In a periodic inspection, a gas cylinder undergoes pressure testing and internal and external inspection, its empty weight is determined, and its fittings and markings are checked. The cylinder’s external surface is blast cleaned and painted and the date of the inspection is stamped on the cylinder shoulder.
If the cylinder is owned by the client, the client is responsible for the inspection fee whereas the inspection cost for leased cylinders is covered by Woikoski.
Periodic inspections are statutory inspections of pressure equipment to be performed at set intervals. An approved inspection body must inspect and test refillable pressure vessels at predetermined intervals (Decree of the Ministry of Transport and Communications 171/2009, section 188.8.131.52
