Musculoskeletal plummet PRODUCT FOR PROTECTION insulating coatings of pipelines in a protective casing (bcc. M)

摘要

1. The bearing-centering product for protection of the insulating coating of the pipeline in a protective casing (BCC. M) comprising bonded together fit connections metal segments with threaded ties at their ends placed and fixed on the outer surface of the metallic support segments, characterized in that the metal assembly segments form a closed ring having an inner diameter equal to the diameter of the equipped tubing at installation of a bCC. M, and to avoid the destruction of the supports due to the rotation of the pipeline, which occurs when a significant length of the casing (pulling length), BCC. M is equipped with 6 to 12 equally spaced in the circumferential direction of the ring rolling bearings in the form of rings arranged along a generatrix of the pair of rollers made of wear-resistant dielectric material, and on the surface of the support ring arranged in a staggered poryadke.2.
