説明

As one of the applications of high frequency induction heating to ship outfittig work, a new pipe bending method for reducing the pipe fabrication process by elimating elbow fittings and a new method of wringing the pipe edge have been developed and put in practical use. Concerning the relationalization and improvement of the efficiency of the pipe fabrication process, we have noted the need of changing the existing method of using elbo fittings into that of pipe bending by using a short bending radius 1∼1.5 D (D: pipe diameter). So, we have successfully developed, through many systematical experiments, a new pipe bending process using short bending radius thereby breaking the common sense of pipe bending radius resulting in a fair extension of the range of application of short bending radius. Concurrently we have developed a new manufacturing method of wringing (reducing) the pipe edge thereby securing a substantial saving of the working time in the assembling and welding stages and the improvement in the quality of the wringing part. These new manufacturing methods can be expected to be applied in the field of not only ship construction but also land plant thus allowing to fabricate pipes at a remarkably lower cost. The following is a report on the new manufacturing methods.
