Hastelloy Buttweld Fittings

Hastelloy buttweld fittings are carefully developed to withstand stringent environments including high temperature and corrosive environments. Buttweld fittings are required in various applications that require high performance industrial use, such as chemical processing, power generation, and marine engineering. When you consider the longevity of performance with buttweld fittings made of Hastelloy, they are relatively forgiving with mechanical performance and relatively easy to weld.

What are Hastelloy Fittings?

Hastelloy fittings are specific pipe components created from alloy materials resistant to corrosion-electrochemically, such as Hastelloy C22, C276, and other high quality grades. Hastelloy fittings connect, divert or control flow in a piping system and they are especially useful for applications suffering from aggressive chemicals, high pressure, and high temperatures. Compared to stainless steels, Hastelloy alloys have higher nickel and molybdenum concentrations resulting in much higher resistance to stress corrosion cracking, pitting, and crevice corrosion.

Hastelloy Seamless Buttweld Pipe Fittings

Our buttweld pipe fittings made from Hastelloy are also seamless, are made to tighter tolerances than what is common for items in their category, giving them a more accurate shape, with practically zero chance of leaks, and they are also stronger than common pipe fittings. Due to their characteristics, they become the perfect solution for anything where failure is not an option, such as oil and gas, marine and chemical processing. However, not all of our seamless buttweld pipe fittings made from Hastelloy are the same. Some, for example, have 90 degree angles, and these types are called elbows.

The mechanical properties of Hastelloy buttweld pipe fittings are very good for harsh applications. Hastelloy has a high tensile strength, good elongation, and very good stress corrosion cracking and pitting resistance. The mechanical stability of Hastelloy across a temperature range provides confidence that these fittings will return to their proper fit, after extreme environmental conditions. These exceptional properties in a fitting will allow the fittings to be used well in the extreme corrosive environment of chemical processing and high-pressure systems with confidence.

Hastelloy buttweld fittings are also defined by a specific chemical composition which is collectively developed to improve corrosion resistance and mechanical properties. Incorporating performance-enhancing elements that include nickel, chromium, molybdenum, and tungsten, these fittings offer a balanced alloy that can withstand rigorous chemicals and extreme temperatures. When forming a blend such as Hastelloy, researchers have studied the performance of alloys and forged an excellent chemical composition that produces solid results in industrial applications as well as longevity in the most extreme applications.
