Socket welding coupling Margo MUFA SP 32 DN 32 (5/4) for pipe joining

Socket welding coupling Margo MUFA SP 32 DN 32 (5/4) for pipe joining is a metal fitting designed to create permanent, welded connections between pipes of nominal diameter DN 32 (5/4). Engineered for applications where a fixed, pressure-resistant joint is required, this coupling enables a flush fit that is welded in place to form a continuous pipeline. Its construction suits fluid and gas distribution systems in residential, commercial, and light industrial installations.

Advantages

The socket welding coupling provides a secure, permanent joint through welding, minimizing the risk of leaks compared to threaded or push-fit connections. Its flush design simplifies alignment and reduces flow disturbances at the joint. Made for standard DN 32 pipes, the coupling supports reliable mechanical strength and pressure resistance once correctly welded. The simple geometry of the fitting facilitates welding by qualified personnel and results in a smooth internal bore after finishing.

Suitable for

• Permanent welded connections in water supply and heating systems
• Gas distribution lines where welded joints are required
• Industrial piping systems with DN 32 (5/4) pipes
• Pipelines subject to pressure where a fixed, leak-resistant joint is needed

Key specifications

• Nominal diameter: DN 32 (5/4)
• Type: socket welding coupling
• Connection: designed for permanent welded joint (socket weld)
• Application: fluid and gas piping systems
• Installation: welded in place; flush internal profile for reduced flow disturbance

How to use

Prepare pipe ends by cutting square and deburring to ensure a proper fit into the socket. Position the pipes into the coupling so the required penetration depth is achieved and alignment is maintained. Perform welding following applicable welding procedures and standards for the pipe material, ensuring correct heat input and weld quality. After welding, inspect and, if required, carry out post-weld treatments such as grinding, non-destructive testing, or coating to meet the installation specifications.

Usage recommendations

Use qualified welding personnel and appropriate welding procedures for the pipe material in your system. Verify compatibility of parent pipe material and any coatings; follow local codes and pressure ratings when installing the coupling in water, heating, or gas systems.
