Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

Hastelloy C22 Flanges are a technique used by many industries in the connecting of pipes, valves, pumps and other equipment, into what is referred to as a piping system.

Pipe bending allows systems to minimize pressure changes while still routing materials through complex piping systems.

HASTELLOY(r) B-2 is a wrought nickel-molybdenum alloy that can be used in the ¡®as welded¡¯ condition.

Alloy N10675 is a high corrosion resistant nickel molybdenum Alloy. This alloy is characterized by a high resistance against hydrochloric acid and other reducing media in a wide range of temperature and concentration.

Nickel alloys are some of the most useful materials for manufacturing technically superior pipes and tubes for industrial applications.Nickel Pipe is a metal pipe that is made up of an alloy that has primarily nickel and other elements in its composition.

Alloy C-276 has excellent resistance to pitting and stress corrosion cracking. It is also one of the few materials that can withstand the corrosive effects of wet chlorine, hypochlorite and chlorine dioxide.

Hastelloy C-276 pipe fittings refer to factory-made wrought nickel alloy fittings manufactured to ASTM B366 UNS N10276. It can be designated as CRHC276(corrosion resistant fittings) or WPHC276(ASME pressure fittings). The fittings can be manufactured from pipe or tube of ASTM B619, B622, B626 UNS N10276, plate, sheet or strip of ASTM B575 UNS N10276, forging or bar of ASTM B564, B462, B472, B574 Gr. N10276. The Hastelloy C-276 fittings are mainly furnished in 3 connection types: butt welding, threaded, socket welding, covering a variety of standard specifications.
Since Alloy C-276 contains a high amount of nickel in its chemical composition, the metal is very ductile. Therefore forming it into various shaped Hastelloy C276 Pipe Fittings becomes very simple. Yet, this is not the only benefit offered by this alloy. Like many nickel containing alloys, the strength and corrosion resistance properties of this alloy make it one of the most sought after ones by Hastelloy Fittings Suppliers. The metal is capable of exhibiting superior resistance to pitting. Unlike highly ductile materials that tend to exhibit failure against stress corrosion cracking, on the application of a tensile load, the Alloy C276 Pipe Fittings are able to withstand such levels of stress.

The chemical composition of Hastelloy B2 includes a very small amount of carbon content. Hence, the flanges produced from Hastelloy grade B2 tends to resist the formation of grain boundary carbide precipitates during welding in the weld heat-affected zone.

Hastelloy X pipe bend is widely used for a variety of chemical processing parts, including retorts, pyrolysis tubing, and muffles due to its exceptional resistance to stress-corrosion cracking.

The applications range from chemical, petrochemical, power generation and OEM manufacturing industry as well other applications where vibration, high pressure or extremely corrosive conditions exist.

These salts may develop when hydrochloric acid comes in contact with iron and copper. Therefore, if this alloy is used in conjunction with iron or copper piping in a system containing hydrochloric acid, the presence of these salts could cause the alloy to fail prematurely.

Hastelloy X is a nickel base alloy that possesses exceptional strength and oxidation resistance up to 2200¡ãF. This nickel steel alloy has also been found to be exceptionally resistant to stress-corrosion cracking in petrochemical applications.

Hastelloy B3 Flanges has great resistance to cutter line, and heat affected zone attack.

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids.

Hastelloy C-276 alloy can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can be successfully deep-drawn, spun, press formed or punched.

Hastelloy C276 is an extremely versatile material that has been used in a variety of harsh environments. It exhibits corrosion resistance to chloride-containing media, organic acids, oxidizing media, reducing acids, seawater and brine, and sulphur-containing flue gas. Hastelloy C276 replaces Alloy C (UNS N10002), which has slightly lower chromium and molybdenum contents. The high nickel, molybdenum and tungsten contents make them expensive compared to austenitic stainless steels. It is by far the most popular super alloy.

This nickel-molybdenum alloy is typically used under extreme reducing conditions and has a much lower composition of carbon, silicon and iron than Hastelloy B (Alloy B). Screws made from this alloy are also known as UNS N10665 fasteners.

Process piping systems rarely travel in a straight line from process to process.

The flange is second most used joining method after welding. Flanges are used when joints need dismantling. It provides flexbility for maintenance. Flange connects the pipe with various equiment and valves. Breakup flanges are adde din the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrelated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls ae required in the selection and application of all these elements to attain a joint, which has acceotable leak tightness.

Used when large radius bends or curves are required, this method passes a piece of pipe or tube through a series of three rollers in a pyramid configuration to achieve the desired curve.
