Polyurethane Foam Coating Insulation Pipe Making Machine For Hot / Cold Pipline

1. Rust removal of steel pipe/piece, the hydraulic lifting mechanism is used to transport the steel pipe/piece to the transmission pipe conveying line of the steel pipe shot blasting cleaning line, and the steel pipe/piece is turned and entered the shot blasting room. When the internal sensor collects the signal of the steel pipe/piece, the control system commands the shot gate to open, and the pellets are thrown against the outer wall of the steel pipe to remove the rust and impurities attached to the outer wall of the steel pipe. The steel pipe workpiece enters the output roller table, and after shot blasting, the outer surface of the steel pipe workpiece meets the requirements of sa2.5.
2. Polyurethane spraying, the steel pipe travels at a uniform speed on the rotating tugboat with a certain Angle. The spraying robot evenly sprays the polyurethane raw materials on the spiral forward steel pipe in the form of umbrella, mist and uniform mixture, and the polyurethane raw materials are launched within a certain time to achieve the compressive strength and design thickness required by the technical requirements and complete the production of the spraying insulation layer. Multiple spraying can be performed when the required thickness is large
