<p>The present invention relates to a pipe coupler with a pipe protective cap and, more specifically, to a pipe coupler with a pipe protective cap preventing the separation of a coating layer from the front surface of the front end of a pipe perpendicular to a fluid flowing direction due to the pressure of a fluid continuously applied to the pipe by including the pipe protective cap covering the front end of the pipe inserted into a coupler body. The pipe coupler with the pipe protective cap according to the present invention connecting the hollow pipe where the coating layer is formed on the outer surface while the pipe is watertight or airtight includes the coupler body including a longitudinal cavity wherein the pipe is inserted into the front side of the cavity and connected to the pipe; a pipe fixating member formed inside the cavity of the coupler body and fixating the pipe inserted into the coupler body; and a packing member which is made of an elastic material, is formed inside the coupler body, and seals a gap between the coupler body and the pipe, wherein the pipe is inserted. The present invention is characterized by additionally including the pipe protective cap formed inside the cavity of the coupler body including a through-hole on the center to flow the fluid, a circular lateral wall to cover a part of or the whole outer surface of the front end of the pipe inserted into the coupler body, and a locking protrusion protruding inward from the lateral wall.</p> |
