Description
技术领域technical field
本发明涉及一种钢制管无缝连接机构及方法。The invention relates to a steel pipe seamless connection mechanism and method.
背景技术Background technique
目前，钢制管连接多用法兰、螺栓和密封垫等连接，其中法兰与钢制管焊接，两侧法兰中间加密封垫，实现钢制管的连接。这种连接方式使得钢管之间存在间隙，用封闭的钢制管管道研究颗粒输送实验时，此间隙会造成两种不利因素：1、储存颗粒物，使得管内颗粒体积浓度减少，实验条件不固定，影响实验结果；2、固液两相以一定的速度流经此间隙，由于突然的高度差，流态发生紊乱，造成固液两相流不稳定，影响管路阻力测量等。所以，传统的连接方式是不能满足要求的。At present, flanges, bolts and gaskets are often used for steel pipe connections. The flanges are welded to the steel pipes, and gaskets are added between the flanges on both sides to realize the connection of steel pipes. This connection method causes a gap between the steel pipes. When using a closed steel pipe to study particle transport experiments, this gap will cause two unfavorable factors: 1. The storage of particles reduces the particle volume concentration in the tube, and the experimental conditions are not fixed. Affect the experimental results; 2. The solid-liquid two-phase flows through the gap at a certain speed. Due to the sudden height difference, the flow state is disordered, causing the solid-liquid two-phase flow to be unstable and affecting the measurement of pipeline resistance. Therefore, the traditional connection method cannot meet the requirements.
