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 socket welding couping is a pipe connector machined after forging round steel or steel ingot. Its connection form is socket welding (Socket Welding-SW). The steel pipe is inserted into the socket hole for welding. Therefore, it is called "socket pipe clamp". The main manufacturing standards are ANSI/ASME B16.11 and GB/T 14383-2008. The varieties of socket pipe clamps include double socket pipe clamps and single socket pipe clamps. Among them, the double socket pipe clamps are divided into equal diameter and different diameter, and the different diameter double socket pipe clamps are also divided into concentric and eccentric. Socket pipe clamps can be widely used in pipes of different diameters, including single-way, three-way, four-way, etc., and can also be used for water meters and valves. Due to the use of the socket structure, the pipe joint reduces the cost, is extremely convenient to install, use and maintain, and has a very high leak-proof ability, and has great market prospects.
