But in some situations the method of a correction factor is not accurate, because the heat loss changed by different type of couplings, the method of simulation is not accurate yet because they ignore the axial heat conduction when the temperature of coupling is higher than the outer face of the pipe, and the methods by conducing experimental device is too complicated, which demand precision instruments and long test time.
In the literature, the temperature of coupling is simulated by CFD software, and then the heat loss is calculated by the convection heat transfer model in steady and radiation heat transfer model，and the heat loss is 475.21W.
