JN ALLOY supplies Alloy 20 Pipe, ASTM B622 UNS N10665 Tube, Alloy 20 Tube, 2.4660 Alloy 20 Tube, Alloy 20 Pipe, Alloy 20 Material, Alloy 20 Price, N08020 Tube, Alloy 20 Tubing, Alloy 20 Seamless Tubing.

Niobium stabilized Alloy 20 Pipe is also referred to as carpenter 20 or known by its trade name UNS N08020. Developed to exhibit good corrosion resistance properties, the Carpenter Alloy is an alloy which has exceptional resistance to sulfuric acid. The content of copper added to the Alloy 20 Seamless Pipe is what protects this metal grade against sulfuric acid. Hence, the Carpenter 20 Pipe UNS N08020 Pipe finds use in key industrial sectors such as chemical, petrochemical, power generation, as well as the plastic industries. Carpenter 20 B729 Pipe produced under the ASTM B729 specification is generally furnished in a stabilized annealed condition. As one of the foremost Alloy 20 Pipe Manufacturers, we recommend these pipes to be used in those applications which are susceptible to pitting and chloride ion corrosion. In fact, we highly recommend using the Alloy 20 Welded Pipe in those areas where grade 316 alloy is prone to stress related corrosion cracking.

Jinie Technology (Jiangsu) Co., LTD is a leading supplier and manufacturer of alloy 20 tubing. Alloy 20 Nickel Tubing has nickel, chromium, carbon, copper, molybdenum, manganese, silicon, niobium and other elements in its chemical composition. The copper content is mostly responsible for the sulfuric acid resistance. There are seamless and welded tubes. The UNS N08020 Seamless tube can range from 0.375 inches to 1 inches in outer diameter where the welded tube can range from 0.125 inches to 1 inches. Also the wall thickness varies to seamless and welded pipes. Pipes available in the market are made up of various materials such as alloys and metals. One such pipe is the Alloy 20 Pipe that is made up of an austenitic steel material Alloy 20 Pipe manufacturers stabilize these pipes by adding niobium to the alloy. This helps in resisting intergranular corrosion. It offers good resistance to phosphoric acid, sulfuric acid, nitric acid, and aqueous salt solution. Alloy 20 Pipes are the best solution for applications wherein chloride stress corrosion cracking is an issue. However one needs to be cautious with Alloy 20 Seamless Pipe in chloride ion containing environment as it increases the corrosion rate rapidly.

Alloy 20 pipe has high mechanical properties and is quite simple to make. While the alloy was designed for use in industries using sulfuric acid, it is most usually seen in the chemical processing industry. Manufacturing also involves the use of pharmaceuticals, foods, petroleum, chemicals, polymers, explosives, synthetic materials, and a variety of other materials.

Furthermore, this exceptional alloy is required in high-temperature exchangers, combining tanks, metal washing, dissolving equipment, and pipes. When compared to higher nickel-based alloys, Alloy 20 Pipe may offer cost benefits when making standard stainless steel.

To begin with, Alloy 20 pipes are commonly used in chemical and related industries, heat exchangers, food and dye manufacturing, SO 2 scrubbers and other harsh environments, pickling racks, tanks, and valves.

Alloy 20 Pipes are used in a variety of industrial applications, including food manufacture, construction, the chemical industry, petrochemicals, pharmaceuticals, oil exploration, power generation, the pulp and paper industry, condensers, heat exchangers, and so on.

Chemical production, petrochemical and refining, maritime, pharmaceutical, and food processing are all applications for alloy 20 pipes. End-use applications include storage facilities, mixing tanks, agitators, pump and regulator modules, food processing equipment, fasteners, and fittings. According to ASME, applications are limited to a maximum temperature of 1000 degrees F. It is also necessary to determine if the desired corrosion resistance can be attained within the given environment.
