BoilerTube Material   The selection of boiler tube material mainly depends on the operating conditions, pressure and temperature requirements of the boiler, as well as the chemical characteristics of the environment. Common boiler tube materials include carbon steel, alloy steel, stainless steel, nickel-based alloys, and ceramic composite tubes.   Carbon steel boiler tubes : Feature good mechanical properties and weldability, suitable for general industrial boilers and pressure vessels.   Alloy steel boiler tubes : Contain alloying elements such as chromium, molybdenum, and nickel, enhancing high-temperature and high-pressure resistance, making them suitable for high-temperature, high-pressure boilers.   Stainless steel boiler tubes : Offer corrosion resistance and high-temperature resistance, commonly used in boilers and heat exchangers in special environments.   Nickel-based alloy boiler tubes : Exhibit excellent resistance to high temperat...

Should cold-rolled or hot-rolled tubes be selected for heat exchangers ?   Cold-rolled tubes are more suitable for heat exchangers. The cold-rolling process offers the following advantages:   1.    Surface Quality and Mechanical Performance: Cold rolling allows metal materials to be processed at room temperature, resulting in improved mechanical properties and surface quality. Cold-rolled tubes have smooth surfaces and high dimensional accuracy, which enhances heat exchange efficiency.   2.    Corrosion Resistance and Pressure Endurance: The cold-rolling process refines the metal's grain structure, improving its strength and toughness. This makes cold-rolled tubes more resistant to corrosion, high temperatures, and pressure, making them ideal for harsh environments.   3.    Manufacturing Precision: Cold-drawn tubes have high manufacturing precision and uniform wall thickness, improving the seal and pressure resistan...
