HIGH-PRESSURE CYLINDER TESTING
Southern Gas Services became IANZ accredited as a hydrostatic cylinder testing laboratory in 2013 due to the large number of industrial gas cylinders it currently has in circulation. We primarily became certified to service our own fleet of cylinders however, due to increasing demand we also offer testing and filling for customer ownership cylinders. Our capabilities include the inspection and testing of aluminium and steel high pressure cylinders from 3L to 80L water capacity and pressures up to 8000 psig (540 barg). New Zealand laws require that all gas cylinders are regularly inspected and tested to ensure that they are safe and fit for the storage of high pressure gases. Beverage and some welding gases require a periodic test cycle of 5 years while most other gas cylinders, argon etc, require a testing cycle of 10 years. Cylinders that are older than 40 years of age require a periodic test every 5 years regardless of the gas contained within it. The cylinder test mark can be located on the shoulder of the cylinder which is stamped and highlighted by silver paint.
We have state of the art hydraulically driven valving machines, testing rigs and drying racks for fast efficient testing.
WHAT WE CAN OFFER:
– Cylinder collections and delivery of your tested and filled cylinder.
– UV inspection to identify any hydrocarbon contamination.
– Hydrocarbon decontamination using a non-toxic specialised cleaning solution.
– Internal surface cleaning by rumbling with specialised media.
– Safe and legal scrapping of cylinders or valves that do not pass their hydrostatic test.
NOTE: Cylinders MUST be customer owned for us to fill or test and SGSL require proof of purchase. They CAN NOT be part of another companies rental fleet OR part of a “swap” system. Our approved fillers & cylinder inspectors must first approve the cylinder as an ownership before we can test or fill it.
Our periodic testers are strictly trained to comply with all of the requirements set out by IANZ, New Zealand’s regulatory authority, CTLA and Worksafe. Our Laboratory and staff all under go mandatory auditing every 2 years to ensure compliance.
