What we can offer

Our company is currently the leading manufacturer of automated steel pipe shot blasting machines, steel pipe inner and outer wall shot blasting machines, steel pipe inner and outer wall shot blasting machines, and steel pipe inner and outer wall shot blasting machines in China. We are a professional manufacturer of steel pipe inner and outer surface cleaning equipment.

Process flow of steel pipe inner wall shot blasting cleaning machine:
Pneumatic feeding → Automatic pipeline bracket lifting and moving → Automatic pipeline bracket in place and lowering → Steel pipe rotating bracket moves towards the rear sealing chamber → Front sealing chamber moves → Steel pipe self rotation opening → Dust removal opening → Lifting opening → Spiral opening → Shot blasting trolley moves → Sandblasting starts (from front to back) → Sandblasting ends → Backward blowing → Belt conveyor stops → Lifting stop → Dust removal stop → Self rotation stop → Front sealing chamber moves → Self rotating bracket moves → Lifting device rises and moves → Lifting device moves into place and lowers, unloading → Powder spraying, oil coating, and powder treatment.

Scope of application of steel pipe inner wall shot blasting cleaning machine:
The anti-corrosion steel pipe inner wall sandblasting machine and QGN series steel pipe inner wall sandblasting machine are a combination cleaning machine for cleaning the inner wall of steel pipes. They clean the outer surface of oil pipes through sandblasting and the inner surface through sandblasting to remove all surface oxide scales.

The steel pipe outer wall shot blasting cleaning machine uses a roller mechanism to start sequential operation of the shot blasting machine when the workpiece enters the main shot blasting chamber. After shot blasting treatment, most of the oxide scale, dirt, and other attachments on the surface of the workpiece are cleaned up, and the surface of the workpiece can reach Sa2-2.5 level. The working mode of the assembly line is continuous circulation.

The shot blasting particles of the steel pipe outer wall shot blasting cleaning machine shot blasting system are collected and processed by the circulation processing system, and continue to be used by the shot blasting machine and shot blasting system. The working mode of the circulation system is as follows: scattered pellets are transported to the bucket elevator through the lower longitudinal screw conveyor, lower belt conveyor mechanism, and horizontal screw conveyor. The bucket elevator lifts the pellets and debris to the upper part of the cleaning room, and the high-efficiency BE separator is transported by the horizontal screw conveyor. After being processed by the BE separator, dust and debris are separated from the good pellets. The good pellets are stored in the storage hopper for use in the shot blasting machine and sandblasting system. In order to handle the large amount of dust generated during polishing and shot blasting rust removal, the machine is equipped with one set of high-efficiency new LT-48 pulse blowback cleaning filter cartridge dust collectors. This dust collector has high dust removal efficiency and is easy to install and maintain. The purified air meets the following emission standards.
