Abstract: A pressure vessel with corrosion resistant lining and inexpensive overall is constructed in two steps. First a thinwalled vessel is prepared from integrally clad plate by conventional means, the cladding thus being of controlled quality, thickness and well bonded to the backing metal. Then the thickness of the backing metal is built up to the desired dimension preferably by electroslag deposition in the continuous casting process. The electroslag layer bonds to the backing layer without penetrating to the inner layer, and thus preserves the corrosion resistance of the lining. Heavy tube sheets are prepared in similar manner by depositing additional backing metal behind a clad metal plate.
