Abstract
In the construction process of large walled stainless steel composite plate pressure vessels,a complete set of new construction key technologies has been successfully formed through in-depth research on its technical points and difficulties,optimization of welding joint structure design.This technology not only optimizes the welding joint structure,but also inno-vates a series of construction methods,including cylinder heating and rolling,joint groove machining,TIG/FCAW automatic overlay welding of the corrosion-resistant layer on the inner wall of the connecting pipe,stainless steel lined pipe liquid ni-trogen cooling sleeve,spherical head inner wall corrosion-resistant layer strip electrode submerged arc overlay welding,lon-gitudinal ring seam narrow gap submerged arc welding,and saddle type submerged arc welding of the pipe joint.The appli-cation of these new key construction technologies not only improves the quality and effectiveness of pressure vessels,but also brings significant economic benefits,providing reference for the construction of similar equipment in the industry.In fu-ture research,the application of these technologies in other fields can be further explored to achieve broader technological exchange and cooperation.At the same time,for the construction of pressure vessels with large wall thickness stainless steel composite plates,it is still necessary to continuously study their material characteristics,process parameters,and construc-tion methods in order to continuously improve the performance and safety of the equipment.关键词
