The arrangement addresses the challenge of identifying which leaks are economically significant and verifying the effectiveness of subsequent repairs, a common deficiency in traditional leak survey approaches. By segmenting the main using isolating valves and monitoring pressure decay during periods of minimal air demand, individual segment leak rates are determined. This allows for targeted repair efforts based on calculated financial impact and provides a clear mechanism to confirm successful leak remediation.","language":"en","published_at":"2026-09-15T12:01:13.703495Z","canonical_url":"https://opentechnical.org/p/OT-2026-000000062","status":"PUBLIC","supersedes":null,"keywords":["compressed air","leak detection","ring main","pressure decay","segmentation","utility management","maintenance","energy efficiency"],"extent":{"words":2102,"paragraphs":13,"figures":2},"hashes":{"canonical_text_sha256":"767c0b7e7e09489c70385bfe736a2f8ed7e15bf6f34334c0d82d5d3608fdc1a8","html_sha256":"c332f01ffb9e083dc913ed0fc4db4614f7b1b712cfd7eb3198f4ba4ece028df1","pdf_sha256":"917db1ced6f565f669120bef399685f6598e31bfc7c42804ace7a74972c9dd56","markdown_sha256":"abfdc3d9a759fcfec8ebbdc4a7c011bc58b9721d035621c3fec5e4ee2d0fe834","manifest_sha256":"d1fb8c3747bf6e03bceec4d00d059f8fff8cdc632bf65205b6bc445785a1ff1f"},"links":{"html":"https://opentechnical.org/p/OT-2026-000000062","text":"https://opentechnical.org/p/OT-2026-000000062/publication.txt","markdown":"https://opentechnical.org/p/OT-2026-000000062/publication.md","pdf":"https://opentechnical.org/p/OT-2026-000000062/publication.pdf","manifest":"https://opentechnical.org/p/OT-2026-000000062/manifest.json","signature":"https://opentechnical.org/p/OT-2026-000000062/manifest.sig","integrity":"https://opentechnical.org/p/OT-2026-000000062/integrity"},"categories":[{"category_id":"CAT-000000323","path":"industrial-components-safety-infrastructure/plant-utilities/compressed-air-systems","name":"Compressed Air Systems","primary":true},{"category_id":"CAT-000000297","path":"industrial-components-safety-infrastructure","name":"Industrial Components, Safety & Infrastructure","primary":false},{"category_id":"CAT-000000322","path":"industrial-components-safety-infrastructure/plant-utilities","name":"Plant Utilities","primary":false},{"category_id":"CAT-000000231","path":"industrial-motion-power-transmission/fluid-power/compressed-air-treatment","name":"Compressed Air Treatment","primary":false}]}
