Uses of Alloy 20 Pipe

Alloy 20 is one of the stainless steels known as “Super” that was engineered for optimum acid attack resistance. The content of nickel, chromium, molybdenum, and copper leads to its overall resistance to the cracking and general pitting attack of chloride on stress corrosion. With columbium, the alloy is stabilized to eliminate carbide precipitation during welding.

It has good mechanical characteristics and can be manufactured with relative ease. While the alloy has been developed for use in industries connected to sulfuric acid, it is commonly used in the chemical processing industry. Pharmaceuticals, meats, oil, solvents, plastics, explosives, synthetic fibers, and many other items are also used for manufacturing.

Besides, in high-temperature exchangers, combining tanks, metal cleaning, and also pickling tools and piping, this superb alloy is required. When carefully compared to higher nickel-based alloys, Alloy 20 Pipe can provide possible cost savings when manufacturing regular stainless steels.

What are the salient features of Alloy 20 Pipes?

The Alloy 20 pipes have some very good properties which you should know about. They are as follows:

  • They have superior resistance to stress-corrosion cracking in boiling 20 to 40% sulfuric acid.
  • Alloy 20 pipes also have excellent general corrosion resistance to sulfuric acid as well as resistance to chloride stress corrosion cracking.
  • They also have very good mechanical properties, fabricability, and minimal carbide precipitation during welding.

What are the uses of Alloy 20 Pipes?

Let us know what the uses of these Alloy 20 pipes are.

To begin with, the typical applications of Alloy 20 pipes are they are used in Chemical and allied industries, Heat exchangers, Food and dye production, SO 2 scrubbers and other severe environments, pickling racks, tanks, and valves.

Alloy 20 Pipes are used in many industrial applications such as food manufacturing, construction, chemical industry, petrochemicals, pharmaceuticals, oil exploration, power generation, pulp and paper industry, condensers, heat exchangers, etc.

Alloy 20 pipes are used in several fields, including chemical manufacturing, petrochemical and refining, marine, pharmaceutical, and food processing. Storage tanks, mixing tanks, agitators, pump and valve modules, food processing equipment, fasteners and fittings are end-use applications. Applications are restricted to a maximum temperature per ASME of 1000 degrees F. It is also important to decide if, within the given environment, the required corrosion resistance can be achieved.
