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.

Butt-welding elbow is a steel hot-pressed or forged elbow, and its connection form is to directly weld the elbow to the steel pipe. Butt-weld elbows can be divided into long radius butt-weld elbows and short radius butt-weld elbows according to their curvature radius. The curvature radius of the long radius butt-weld elbow is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D. The curvature radius of the short radius butt-weld elbow is equal to the outer diameter of the pipe, that is, R=1D. In the formula, D is the diameter of the butt-weld elbow, and R is the curvature radius. If there is no special instruction, a 1.5D elbow is generally selected.
