Grit Blast and Condition O.D. Machine Necks with I.D. and O.D. Threads Machine Necks with I.D. and O.D. Threads Grit Blast and Condition I.D. Grit Blast and Condition I.D. Vacuum, Steam Clean & Dry I.D. Vacuum, Steam Clean & Dry I.D. Install End Plugs Install End Plugs Solvent Wash and Paint Solvent Wash and Paint Purge with Dry Nitrogen Purge with Dry Nitrogen Assemble Assemble

10 Quality and Inspection Process All Pipe is Ultrasonic Tested All Pipe is Ultrasonic Tested Properties are Tested from Test Ring Properties are Tested from Test Ring Yield Tensile Elongation Charpy V Notch Yield Tensile Elongation Charpy V Notch Brinell Hardness Tests Brinell Hardness Tests O.D. is Magnetic Particle Inspected O.D. is Magnetic Particle Inspected Machined Threads are Dye Penetrant Tested Machined Threads are Dye Penetrant Tested Hydrostatic Test Hydrostatic Test Final Ultrasonic Inspection Final Ultrasonic Inspection Assemblies are Air Tested Assemblies are Air Tested Inspections and Testing Witnessed by Independent Agencies Inspections and Testing Witnessed by Independent Agencies

11 Specifications Design specification is contingent on what gas is used and how it is used. Design specification is contingent on what gas is used and how it is used. Hydrogen - Ground Hydrogen - Ground ASME UPV Code Section VIII Div 1 Newest Version Current Addenda and Appendix 22 Material - ASME SA 372 Grade J Class 70 Hydrogen - Transported DOT - 3AAX (Pressure) Hydrogen - Transported DOT - 3AAX (Pressure) Material - AISI 4130X

12 Concerns Hydrogen is Difficult to Store Efficiently Hydrogen is Difficult to Store Efficiently Requires Higher Pressures than Other Gases Requires Higher Pressures than Other Gases Higher Pressure Results in Smaller O.D.s and Thicker Walls Higher Pressure Results in Smaller O.D.s and Thicker Walls More Difficult to Attain Required Properties More Difficult to Attain Required Properties

13 Solutions CPI working with ASME and Compressed Gas Association CPI working with ASME and Compressed Gas Association Working Committees have Been Formed to Address Hydrogen Storage Working Committees have Been Formed to Address Hydrogen Storage Research Laboratories such as Sandia National Laboratories are Testing Materials Research Laboratories such as Sandia National Laboratories are Testing Materials
