Hastelloy C27 is an alloy made of nickel-molybdenum-chromium and is a corrosion-resistant alloy. It offers excellent resistance to various corrosive environments, including reducing and oxidizing media. In this post, we will explore the various Hastelloy C276 tubing uses across multiple industries.
Chemical Processing Industry
The chemical processing industry is one of the industrial sectors where Hastelloy C270 tubes are used extensively. The tubes are often used in applications that involve strong acids like hydrochloric acid, sulfuric acid, chlorine, and phosphoric acid, as the alloy can withstand the highly corrosive nature of these acids. The Hastelloy C276 tubing use also includes the components in distillation columns, chemical reactors, and scrubber and heat exchangers. Due to its corrosion resistance to water, it is also used in offshore oil and gas production.
Oil and Gas Industry
Hastelloy C270 has applications in the oil and gas industry, especially in harsh environments and where corrosive fluids are commonly used. The tubes are often used in oil refineries, offshore platforms, and petrochemical plants. This alloy exhibits exceptional resistance to chloride-induced stress corrosion cracking and pitting. Thus, it is well suited for applications that involve chloride-rich environments like brine, sour gas, and seawater.
Power Generation
Hastelloy C27 tubes also play a vital role in the power generation industry, where resistance to high temperatures and aggressive environments is important. They are particularly used in coal-fired power plants as Hastelloy C27 is able to withstand high temperatures and corrosive environments of a power plant. Therefore, it is also used in power generation equipment like steam generators and nuclear reactors.
They are commonly used in boilers, heat exchangers and condensers. Their resistance to oxidation and carburization at elevated temperatures allows them to withstand the demanding conditions encountered in power plants that also include corrosive gasses and high-pressure steam.
Pharmaceutical Industry
The pharmaceutical industry requires stringent cleanliness and purity of products. Hence, Hastelloy C27 tubes are preferred in this industry due to their exceptional resistance to corrosion and contamination. They are used in applications like pipework systems, storage tanks, and pharmaceutical reactors. Moreover, their opposition to a wide range of chemicals and sanitizing agents makes them suitable for maintaining a high level of cleanliness and product integrity standards in the pharmaceutical manufacturing process.
Waste Treatment and Pollution Control
Hastelloy C27 tubes also play a critical role in waste treatment and pollution control systems. They are used in flue gas desulfurization or FGD systems as they provide excellent corrosion resistance against the highly acidic gasses produced by industrial combustion and help reduce sulfur dioxide emissions from power plants.
Hastelloy C27 alloy is resistant to corrosion from the sulfur-containing compounds formed during the scrubbing process. They are also used in various applications in wastewater treatment plants, incineration facilities, and chemical scrubbers. They help to mitigate environmental pollution and maintain operational efficiency.
Food Processing
Due to its corrosion resistance and non-toxic nature, Hastelloy C27 is used in the food processing industry for making food processing equipment like sterilizers, pasteurizer pipes, storage tanks, and valves.
Final Take
The wide range of qualities of Hastelloy tubes makes them suitable for various industrial applications and for making industrial equipment, especially those used in highly corrosive environments. It is a versatile alloy with excellent corrosion resistance and high strength.
