Abstract: PURPOSE: To shorten drying time of a corrosion preventing oil by employing an alkyd resin type corrosion preventing oil and alsy by deriving a temperature for steel pipe preheating process and an atmospheric temperature for after-heating process from a certain equation.  
     CONSTITUTION: A time t required for drying a coating of the corrosion preventing oil can be expressed by an equation of t=tf+tc(tf: a required holding time from completion of coating process to after-heating process; Tc: a required cooling time). And a required holding time tf for this after-heating process can be expressed by (or derived from) by an equation of log eft ≥28.5X -0.5   1  + 38.6X -0.05   2  - 32.3 (X 1 : a steel pipe preheating temperature; X 2 : an after-heating atmospheric temperature). The required cooling time tc is for cooling a steel pipe, which got extremely hot at preheating and drying processes, down to 50 - 60°C or less in order to solidify the corrosion preventing oil having thermal plasticity. From the above equations, values for tf and tc can be sought, and therefore, a value for a time t required for drying of a coating of the corrosion preventing oil is to become able to be sought.
