COOL-DOWN FLOW RATE LIMITS IMPOSED BY THERMAL STRESSES IN LNG PIPELINES.

Author(s) : NOVAK J. K., EDESKUTY F. J., BARTLIT J. R.

Summary

WARM CRYOGENIC PIPELINES ARE USUALLY COOLED TO OPERATING TEMPERATURE BY A SMALL, STEADY FLOW OF THE LIQUID CRYOGEN. IF THIS FLOW RATE IS TOO HIGH OR TOO LOW, UNDESIRABLE STRESSES WILL BE PRODUCED. THE PRESENT WORK EXTENDS THESE CALCULATIONS TO PIPELINES MADE OF STAINLESS STEEL, ALUMINIUM OR 9% NICKEL STEEL COOLED BY LIQUID METHANE OR A TYPICAL NATURAL GAS. RESULTS INDICATE THAT ALUMINIUM AND 9% NICKEL STEEL COMPONENTS CAN TOLERATE VERY HIGH COOL-DOWN FLOW RATES, BASED ON NOT EXCEEDING THE MATERIAL YIELD STRENGTH.
