Cym Materiales SA manufactures shot blasting machines for pipes steel industry ensuring high productivity with a low operating cost and a process that does not pollute the environment.

TUB machines are designed for surface profiling and removing rust and mill scale from welded steel pipes and can process pipes from 12 mm to more than 1524 mm.

Thanks to its innovative design, the different models of TUB equipment allow optimum use of shot blasting by impacting 100% of the abrasive on the tube, achieving shot blasting above 20 m2 / minute.

They have between one (1) and two (2) turbinesmotor driven from 10 HP to 100 HP according to the needs of each customer.

The machines are provided with accumulative cabinets, loading and unloading pipe systems, rotary system and transfer and rotary movement system.

Features Construction
