Detailed

Product overview

Pressure vessel plates are specifically for fabricating vessels for storage and transportation in petroleum, chemistry industries and gas separation as well as other similar applications, such as various vertical vessel, heat exchanger, storage tanks, tank wagons etc. In view of the working environment and processing technology of the pressure vessels, the steel plates must have good cold bending & welding properties, with superior plasticity and toughness as well as high temperature short-time (or long-term) strength.
