hastelloy pipe

Hastelloy C-22 can be used in conjunction with Hastelloy C-276 to prevent joint corrosion. Its composition is nickel-chromium-molybdenum-tungsten, giving it some of the resistance that is characteristic of C-276. The metal is excellent against overall and localized corrosion, along with chemical, oxidation, and reducing environments. Tests in environments containing wet chlorine and nitric acid have also proved that Hastelloy C-22 shows exceptional resistance. However, one unique characteristic is its weldability, which allows the metal to be used as a filler in many cases where other metals have failed to stop corrosion. These characteristics make Hastelloy C-22 commonly applied in chemical productions for food and beverages and pharmaceutical tools.

This nickel steel alloy has also been found to be exceptionally resistant to stress corrosion cracking in petrochemical applications. Matrix stiffening provided by the molybdenum content results in high strength in a solid-solution alloy having good fabrication characteristics. Although this nickel alloy is primarily noted for heat and oxidation resistance it also has good resistance to chloride stress-corrosion cracking, carburization, and excellent resistance to reducing or carburizing atmospheres. Two common conditions that often lead to early failure in high temperature alloys, carburization and nitriding, Hastelloy X resists.

Hastelloy B2 pipes are available in custom sizes and thicknesses according to customer requirements. They are readily available in national and international standards at very effective prices. It is a strengthened nickel alloy used under extreme reducing conditions. They are made of high-quality raw materials. It comes in various grades and forms.

Hastelloy C-276 Alloy has excellent resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions.

HASTELLOY B-3 alloy (UNS N10675) is an excellent resistance alloy to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B-3 alloy has a special chemistry designed to achieve a level of thermal stability greatly superior to that of its predecessors, e.g. HASTELLOY B-2 alloy. B-3 alloy has excellent resistance to pitting corrosion, to stress-corrosion cracking and to knife-line and heat-affected zone attack.

It is used in flue gas desulfurization systems because of its excellent resistance to sulfur compounds and chloride ions encounted in most scrubbers. C-276 alloy has excellent resistance to pitting and to stress-corrosion cracking. It is also one of the few materials that withstands the corrosive effects of wet chlorine gas, hypochlorite, and chlorine dioxide.

Hastelloy C-22 has exceptional resistance to a wide variety of chemical process environments, including strong oxidizers such as ferric and cupric chlorides, hot contaminated media (organic and inorganic), chlorine, formic and acetic acids, acetic anhydride, and seawater amd brine solutions.

Alloy C 276 (UNS N10276/ 2.4819) is known for its corrosion resistance in a variety of corrosive media. The high molybdenum content imparts resistance to localized corrosion such as pitting. Low carbon minimizes carbide precipitation during welding to maintain the resistance of the welded joint heat affected zone to intergranular erosion. It is used in chemical processing, pollution control, pulp and paper, industrial and municipal waste treatment, and recovery of “sour” natural gas. Applications in air pollution control include stack liners, ducts, dampers, scrubbers, stack gas reheaters, fans and fan guards. In chemical processing, the alloy is used to make components such as heat exchangers, reaction vessels, evaporators and transfer piping.
