The subject innovation is heated plumbing etc. copper (銅管) to be a structural improvement in the socket (SOCKET) used to be the other, the outer peripheral surface of the socket (1) is only the central portion inner peripheral surface yirumyeonseo locking step (2) is a smooth surface inwardly being dolseol, by inclining the both ends of the inner diameter side edge of the socket (1) the inclined surface (4) is one to be formed.; Which will be the strength of the socket (1) to easily work more quickly is increased reinforcement (補强 增大) compared to a conventional socket do not cause breakage at the time of pipe work receptacle (1), the pipe is heated using a long period of heating the operation pressure and therefore sufficiently bear the stress due to the temperature variation in the number of heating up the service life equipment and Hi oil, Dongguan one inclined surface (4) form a 5, 5 on both ends of the inner diameter side of the socket 1, which is is based on a hameuroseo welding solder flows is not flow to the outside flows only into the solder flows is introduced into the so longer block does not flow by the locking step (2) standing in good that the welding state is not the leakage of water concerned, the welding operation Fig. We'll have an easy effect.
