PE ASTM A790 Stainless Duplex Steel Pipe Seamless 6000MM
Duplex Steel Pipe:
Duplex stainless steel was developed to combat common corrosion problems encountered with the 300 series stainless steels. “ Duplex ” describes a family of stainless steels that are neither fully austenitic, like 304 stainless, nor purely ferritic, like 430 stainless. The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy ( stress corrosion cracking resistance and high strength ) with those of an austenitic alloy ( ease of fabrication and corrosion resistance ).

A heat exchanger is a specialized device that assists in the transfer of heat from one fluid to the other. In some cases, a solid wall may separate the fluids and prevent them from mixing. In other designs, the fluids may be in direct contact with each other. In the most efficient heat exchangers, t......
