Tear Down and Inspection

The D.A.S. repair process begins by tearing down, washing, and inspecting all components.

During this process, our Inspection Department works to identify the cause of the damage. We want to help you prevent future repair costs.

After a thorough inspection, clients receive a quote with an outline of all suggested repairs.

Machining and Welding

Testing and Finishing

D.A.S. can test cylinders up to 10,000 PSI before they leave our facility.

After the cylinder passes the testing process, we prepare the cylinder to be shipped. Each D.A.S. cylinder receives a fresh coat of paint and a D.A.S. label for easy tracking.
