Can your 200 psig propane tank remain in operation?
Propane tanks with a maximum allowable operating pressure (MAWP) of 200 psig (1380 kPa) need to meet certain requirements to remain in operation. These include, but are not limited to:
- The tank must have been inspected by a qualified individual and deemed safe within five years immediately before November 1, 2017.
- The tank must be fitted with a pressure relief valve with a maximum set pressure of 250 psig and a minimum relieving capacity according to the National Fire Protection Association – 58 – Liquefied Petroleum Gas Code (NFPA-58).
For tanks manufactured according to paragraph U60 or U69 of the 1949 (or earlier) edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII Division 1:
- The tank is permitted to remain in operation only at its present location and shall not be moved and operated elsewhere.
For tanks manufactured according to paragraph U200 or U201 of the 1949 (or earlier) edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code Section VIII Division 1:
- The tank shall be re-rated according to NB-23 National Board Inspection Code to increase the MAWP from 200 to 250 psig. Re-rating documents including revised calculations, inspection records, and other required documents shall be submitted to BCSA for registration before November 1, 2017.
Compliance with these requirements is needed on or before November 1, 2017. Non-compliance will lead to the removal of these tanks from operation on or before May 1, 2018.
