[0002] Electric melting saddle type branch pipe fitting is a kind of pipe fitting for the connection and branch of pipeline system. It is mainly composed of main body part and electric melting connection part. The shape of main body part is similar to "saddle", which can be straddled on the main pipeline, used to draw out branch pipeline from the main pipeline, and its material is usually plastic material such as high-density polyethylene (HDPE), which has good corrosion resistance and sealing performance.

[0003] In the prior art, such as the utility model with application number 202022745953.4, a kind of electric melting saddle type pipe fitting is disclosed. In order to solve the problem that the saddle surface freely shrinks away from the mold column surface during cooling, the shrinkage process of the saddle surface is no longer constrained by the mold column surface, resulting in uneven saddle surface, which further causes the saddle base to not fit tightly with the target pipeline surface and has gaps. When the preformed electric heating wire ring is selected, the exposed surface of the electric heating wire ring as the welding surface is smooth and flat without recess defects after secondary injection molding. In contrast, the inner wall surface of the saddle base with a conventional semi-circular ring structure is difficult to obtain a smooth and flat surface under the same process conditions.
