AISI 316/316H Reducer Pipe Fitting is a pipe fitting that connects two pipes with different diameters. Austenitic stainless steel alloy 316 or 316H is used as a material. It has excellent resistance to corrosion, high strength, and good weldability. It has a number of applications which include chemicals, petrochemical, oil and gas, power generation and marine. AISI 316/316H Stainless Steel ButtWelded Reducer Pipe Fitting has two types: concentric reducer and eccentric reducer. A concentric reducer has a common centerline and causes the pipe diameter to decrease from large to small while keeping a fixed centerline. An off center reducer has an offset centre line and reduces pipe size from larger to smaller by aligning one end of the fitting with one end of the pipe. As for the selection of concentric or eccentric reducer, it is up to the flow nature, pressure drop and alignment needs of piping system.
However, buttwelded reducer pipe fittings are used to join pipes of varying calibers and reduce the flow rate of fluids or gases. They are butt-welded to the ends of the pipes, producing a continuous and leak free joint. There are two types of buttwelded reducer pipe fittings: concentric and eccentric. A concentric reducer is an element with the common centerline, and when reducing from larger to smaller it has a constant centerline. An eccentric reducer features an offset axis that decreases the pipe size from greatest to smallest by associating one end of a fitting with one end of the pipe. The decision on whether to use concentric or eccentric reducer is based on the type of flow features, pressure loss and pipelines alignment. It is a high carbon variant of 316 stainless steel and has excellent resistance to oxidation and corrosion in the high temperature range. AISI 316/316H buttwelded reducer pipe fittings is used for high strength and wear resistant applications such as furnace parts, heaters etc., they are available according to the customer’s requirements in various sizes shapes and schedules.
Rexon Pipe fittings specialty is one of the types of stainless steel fitting that is a buttwelded Concentric Reducer pipe fitting. It has two apertures of varying sizes that link pipes of different diameters and maintain the centreline. It is commonly utilized to change the pipe diameter and flow rate among different piping systems.
Buttwelded Eccentric Reducer pipe fitting is a type of stainless steel fitting with slant centerline and two openings of different sizes that is manufactured by Rexon Pipe fittings.
Short-End Reducer pipe fitting is a type of stainless steel fitting with two openings of different sizes and a shorter end than standard reducers and is what Rexon pipe fittings specialize at.
Buttwelded Long-End Reducer pipe fitting is one of the stainless steel fitting types, which has two openings with different sizes and a longer end than regular reducers; Rexon Pipe fittings specialize in.
Stainless Steel buttwelded reducer pipe fitting specifications are AISI 316/316H, which the dimensional and tolerance and material grades of wrought austenitic stainless steel fittings used for pressure vessel applications.
