The invention discloses a double-sealing-type socket press-fit
pipe fitting and an assembling method thereof. The double-sealing-type socket press-fit
pipe fitting comprises a
pipe material and a socket press-fit
welding head, the pipe material is inserted from the open end to the
welding end, after
insertion, the part located in the socket press-fit
welding head is an
insertion part, a circle ofsealing tape are connected to the outer wall of the
insertion part in a sleeving mode, one end of the sealing tape is parallel and level to the open end, the other end of the sealing tape is close tothe welding end, the gap between the other end of the sealing tape and the welding end is filled with an anaerobic
adhesive layer, and an annular groove is formed in the position, corresponding to thesealing tape, of an outer pipe body; the
pipe fitting and the socket press-fit welding head are subjected to confining pressure through a hydraulic tool and are connected with each other tightly, andtwo confining pressure positions of confining pressure are separately located on the sealing tape and the anaerobic
adhesive layer. According to the double-sealing-type socket press-fit
pipe fitting,the structure and assembling method of the socket press-fit
pipe fitting are improved, the amount of
adhesive filling is effectively reduced, and the phenomenon of adhesive overflowing is avoided; and meanwhile, the installation cost is greatly saved, the sealing performance can be increased, and the installation quality of pipeline
engineering can be ensured under extreme conditions such as high-and-low temperature area and
high pressure environment.
