摘要

The utility model relates to the field of oil and gas production, in particular to devices for protecting threaded joints of oil and gas field pipes during their transportation and storage. The fuse contains a housing having a U-shaped profile, and a steel shell mounted on it, a removable cover, inner and outer sealing elements made in the form of rings of elastic material. The inner sealing element is located on the inner surface of the housing at the point of contact with the end surface of the nipple element. The outer sealing element has a L-shaped profile, the base of which, in contact with the nipple element, is made conical and with U-shaped cutouts. A tightness of the nipple element of threaded connections with a fuse is achieved when exposed to adverse environmental factors. 2 s.p. f-ly, 1 ill.
