产品介绍：刚性管道可以使用旋转接头以获取柔性自由度。特别是管道上不宜使用软管的场合。加装旋转接头的管道不会减弱任何一点密闭输运流体的能力， 实际上更可以获得各平面360度旋转的优势。

Product introduction: Rigid pipes can use rotary joints to obtain flexible degrees of freedom. Especially when it is not suitable to use a hose on the pipeline. Pipes with rotary丿oints will not reduce the ability to transport fluids in a closed manner at any point. In fact. they can obtain the advantage of 360-degree rotation of each plane
