    Presents a state of the art for design and construction of ultra thick pressure vessels for coal liquefaction and for petroleum refining processes subjected to similar conditions. This publication is divided into five subject categories:

    • Overview of Properties of 2-1/4 Cr-1Mo Plates and Castings

    • Design Consideration in Application of 2-1/4 Cr-1Mo Steel for Thick-Wall Pressure Vessels

    • Fabrication, Welding, and Cladding of Heavy-Gage 2-1/4 Cr-1Mo steel for Pressure Vessel Applications

    • Studies of Heat Treating

    • Temper Embrittlement of 2-1/4 Cr-1Mo Steel.
