Axenics specializes in hydrostatic testing, otherwise known as hydro testing, DOT specifications 4B 260 and 4B 300 low-pressure, stainless-steel chemical canisters.
In order to meet Department of Transportation (DOT) Pipeline and Hazardous Materials Safety Administration (PHMSA)specifications, stainless steel cylinders must be tested every 3, 5 or 10 years by a DOT-approved hydrostatic testing facility. The time frame for requalification testing is dependent upon the age and construction of the cylinder, the gas it contains, and the rating of the cylinder by the original equipment manufacturer (OEM).
DOT- Approved to Test, Repair & Rebuild
Our team of experts is qualified to test, inspect, certify, repair and/or rebuild low-pressure stainless-steel cylinders to meet the strict standards set forth by the DOT PHMSA, and in accordance with CGA (Compressed Gas Association) Methods for Hydrostatic Testing of Compressed Gas Cylinders. We hold the following DOT Stainless Steel Cylinder Approval:
- RIN#: 1550, expires 6/19/2020
- K#: KI33, expires 6/19/2020
- M#: M6329, expires 3/9/2020

Axenics uses a state of the art hydrostatic tester to perform all requalification hydro tests. The stainless steel cylinders are examined for leaks, and the overall integrity of the unit is assessed. Axenics’ hydrostatic tester measures the rate of expansion of the tube under water pressure, and determines whether the unit can safely hold the amount of pressure it is rated for. We also laser etch our certification number on your cylinders for easy identification for the years your tanks are now certified.
