In case you are searching for a top-notch and longtime use pipe fitting that can tolerate high temperatures and pressures, the AISI 321/321L stainless steel butt-welded reducer pipe fitting may be what you need. This form of fitting is in austenitic stainless steel alloys and titanium, which improves its intergranular corrosion resistance and oxidation. The AISI 321/321L stainless steel butt-welded reducer pipe fitting can be applied to refinery equipment, chemical processing, expansion joints and aerospace industries. It can also be heat treated by annealing and has excellent weldability. The AISI 321/321L butt-welded reducer pipe fittings are manufactured in various sizes and schedules, and they can be made to your specific order. Each end has a butt weld that creates a strong and leak-proof connection. The AISI 321/321L stainless steel butt-welded reducer pipe fitting is an affordable and dependable product that will meet your needs in terms of piping.
There is a stainless steel pipe fitting known as AISI 321 buttwelded reducer pipe fitting, which is used to join pipes with different bore diameters. A reducer pipe fitting consists of two pipe ends of different diameters, the larger one and the smaller one for the pipes. The reducer may either be concentric or eccentric depending on how axes of the pipes are aligned. AISI 321 is a stainless steel grade with superior corrosion resistance, with especially high resistance to acids and chlorides. It is also mechanically strong and weldable. The AISI 321 buttwelded reducer pipe fitting under consideration is ideal for high-pressure and temperature applications including chemical, petrochemical, oil and gas, and power generation industries.
Rexon Pipe fittings provides Buttwelded Concentric Reducer pipe fitting, which is one type of stainless steel fitting. It also has two ends of different sizes through which pipes of varying diameters fit and that have a straight centerline. Primarily, it is applied for the adjustment of pipe size and flow velocity in different piping systems.
Rexon Pipe fittings supply a buttwelded eccentric reducer pipe fitting that is a stainless steel fitting with two ends having different diameters and a slightly off-center line.
Rexon is able to ship Buttwelded Short-End Reducer pipe fitting, a shortened stainless steel fitting with two ends that have different diameters.
The Buttwelded Long-End Reducer pipe fitting belongs to the category of stainless steel fitting having different outer ends and a longer end compared to the common reducers; they are delivered by Rexon Pipe fittings.
Fitting Specifications are based on AISI 321/321H, which define the dimensions, tolerances, and material grades for wrought austenitic stainless steel fittings that are formed from forged and seamless tubular products.
