Description

Cast Steel Pressure Relief Hoods – Model 53-OS-250, ANSI 250# Flanged

Description:

The 53-OS-250 Cast Steel Pressure Relief Hood is a robust outlet accessory designed for use in pressure relief systems on tanks, pipelines, or vent stacks. Constructed from durable cast steel, the hood is coated with red oxide primer to enhance resistance against corrosion in outdoor or industrial environments. The unit features an ANSI 250# flanged connection (estimated rating) for secure attachment to mating flanged components. This design helps deflect and safely direct vented gases or fluids away from critical equipment or personnel areas. Commonly used in refineries, storage depots, and chemical plants, this model is identifiable by its cast marking “53-OS-250”, typically found on the body.
