Zeron Fastners
Nickel Alloys Monel 400 Blind Flanges
Nickel Alloys Monel 400 Blind Flanges are solid disk pipe flanges used to close off the end of a piping system or a vessel opening. Zeron Fasteners manufactures and supplies these vital components from the resilient Monel 400 alloy (UNS N04400). The primary function of this product is to provide a complete, reliable shut-off for pipeline isolation, maintenance, or testing. The solid nature of the flange must handle the full pressure of the system, demanding high mechanical strength and integrity. Monel 400 is chosen for its exceptional resistance to corrosion in seawater and aggressive chemical processing streams. The primary application of these Monel 400 Blind Flanges is in high-pressure testing sections, temporary pipeline terminations, and closing off pump or valve nozzles in offshore, marine, and chemical industries.
