<p>A bending, restrictor assembly (10) for rise with a pipeline section (12) has a sleeve (14) affixed to the pipeline section, an outer collar (20) slidably positioned relative to and over the sleeve, and an inner collar (24) slidably positioned relative to an interior of the outer collar. The inner collar (24) is in spaced. longitudinal relation to an end of the sleeve. The inner and outer collars are slidable relative to a bending of the pipeline section. A series of holes and keyways (36, 38) are formed in the inner and outer collars. Pins (46, 48) are inserted into corresponding holes and keyways so as to correspond to a limit, of the bending radius of the pipeline section (12 ).</p> |
