Process piping systems play a critical role in a wide range of applications and industries, including petroleum refineries, chemical, pharmaceutical, food, textile, paper, semiconductor, and cryogenic processing plants.

To meet the varying needs of these industries, Marshall Industrial Technologies tailors piping systems to each client’s specific requirements, and can assist in all aspects of design, fabrication, and installation.

Process Piping Materials

A range of materials can be used for process piping, including stainless steel, Hastelloy®, Monel®, and Inconel® alloys. Depending on the substances being transported, certain types of materials may need to be used to optimize the safety and efficacy of the system.

Stainless Steel

Stainless steel is used in sanitary process piping systems for manufacturing facilities , specifically chemicals, pharmaceuticals, food and beverages, and dairy. Stainless steel ensures a stringent standard of cleanliness, it does not rust, and can be installed using manual TIG welding techniques or a combination of orbital and TIG welding.The most commonly used variety is 316L, an iron alloy.

 

Hastelloy® Vs. Stainless Steel

Hastelloy® is a nickel alloy typically used in corrosive and high-temperature environments. Common Hastelloy® applications include those in chemical processing industries, as well as geothermal, solar energy, oil and gas, and pharmaceutical processes. Hastelloy® is highly resistant to uniform attack, localized corrosion, and stress corrosion cracking, and offers ease of welding and fabrication. C276 and C-22 varieties are often used in highly corrosive environments in which stainless steel would not suffice.

 

Monel® Vs. Stainless Steel

Monel® is a nickel-based alloy containing about 30% copper. Common varieties include Monel® 400, Monel® 405, and Monel® K-500. Monel® K-500 includes small amounts of aluminum and titanium, which strengthen the material and make it suitable for aerospace applications. Due to its high corrosion resistance to acids and alkalis, high mechanical strength, and easy shapability and formability, Monel® is often used in highly corrosive environments that require higher thermal conductivity than stainless steel.

 

Inconel® Vs. Stainless Steel

Inconel® alloys, or superalloys, are nickel-based alloys that contain chromium. These are utilized in extreme-condition applications, such as chemical processing, as well as the nuclear, petrochemical, aerospace, and marine industries. Inconel® fabrication offers better performance than stainless steel in extreme-heat conditions and those involving very heavy loads and high stress.

 

Monel® Vs. Inconel®

While both alloys are nickel-based, Inconel® contains chromium, while Monel® contains copper. Both metals are extremely resistant to heat and corrosion, but serve specific industries. Inconel® is often used in gas and oil extraction, while Monel® is typically applied in crude petroleum stills, chemical processing equipment, gasoline and fresh water tanks, and saltwater applications.
