Wanhua Ethylene Distillation Tower Project

The 1028 tons stainless steel ethylene distillation tower of Wanhua Yantai Industrial Park Phase II 1.2 million/year ethylene project and the first tower of Fujian Industrial Park gasification project manufactured by Daming Heavy Industries were delivered ahead of schedule at the same time.The 1.2 million/year ethylene project is the core of more than 20 projects in Wanhua Yantai Industrial Park Phase II. Among them, the ethylene distillation tower equipment, as the largest stainless steel tower in Wanhua Yantai Industrial Park, is the core static equipment of the ethylene plant, with a diameter of 6.6 meters, wall thickness of 46 mm, length of 107 meters, and weight of 1028 tons.

Aby bylo možné dokončit dodávku s vysokou kvalitou a účinností, přikládala společnost Daming Heavy Industry projektu destilační věže na začátku výběrového řízení velký význam, objednala hlavní ocelový plech hned napoprvé a využila dobrých vztahů s ocelárnou, aby zajistila, že ocelový plech dorazí o měsíc dříve, než bylo plánováno.

During the manufacturing process, relying on the Group’s manufacturing integration advantages, coordinating with sister company Daming Jingjiang Processing Center to process the main plate on schedule, and giving full play to the processing strength of the unique domestic weld mechanical root cleaner to greatly shorten the weld root cleaner cycle and ensure the welding quality, and the weld pass rate of one shot is as high as 99%.

The early delivery of this project is also inseparable from the day and night perseverance of the various departments of Daming Heavy Industry, and actively overcome various difficulties, boosting the smooth development of the work, so that the project was completed 15 days ahead of schedule and reached the high-quality requirements, which is of milestone significance for Daming Heavy Industry, and also marks a new level of Daming’s overall equipment manufacturing capacity!

Daming Heavy Industries Manufacturing Pressure Vessels Exported to Japan Successfully

Recently, Daming Heavy Industries’ Process Equipment Branch, in cooperation with Mitsui & Co. successfully shipped the pressure vessel export project for Hitachi Zosen Corporation, establishing a solid foundation for the subsequent development of the Japanese market.
The project consisted of 6 sets of equipment with the maximum size of 9.2m*9.2m*10m. Daming Heavy Industry Process Equipment Branch gave full play to the advantages of Jingjiang base in terms of plant, equipment processing capacity and sea transportation, which greatly ensured the smooth completion of the project.

In order to solve the problem of welding deformation of ultra-thin plate and the extremely strict high requirements and standards of Japanese customers, the relevant departments of Daming’s project team cooperated with each other and delivered the project in an orderly manner and on time, and finally submitted a satisfactory answer for the customers.

The smooth progress of this pressure vessel export project has once again witnessed the recognition of Daming Heavy Industry’s project management and manufacturing capability by the Japanese high-end market customers, and Daming Heavy Industry is confident to continue practicing the concept of “customer-centeredness” and providing customers with satisfactory services with high standards, high specifications and high quality.
