Product Description

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.

Threaded flange refers to a flange that is connected to the pipe by threads. When designing, it can be treated as a loose flange. The advantage is that welding is not required, and the additional torque generated on the cylinder or pipe when the flange is deformed is very small. The disadvantage is that the flange is thick and the cost is high. It is suitable for the connection of high-pressure pipelines.Threaded flange is a non-welded flange that has its inner hole processed into pipe threads and is connected to threaded pipes. Compared with flat welding flanges or butt welding flanges, threaded flanges are easy to install and maintain, and can be used on pipelines where welding is not allowed on site. Alloy steel flanges have sufficient strength, but are not easy to weld, or have poor welding performance, so threaded flanges can also be selected. However, when the pipeline temperature changes sharply or the temperature is higher than 260℃ and lower than -45℃, it is recommended not to use threaded flanges to avoid leakage.
