Gayatri Tubes is a leading manufacturer, supplier, and wholesaler of Alloy 20 Compression Tube Fittings. We also deal in all types of household stainless steel. Alloy 20 compression is constructed with a chemical composition like silicon, niobium, molybdenum, phosphorous, chromium, manganese, carbon, iron, nickel, sulfur, copper and so on. This alloy 20 is made with mechanical properties like elongation, density, melting point, tensile strength, and yield strength.Alloy 20 Compression Tube Fittings differs in size, shape, pressure rating, standards, dimension, and specification. Alloy 20 tube fitting is available in different types like carpenter 20 front ferrules, alloy 20 street tees, alloy 20 back ferrules, alloy 20 male tee, carpenter 20 tube nut, and carpenter 20 female tee. These alloys also have a different form in shape like elbow, adapter, tee, hex, nipple, union, cap, etc.
Alloy 20 is applicable in many industries like gas processing, pulp & paper factory, pharmaceutical equipment, power generation, condensers, seawater equipment, petrochemicals and so on. Alloy 20 is often used for general purposes like synthetic fibers, and plastics production. These products are perfect for use around phosphoric, nitric, and sulphuric acids. Also, they are often used in valves, fittings, pumps, pickling equipment, process piping, mixing tanks, heat exchangers, chemical processing, and fasteners, etc. Alloy UNS N08020 Compression Tube Fittings work at higher temperatures and high pressures with high strength. It is very useful in assembly and disassembly, with comparatively excellent corrosion resistance, easy to use and does not require soldering. Alloy 20 contains niobium that helps it to stabilize against interangular corrosion and sensation. This alloy contains niobium has both the stainless and nickel characteristics that result in perfect use around the chemical processing. Alloy 20 compressions help in welded fabrications to easily be used in the corrosive environments and generally without the use of post-weld heat treatments. This alloy 20 is having high cryogenic temperature resistance up to 1093 degrees Celsius with high strength and toughness.
Alloy 20 Compression Tube Fittings has to go through many tests after the productions like hardness test, flaring test, flattening test, chemical & Spectro analysis, pitting resistance test, mechanical test and many more.
