In the Steel Pipe Cleaning Shot Blasting Machine or pipe descaling equipment, the pipe is kept on the inward side of the Screw conveyor unit. The pipes are transferred into the work chamber of pipe blasting equipment. The work chamber houses 2 Nos. of bottom-mounted blast wheel station which fires abrasive media from the bottom side of the rotating pipe. The pipes accurately shot blast cleaned while they are passing through the blast stream area. The pipes come out from the outlet portion of the pipe descaling equipment and are removed manually. The conveyor velocity is varying in pipe descaling equipment. The steel pipe shot blasting machine is provided with one opening inlet and one outlet vestibule. According to the size of the pipe blasting machine sufficient no. of rubber, the curtain is provided to trap avoiding abrasive shots. The entire pipe blasting equipment is ventilated with the help of a powerful Pulse Jet type continuously operated Dust Collector.
Pipe Cleaning Shot Blasting Machine procedure :
The two types of pipe blasting procedure. We provide both Internal Pipe Blasting (Cleaning) and External Pipe Blasting (Cleaning). In an internal pipe blasting procedure, the internal pipe cleaning tool is connected with Air Operated Portable Shot Blasting Machine. The internal pipe blasting method is automatic and manual. The blasting nozzle of the internal pipe cleaning machine is rotating by air. While in External Pipe blasting procedure it can be done by airless shot blasting machine and Air Operated shot blasting machine.

Operating Principle of Pipe Shot Blasting Machine:
In a pipe blasting machine having two blast wheels, these blast wheels are positioned at the bottom and top side of the pipe blasting machine. The entire cabinet is filled with Manganese Steel Tile. The inlet and outlet side cabinet (pipe blasting equipment) is provided through the suction rubber curtain of different sizes matching different OD of the pipe. Rubber curtain prevents escaping of shots from pipe blasting equipment. The entire pipe shot blasting machine is properly ventilated by a powerful Pulse jet type Dust Collector. The pipes are kept on the inner side of the screw conveyor unit and are taken into a blast chamber where a blast wheel abrasive media to clean the surface of the pipe and is thus thoroughly blast cleaned in portable sand blasting machine. This cleaned blasted pipe comes out from the outlet portion of the conveyor belt from where the pipe is taken out from pipe blasting equipment to a suitable place.
