When ordering please furnish a sketch showing the location of the safety plug and tapped connecting holes.

These tanks should be selected when a larger gas volume or smaller tank size is required. The arrangement of service ports and tapped holes shown is only an example.

External tanks are required a) when the manifold plate volume is not sufficient to limit the pressure increase to 10%, or b) when pad-mounted cylinders are used. Threaded tanks are quickly produced at a competitive price, and they provide maximum operational safety.

The connection fittings and the control unit can only be assembled on the face of the end cap. For each 5 liters of gas volume one 1/2" - 20 BS 150 safety plug must be used. If the control console is mounted to the tank, its internal safety plug can be counted as one plug.

Drilled diameters larger than 126 mm should be capped with a plate and "O" rings. The number, grade, and preload of the screws must be specified for a pressure of 165 bars (the maximum pressure of the safety plugs), a safety factor of 1.5, and a cyclic fatigue loading.
