I have seen copper tubing on the aftercoolers of large air compressors fracture from excessive vibration. Brass pipe fittings can also fail if they have porosity or are overtightened. It would be ...

I'd assume the reasons the dates vary is because the tanks are swapped out at regular intervals, tested, and then stored until needed. The cylinders were installed since the last D check, so I assume it's every few years.

... message news:48b87a64$1_9@news.peopletelecom.com.au... Did you also note that the cylinders are filled to a pressure of 1850psi and minimum 2.87 mm (0.113 inch) wall thickness. And you guessed that your LPG bottle does not have that pressure either. Gas cylinders (CIG) have something like 2500psi are a much thicker wall and tested on a regular basis. ...

Everyone seems to have a story, but it always seems to happen to a friend-of-a-friend. First, I'm distinuishing between tank {body} failures and valve failures. In the industrial world, 95+%% of the valve failures occur when someone ...

Surely an organization with QANTAS much vaunted "safety culture" would have a record of when and where these bottles, some of them near 18 years old - and some older - were tested in accordance with CAR - ...
