The ASME B16.9 is a standard that determines the different variables which are a set of recommendations directed towards the manufacturer of wrought alloy buttwelding fittings produced in a factory. These fittings comprise of components such as elbows, caps, crosses, tees, reducers etc. Most manufacturers construct these fittings in either a seamless manner or they are constructed by means of welding. These ASME B16.9 Seamless Fittings are required to conform to the values put forth by the ASME B16.9 standard including testing methods used, ratings, overall dimensions, tolerances that are given, as well as markings that are required to marked or engraved on these fittings. Although these ANSI B16.9 Seamless Fittings could be produced with their size ranging anywhere from DN 15 to DN 1200, the size chosen for the fittings will eventually be determined per the requirement of the industry or the buyer’s need. Dinesh industries is leading Seamless Fittings Manufacturer in India from last 25 years.

Seamless Fittings
Contrasting to welded fittings, Seamless pipe fittings, have a 20% higher ASME working pressures even if both the constructions use the same material and size. This is because seamless fittings have no welded seams. Apart from being one of the least costly product, an advantage of using the Carbon Steel Seamless Pipe Fittings includes its high strength, good toughness and shock resistant properties. However, carbon steels lack corrosion resistance properties. On the other hand, stainless steel seamless fittings offer superior corrosion resistance properties across a wide media in addition to retaining its high mechanical properties at elevated as well as low temperature environments.
