SIC Code 3443-11 Description (6-Digit)

Heat exchangers manufacturing is a specialized industry that involves the production of devices that transfer heat from one fluid to another. These devices are used in a wide range of applications, including power generation, chemical processing, and HVAC systems. Heat exchangers come in many different shapes and sizes, and can be made from a variety of materials, including metals, plastics, and ceramics. The manufacturing process for heat exchangers involves a range of techniques, including welding, brazing, and soldering, as well as machining and forming. Quality control is a critical aspect of heat exchanger manufacturing, as any defects or flaws can compromise the performance of the device and potentially lead to safety hazards.
