Introduction of Process
1. Remove rust from steel pipe surface
2. Heat the steel pipe to get it ready for polyurethane spraying
3. Spray polyurethane evenly on steel pipe outer surface
4. Wrap melted HDPE strap around the PU foam
5. Trim the pipe ends
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 signal of the steel pipe/piece is collected by the
internal sensor, 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.
Polyurethane spraying, the steel pipe in a certain Angle of the
rotating tugboat uniform speed, spraying robot will be the
polyurethane raw materials in the shape of umbrella, fog and mixed
evenly spray on the spiral forward steel pipe, polyurethane raw
materials launched within a certain period of time, to meet the
technical requirements of the compressive strength and design
thickness, to complete the production of spraying insulation layer.
Multiple spraying can be performed when the required thickness is
large.
