Abstract
A tubular joint having an outer part formed by a fitting end of a piping element, and defining a first axis, an inner part formed by a spigot end of another piping element, the spigot end received in the fitting end. The fitting end and the spigot end define a fluid internal circulation space. A flange attached on the outer part and axially abutting against a shoulder formed by the inner part. A layer of polymeric material, extending radially between the outer and inner part, having a radially outer and inner surface both surrounding the first axis and bonded respectively to the outer and inner parts. The inner part rotatable with respect to the outer part about the first axis, and the inner part defining a second axis forming a pitch angle with the first axis. The inner part, the outer part, and the flange limit the pitch angle to lower than 5°.
