Kencotube is one of the leading manufacturer, stockiest & trader of high quality of Alloy 20 Butt Weld Pipe Fittings, which is an iron-base, austenitic alloy with excellent corrosion resistance to a number of different media. Alloy 20 Pipe Fittings was originally designed for use in sulfuric acid related applications; however, it is now frequently used in a wide variety of industries. Alloy 20 Elbow Pipe Fittings can be formed by either hot-working or cold-work using traditional methods. Hot forged material should be heated between 2100 Degree F and 2250 Degree F with careful temperature control insuring that Alloy 20 long Radius Elbow Pipe Fittings not fall below 1800 Degree F prior to forging. Although originally designed for use in sulfuric acid related industries, Alloy 20 Tee Pipe Fittings is now a popular choice for a wide variety of industries including the chemical, food, pharmaceutical, and plastics industries.
In addition, Alloy 20 Equal Tee Pipe Fittings is used in heat exchangers, mixing tanks, metal cleaning and pickling equipment, and piping. Application of Alloy 20 Unequal Tee Pipe Fittings could result in real cost savings when carefully compared to higher-cost alloys to determine if the necessary resistance is obtained in the chosen media. Applications of Alloy 20 Reducer Pipe Fittings are limited to a maximum temperature of 1000 Degree F per ASME. Meanwhile, hot forming in Alloy 20 Pipe End Cap Butt Weld Fittings should be in the range 1400Degree F-2150 Degree F (760Degree C-1175 Degree C).
