Prashant Steel is an industry-leading manufacturer and supplier of 3D Bend Pipe twists. 3D bends are pipe twists, the width of which is three times that of the outer thread. A wire can be twisted in multiple directions and angels. Nevertheless, the shape of an elbow varying from two degrees 90 degrees is some of the most normal and easy bends. Others are the U-bends which have a 180-degree curve. At Prashant Steel, we produce these 3D bends using the finest quality raw materials and the latest manufacturing processes.

The 3D Bend manufacturing process involves the operation of machinery and hydraulic power. Pipe or tube bending devices are usually operated by humans, supported by hydraulics, or even driven by pneumatic. We at Prashant Steel produce these high-performance 3D bends using one of many common methods including ram bending, rotary draw bending, compression bending, and three-roll bending, the pipe can be custom-bent with presses or more complicated devices. For each pipe size and each specific bend radius, separate dies are typically required, except on more complex machines.

A 3D bend is a turn, where the curve length is equivalent to 3 times the pipe diameter. It’s a finer bend than a 1.5D bend that looks almost like a normal 90-degree right angle but it’s a stronger bent than a 5D bend that looks like a straight curve between two perpendicular parts. They are generally used in industries like Automotive Exhaust Systems, Structural Frames, Furniture Manufacturing, Plumbing and Gas and oil pipelines.

There are some advantages of replacing elbows with 3D bends. The 3D bends can be custom designed, so an exact elbow fitting would not have to be procured by a company. The 3D bend can instead be shaped to the exact specifications required. The welds that are associated with an elbow fitting are often eliminated by a 3D bend, reducing failure points. This would also remove the need for weld testing that would be connected to elbow fittings. Choosing a 3D bend over an elbow fitting also proves to be the most cost-effective, effective, quickest alternative that offers high structural integrity as well.

Applications of the 3D Pipe Bends

Industries that require steady flows of chemicals and extracts to manufacture their petroleum products, such as the petro-chemical industry, often turn to 3D bends to ensure the best piping processes. In the oil-field industry, another common usage of 3D pipe bends is To extract petroleum from the earth, the oil field industry relies on accurate pipe bending in both moving and stationary pipes. Without the use of correct pipe bending in the oil field industry, there will be a lot of losses. In the aerospace industry, too, custom pipe bends are relied on. When it comes to space exploration, pipes have to be twisted with great precision and accuracy. In the aerospace industry, the pipe bends used must also endure the harsh conditions encountered in outer space.
