This specification provides design and construction criteria for large diameter flanges for use in high temperature, low pressure service such as internal combustion engine exhaust and forced ventilation systems. The flanges shall be classified according to types as follows: Type I and Type II. Number of holes, hole diameter, and bolt circle are identical for both Type I and Type II flanges. Drilling of flanges shall be in accordance with the specified requirements.
