The working principle of the steel pipe outer wall shot blasting machine

The shot blasting machine for the outer wall of the steel pipe is a kind of equipment specially used for cleaning the outer wall of the steel pipe, removing the oxide, rust and improving the surface roughness. It is usually used in steel pipe manufacturing, petrochemical, pipeline construction and other fields, for the treatment of various types of steel pipe surface cleaning and treatment.

The working principle is as follows:

Feed system: The steel pipe is fed into the feed system of the shot blasting machine through the conveying equipment. A roller table or conveyor belt is usually used to ensure that the steel pipe can smoothly enter the shot blasting machine.

Shot blast cleaning chamber: After entering the cleaning chamber, the steel pipe is positioned and begins to rotate along its own axis. The cleaning room has a high-speed rotating shot blast and spray gun.

Shot blasting cleaning process: start the shot blasting device and project the shot blasting particles onto the outer wall surface of the steel pipe. Shot blasting particles have a certain impact force and can remove the oxide, rust and other dirt on the surface of the steel pipe. At the same time, the spray gun will release cleaning agents (such as water or solvents) to help clean the outer surface of the steel pipe.

Shot blast particle recovery and reuse: During the cleaning process, shot blast particles bounce off the surface of the steel pipe after contact and are recovered by the recovery system. After screening and cleaning, the recovered shot blasting particles can be used again to realize the recycling of shot blasting particles.

Discharge system: The cleaned steel pipe leaves the shot blasting machine from the shot blasting chamber through the discharge system, usually through the roller table or conveyor belt.

In general, the steel pipe wall blasting machine uses high-speed rotating shot blasting particles and spray guns to impact clean the steel pipe wall, and at the same time, through the recovery and reuse of shot blasting particles, to achieve continuous and efficient cleaning operations. This can provide a clean and suitable surface for the outer wall of the steel pipe, which meets the requirements of subsequent coating, galvanized and other surface treatment.
