Jiaozuo Shijia energy-saving heat exchange equipment Co., Ltd.   

        about
        Jiaozuo City Shijia energy-saving heat exchange equipment Co. Ltd. is a furniture has a military production experience and technology to decades of professional heat exchanger manufacturers, strict production management, strong technical force; "honest man, practical work, quality oriented, credit is the soul" is the fundamental operation of enterprises the. Enterprises to adopt advanced production line of finned tube American WHT company, professional production and processing all types of finned tube heat exchanger components and products.
        base tube and the fin nickel base brazing fin tube welding rate was 100%; can be used for welding carbon steel carbon steel stainless steel sheet, stainless steel pipe, welding parts welding in smooth without residue; segment thermal contact resistance is almost zero, significantly less than the thermal Gao Pinhan finned tube, heat transfer capacity than high frequency welding finned tube high about 20%, equivalent to the whole rolling tube and fin. And according to the requirements of processing into an oval finned tube heat exchanger, the test consisting in the same heat exchange area, the heat transfer of 30% higher than the circular finned tube, the air side resistance less than 50% circular finned tube, can effectively reduce the cost of operation of the wind turbine.
        nickel base brazing pipe is a special equipment and process, nickel alloy sprayed uniformly on the surface of mild steel, the in a protective atmosphere make alloy melt, and the infiltration of carbon steel 0.013 ~ 0.024mm, deposited on the substrate surface is about 0.025mm, the overall formation thickness is about 0.05mm of the nickel alloy layer, its main features:
        (1) infiltrated layer alloy uniform, bright, compact;
        (2) there is a fundamental difference with the coating, coating, not the existence of peeling or shedding may;
        (3) the hardness of the surface is about 4 times of common steel pipe;
        (4) high temperature and low-temperature dew point corrosion;
        (5) resistance to erosion and abrasion, no ash and scaling easy product;
        (6) to work in alkali, salt and other corrosive atmosphere environment medium and long-term;
        (7) the price is far below the stainless steel pipe is generally lower than that of the stainless steel tube about 1/4. According to the characteristics of the relevant, but also can improve the convection heat transfer speed to increase the heat transfer coefficient, so as to further enhance the heat transfer ability or reduce the structure size.
        copper welding finned tube with copper and copper plate as material, with phosphorus brazing powder as solder, winding sheet after protective atmosphere brazing furnace brazing processing, segment reliable welding, no contact resistance, and can be processed in accordance with the requirements of elliptical fin tube, the heat exchanger for test consisting in the same heat exchange area, the heat transfer of 30% higher than the circular finned tube, the air side resistance less than 50% circular finned tube, can effectively reduce the cost of operation of the wind turbine.
        the main products of the company are: nickel base brazing fin tube, copper welding finned tube, stainless steel elliptical fin tube, carbon steel, copper elliptical fin tube elliptical fin tube, copper - Copper embedded type finned tube, steel - Copper embedded type finned tube, L type finned tube, high frequency welding finned tube and steel water gravity heat pipe; fin tube type air heater, cooler, SRZ type, SRL type radiator radiator, radiator, heater, GL type heat pipe air preheater, the heat pipe economizer of boiler economizer, etc., and provide product design and to map processing service for the customer.
