23.01.2022 Todays write up is to understand Gas cylinders marks. The technical name for stampings on a gas cylinder is called a design code. Every high-pressure cylinder that is registered has a design code, this helps a gas cylinder test stations and cylinder users understand what the cylinder has been engineered for. ... Photo (this is a general example) 1. The first mark relates to the cylinder thread type. 2. The second mark is the manufactures mark. 3. The third mark is the cylinders serial number, this is the cylinders unique serial number. 4. The fourth mark is the cylinders tare weight, this is the weight without gas or a valve, this helps to reference if there has been any metal loss from the cylinder. 5. The fifth mark is the water capacity of the cylinder, how much water it holds, this mark helps a test station to work out the volumetric expansion test during a hydro if the cylinder has stretched too much. 6. The six marks pw ph is the cylinder working pressure and the cylinder hydro pressure. 7. The seventh mark is the standard the cylinder as engineered to. 8. The eight mark is the mark of the test station mark. 9. The ninth is the mark when the cylinder was made and pressure tested. So hopefully this has helped some to understand what the design code means.

17.01.2022 De Valving A Cylinder Cylinder de-valving is possibly one of the most dangerous tasks involved with a cylinder. If you need to de-valve a cylinder here are some steps to follow. ... TAKE NOTE: SERIOUS INJURY OR DEATH COULD RESULT FROM DE-VALVING CYLINDERS. ALWAYS TAKE YOUR CYLINDER TO A LICENCED TEST STATION. 1. Understand the gas traffic within the cylinder, is it toxic?, Is it flammable, what pressures could I be dealing with. Please take note some gas traffics are very lite in weight, all because the cylinder might feel empty/lite, it might contain pressure. 2. Open the valve slowly, If gases start escaping close valve and seek expert advise. 3. If no gases are released get high-pressure air (air compressure) apply air pressure via blow gun to the valve in open position, if air enters the cylinder and is released when air blow gun is removed, this proves the valve is not obstructed and is operational. The cylinder is empty. If no air enters the cylinders or escapes when air blow gun is removed, the valve could be collapsed, seek expert advise. 4. If you are satisfied that the cylinder is purged and is safe, then clamp the cylinder, SLOWLY de-valve the cylinder. If the valve is tight and hard to remove. STOP! seek expert advice. If the valve rotates freely then it's safe to say there is no pressure pushing up against the valve and is presumed safe to de-valve. TAKE NOTE: DE-VALVING A PRESSURISED CYLINDER COULD RESULT IN DEATH. NEVER TRY THIS AT HOME. ALWAYS SEEK EXPERT ADVICE.

15.01.2022 Importing a Gas Cylinder from Overseas. This is an issue we see quite common within the test station. For a gas cylinder to be refilled legally within Australia that gas cylinder needs to comply with the Gas Cylinder Test Scheme, the scheme is enforced in all states and territories within the Commonwealth of Australia. ... Every high-pressure cylinder able to be refilled needs to be registered and also bear the Test station mark and last month and year when it was tested by a station within Australia. When you import a gas cylinder that can be refilled. If the gas cylinder has not been registered and has been certified by a gas cylinder retest station within Australia, legally it can not be refilled. This is in compliance with AS2030 & AS2337. If you do want to import a gas cylinder and choose to have it registered and tested, by all means, you may. It is a costly exercise. It might be prudent to purchase one already within Australia that is compliant. If you choose to purchase a gas cylinder from an importer within Australia, enquire that the gas cylinder has been registered and it bears a gas cylinder test station mark and the month and year it was tested. Being ignorant in this matter may cause you to face a prosecution with Safework if someone was using the gas cylinder and was injured whilst decanting or refilling the gas cylinder.

01.01.2022 A common question we get regarding retest dates, how do we know when the test is due. This is based on the date of cylinder being manufactured, or the last test date or if the two can not be determined then by default you test the cylinder to create a base line to work with. Now all licenced test station have a mark so it can clearly be identified globally which station tested the cylinder.... Beside the test mark is the month then year when the cylinder was tested. With in Australia the mark looks like a cylinder with numbers inside it. As you can see below with one of the cylinders we test, our test station no is 720. How do you know the frequency in Australia it is based on AS2030. Here is a link to our site explain the retest dates http://www.firesys.com.au/Periodic-Inspection-Testing-Dates
