摘要
介绍国内首台6 000 m3丙烷球罐的设计要求及建造关键技术。球罐建造时采用先安装下支柱、吊装赤道带同时组焊上下支柱的拼装方法;在球罐内部采用三角架和弧梯铺钢铺板的方法搭建施工平台,简化工装并缩短了工期。通过对焊接和整体热处理等关键工序的有效控制,保证了球罐的安装质量。
The domestic first 6 000m3 propane spherical tank design requirements and construction key technology are introduced. Spherical tank is used when building install under support column, the equator zone hoisting for upper and under support column of assembled at the same time. Inside the spherical tank using a tripod and arc ladder steel deck method establish the platform construction,which saves time limit for a project, simplifies the tooling. Through welding process control management and the overall heat treatment operation key, effectively guarantee the quality of spherical tank installation.
