Buttwelded Reducer Pipe Fitting, AISI 310H Stainless Steel is a pipe fitting that joins two pipes of varying diameters. A reducer pipe fitting shrinks the pipe from a bigger to a smaller bore However, a buttwelded reducer pipe fitting is included in the welding of both ends of the pipes forming a seamless and leak-free welded joint. AISI 310H is a high carbon version of 310 stainless steel with superior oxidation and corrosion resistance at elevated temperatures. AISI 310H stainless steel has higher strength and toughness than AISI 316S, with a better technological serviceability. It can be used for furnace parts, heat exchangers, oil burners as well as other applications where high strength is required. The high-quality raw materials and advanced technology are used to manufacture AISI 310H buttwelded reducer pipe fitting that is stainless steel. The pipe fitting is such that it conforms to the specifications of ASTM A403, ANSI B16.9, MSS SP-43, and MSS SP-79. The choice of pipe fitting by the customer determines the size, shape and schedule. Quality and performance tests are conducted on the pipe fitting before delivery to guarantee that a high-quality product is received and will stand up through years of service.
310H is highly carbon-modified 310 stainless steel that offers superior resistance to oxidation and corrosion under high temperatures. Among the available fittings are AISI 310H buttwelded reducer pipe fittings, which can be used in furnace parts, heat exchangers and oil burners that require high strength and endurance. These particular fittings are offered various sizes and schedule depending on customers’ orders.
Rexon Pipe fittings offers stainless steel Buttwelded Concentric Reducer pipe fittings. They have two opposite ends with varying sizes that connect pipes of different thicknesses and align the axis. These are commonly used to change the pipe diameter and flow rate of the most diverse piping systems.
Rexon produces and provides Buttwelded Eccentric Reducer pipe fittings that are stainless steel fittings characterized by having two ends with different diameters and a slanted centerline.
However, Hotweld Reducer pipe fittings are simply fittings made by Rexon Pipe fittings and supplied by the company called Rexon Pipe Fittings, which has two ends with different diameters and a shorter end than normal reducers, all made of stainless steel.
Rexon Pipe fittings involves in the manufacture and supply of Buttwelded Long-End Reducer pipe fittings’ stainless steel fittings that have two ends with different diameters and a longer end than normal reducers.
The specifications of Stainless Steel buttwelded reducer pipe fitting are based on 310H, which define the dimensions, tolerances, and material grades of forged and seamless tubular products made of wrought austenitic stainless steel.
