FIELD: oil-and-gas industry.
SUBSTANCE: flow string protectoliser comprises first and second circular sectors. Sectors are connected by split joint and cylindrical joint at oil-well tubing. Power cable extends via through groove. Cutout located at outer surface of the first circular sector is intended for setting of pressure plate by for example bolts. Second circular sector gas extra groove for laying either extra cable or inhibitor feed tube. Damping assy is composed of recess at circular sector outer surface. Rod with bent ends for attachment in said rib is arranged in said recess. Free space of said recess if filled with resilient material. Note here that long element surface part extends above first circular sector outer surface or that of second surface. This allows protection of flow string against mechanical effects.
EFFECT: decreased effects of vibrations at flow string.
