FAQS
The lifespan of a welding gas cylinder is not defined by time, but by its structural integrity. Cylinders are subject to regular hydrostatic testing (typically every 5-10 years depending on regulations) to ensure they can withstand the required pressure. As long as a cylinder passes these tests, it can remain in service for decades. However, damage, corrosion, or significant wear can necessitate retirement, regardless of test results. Proper handling and maintenance are critical for maximizing a cylinder’s lifespan.
Welding gas cylinders should be visually inspected before each use. This inspection should include checking for obvious signs of damage, such as dents, corrosion, gouges, or valve damage. The cylinder should also be checked to ensure the label is legible and the gas type is correctly identified.
