Alloy N (UNS N10003) is a nickel-base alloy that was invented at Oak Ridge National Laboratories as a container material for molten fluoride salts. It has good oxidation resistance to hot fluoride salts in the temperature range of 1300 to 1600°F (704 to 871°C).HASTELLOY N alloy has good oxidation resistance in air. It shows promise for continuous operations at temperatures up to 1800°F (982°C). Intermittent use at temperatures up to 1900°F (1038°C) may also be possible. No discernible oxidation could be measured for the alloy at temperatures up to 1200°F (649°C).HASTELLOY N alloy can be supplied, to order, in the forms of sheet, plate, and bar.
The Butt Welding Olet is a reinforced pipe fitting used for branch pipe connection that has been widely used abroad in recent years. It replaces the traditional branch pipe connection types such as reducing tees, reinforcement plates, and reinforced pipe sections. It has outstanding advantages such as safety and reliability, reduced cost, simple construction, improved medium flow, series standardization, and convenient design and selection. It is increasingly widely used in high-pressure, high-temperature, large-diameter, and thick-walled pipelines, replacing the traditional branch pipe connection method. The main body of the branch seat is made of high-quality forgings, and the materials used are the same as the pipeline materials, including carbon steel, alloy steel, stainless steel, etc. The branch pipe and the main pipe are welded. The connection between the branch seat and the branch or other pipes (such as short pipes, threaded plugs, etc.), instruments, and valves includes butt welding, socket welding, and threaded. There are six types of branch seats: butt-welded branch seats, socket branch seats, threaded branch seats, short-tube branch seats, miter branch seats, and elbow branch seats.
