USA Manufactured Black Cast Iron Pipe 250# Companion Flange

USA Manufactured Black Cast Iron Pipe Companion 250# Flange

USA Manufactured Black Cast Iron Pipe Companion 250# Flanges provide a durable and serviceable connection between threaded piping and higher-pressure flanged valves, pumps, strainers, meters, tanks, and industrial equipment. Manufactured in the United States from quality black cast iron, these fittings typically combine a precision-machined threaded pipe opening with a drilled 250-pound-class flange face.

The companion flange threads onto compatible male NPT pipe or pipe nipples and connects to a matching 250# flange using a properly selected gasket, bolts, and nuts. This threaded-to-flanged configuration creates a removable mechanical joint that simplifies installation, inspection, maintenance, and equipment replacement without cutting the connected piping.

Heavy-Duty 250# Flanged Connection

Black cast iron provides excellent rigidity, dimensional stability, and resistance to ordinary mechanical wear. USA manufactured black cast iron 250# companion flanges feature heavier construction and a more substantial flange pattern than comparable 125# fittings. Accurately positioned bolt holes and dependable flange-face dimensions support proper alignment in demanding commercial and industrial piping systems.

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