Due to possible conversion of carbon to graphite (graphitization) - carbon steel pipes should be avoided for  temperatures above 425oC. Instead Alloy steel should be used. 1 Pa = 10-6 N/mm2 = 10-5 bar = 0.1020 kp/m2 = 1.02x10-4 m H2O = 9.869x10-6 atm = 1.45x10-4 psi (lbf/in2) (lbf/in2) T(oF) = [T(oC)](9/5) + 32
