A flange joint is a connection of pipes, where the connecting pieces have flanges by which the parts are bolted together. The principle of a flange is to apply a mechanical force by using bolts to preload the gasket until contact stress between flanges and gasket is sufficient to maintain a seal. Connection to the pipe is by welding or threading. To allow easy functionality and inter-changeability, these ASTM B564 Flanges are designed to have standardised dimensions which include ANSI, ASME, DIN, EN, BS, JIS. Flanges have major applications in Oil, Gas, Petrochemical, Ship-Building, Marine, Food, Dairy, Railways and other associated industries were piping systems are required.
Hastelloy Slip On Flange — Alloy 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 Flange prior to welding both inside and outside. We supply a wide range of slip-On Flanges in different dimensions and sizes.
Hastelloy Blind Flange — Alloy Flange with no borehole are known as Blind Flange and used to close the end of the pipe. Blind Flanges are supplied as threaded or welded from class 150lb to 2500lb.
Hastelloy Weld Neck Flange — Alloy Weld Neck Flanges are widely used in high-pressure piping systems and can be easily recognised by the long tapered hub. The size of the bore hole is usually equal to the size of the pipe.
Hastelloy Socket Weld Flange — Initially developed for small high-pressure piping systems a Socket Weld Flange is similar to Slip On Flange. The flange is installed by welding around the hub of the flange.
Hastelloy Threaded Flange — Threaded Flanges are used for special application where the flange 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 Lap Joint Flange — Lap-Joint Flanges are similar to Slip-On flanges and are generally used with Lap-Joint Stubs. This type of flange is highly used where the piping systems are disassembled from time to time.

Properties of Hastelloy C276 alloy
Hastelloy C276 Cold Forming
Annealed treatment is followed for every forming operations. For cold deformation at high-level, cold forming is done for the deformation process where cracking is a possibility because of mild forming. The cold forming process is used to restore the resistance to stress corrosion cracking. For most of the time, a solution anneal is recommended after the complete formed or annealed operation which helps to restore the material to its optimum condition and properties.
Hastelloy C276 Hot Forming
Hastelloy C276 can be hot-worked into various forms but they are more sensitive to the amounts and rates of hot-reduction with the austenitic stainless steels. During Hot working, all parameters should be taken into account. Special attention should be given to the temperature at which the alloy begins to melt. The high strengths of the Hastelloys at elevated temperature, their low thermal conductivity, and their hardening rate. Moreover, when the temperature is low in the hot working range of the metal, they are resistance to deformation is increased rapidly. So, while hot working practices that give heavy initial reduction followed by moderate final reductions, also with frequent re-heating gives the good result.
Hastelloy C276 Machining
Hastelloy C276 can be machined using conventional production methods at satisfactory rates. During the machining processes these alloys work harden rapidly, generate high heat during cutting, weld to the cutting tool surface and offer high resistance to metal removal because of their high shear strengths. Following are key points that should be considered during machining operations: Capacity, Tooling, Lubrication/Coolants, Drilling. The actual operating parameters are to serve only as a guide and are not to be taken as absolute values.
Hastelloy C276 Welding
Gas tungsten-arc welding, gas metal-arc welding, shielded metal-arc (coated electrode) welding, or resistance welding may be used. Minimum heat input consistent with adequate penetration reduces the chance of hot-cracking. Oxyacetylene welding should be avoided due to possibility of carburization. Hastelloy C-276 can be used in the as-welded condition in most chemical and petrochemical process equipment
Hastelloy C276 Heat Treatment
Wrought forms of Hastelloy C-276 are furnished in the solution heat-treated condition unless otherwise specified. Alloy C-276 is normally solution heat-treated at 2050 °F and rapid quenched. Parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation, if possible
