Design of a Gas Supply System

The design of a gas supply system depends on the one hand on the maximum discharge quantity of an acetylene cylinder, type 40,48,50 (5001 per hour in normal single-shift operation), on the other hand on the weekly average consumption and also on cost-effective logistics. 

Gas supply systems can comprise of single-cylinder units, gas cylinder manifold units, cylinder bundle units (6 or 16 cylinders) and mobile acetylene supply plants, e.g. containers, acetylene trailers with 8 or 16 bimdles (16 cylinders per bundle) that can provide up to 2304 kg of acetylene with one vehicle. 

An acetylene supply plant consists of a high-pressure, medium-pressure and possibly a low-pressure section. In addition to the pressure regulators, safety devices such as manual safety cylinder or bundle connectors, non-retum valves, automatic quick acting shut-off devices, flame arrestors and multifunctional safety devices have to be installed. 

ISO 15 615 have to be complied with. The initial approval of acetylene plants has to be carried out by qualified persons and/ora notified body. Recurrent inspections are also required. 

Before planning or modifying such plants it is advisable to contact a gas supplier who employs specialized application engineers and qualified staff.
