Estimation of residual life of boiler tubes using …

1/4/2013 · The residual life of service exposed platen super heater boiler tube of T22 material is estimated using oxide scale thickness, average metal temperature and creep master curve. While the oxide scale thickness is obtained using a Non-Destructive Ultrasonic technique, average metal temperature is calculated using one dimensional steady state heat transfer equations.

25/5/2021 · ASME Boiler & Pressure Vessel Code (Section I) has adopted Boardman's formula: P/S = 2t/ (D-0.8t) with y = 0.4. Indian Boiler Regulations has adopted a formula where the Inside Diameter of Membrane formula is replaced by the average Diameter. This formula is, therefore, known as Average formula, and is presented as P/S = 2t/ (D-t) with y = 0.5.
