184.108.40.206 Components shall be designed to withstand operating pressures and other specified loadings. 220.127.116.11 There is a commentary available for this Clause. Except as allowed by Clause 18.104.22.168, the pressure design of components shall be as specified in the applicable component standard or specification. The pressure design of components for which no standard or specification is listed in this Standard shall be
a) as specified in CSA B51 or the ASME Boiler and Pressure Vessel Code, Section VIII; or
b) approved by the company as being suitable for the pressures to which the components are to be subjected, based upon an engineering assessment that includes a review of technical data and historical service records.
22.214.171.124 There is a commentary available for this Clause. Cylindrical portions of fabricated components, such as scraper traps, prover pipes, and strainers, may be designed as specified for straight pipe (see Clauses 4.3.5 to 4.3.11). Δ 126.96.36.199 The pressure rating of steel components other than flanges at temperatures up to 230 °C shall be determined by multiplying the cold working pressure rating by the applicable temperature factor given for steel pipe in Table 4.4. 188.8.131.52 There is a commentary available for this Clause. The pressure rating of flanges shall be in accordance with the ratings provided in the applicable manufacturing standard. For temperatures up to 230 °C, if the applicable manufacturing standard does not specify a flange rating, the maximum permissible flange rating shall be determined by multiplying the cold working pressure rating by the applicable temperature factor given for steel pipe in Table 4.4.
