Regulations regarding the design pressure of pipelines

I saw the following description regarding the design pressure for pipelines: Operating pressure Pw (MPa), Design pressure P (MPa): If Pw ≤ 1.8, then P = Pw + 0.18; otherwise, P = 1.8
What are the requirements for the safety protection of gasification process facilities, as specified in 5.2.238 of the first edition of the \"National Training Manual for Design Approvers of Pressure Pipelines\"? … (4) Safety valves should be installed on the buffer tanks, compressor outlets, and gas storage cylinder banks within the gas station. The installation of safety valves shall comply with the relevant provisions of the \"Regulations on Safety Supervision of Pressure Vessels\". The set pressure P0 of the safety valve shall, in addition to complying with the relevant provisions of the \"Regulations on Safety Supervision of Pressure Vessels,\" also meet the following requirements: 1) When P ≤ 1.8 MPa, P0 = P + 0.18 MPa; 2) When 1.8 MPa < P ≤ 4.0 MPa, P0 = 1.1P; 3) When 4.0 MPa < P ≤ 8.0 MPa, P0 = P + 0.4 MPa; 4) When 8.0 MPa < P ≤ 25.0 MPa, P0 = 1.05P. Note: P—Maximum operating pressure of the equipment.

The values used for the pipeline section are converted from Kgf to MPa. 1) When P≤1.77MPa, P0=P + 0.18MPa; 2) When 1.77MPa<P≤3.92MPa, P0=1.1P; 3) When 3.92MPa<P≤7.85MPa, P0=P + 0.4MPa; 4) When P>7.85MPa, P0=1.05P.
GB50253 also has slight differences.
