螺旋风管的安装显著地减少了管与管之间的连接点，使管件结合部的泄漏减少到最低程度，典型的螺旋风管长度是3~6m，而典型的矩形风管的长度只有1~1.5m；且连接两个螺旋风管只需一个管接件，而传统的矩形风管的连接则常常需要一个完全独立的双法兰系统。螺旋圆风管的配件（管件和接头）的生产已高度自动化、系统化，并具有工业化的质量控制。
The installation of spiral ducts significantly reduces the connection points between the ducts and the pipes, and minimizes the leakage of the joint parts. The typical length of spiral ducts is 3-6m, while the typical length of rectangular ducts is only 1-1.5m. The connection between two spiral ducts requires only one pipe connection, while the traditional connection of rectangular ducts is often used. A completely independent double flange system is required. The production of fittings (fittings and joints) of spiral circular air duct has been highly automated and systematic, and has industrialized quality control.
