USA Manufactured Black Cast Iron Pipe 250# Blind Flange

USA Manufactured Black Cast Iron Pipe 250# Blind Flange

USA Manufactured Black Cast Iron Pipe 250# Blind Flanges provide a durable, heavy-duty solution for closing the end of flanged piping systems, valve connections, equipment ports, vessel nozzles, and process lines. Manufactured in the United States from quality black cast iron, these solid industrial flanges contain no center opening and bolt directly to a compatible 250-pound-class flange.

The solid-face design creates a secure piping closure while preserving convenient access for future inspections, pressure testing, system cleaning, repairs, or piping expansion. Unlike a permanently welded cap, a bolted blind flange can be removed without cutting pipe or altering surrounding equipment. Accurately drilled bolt holes promote dependable alignment with matching 250# flange patterns.

Heavy-Duty 250# Flange Construction

Black cast iron provides excellent rigidity, dimensional stability, and resistance to ordinary mechanical wear. USA manufactured 250# black cast iron blind flanges feature heavier construction and a more substantial bolt pattern than comparable 125# flanges, making them suitable for demanding commercial and industrial piping installations.

The 250# designation identifies the flange pressure class and dimensional configuration. It should not automatically be interpreted as a maximum working pressure of exactly 250 PSI. Actual pressure capability depends on flange size, material, operating temperature, gasket selection, bolt specifications, connected components, and applicable system standards.
