发明名称 WATER PIPE HAVING HIGH STRENGTH CONNECTOR AND MANUFACTURING METHOD THEREOF
摘要 PURPOSE: A drain pipe integrating a pipe and a connecting head with the high intensity and a manufacturing method thereof are provided to obtain the excellent intensity even when reducing a material of a connecting head without adding a separate reinforcing material. CONSTITUTION: A drain pipe integrating a pipe and a connecting head with the high intensity comprises a pipe of a synthetic resin material and a connecting head. The pipe has the identical diameter. The connecting head includes a connecting end unit, an expanding pipe unit, and a flange unit. The expanding pipe unit is extended from the connecting end unit while maintaining the large diameter to accommodate one end of the other pipe in the inside and includes a hollow unit crossing an O-ring groove in the inside. The flange unit is formed in the end of the expanding pipe unit.
