Covered Piping Systems (CPS)

(1) Definition. Covered piping systems (CPS) are piping systems on which condition assessments are to be conducted. As a minimum for electric power generating stations, the CPS also include NPS 4 (DN 100) and larger piping in other systems that have a design temperature greater than 750EF (400EC) or a design pressure greater than 1,025 psi (7.1 MPa). (2) Requirements. A program shall be established to provide for the assessment and documentation of the condition of all CPS. A condition assessment shall be performed at periodic intervals as determined by an engineering evaluation. Covered piping systems (CPS) shall be included in a Condition Assessment Program as defined in ASME B31.1. Documentation shall include a statement as to anyactions necessaryfor continued safe operation. 1/17/25 522 CMR - 61 (Mass. Register #1539, 1/17/2025) 522 CMR: BOARD OF BOILER RULES 17.03: continued (3) Records. All records pertaining to the condition assessment of CPS shall be kept on file at the location of the CPS, and shall be maintained and accessible to the Division and Authorized Inspection Agencies for the life of the piping systems. The condition assessment records shall consist of, but are not limited to: (a) Any procedures required by para. 139; (b) Any condition assessment documentation required by para. 140; (c) Original, as-built, as-modified. or updated piping drawings; (d) Original, as-built, as-modified, or updated pipe support drawings; (e) Results from piping stress or flexibility analysis; (f) Piping system diagrams (flow, piping and instrumentation, and/or process diagrams); (g) Valve and other inline equipment data used in original piping design stress analysis; (h) Additional documentation requirements as identified in paras. 141.2 through 141.5; and (i) Details of specially designed components (refer to para. 104.7.2), including details of the design, design method, dimensions, weight, and materials; details of the manufacture, fabrication, and welding; and details of the component examinations.
