Corrosion and Seized valves
Corrosion and Seized valves

Not protecting the threads between cylinder threads and the valve threads can cause Galvanic Corrosion. This corrosion can seize a valve on a cylinder. It is important to protect the threads from corrosion. Read further to find why it happens.

Requalification of cylinders VHT-UE-MAE

There are three main types of cylinder requalification. Hydrostatic requalifications, Ultrasonic Examination and Modal Accoustic Emissions. They all check for differnet issues; ability to expand, detection of corrosion and specific damage to a cylinder. They all have different issues and great benefits.

Most industries rely on the hydrostatic requalification process to ensure cylinder safety. However, this scheduled process may not be enough to ensure the safety of high pressure cylinders. Some industries have designed their own Visual Inspection Program (VIP) which they recommend between the requalifications. The SCUBA retail industry has developed an annual cylinder VIP. They wanted a system beyond the government regulations to keep their participants safe due to the environments in which they subject their cylinders.
