What is Hydrostatic Testing and why is it important?

DOT Hydrostatic Testing NE Ohio Kent Columbus Toledo Cleveland Cincinnati

Hydrostatic Testing is a nondestructive test procedure used to check cylinders for leaks, structural flaws, durability, and corrosion. It is used to check a cylinder's structural integrity. Testing consists of enclosing a cylinder filled with water inside a test jacket filled with water. Pressure is then applied internally to the cylinder, causing the cylinder to expand. The total and permanent volumetric expansions of the cylinder are determined by measuring the amount of water displaced by the expansion of the cylinder when under pressure and after the pressure has been released. An external and internal visual inspection of the cylinder is also performed.

The Department of Transportation sets forth strict regulations regarding the handling, recharging, and transportation of Hazardous Materials. All cylinders bearing a DOT specification marking must be inspected, retested, and marked in conformance with 49CFR.
