ASME B16.5 MSS SP-44 EN1092-1 BS3293 nickel alloy flange Hastelloy B2

1. nickel alloy flange Hastelloy B2 specification

2. ABOUT ALLOY B-2 flange chemical composition and mechanical property

Alloy B-2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B-2 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 B-2® is used where ferric iron, cupric ion and free chlorides are present.

With a high nickel content, Hastelloy B-2 is immune to chloride-induced stress corrosion cracking.

MECHANICAL & PHYSICAL PROPERTIES

3. All types of Hastelloy B2 flange application

Hastelloy B2 Slip On Flanges — Hastelloy B2 Slip On Flanges is slightly larger than the outer diameter of the pipe it is to be used with. The pipe is slipped into the Flanges prior to welding both inside and outside. We supply a wide range of slip-On Flanges in different dimensions, sizes and grades such as Hastelloy Slip On Flanges, Hastelloy Alloy Slip On Flanges, Hastelloy B2 Slip On Flanges, Hastelloy Alloy B2 Slip On Flanges.

Hastelloy B2 Blind Flanges — Hastelloy Blind Flanges with no borehole are known as Blind Flanges and used to close the end of the pipe. Blind flanges are supplied as threaded or welded from class 150lb to 2500lb. Hastelloy Blind Flanges, Hastelloy Alloy Blind Flanges, Hastelloy B2 blind flange

Hastelloy B2 Weld Neck Flanges — Hastelloy Weld Neck Flanges are widely used in high-pressure piping systems and can be easily recognise d by the long tapered hub. The size of the bore hole is usually equal to the size of the pipe. Hastelloy Weld Neck Flanges, Hastelloy Alloy Weld Neck Flanges, Hastelloy B2 Weld Neck Flanges, Hastelloy Alloy B2 Weld Neck Flanges

Hastelloy B2 Socket Weld Flanges — Hastelloy Socket Weld Flanges was Initially developed for small high-pressure piping systems a Socket Weld Flanges is similar to Slip On Flanges. Socket Weld flanges is installed by welding around the hub of the flanges. Hastelloy Socket Weld Flanges, Hastelloy Alloy Socket Weld Flanges, Hastelloy B2 Socket Weld Flanges, Hastelloy Alloy B2 Socket Weld Flanges.

Hastelloy B2 Threaded Flanges — Hastelloy Threaded Flanges are used for special application where the flanges can be assembled to the piping system by without welding. We specialise in all forms of threaded flanges and can supply it in multiple size range. Hastelloy Threaded Flanges, Hastelloy Alloy Threaded Flanges, Hastelloy B2 Threaded Flanges, Hastelloy Alloy B2 Threaded Flanges.

Hastelloy B2 Lap Joint Flanges — Hastelloy Lap Joint Flanges are similar to Slip-On flanges and are generally used with Lap-Joint Stubs. This type of flanges is highly used where the piping systems are disassembled from time to time. Hastelloy Lap Joint Flanges, Hastelloy Alloy Lap Joint Flanges, Hastelloy B2 Lap Joint Flanges, Hastelloy Alloy B2 Lap Joint Flanges.
