  "id": "MLC-T-OAG-003709",
  "term": "Surge reliever",
  "field": "Oil and gas",
  "definition": "A device specifically designed to mitigate the effects of pressure surges in pipelines by rapidly opening to discharge excess fluid and then slowly closing. Unlike a standard relief valve, a surge reliever is engineered to handle large volumes of fluid and to reclose in a controlled manner to prevent secondary pressure waves. These are commonly installed on long liquid pipelines to protect against overpressure events.",
