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...
