The manufacturing of chemicals and petrochemicals and the production of oil and gas are extremely corrosive for the equipment that comes into contact with these materials. This can rapidly lead to repair and/or replacement of equipment causing expensive and highly disruptive downtime. Also known as Towers in some regions, a Hastelloy Column from TITAN Metal Fabricators can help minimize or avoid this break in production with its strong corrosive resistance.

Specification of Hastelloy as the material of construction in severe industrial manufacturing environments for Columns offers a long-term and highly cost effective method of damage avoidance.

Careful analysis of the fluids and processes have led to Hastelloy Columns being widely used in the process industries, and have been shown to be highly corrosion-resistant in these extremely harsh environments.

Life Cycle Benefits of Hastelloy Columns

Hastelloy Columns are highly cost-effective over the entire life cycle of the equipment.  Properly maintained, they can operate for decades, making them a very economical choice over other available metals.

Hastelloy Columns can:

  • Deliver many years of economical service life
  • Eliminate expensive downtime due to equipment failure
  • Provide outstanding corrosion resistance
  • Provide excellent stress cracking resistance

Hastelloy the Metal

For its myriad applications, the processing industries are constantly in pursuit of highly reliable materials. Hastelloy’s beneficial performance has led to wide acceptance and growth of its use in the areas of energy, health and environmental, oil and gas, and pharmaceutical.

Hastelloy Columns are widely specified by plant operations management and maintenance specialists who appreciate their toughness and ability to withstand very aggressive fluids.

The attributes of the Hastelloy alloys include high resistance to uniform attack, outstanding localized corrosion resistance, excellent stress cracking resistance, and ease of welding and fabrication.

Please see Applications of Hastelloy for a more in depth look at additional uses for Hastelloy that include some comparative corrosion resistance data, media, concentrations and temperatures.

Hastelloy Corrosion Resistance

Hastelloy Columns perform well in the harsh fluids inherent to manufacturing of chemicals, petrochemicals, and in the oil & gas. These chemicals are frequently at very high temperature, testing the material’s strength and corrosion resistance, yet a Hastelloy Column is extremely effective and efficient.

To view a list of process materials where Hastelloy is commonly used, please visit Applications of Hastelloy.

*Note: Final selection of material must be based on actual evaluation of the metal in the corrosive medium.

For a general guide on corrosion resistance, temperatures and concentrations please see TITAN’s publication, “Corrosion Resistance of Metals in Various Chemical Media” for additional information.*
