Hastelloy tubes are a type of high-performance alloy tube that is designed to withstand extreme temperatures and corrosive environments. These tubes are commonly used in heat exchangers, which are devices that transfer heat between two fluids without allowing them to mix.
Hastelloy is a type of alloy that contains nickel, chromium, and other metals, and is known for its excellent resistance to corrosion and oxidation. Inconel and Haynes are other types of alloys that are often used in the manufacture of hastelloy tubes, and they offer similar properties to hastelloy.
Hastelloy tubes are used in a variety of industries, including aerospace, gas, and plate manufacturing due to their ability to withstand harsh conditions. The B622 method is one of the most common methods used to manufacture hastelloy tubes. There are several different types of hastelloy tubes available depending on the specific application.
Types of Hastelloy UNS N Tubes
Hastelloy C-276 Tubes
Hastelloy B-2 Tubes
Hastelloy X Tubes
Hastelloy G-30 Tubes
Hastelloy C-22 Tubes
This tube is known for its versatility in resisting a wide range of corrosive chemicals, including sulfuric acid, hydrochloric acid, and chlorine gas. It is commonly used in chemical processing plants and other industrial applications where aggressive chemicals are present.
