312-11 - Acetylene Tank Hydrotest and Recertification Service

Professional Acetylene Cylinder Requalification

Ensuring the safety and compliance of your welding gas cylinders is not just a regulatory requirement; it is a critical component of workplace safety. The Acetylene Cylinder Retest Service provided by Josef Gas offers a comprehensive solution for customer-owned acetylene tanks that have reached their re-qualification expiry date. Acetylene cylinders are unique in their construction, containing a porous mass and a solvent (usually acetone) to stabilize the volatile gas. Over time, the structural integrity of the steel shell can degrade, and the internal conditions must be verified to prevent catastrophic failures.

Our retesting process adheres strictly to Transport Canada and DOT regulations. Unlike standard high-pressure gas cylinders, acetylene tanks require specialized inspection techniques. The process involves a thorough visual inspection for external corrosion, dents, or arc burns, as well as verification of the valve threads and safety relief devices. Crucially, the inspection assesses the condition of the porous filler material to ensure it hasn't settled or been damaged, which could lead to dangerous pockets of free acetylene. By choosing Josef Gas for your cylinder maintenance, you are guaranteeing that your equipment is handled by trained professionals who understand the specific nuances of dissolved gas storage.

Once a cylinder passes inspection, it is stamped with the new test date, extending its service life and allowing it to be legally refilled and transported. This service is essential for welders and fabrication shops that own their cylinders rather than renting them. Regular testing not only keeps you compliant with the law but also protects your personnel and property from the risks associated with compromised pressure vessels. We handle the logistics and technical testing so you can focus on your fabrication work with peace of mind.
