Bridge bend refers to the joint between water pipes, or between water pipes and line pipes, which is common in the joint between hot water pipes and cold water pipes to prevent the ground from rising.

As shown in the figure:

Mainly used in building arc steel structure, tunnel support, roof bending beam, subway engineering, aluminum doors and windows, suspended ceiling, cylindrical internal skeleton, balcony handrail, shower room door, production line track, fitness equipment and other industries.

When the fluid passes through the elbow, it is forced to do similar circular motion due to the constraint of the elbow. The centrifugal force generated by the circular motion of the fluid acts on the inside and outside of the elbow, resulting in a pressure difference between the inside and outside of the elbow sensor. The pressure difference (pressure difference) is related to the density of the fluid, the average flow rate of the fluid and the radius of curvature of the fluid's circular motion. Brief introduction of thick-walled elbow: This kind of pressure difference (that is, pressure difference) is beyond the reach of domestic and general pipe benders.
