SU1550255A1 - Flexible pipeline - Google Patents

Abstract

The invention relates to mining and can be used primarily in the development of minerals from the water surface, as well as from large depths of the ocean. The goal is to increase the strength of the pipeline (TP) by reducing the stress on its walls. Flexible TP consists of a lengthy rubber-fabric hose 1 and floats 2, which have the shape of a torus, are separated by TP and rigidly fixed on the hose 1. Floats 2 have nipples for the passage of light liquids and gases (air). The waterproof additional flexible hoses 4 are wound around the outer surface of the hose 1 and fixed to the ends of the floats 2 nipples. Fixing the flexible hoses 4 in the desired position is provided by elastic linings 5. Ensuring buoyancy and increasing the hydraulic strength of the hose walls in the working condition of the flexible TP is achieved by air injection or light liquid in floats and flexible hoses under a certain pressure. Based on the operating conditions, the external pressure in the sections may vary, i.e. The external pressure in the floats and flexible hoses will vary depending on the internal pressure of the pulp in the flexible hose 1. 2 Il.

Claims (1)

Claim 35 A flexible pipeline, including sections of the pipeline, insulated from one another by floats having nipples, characterized in that, in order to increase the strength of the pipeline by reducing stress on its walls, each section ^{υ of the} pipeline is equipped with a flexible hose wound around its outer wall, the cavity of which communicated with the nipples of the floats of the corresponding section.
