In 2018, Wanhua Chemical and Daming Heavy Industry in Jingjiang, Jiangsu, signed several contracts for large-scale pressure vessel products for a new ethylene production project. The production of these vessels is time-consuming and challenging, especially when it comes to the two pyrolysis gas vapor dryers, whose manufacture is even more difficult. The pyrolysis gas vapor dryer is a Class III fatigue vessel with a diameter of 7500 mm, a wall thickness of 70 mm, a length of 22 meters, and a weight of 250 tons per unit. This equipment enabled Daming Heavy Industry to achieve several \"firsts\": the first time a fatigue vessel of such large diameter was manufactured, the first time grooves were machined entirely mechanically, and the first time heat treatment using the internal combustion method was applied.
