摘要

在大壁厚不锈钢复合板压力容器的建造过程中，通过深入研究其技术要点和难点，优化焊接接头结构设计，成功形成了一套完整的新型建造关键技术。这套技术不仅优化了焊接接头结构，还创新了一系列施工方法，包括筒体加热卷制、接头坡口机加工、接管内壁耐蚀层TIG/FCAW自动堆焊、不锈钢衬管液氮冷套、球形封头内壁耐蚀层带极埋弧堆焊、纵环缝窄间隙埋弧自动焊以及管口接头马鞍型埋弧焊等。这些新型建造关键技术的应用，在提高压力容器质量效果的同时，也带来了显著的经济效益，为行业同类型设备的建造提供借鉴。在未来的研究中，可以进一步探索这些技术在其他领域的应用，以实现更广泛的技术交流和合作。同时，对于大壁厚不锈钢复合板压力容器的建造，仍需不断深入研究其材料特性、工艺参数和施工方法，以不断提高设备的性能和安全性。

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 innovates 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 nitrogen cooling sleeve

spherical head inner wall corrosion-resistant layer strip electrode submerged arc overlay welding

longitudinal ring seam narrow gap submerged arc welding

and saddle type submerged arc welding of the pipe joint. The application 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 future 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 construction methods in order to continuously improve the performance and safety of the equipment.
