A boiler is an energy conversion mechanical device: through boiler combustion, the chemical energy in the input fuel is converted into high-temperature flue gas, and then the thermal energy contained in it is converted into steam, high-temperature water, or organic heat carriers using working fluids such as water, to drive downstream machinery to do work, or directly exchange and utilize thermal energy. Huaxu specializes in producing stainless steel heat exchanger tubes made of high-temperature resistant materials. Through high-precision cold rolling and cold drawing technology, the heat exchanger tubes have good dimensional tolerances, excellent internal and external surface quality, and good material properties. They can be cold bent and hot bent into U-shaped tubes, coil processing, etc. according to customer requirements for heat exchanger tubes.
