The invention relates to a method of forming a resin coating layer on the PE and the curved bend fittings, Would who presented a method of forming a PE resin coating layer on the surface of a conventional curved pipe and a curved pipe fitting is welded process of rotation into the preheated material in the PE resin powder folk which the rotary motion of the material, rather than the dotted line movement to the crank movement because it is a powder coating state is not constant and uneven development was the problem of reducing the life blossomed. The present invention invention a base thereof to the invention in order to solve the above problems when slowly rotating in which the clamping in rotation the material obtained in the pre-treatment and pre-heating process the first and second process jangchigi state spraying PE resin powder from the upper part thereof, a spraying When the PE resin powder is deposited in a third step and here to be welded to the surface of the material (1) at a constant thickness of this time, the process of the deposited coating layer to the powder resin passage spreaders while spraying stops are retracted, cooled by spraying instead of the cooling water because it coupled to the fifth step of the cake desorbed with a one-touch type at step 4 and this jangchigi (4) rotating the products to be uniformly electrodeposited in wanjeong can contribute greatly to the quality and workability improvement.
