Stainless steel pipes are used in transferring of liquids in high temperature applications. The properties of stainless steel pipes are resistance to corrosion, high ductility, formability and low maintenance. Stainless steel pipes are typically classified or distinguished based on their end use function, environmental conditions, types and grades.
Uses of stainless steel pipe include chemical plants, aviation, marine equipment, food and beverage, oil and gas, pharmaceutical, mining and architectural industries.
One of the most preferred stainless steel grades for tubing and piping applications is Grade 304 stainless steel. Grade 304 stainless steel has high chemical and corrosion resistance, but is not compatible with applications where temperatures fall in the range of 800 – 1640 degrees Fahrenheit (F) because of its proneness to carbide precipitation. Conversely, Grade 304L stainless steel pipe does not have this issue because of its lower carbon content limit, thus making it suitable for welding and higher temperature applications. Other types of stainless steel often possess additives, such as nickel or molybdenum, which strengthen properties that are desirable in particular applications.
