Hydrostatic pressure testing cylinders
Cylinders filled with medical Oxygen have to be hydrostatic pressure tested every five years. The cylinders have to be tested for strength and leaks. The hydrostatic pressure test involves filling the cylinders with water and pressurization of the cylinders in order to test the pressure. The pressure tightness can be tested by shutting off the supply valve and observing whether there is a pressure loss. We can hydrostatic pressure test various types and sizes of cylinders at our testing station in Woerden.

Yes, we can arrange transport for the cylinders from our warehouse in Spijkenisse to our warehouse in Woerden.
The date of the hydrostatic pressure test should be engraved in the shoulder of the cylinder. If you cannot find any engravement on the cylinder, the cylinder needs to be hydrostatic pressure tested before it can be filled. If you do not understand the engravement on your cylinder, you can send a picture to our staff.
It takes one day to hydrostatic pressure test cylinders. Cylinders of 40L and larger can only be hydrostatic pressure tested on Tuesday.
Cylinders have to be hydrostatic pressure tested every 5 years.
We can refurbish cylinders. See our page regarding refurbishing cylinders.
If you are uncertain whether your cylinders are in sufficient condition for refilling, you can send pictures to our staff for evaluation.
Medical Oxygen has a limited shelf life of 3 years and therefore should be refilled before it expires.
