Alloy Steel Pipe Bends

Huge amount of Chromoly Tubing Bends Manufacturer in India

Kanak Metal & Alloys is a large scale supplier and distributer of different types of metal and metallic alloy products. We also specialize in chromium molybdenum alloys which are called the chromoly products. Our Chromoly Tubing Bends are one of the pipe fitting products that are extensively used in many piping applications. The chromium molybdenum content makes these bends suitable to be used with the same compositions of pipes and in much harsh environments. These are corrosion resistant, high temperature service pipes and fittings.

The Alloy Tube Bending is available in different sizes, shapes and grades. There are different types of manufacturing techniques as well. The Alloy Mandrel Bends are produced by bending the pipes after inserting a rod inside the pipe to make sure that the bending is even and smooth throughout the length of the bend. The most used of these pipes belong to the ASME B16.9 Alloy Pipe Bends standards which range from ½ inches to 48 inches in pipe diameter.


There are also different grades and types such as the Alloy Steel Pipe Bends which is of a specification of pipe fittings and is made up of butt weld. There are different demarcations like the ASTM A234 90 deg BW 3" sch 80 alloy steel seamless elbow which means that the product belongs to the A234 specification, has a 90 degree angle and belongs to the schedule 80 which is of high pressure capacities. Please contact us for any specific pipe bend needs.
