NAR Hardware Subcommittee NH-2005.2 Hinged & Bolted MW Covers Actions Push for torquing gauges through different subs. – NOT Established Further Discussion/Investigation/Research Recommend or order utilization of milder gasket mat\'ls Recommend the utilization of 8 jolt manway covers Reduce the utilization or wipe out the utilization of great pivoted and blasted manway covers

Slide 6

NAR Hardware Subcommittee NH-2005.2 Hinged & Bolted MW Covers Elimination of H & B manway covers Query shippers on requirement for advantageous utilization of the manway spread. Recurrence of opening Splash stacking versus shut circle Venting purposes Tank passage, Cleaning, and Visual Inspection access Suggested appropriation of ACC & API individuals for review. IS THERE A NEED FOR H&B MANWAY??

NAR Hardware Subcommittee NH-2005.3 Shear Plane Arrangement Actions Use of gaskets that consider focusing and better sealability (e.g. pinwheel gaskets) with latches and game plans that suit shearing of the valve to spout association Closed in April \'06

Slide 8

NAR Hardware Subcommittee NH-2005.4.1 Eliminate VRVs Actions Decision to permit auto makers and proprietors keep on requiring Vacuum Relief Valves as standard on non-weight autos. Shipper can ask for their disposal based upon information and control of the operation of the autos. Shut in April \'06

NAR Hardware Subcommittee NH-2005.4.2 VRV Design Concerns NAR Trend 2001 - 2005 * Estimated

Slide 10

NAR Hardware Subcommittee NH-2005.4.2 VRV Design Concerns MANY Potential Recommendations. Give outline that is less inclined to spill in a move over condition Enhanced Seal Design – Quad Seal Rings versus O-Rings Review Test Protocol for New Valves (Reseating Capabilities) Use of Corrosion Resistant Seats/Valves (e.g. Stainless Steel) Providing the Stem Profile Below the Body Casting Tying the Cap to the Valve Body and not the Stem Investigate whether higher Vacuum Rating Pressures may help the seating and reseating qualities of the valve

Slide 11

NAR Hardware Subcommittee NH-2005.4.2 VRV Design Concerns WHERE TO FOCUS? No advancement on suggestions VRV NAR is not high contrasted with different NARs on NON-Pressure autos Still warrants subcommittee to push ahead on proposals, however WHICH ONE

NAR Hardware Subcommittee NH-2005.5 Threaded Connections Rich Phelps

Slide 14

NAR Hardware Subcommittee NH-2006.1.1 PRDs Springs on AA Cars Proposal: Mandate the utilization of a Corrosion Resistant Spring on an AA PRD (was composed as Aluminized) Background: SCC issues on carbon steel springs in AA administration DOCKET T90.13 ALREADY EXIST Research and Data: Stainless steel (or different amalgams) springs Other security (coatings, and so on.) Increased investigation interims Enhanced review systems Lower O 2 levels in tank (N 2 cushions) Lower stress levels in springs

Slide 15

NAR Hardware Subcommittee NH-2006.1.1 PRDs Springs on AA Cars AAR/BOE database – the utilization of aluminized, SST (or other compound) springs, defensive coatings can not be questioned. Likewise examination interims, improved review, Oxygen level in autos can not be questioned. Low Activity from this subgroup

Slide 16

NAR Hardware Subcommittee NH-2006.1.2 PRDs (Valves) O-Rings Discussion: Issues with O-Rings in administration on PRDs (Valves) Research and Data: Where is the issue? Decay Misalignment Missing Incompatible Incorrect Size Low Temperature abilities of regular elastomers

Slide 17

NAR Hardware Subcommittee NH-2006.1.2 PRDs (Valves) O-Rings

Slide 18

NAR Hardware Subcommittee NH-2006.1.2 PRDs (Valves) O-Rings AAR/BOE Database – O-ring material can not be questioned. Can not close, unless shippers/proprietors give the data. What causes decay? Need to research Qualification Dates (time of O-ring) – Need to examine. Low Temperature abilities of basic elastomers DuPont (Chief Engineer) advisor added to group
