三通是管道安装中的重要配件,它的几何形状影响着流体的输送、管道的机械强度、现场施工速度以及焊接自动化等问题,国内工程使用的三通是气割马鞍口焊接而成,而国外早已广泛使用无缝三通,并已形成专业化、系列化生产。无缝三通比马鞍三通具有如下优点:其相贯处是圆滑过渡,肩部呈园弧形,有利于流体的输送,把阻力、涡流降低到相当低的程度,而且耐压强度也高,承受管路的三向
Three links is an important part of the pipeline installation, its geometry affects the delivery of fluids, pipe mechanical strength, site construction speed and welding automation issues such as the use of domestic tees are welded gas saddle mouth welding, and foreign Has long been widely used seamless tee, and has formed a professional, serialized production. Seamless tee than the saddle tee has the following advantages: The smooth transition is the intersection, shoulders were park arc, is conducive to the delivery of fluid, the resistance, eddy current down to a very low level, and the compressive strength is also high , To withstand the three-way pipeline
