| 摘要 | In one aspect, the present invention relates to a friction-pin unit. The friction-pin unit includes a sleeve and a guide cone formed at a first end of the sleeve. A shaft is disposed coaxially within the sleeve and a plurality of friction pins extend radially outward from the shaft. The plurality of friction pins are adapted for interference-fit engagement with an inner surface of the pipe. A ring seal is circumferentially disposed around an inner surface of the sleeve. The ring seal adapted to circumferentially seal an outer surface of the pipe. | ||
