Product Description

 Steel pipe inner wall shot peening machine is a novel cleaning equipment that is used for processing any kind of steel pipe inner walls of different sizes. The steel pipe inner wall shot peening machine has powerful processing capability and different shot blasting or sand blasting processing devices can be selected according to different diameters of steel pipes. The hydraulic motor drive is adopted by shot blasting and the pneumatic motor drive is adopted by shot peening.
The steel pipe inner wall shot peening machine is composed of front and back sealed chamber controllled by pneumatic  turning, spray gun and gun control device , gun- carrying car, variable frequency speed regulation walking system, steel pipe rotating system, steel pipe tightening system, automatic loading and unloading system,  shot recovery system by wind force, sand hopper, sandblasting tank, winnowing separator, dedusting system, pneumatic system, compressed air system and electric control system.
The steel pipe inner wall shot peening machine can automatically load or unload steel pipe,can blast grit automatally to the inner surface of steel pipe.First, open the door of reveral sealed chamber.The automatic loading mechanism can automatically put the steel tube from the storage rack into the working position. The tightening device will hold the steel pipe when it is into the exact position.When the sealed chamber is reversed, the steel pipe will start rotating, gun- carrying car will drag the gun and the inner wall of steel pipe will be sprayed.  Our dedusting system with large air volume can recycle the shots and collect the dust in the steel pipe by wind force.When the cleaning is finished,the valves of shot supplying  and blasting will be closed. The shot peening system will be out of the pipe cleaned up. The sealed chamber will move outward.The loading system will automatically pull steel tube out. The steel pipe will roll into the discharge platform automatically.This is one operating cycle.

An inner wall shot peening machine is adopted by the small-bore steel pipes. The pipeline inner wall shot peening machine is a dedicated device that is used for cleaning metal pipeline inner walls and is the extension and development of the compression feeding type shot peening cleaner. The steel pipe inner wall shot blasting machine/shot peening machine is the critical equipment for the painting of the interior of the pipelines and can enable the treatment effect of the inner wall surface of the pipeline to reach level Sa2.5 to level Sa3 and can greatly prolong the service life of the pipeline. The steel pipe inner wall shot peening processing line mainly comprises a movable trolley, a sand hopper, a shot blasting tank, spray guns, spray gun carrier, a steel pipe carrying system, a bottom abrasive belt conveyor, a bucket elevator, a service platform, a separator, a dust collecting system, holders, a pneumatic system, a compressed air system and an electric control system.
The steel pipe inner wall shot blasting machine/shot peening machine is provided with a pneumatic loading and unloading system on the conveying trolley and can realize automatic loading and unloading on both sides. After the workpieces are put on the working position, the mobile sealing chamber which is driven by the reducer moves towards the fixed sealing chamber in order to seal both sides of the steel pipe.
During cleaning, an wind power conveying system is adopted by the abrasive recycling system. The abrasive recycling can be realized through the dust collecting system and the negative pressure effect of the interior of the steel pipe. When the abrasives get to the sealing sub-chamber, because the space of the sub-chamber is instantaneously increased and the air conveying force immediately disappears, the abrasives fall off on the abrasive recycling belt conveyor.
