A centralizer for tubular elements is provided which includes an inner part formed by a first material having high mechanical performance and chemical stability and an outer part arranged on said inner part, formed by a second material. The second material may be an autolubricating material. The second material may further possess a low coefficient of friction. The second material may additionally possess lower mechanical performance and chemical stability than the first material. A method of manufacturing the centralizer is also provided, including steps of injecting the first material on a tubular element to form the inner part on the tubular element and injecting the second material to form the outer part on the formed inner part.

Centralizer for tubular elements

A protector for the ends () of tubular elements (), which comprises: A tubular element () which comprises the threadless protector is also disclosed.

An assembly for storing elongated members, the assembly comprising an elongated support element and a pair of segments. The segments are disposed on opposite sides of the elongated support element from each other, and each of the segments defines a cradle for supporting an elongated member. The pair of segments is joined together at a seam formed by locally heating and melting contacting edges of the segments to fuse them together. Moreover, the pair of segments is fixed to the elongated support element against movement in a longitudinal direction of the elongated support element. The elongated support element has a textured region of raised protrusions, indentations, or holes, over at least a portion of the surface thereof. Each cradle comprises a center portion located longitudinally between a pair of inclined portions. When an elongated member is supported in the cradle, the center portion of the cradle is convex about an axis parallel to the longitudinal axis of the elongated support element, such that water will drain laterally off of the cradle.
