Robust piping system

One of the expansion joints accidentally failed while being cleared with a steam supply. Investigators determined the sponsors of this modification did not address the fact that sometimes process lines were blown clear with 150 psig ( 1,040 kPa gauge) steam. The robust piping system was compromised by an expansion joint that could not withstand I lie heat. Fortunately, there were no injuries. 

In order to facilitate the above requirements in a cost-effective manner, one should resort to a more robust piping system, such as the sandwich pipe technology, since the incorporation of the traditionally used single-wall steel pipes can no longer be considered feasible for such applications. 

Piping systems should be designed to minimize the use of components that are likely to leak or fail. Sight glasses and flexible connectors such as hoses and bellows should be eliminated wherever possible. Where these devices must be used, they must be specified in detail so they are structurally robust, compatible with process fluids, and installed to minimize the risk of external damage or impact. 

PYROCLOCK A modular system of vented delays with a range of burn times which form robust fuses. May be used for connecting to piped match or similar for the timed firing of shells etc.
