How can flanges be classified based on Pressure- temperature ratings?
Answer:
Flanges are classified based on pressure temperature ratings as: –
A. 150#
B. 300#
C. 400#
D. 600#
E. 900#
F. 1500#
G. 2500#
Pressure temperature rating carts in the standard ASME16.5 specify the non-shock working
gauge pressure to which the flange can be subjected to at a particular temperature.
IN GENERAL,
RATINGS 150 300 ARE TERMED AS LOW PRESSURE RATINGS
RATINGS 400 600 900 ARE TERMED AS INTERMEDIATE PRESSURE RATINGS
RATINGS 1500 2500 ARE TERMED AS HIGH PRESSURE RATINGS
