Stainless Steel Versus Copper For Helical Coils

Companies all across the country need helical coils in their operations to heat liquids, cool liquids and transfer them throughout their factories. These liquids may be used in oil and gas, aerospace, food service, automotive and other industries. When a company is seeking these coils or a hot oil vaporizer coil in your operations, you have several choices from manufacturers such as Bend-IT, Inc. Besides deciding on the size of the coil, you also need to select the right type of metal.

Stainless Steel Versus Copper

Two of the main types of metals used for coils are stainless steel and copper. Both are ideal for these applications due to their thermal conductivity. Heat can transfer through these metals at high temperatures and pressures. The metals also allow heat to be transferred out of liquids during the cooling process. Yet which metal is better for your company operations? Take these factors into consideration.

Machinability and Strength

You want to select a metal that has the machinability to be bent into different shapes that won’t compromise the strength of the metal. When metals are bent, deformations can form that can cause serious cracking as this situation can affect the usability and longevity of the pipe. Both stainless steel and copper offer great machinability and strength to handle high pressure liquids passing through the coil.

Corrosion Resistance

Certain liquids will react differently when passing through metals. While stainless steel and copper work well as helical coils due to their corrosion resistance, some liquids can cause these metals to corrode faster, lessening their life span. Understanding how the liquids your company uses will react to stainless steel and copper will allow you to select the one that will work better for your operations.

Price

Sometimes the deciding factor comes down to price. While copper is the normal standard for helical coils because of its heat transfer capabilities and other numerous benefits, it is also pricier. So many companies select more cost-effective metals such as stainless steel that can still offer the same number of benefits as copper.
