In the steel pipes coating processing, direct-touching and un-touching are two methods in testing the steel pipes′ temperature. And presently the direct-touching method is mainly used, which is performed by using a tempilstick to get the surface temperature of steel pipes after mid-frequency heating. The two methods have their advantages and disadvantages respectively. In this paper, a kind of infrared testing method is introduced and compared with the direct-touching method. The impact factors in testing temperature are discussed. The application results show that this kind of un-touching method can give much more true and precise temperature values of the steel pipes.
