摘要

At present during construction and operational commissioning of main oil and gas lines pipes with external factory polyethylene coating are used. Comparing to field coating of pipelines with insulation material introduction of factory insulation of pipes technology allowed for both getting a boost of pipes construction and significantly improve efficiency of its anticorrosive protection. In both, the first and the second, cases for backing up and laying pipes with external factory insulation coating the chains and cords cannot be used. Extreme pressure in the contact area leads to damage of insulation coating, inducing metal corrosion where sections with damaged insulation contact with water and soil. Woven power grips are used for laying pipes with factory insulation coating. These grips are manufactured of multilayer technical fabrics. Structure of multilayer technical fabrics and conditions of its formation on a loom determine effectiveness of the woven power grips manufacturing process. In this work the improvement of multilayer technical fabric was conducted and experimental researches of its formation on the loom were carried out. The influence was determined of warp yarn input tension, value of different tension of shed and value of spade on value of beat-up force, main technological parameter determining intensity of fabric formation process. The researches that were carried out allowed to improve the structure of the multilayer technical fabric. Comparative analysis of conditions of prototype formation and formation of proposed multilayer technical fabric on the loom was earned out. Resulting from the experiment beat-up force value regression dependences on value of input tension of warp yarns, different tension of shed and value of spade were obtained. Analysis of regression dependences allowed to determine optimal parameters of loom threading.
