James Duva supplies high hub flanges. Much like a traditional blind flange – the high hub blind flange is used to close ends of piping systems, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed It is a round plate with no opening and bolt holes surrounding the parameter.
The high hub blind flange is available in various sizes and materials. A hub is required to maintain B16.5 rating on a modified blind flange. A “high hub” provides extra material for machining.
High hub flanges are used in quick assembly to save on cost. Valves are often located far from work needs to be done. Possibly from miles away! A high hub blind flange allows for the stopping of fluid and gases much closer to the job site. Valves are known to stick and be quite expensive to replace. By avoiding the valve, the cost of the job and hassle is much reduced. The most ideal way to bypass the valve is by using a blind flange.
Stainless steel high hub blind flanges are best known for their performance, durability, and resistance to corrosion caused by various materials and applications. They are ideal for chemical, petroleum, marine, paper making, shipbuilding, metallurgy, boiler, electric, power, and natural gas applications
Since the maximum stress in a high hub blind flange bending stresses at the center, they are safely allowed to be higher than in other types of flanges.
