The pressure vessel BU mainly provides heavy vessels and Class I, II and III pressure vessels. The vessels’ quality has always been reliable and stable. The capacity of the plate-cold-rolling can reach 70mm and the plate-hot-rolling can reach 120mm. The thermal treatment capacity allows a vessel with a size of 17m *4m*3.6m* to be wholly processed. The crack-detection thickness is less than 200mm, and the lifting capacity reaches 100 tons, basically meeting the customers’ requirement for non-standard pressure vessels and heavy vessels.
