... discussion is made of Incoloy 800H; the metal temperature is about 800 °C (1475°F) at an internal gas pressure of 3.1 MPa (450 psi). The plant was taken into operation in 1969. In 1976 the bottom manifold showed severe bulging (up to 20% diametrical expansion) and creep damage. The cause of the damage...
