Description of the operation of the pipe shot blasting line
Unit "UDP" is designed for shot blasting of pipes supplied horizontally with continuous rotation.
The pipes are fed onto a roller conveyor, which provides the pipes with rotational - translational movement along the line with an adjustable feed pitch and speed.
The roller table drive is adjustable to ensure the optimal pitch and speed of pipe feed along the line.
The outer surface of the pipes before cleaning must correspond to the oxidation state of the surface B according to GOST 9.402 - 80 (or A and B. according to ISO 8501 1988).
The surface of the tubes must be free of nicks, oil and grease contamination. The surface of the pipes must be dry.
Pipes are subjected to abrasive cleaning of the outer surface to a degree of cleaning 2 in accordance with GOST 9.402 - 80 (Sa 2.5 in accordance with ISO 8501 - 1P) and a roughness of 40 . . . 90 µm.
