ASTM B 564 UNS N04400 / Monel 400 Nickel Alloy Blind Flange BLRF Flange


The EN 1092-1 Type 35 weld ring neck is a collar, that is always used with a Type 02 loose plate flange. In such a flange assembly, its “neck” end is joined to the pipe by welding, while the loose plate flange mounts to the back surface of the “ring” shoulder, pressing it against the gasket to form a tight seal. EN 1092-1 Type 35 weld neck rings are available in p/T ratings of PN 2.5, PN 6, PN10, PN 16, PN 25 and PN 40. Generally, the Type 35 weld ring neck collar shall be manufactured by a forging process or by welding a ring plate to a seamless pipe.

The Advantage of using monel 400 material:

• Excellent resistance to corrosion in a wide range of environments, including seawater, acids, and alkalis.
• High strength and toughness, making it suitable for high-stress applications such as oil and gas production.
• Non-magnetic properties, making it useful in applications where magnetic interference could be a problem.
• Good weldability and fabrication properties, allowing for easy manufacturing and customization of flanges to suit specific applications.
• Resistance to stress corrosion cracking, which can be a problem in many other materials.
