Information × Registration Number 0219U100116, 0115U006701 , R & D reports Title Research and implementation of means of raise physicomechanical and corrosion characteristics of welded joints of pipes and other products for the main pipelines maintained in mountain and seismodangerous conditions. popup.stage_title Head Rybаkov Anаtolii O., Кандидат технічних наук Registration Date 24-01-2019 Organization E.O.Paton Elektric Welding Institute National Academy of scinces of Ukraine popup.description2 Presents the results of the investigation of new processes of welding of longitudinal welds of large diameter pipes for main gas pipelines designed for operation in difficult mountainous and seismically hazardous environments. It is shown that the process of combined, gas-flux, multi-pass welding in СО2 (intermediate joints) and under flux (facing joints) is the most effective for such conditions. In the case of the using of recommended welding materials, high impact strength of welded joints is provided at a temperature of minus 40оС. The developed technology was tested during welding of control welded joints and pipes. Product Description popup.authors popup.nrat_date 2020-04-02 Close
