Information × Registration Number 0218U000517, 0116U006121 , R & D reports Title The creation of manufacturing technology of heat exchanger modules, which ensure the reliability and safe operation of recovery boilers powerful combined-cycle power plants operating in the secondary metallurgical gases popup.stage_title Head Skulsky Valentin Yurievitsch, Registration Date 31-01-2018 Organization E.O.Paton Electric Welding Institute of the National Acfdtvy of Science of Ukraine popup.description2 Developed and tested new electrodes with basic coating for welding method "top-down" concocting (wall thickness 2.5-3 mm) small diameter pipes (? 32 ... 60 mm) when assembling the tube bundles with a density of 250 seeds/m2 of heat-exchange modules of the recovery boiler. Studies have shown that the additional introduction into the coating of rutile and zircon concentrate and pulp significantly improves welding-technological properties of the electrodes, allows you to perform top-down stitches. Welded joints of thin-walled tubes of small diameter, which are made arc welding electrodes new way "top-down" are of a high technological strength and mechanical properties.5481 Product Description popup.authors Єлагін Валерій Павлович Давидов Євген Олександрович Захаров Леонід Степанович. popup.nrat_date 2020-04-02 Close
