300-900mm pneumatic rotary inner wall sandblasting gun

300-900MM pneumatic rotary pipe inner wall sandblaster should be used together with pressure sandblasting machine and air compressor, which is equivalent to the normal use of single-inlet and double-inlet sandblasting guns. 2 guns rotate 360 ​​degrees to achieve the purpose of cleaning the inner wall of the pipeline.

The inner wall sandblaster nozzle is made of pure boron carbide sintered at high temperature. Its hardness is extremely high, second only to diamond, and it is resistant to wear and maximizes the service life of wearing parts. This sandblaster is suitable for sandblasting the inner wall of φ300-900mm pipes.

The main air bag of the 300-900 inner wall sandblaster is imported from Taiwan, using high-pressure air to blow the air motor blades in the air bag, thereby driving the gear rotation to drive the nozzle Y-shaped seat to rotate 360 ​​degrees, and then drive the two The nozzles mounted in front of the Y-shaped seat and distributed at 90° rotate at a uniform speed to achieve a uniform 360-degree sandblasting purpose. At the same time, the inner wall sandblaster moves back and forth linearly at a uniform speed along the length of the pipe, so as to clean the inner wall of all lengths of the pipe. Purpose. The surface quality level after cleaning can reach Sa2.5-Sa3.
The 300-900 inner wall sandblaster is suitable for abrasives: brown corundum, copper ore, quartz sand, cast steel shot, cast steel sand, emery and other abrasives with a particle diameter of less than 2mm.
