No Twist on the tubes

Standard RHP 10 part numbers 3 part numbers Reduced parts inventory

Standard RHP No Male Female end fittings Reduced parts inventory

Standard RHP 50.8 mm 70.6 mm Reduced footprint

Standard RHP Allen 2.5 mm Easy of assembly • Ease of maintenance

Vacuum leak measurement 3 <1.10-10 atm.cm /s

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

RHP 1/4” Vacuum tests Leak: 3 <1.10-10 atm.cm /s With protection rings Without protection rings +180°C +550°C +20°C +20°C -100°C -100°C

Helium pressure tests Leak: 3 <1.10-10 atm.cm /s 80 bar 650 bar 20 bar +180°C +180°C +20°C

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

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 • Low cost — > Initial — > Replacement • Easily modified • Same parts inventory • Connections — > No Gasket — > No dead volume — > Fewer 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.
