In general, for the convenience of operation, here may also adopt the method of pressure vessel of anticorrosive spiral steel pipe. The spiral pipe manufacturer adds a margin factor (except flange bolt) on the basis of the corresponding working temperature. Table 5-2 Under normal circumstances, the design temperature of piping components is determined. Working temperature Tw (℃) Design temperature T (℃) -20 <T
