Hydrostatic pressure testing cylinders
Medical oxygen cylinders are required to undergo hydrostatic pressure testing every five years. The purpose of the test is to evaluate the strength and leak resistance of the cylinders. During the hydrostatic pressure test, the cylinders are filled with water and pressurized to examine their pressure capabilities. The pressure tightness can be assessed by shutting off the supply valve and observing for pressure loss. Our testing station in Woerden is equipped to perform hydrostatic pressure testing on various types and sizes of cylinders.

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.
