Safety Equipment

We utilize Volumetric as well as modified (proof testing) methods as appropriate for the cylinders tested. We also use the Modified testing method for Low-pressure cylinders <900 psi. We are able to perform external visual inspections for cylinders only requiring that test.

 

Our facility also utilizes NDT or Non-Destructive Testing Technology to help in identifying cylinders made with Aluminum 6061 that has the potential for developing cracks in the tread area of the cylinder.  We currently use Visual Plus equipment to assist us in this process. Normally these cylinders were manufactured prior to 1990 and are Exemption cylinders with 6498,7042 or possibly other exemptions as well as DOT 3AL cylinders with pressures from 1800 psi to 3000 psi. Our technicians are extensively trained to standards prescribed by DOT and strive to provide inspections and testing to ensure the safety of the individuals utilizing the cylinders. We are a licensed DOT approved cylinder re-qualification facility with a current Retester Identification Number assigned by DOT.

 

Some of the equipment we use is normally referred to as the water jacket method. This method allows us to accurately measure the total expansion of the cylinder under test pressure and determine the permanent expansion. All cylinders are inspected for damage according to the Manufactures's specifications and the appropriate CGA (Compressed Gas Association) pamphlets which are incorporated into the CFR (Code of Federal Regulations) by reference. We welcome questions regarding the testing or processes as well as the opportunity to show and explain what we do.  If you would like to schedule a time to view the facility and the process we utilize please contact us with your request.
