Kanak Metal & Alloys is a manufacturer and supplier of stainless steel pipes and fittings. The pipe fittings are used to connect pipes together or sometimes the fittings together. There are different types, shapes and sizes of fittings. The bends is one of the most used pipe fittings. There are short and long radius bends. The degree of bending differs as well. The 90 degree short radius bends manufacturer in india are used in pipelines to quickly change the direction by a 90 degree angle. The sr allows for sudden changes of direction and eliminates the need for much space.
Short radius Bend
Short radius 180 return bends
There are different Short Radius Pipe Bend Dimensions depending on the standards and specifications of the pipeline. The ASME B16.9 standard governs the pipes and fittings of diameter range ½ inches to 48 inches. There are other types and standards which have higher diameter pipes and fittings as well. The short radius bends could be used in place of short radius elbows as well.
As a Carbon Steel Short Radius Bend manufacturer we produce the elbows and bends at high qualities and standards. Sometimes a special type of bend is used to reverse the direction of fluid flow. These are called the Short radius 180 return bends because of the degree at which they turn the flow. These are also known as the Short radius u bends types because of the shape. Please contact us for further information on the products and pricing.
