传统的空间错位钢管(特别是不同直径的两个管口)对接均采用放样操作,费时,费工又费料。本技术应用于任意两个直径在三维空间任意方位的对接钢管,接口采用焊接形式,连
The traditional space misalignment steel pipe (especially two different diameter pipe nozzle) are lofted operation, time-consuming, laborious and costly. This technology is applied to any two butt pipes with any diameter in any position in three-dimensional space. The interface adopts the welding mode
