Simulation in selecting the heat treatment of oil and gas pipe
Tóm tắt
A method is proposed for determining the actual heat-treatment conditions of oil and gas pipe, with allowance for the heat transfer within the furnace chamber. High tempering of 13XΦA steel pipe of elevated operational reliability (strength group K52) is simulated. The precision in simulating the treatment parameters exceeds that achieved by standard monitoring methods. The actual onset of isothermal holding is determined. Corresponding correction of the tempering conditions permits 18-fold reduction in the rejection rate associated with furnace treatment (that is, in the quantity of pipe sent for repeated heat treatment).
