Alloy Equipment – Realizing the Benefit of Proper Selection

Many of our customers whose processes utilize high chloride materials or are subject to extremely corrosive applications know that the life span of a vessel which uses a properly specified  nickel alloy or reactive (commercially pure) metal can justify the additional expense.

While the cost of an alloy tank itself can be higher, remember to factor the additional costs incurred from downtime, maintenance, or replacement, including removal and installation. Over time, these costs can be significantly greater with carbon steel or even stainless steel applications.

We have heard many stories of tanks that were built from carbon steel and coated with a corrosion resistant liner instead of selecting the proper alloy. Those tanks are now costing tens of thousands of dollars in maintenance annually. With the current economic conditions, these costs couldn’t come at a worse time.

Alloy equipment can also be specified in combination with stainless steel to help reduce the overall cost without sacrificing corrosion resistance. For instance, it is quite common to clad stainless steel flanges with alloy sheet or plate on large flanges to reduce the cost of forgings or rolled rings while maintaining the corrosion and structural requirements of the design.

A properly applied material can last for many years with little or no maintenance, even in the harshest applications.
