Specification Feedback

The intent of this section is to inform all users that a spec feedback mechanism is in place, and is located on the MLCA Naval Engineering Division’s website. Spec feedback is a very important part of our overall continuous improvement process, and is crucial to specification development. It will allow spec writers to capture all specification-related lessons learned, and avoid mistakes or ambiguities in follow-on availabilities. All feedback will be reviewed, evaluated, and responded to in a timely manner.

If you have access to the CGWeb (Intranet), please use the following link, which will connect you to the MLCA(v) Naval Engineering website, for submitting your feedbacks:

http://webapps.mlca.uscg.mil/vdiv/specifications/feedback/default.cfm

If you do not have access to the CGWeb (Intranet), you may still submit your feedbacks, using the following web link:

3.6.2.1 Tank.

· Tank name/number (as applicable).

· Hydrostatic test pressure.

· Date of inspection and test.

· Testing facility.

3.6.2.2 Relief valve.

· Valve number.

· Lifting pressure.

· Date of test and set.

· Name of testing facility.

4. QUALITY ASSURANCE

4.1 Hydrostatic test.

Coast Guard Drawing 175 WLM 551-001, Rev H, Compressed Air System Diagram American Society of Mechanical Engineers (ASME), PTC 25, 2001, Pressure Relief Devices

3. REQUIREMENTS

3.1 General. The Contractor shall inspect and test each designated (see paragraph 1.1) air receiver and their associated relief valves. Assume one relief valve per receiver unit unless otherwise indicated. Refer to Coast Guard Drawing 175 WLM 551-001 for guidance.

3.2 Air receivers. The Contractor shall do the following for each designated air receiver:

3.2.1 System blowdown. Blowdown the air receivers and collect the blowdown (condensate) into a separate container for inspection.

3.2.2 Inspection and testing. Accomplish the following and submit a CFR.

3.2.2.1 Visual inspection. Visually inspect the blowdown (condensate) under a bright white light for oil or particulate contamination. Clean and visually inspect the internal and external surfaces of the air receiver for signs of corrosion, pitting, and other damage.

3.2.2.2 Hydrostatic testing. Isolate the air receivers by disconnecting all piping, relief valves, and pressure switches. Install pipe plugs/caps to prevent system contamination and in accordance with manufacturer’s testing procedures. Hydrostatically test each compressed air receiver in accordance with manufacturer’s recommended procedures to 1½-times the nominal operating system pressure. Hold for five minutes. There shall be no visible permanent deformation. After testing, drain and thoroughly dry the air receivers with warm air. Dispose of testing water in accordance with all applicable Federal, state, and local regulations. Submit a CFR including test pressure and results.

WARNING!

Do not drain any fluids, including fresh water, into any space, bilge, or exterior location.

Handle nitrogen bottles with extreme caution. They can be easily fractured internally.

3.3 Relief valves.

3.3.1 Option for valve renewal. The Contractor may opt to renew any/all relief valves in lieu of inspection and testing, at no additional cost to the Government if preferable for the Contractor. Ensure all new valves are commercial-standard type valves.

3.3.2 Inspect and test. The Contractor shall do the following for each designated air receiver associated relief valve the Contractor does not elect to renew; and submit a CFR:

3.3.2.1 Visual inspection. Disassemble as required, and visually inspect all parts for defects and deterioration.

3.3.2.2 Lifting pressure test. Perform a lifting test on each air receiver relief valve in accordance with manufacturer’s recommendations and ASME PTC 25. Ensure that each valve seats cleanly after pressure relief (without simmering), and with no allowable leakage.

3.3.3 Adjust and install. The Contractor shall adjust the relief pressure on the designated air receiver relief valves as necessary to obtain the specified lifting pressure. After adjustment, perform a final check to confirm each relief valve's lifting pressure with the COR present. After successful confirmation, install the relief valves. Renew all O-rings and gaskets.

3.4 Data plates. The Contractor shall affix an anodized aluminum test data plate with epoxy resin cement to each air receiver and relief valve body. The data plate shall be engraved with ¼-inch high letters, stating the following:

3.4.1 Air receivers.

· Receiver name/number(as applicable).

· Hydrostatic test pressure.

· Date of inspection and test.

· Testing facility.

3.4.2 Relief valves.

· Valve number.

· Lifting pressure.

· Date of test and set.

· Name of testing facility.

4. QUALITY ASSURANCE

No additional requirements.
