Steam condenser is an important large-sized part of thermal power plant, quality of pipe is one of key factors of replacing condensers. Its reliability directly affects financial interest of power plant. They normally chose copper-nickel alloy, copper pipe and etc in former several years. Due to material strength, corrosion-proof and wearability, it not only affected operating life of equipment, but also waste big metal material greatly, hence power plants denied using of copper pipe, and use stainless steel for instead. After running for a period of time, stainless steel condense pipe has better diathermancy compare to brass pipe, running at full load in vacuum condition coincides with design data, thus shows better transcalent ability under longer running condition comparatively. It adopts normal tube expand technique, which provides convenience and fine quality. Through water quality inspection of condensed water, no leakage and vibration proof scale is found, it prolongs operation longevity and reduces cleaning cycles, and is best choice of setting up new unit or old unit's improvement. Since the first condenser stainless steel pipe was developed, we successively provided over 60 sets of high-effective energy-saving stainless steel pipemakings for Ha Er Bin Steam Turbine Factory, Sichuan Oriental Steam Turbine Factory, Nanjing Steam Turbine Factory and relevant power plant per ASTM A249 production criteria. Company are also willing to produce other stainless steel by using 304, 316L material or per GB/T12771-2008,ASTM A269,ASTM A249production criteria or technical agreement.
