Proven Success

Vacuum leak measurement < atm.cm /s 3

No leak detected on any sample Vacuum and 200 bar pressure test at 300°C

With protection rings RHP 1/4” Vacuum tests Leak: < atm.cm /s 3 Without protection rings -100°C +20°C +180°C -100°C +20°C +550°C

20 bar Leak: < atm.cm /s °C Helium pressure tests 80 bar +180°C 650 bar +20°C

RHP 1/4” No detected leak 1,900 bar Oil high pressure tests RHP 3/8” 1,600 bar (burst pipe)

At 1,600 bar pipe bursts

Why IGS Systems ? Reduced connections. Fewer welds. Reduced Footprint. Lower Cost. Process improvement Less dead volume. ??????

Integrated Gas System High cost More Connections Welding still required Many different sealing systems Completely new parts inventory

The Facts 8 Component IGS Stick has 18 gasketed connections 36 seal planes. Welds are still required. Reduced Footprint. Yes BUT $$$ Cost may be 3-4 X present. Blocks & Gaskets = dead volume Process improvement. ???

RHP Modular —> Initial —> Replacement —> No Gasket —> No dead volume —> Fewer Connections Low cost Easily modified Same parts inventory Connections Weld free

The Facts RHP Has 8 gasket free connections. No welds required. Reduced Footprint. Yes. Cost same as present. No Blocks No Gaskets No dead volume = Process improvement.
