Case Study:
Pressure Balance Sphere

Pressure Balance Sphere

Pressure Balance Sphere is yet another innovative product which has been developed by iNPIPE PRODUCTS™ for a major gas line operator. The pressure balance sphere is designed to eliminate the time (up to 12 hours in some cases) required to dissipate any ingressed gas collected during service. It also removes the risk of over inflation and faulty valves and seal plugs. Service costs are eliminated as there is no need for a filling medium and therefore filling and emptying of the sphere are not required.
