                     软管是一种柔性中空管，设计用于将流体从一个位置输送到另一位置。软管有时也被称为pipes或更普遍的tubing。

               <p>
                     Ducts are conduits or passages used in heating, ventilation, and air conditioning (HVAC) to deliver and remove air.

                     管道是用于加热，通风和空气调节时，输送和排出空气的管道或通道。

                     Pipe (fluid conveyance)
               </h1>
               <p>
                     A pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.
