protection.
