Steel Pipe Inner wall and outer wall Shot Blasting Machine

Steel Pipe Internal Shot Blasting Machine Introduction:

 

Steel pipe internal surface blasting is becoming an important requirement before coating works.  High performance painting system is applied and required the blasted surface to achieve a minimum cleanliness of SA2.5.  Shown below is a typical system specially designed and constructed on turnkey basis for pipe manufacturers.

 

Blast wheel enters the pipe with the pipe being rotated where a high volume supply of abrasive is fed into it.  Blasting is achieved with controlled movement of the variable blast stream covering the full pipe internal length.  Thrown out abrasive is recycled with a system of blow-off action, captured and returned for recovery through a combination of conveyor belt, screw conveyor, bucket elevator, separator and a holding tank.
