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.
Blanks Figure 8 Blanks Flange is a pipe fitting, which is mainly used for easy maintenance. You can know its specific shape by painting the upper part of the "8" black. It is half a blind plate and half an iron ring. It is often used in pipeline flanges that need to change the process. The main materials are carbon steel, stainless steel, and alloys. It can be selected according to the pipeline pressure level and pipeline medium. It is usually used on pipelines with larger diameters. Usually, one end of the flange is used to occupy the spacing to keep the pipeline unobstructed. When necessary, it is replaced with a blind plate of the same thickness at the other end to cut off the pipeline. Avoid forced expansion of the pipeline due to temporary replacement of other blind plates, affecting the entire system.
