The invention discloses a protective device for a tension-resisting wire pressure welded pipe. The device includes a bearing device and a shunting device; the bearing device comprises a U-shaped pull ring body, an inner sleeve and an outer sleeve, external threads are arranged at the two ends of the U-shaped pull ring body, the inner sleeve is sleeved with the outer sleeve, and the shunting device includes a shunting wire clamp and a shunting wire. According to the protective device for the tension-resisting wire pressure welded pipe, a bearing clamp adopts an inner-and-outer taper sleeve configuration mode, and thus ring-tightening force is increased with the increase of axial pull force. Two screw rods connected in series with the U-shaped pull ring body of a wire tension-resisting pressure welded pipe steel anchor ring pass through earring holes in the two sides of the device to bear wire tension, the device is kept in a moderate tension state all the time, and impact force does not generated even if wire dropping occurs in the wire tension-resisting wire pressure welded pipe.
