Gayatri Tubes is a leading manufacturer, supplier, and wholesaler of SMO 254 Compression Tube Fittings. We also deal in all types of household stainless steel. SMO 254 compression is constructed with a chemical composition like silicon, niobium, molybdenum, phosphorous, chromium, manganese, carbon, iron, nickel, sulfur, copper and so on. This SMO 254 is made with mechanical properties like elongation, density, melting point, tensile strength, and yield strength.SMO 254 Compression Tube Fittings differs in size, shape, pressure rating, standards, dimension, and specification. SMO 254 tube fitting is available in different types like carpenter 20 front ferrules, SMO 254 street tees, SMO 254 back ferrules, SMO 254 male tee, carpenter 20 tube nut, and carpenter 20 female tee. These SMOs also have a different form in shape like elbow, adapter, tee, hex, nipple, union, cap, etc.
SMO 254 is applicable in many industries like gas processing, pulp & paper factory, pharmaceutical equipment, power generation, condensers, seawater equipment, petrochemicals and so on. SMO 254 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. SMO UNS S31254 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. SMO 254 contains niobium that helps it to stabilize against interangular corrosion and sensation. This SMO contains niobium has both the stainless and nickel characteristics that result in perfect use around the chemical processing. SMO 254 compressions help in welded fabrications to easily be used in the corrosive environments and generally without the use of post-weld heat treatments. This SMO 254 is having high cryogenic temperature resistance up to 1093 degrees Celsius with high strength and toughness.
SMO 254 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.
