Product Description

Product Description

  The ASTM A179 standard is applicable to seamless cold drawn low-carbon steel pipes used in the manufacture of heat exchangers, condensers, and similar heat transfer equipment. These steel pipes have a small wall thickness and are particularly suitable for tubular heat exchangers, condensers, and similar heat transfer equipment.
  ASTM A179 standard steel pipes have good heat transfer performance, certain mechanical strength, and corrosion resistance, and are widely used in equipment such as heat exchangers and condensers in industries such as petroleum, chemical, pharmaceutical, food, light industry, machinery, and instruments
  Heat exchanger is a device that transfers a portion of the heat from a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers are common equipment in many industrial sectors such as chemical, petroleum, power, food, and others, and play an important role in production. Heat exchangers can be used as heaters, coolers, condensers, evaporators, and reboilers in chemical production, and are more widely applied.
  Heat exchange tube is one of the components of a heat exchanger, placed inside the cylinder, used for the exchange of heat between two media. Has high thermal conductivity and good isothermal properties. It is a device that can quickly transfer thermal energy from one point to another.
  The main function of heat exchanger tubes is to achieve heat transfer between two or more fluids at different temperatures, thereby completing processes such as heating, cooling, condensation, and evaporation. The performance of heat exchanger tubes directly affects the heat transfer efficiency, reliability, and service life of the heat exchanger
   Application of heat exchanger tubes in different industries
1. Chemical industry: In chemical production, heat exchanger tubes are used in key processes such as heating reaction materials, cooling products, and recovering waste heat, significantly improving energy utilization efficiency
2. Petroleum industry: In the process of petroleum refining, heat exchanger tubes are used to heat crude oil, separate products and other processes to ensure the smooth progress of the production process
3. Power industry: In equipment such as power plant boilers, heat exchanger tubes heat or cool fluids to meet the needs of power production
4. Food industry: In food processing, heat exchanger tubes are used to heat and cool food ingredients and products, ensuring temperature control during the production process
