Inner steel tube is shaped pipe with an inner surface of the spiral ribs, resulting in laminar flow phenomenon due to its wall with an internal thread bump, can effectively overcome the slow flow pipe in the media, and can inhibit the effect of pipe wall of vapor film , thus greatly improving the heat transfer effect of boiler water wall, so that the wall temperature is more uniform. Electric boilers are widely used. Due to the high requirements in the steel pipe, production has some difficulties, so far the country has a long thread in the boiler seamless steel pipe production capacity of only a handful of manufacturers. Inner steel tube material is generally an SA 210A1, SA a 210C, SA a 213T2, SA 15CrMoG a 213T12 and so on. Siemens has developed on the basis of ordinary steel pipe inside the steel tube of the inner optimization, its helix angle (the angle between the axis of the helix) bigger, higher thread height, to further improve the heat transfer efficiency of steel; materials rebar T12, T23 and other pipes, used in ultra supercritical boiler water wall. Shandong Liaocheng Polygram Pipe Manufacturing Co. The company is the high-pressure alloy pipe, fittings matching supply unit for power, petrochemical, oil, gas, gas turbine boiler service SA-210A1 entire line of seamless steel pipe thread, long engaged in various types of fire Power Plant Piping supporting the work, and to assume imported high-pressure elbow, pipe manufacturing, pipe bending services, reserves, management, processing of an integrated body. Annual sales: Chengdu Iron and Steel Group, Baosteel Group, Tianjin Seamless, Hengyang Steel, Baotou Steel Group, Zhejiang Yong, Japan JFE, Sumitomo of Japan, Germany, Mannesmann and other major steel production of alloy tubes and stainless steel pipe supply and demand long-term and stable cooperative relations, to ensure a smooth and timely supply.
