Flanged Threaded Neck Margo DN 40 0.6 MPa

The Margo flanged threaded neck DN 40, rated for a maximum operating pressure of 0.6 MPa, is a pipe connection component designed for installation in low-pressure fluid systems. It combines a threaded neck with a flange interface to provide a secure connection between pipes, valves or equipment where a DN 40 threaded flange is required. The design is intended for use in water supply, heating circuits and general industrial piping applications where a compact flanged threaded transition is needed.

Advantages

This flanged threaded neck provides a reliable mechanical connection with the convenience of a threaded interface and the sealing and mounting capabilities of a flange. Its DN 40 size and 0.6 MPa pressure rating make it suitable for typical low-pressure installations. The component simplifies assembly and maintenance by enabling bolted flange connections while retaining a threaded pipe joint. Constructed to standard flange dimensions and threaded connection geometry, it supports consistent alignment and leak-resistant sealing when installed with appropriate gaskets and fasteners.

Suitable for

• Low-pressure water distribution systems
• Residential and commercial heating circuits
• Industrial piping where DN 40 threaded flange connections are required
• Situations needing a transition between threaded pipework and flanged equipment

Key specifications

• Nominal diameter: DN 40
• Maximum pressure: 0.6 MPa
• Connection type: threaded neck with flange interface
• Application: water, heating, and general low-pressure industrial piping
• Mounting: bolted flange connection compatible with standard gaskets and fasteners

How to use

Install the flanged threaded neck by first ensuring the mating flange and threaded pipe are clean and free of debris. Apply an appropriate thread sealant or tape to the threaded joint as required by the system standard, then hand-tighten and finish to the recommended torque for the thread type. Position a gasket between mating flanges and align bolt holes before inserting fasteners. Tighten flange bolts in a cross pattern to achieve uniform compression of the gasket and to prevent leakage. Verify the assembly for leaks at operating pressure and perform routine inspections as part of standard maintenance.

Usage recommendations

Use compatible gaskets and stainless or suitably rated fasteners to match the operating environment. Avoid exceeding the maximum pressure of 0.6 MPa and ensure system temperature and fluid chemistry are compatible with the component materials. Follow local codes and industry standards for flange bolting and thread sealing during installation.
