Shot blasting machines for LPG, CNG and air gas cylinders
GAR, CAB, SAT, CAB-TUN y EST-TUN LINES
Cylinder shot blasting — solutions for every production volume
CYM Materiales offers the complete line of equipment for the automatic shot blasting of LPG, CNG, oxygen, acetylene and industrial gas cylinders, covering small-scale batch production through to high-capacity continuous process plants. The solutions are designed for periodic inspection centers, gas filling plants and cylinder manufacturers requiring efficient, safe surface preparation with minimal manual intervention.
The ECOGNC automatic shot blasting machine is the economical, compact solution for medium production volumes: the cylinder is loaded onto rotating rollers that spin it during blasting, ensuring complete coverage of the exterior surface in cycles of 2 to 8 minutes. For high-volume continuous production, the GAR line processes cylinders in automatic pass-through mode using two centrifugal blast wheels: the GAR-RI model uses angled (non-parallel) rollers that simultaneously advance and rotate the cylinder, while the GAR-RD model uses double-cone (diabolo) rollers for greater rotational stability, reaching up to 800 cylinders per hour in the GAR 600 RD model.
For cylinders that require blasting in the suspended position — including fire extinguishers and industrial gas cylinders — the spinner hanger (CAB) and rotary table (SAT) machines offer batch blasting with 360° coverage of heads and bases. The CAB-TUN continuous pass-through tunnel is the high-productivity solution for cylinders up to 45 kg on an overhead chain conveyor. For large-format cylinders, such as stationary LPG tanks and P150 cylinders, the EST-TUN 15×15 machine processes large-dimension containers integrated with a paint line and overhead conveyor.
Applications
Uses and shot blasting processes
CYM Materiales cylinder blasting lines cover the main surface preparation processes for periodic inspection and manufacturing of LPG, CNG and industrial gas cylinders. Equipment selection depends on production volume, cylinder type, required process format and integration with the paint system.
