Courses are designed by industry experts with decades of experience. Flexible learning paths accommodate both beginners and advanced learners.

Refurbishment
Quality control and testing in the refurbishment department are even more rigorous, requiring additional procedural steps, heightened monitoring, and extensive inspections. Beyond visual assessments, Sigma Cylinders conducts comprehensive laboratory tests and uses borescope cameras to inspect the cylinder interiors precisely. Adhering to ISO safety standards, every cylinder undergoes thorough de-gassing and cleaning before any repairs begin. Repairs proceed only after meeting these stringent quality controls and inspections, ensuring the highest safety and reliability standards.
