Most of the pipeline supports are L-shaped, one end of each L-shaped pipeline support is installed on a frame structure or a stringer structure of the airplane, and the other end of each L-shaped pipeline support is connected with a clamp used for fixing the pipeline of the airplane. When the pipeline of the airplane is not laid or in the process of laying the pipeline, the pipeline bracket which is not connected with the clamp hoop is exposed outside the frame structure of the airplane and is very easy to damage, wherein the lower parts of the cargo hold and the rear equipment hold areas are high incidence areas of damage of the pipeline bracket. The common types of damage are buckling of the line support due to the stepping of the crew and paint falling off of the surface of the line support, resulting in extensive rework and, therefore, the need to protect the line support prior to laying the lines of the aircraft.
