Hastelloy B2 Pipe Fittings

Hastelloy B2 Pipe Flanges, Hastelloy B2 Slip on Flanges, Hastelloy B2 Threaded Fittings, Hastelloy B2 Socket weld Fittings

We are one of the leading manufacturer and supplier of stainless steel pipe fittings, we offers a range of Copper Nickel Pipe Fittings such as Hastelloy C22 elbow, Hastelloy reducer, Hastelloy tee, Hastelloy stub ends, Hastelloy pipe bends, and Hastelloy cross.

Some important characteristics of Hastelloy B2 Pipe Fittings are such as it is high resistance to consistent attack, wonderful restricted corrosion resistance, outstanding stress corrosion cracking resistance, first-rate resistance to acids such as sulphuric, nitric, hydrochloric, hydrofluoric, chromic, etc., high resistance to oxidation at soaring temperatures, and no difficulty of fabrication and welding. Hastelloy is a nickel-molybdenum-chromium super-alloy by means of an accumulation of tungsten designed to have an exceptional corrosion resistance in a broad range of harsh environments. Hastelloy is applied to different highly corrosion resistant metal alloys.

We also supplies and stocks a full range of hastelloy pipes to match our present production range of butt weld pipe fittings and flanges. Hastelloy pipes can be supplied in made to order length sizes and also fabricated or machined to meet up your piping requirements.

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 B2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Premature failure may occur if alloy B2 is used where iron or copper is present in a system containing hydrochloric acid.

Fabrication and Heat Treatment

Hastelloy B2 can be machined using conventional machining methods which are used for iron-based alloys. Machining operations are performed using commercial coolants. High-speed operations such as grinding, milling or turning, are performed using water-base coolants. Hastelloy B2 is welded using gas-tungsten arc welding, shielded metal-arc welding, gas metal-arc welding, and submerged-arc welding methods.
