We, Divine Metal & Alloys A typical application of the Stainless steel 304 pipe would be its use in heat exchanger. A heat exchanger is a system that causes transference of heat between two or more fluids, Since the SS 304 welded pipe is an economically viable option, they are more often used in heat exchangers. While heat exchangers require moderate resistance to corrosion and good tensile strength as primary properties, the very versatile SS 304 efw pipe is able to cater to their needs without causing a dent in the buyer’s pocket. Moreover, the Stainless Steel 304 erw pipe performs the functions rather effectively.
