Abstract: A swivel assembly including a swivel bolt and housing is disclosed. The swivel bolt may include a first portion, a second portion, and a body portion connecting the first portion and second portion. The second portion may include a transverse channel. The housing may be configured to receive at least a portion of the second portion of the bolt and the housing may include an annular channel operatively aligned with the transverse channel of the swivel bolt. A swivel bolt may be formed as a single piece and/or may be formed using additive manufacturing technology. In embodiments, a swivel bolt may include a fluid passage having a bend with shaped or contoured inner and outer surfaces.

Abstract: A fireproof cover for fluid conveyance products includes an inner layer including a first polymer, an intermediate layer including a thermally insulating material, and an outer layer including a second polymer. One or more additional intermediate layers may be disposed at least partially between the inner layer and the outer layer. The intermediate layer may include fiberglass and may be disposed around the inner layer. The one or more additional intermediate layers may include (i) a first layer of basalt tape wrapped around the intermediate layer, (ii) a layer of fiberglass wrapped around the first layer of basalt tape, and (iii) a second layer of basalt tape wrapped around the layer of fiberglass.
