Product Description
C276 Introduction
Super alloys or high performance alloys are available in a variety of shapes and contain elements in different combinations to obtain a specific result. These alloys are of three types that include iron-based, cobalt-based and nickel-based alloys. The ickel-based and cobalt-based super alloys are available as cast or wrought based alloys according to composition and application.
Super alloys have good oxidation and creep resistance and can be strengthened by precipitation hardening, solid-solution hardening and work hardening methods. They can also function under high mechanical stress and high temperatures and also in places that require high surface stability. HASTELLOY(r) C276 is a wrought corrosion-resistant alloy that resists the development of grain boundary precipitates that degrade corrosion resistance.
The following datasheet provides an overview of HASTELLOY(r) C276..
C276 Forging Butt Welding Olet Introduction
The branch pipe seat weld olet, also known as the pipe base or forged branch pipe joint, is a commonly used forged reinforcing pipe fitting in high-pressure pipeline systems. It is mainly used to lead out branch pipes from the side wall of the main pipe, replacing the traditional opening and welding three-way fittings, and serves the functions of opening hole reinforcement and diversion of the branch pipe. It complies with ASME B16.11 and national standards such as GB/T 19326. The product is made from high-quality carbon steel, stainless steel, and alloy steel round steel, and is forged as a whole. The structure is tight, and the strength is much higher than that of the on-site welded branch pipe, which can effectively disperse the stress at the opening hole and prevent the main pipe from cracking under pressure after the opening hole. One end of the branch pipe seat fits the outer wall of the main pipe, and can be firmly welded to the main pipe by butt welding or socket welding. The other end is reserved for socket or thread interfaces, which can directly connect valves, instruments, and small branch pipes. The specifications are complete, and it is compatible with NPT threads, socket welding, and butt welding connection forms. The production process includes cutting, high-temperature forging, numerical control fine machining, size verification, and non-destructive testing. Cracks and defects are strictly inspected. The branch pipe seat is easy to install, has reliable reinforcement effect, outstanding sealing performance and pressure resistance performance, and is widely used in high-pressure working conditions such as petrochemicals, power plants, natural gas, pressure vessels, heating networks, etc. It is a core component for branch pipe modification, pressure gauge pressure tapping, and small pipe diversion.

C276 Forging Butt Welding Olet Product processing
1.Material Cutting and Selection
Select round steel bars (carbon steel, stainless steel, alloy steel), reserve forging allowances according to the finished product dimensions, cut the billets to a fixed length using a sawing machine, clean the burrs on the end faces, inspect the appearance and material of the raw materials, and remove unqualified raw materials with inclusions, cracks, etc.
2. High - temperature Heating
Send the billets into an intermediate - frequency heating furnace for constant - temperature heating to the appropriate forging temperature, ensure uniform overall heating, control the temperature and time to prevent over - burning and severe oxidation, and endow the metal with good plasticity for easy forging and forming.
3. Die Forging and Forming
Place the hot billets into a special branch pipe tee mold and perform overall forging through a forging press. Forge the tee body base and the main body of the branch pipe in one press to form an integrated base with an arc that fits the curvature of the main pipe. After forming, cut off the peripheral flash waste and preliminarily correct the shape.
4. Cooling and Rough Finishing
Cool slowly or in the air according to the material requirements. For stainless steel, strictly control rapid cooling to prevent stress cracking. After cooling, perform rough grinding to trim the forging protrusions and irregular parts and ensure the smoothness of the base arc.
5. CNC Precision Turning
Finely machine the arc surface and end face of the base on a lathe, machine the upper end socket or NPT/BSP external threads, and turn the welding bevel. Strictly control the aperture, thread accuracy, and arc size, and use go - no - go gauges to check the qualification of the threads.
6. Non - destructive Testing
Conduct magnetic particle and penetrant testing on high - pressure products to check for cracks and interlayer defects in the forging parts and the root of the threads. At the same time, verify all dimensions, specifications, and pressure ratings.
7. Surface Treatment and Warehousing
Galvanize or blacken carbon steel for rust prevention, perform pickling and passivation on stainless steel to remove the oxide scale. Engrave the specifications on qualified products with steel stamps, pack them by category, and store them in the warehouse.
