Pipe Bend Manufacturer & Supplier in Europe

What Exactly is Pipe Bend?

A pipe bend is a tool for changing the direction of fluid flow and producing an offset in the flow. The significance of pipe bends lies in their ability to facilitate the movement of fluid in various directions, a necessity in modern pipelines. The types of pipeline bends are fashioned through hot and cold rolling procedures, including compression bending, rotary draw bending, roll bending, and mandrel bending. As a top Pipe Bend Supplier in Europe, we offer a range of sizes to meet project requirements. It is imperative to identify the appropriate use of the Bend Dn150 for a successful operating system.

Why Pipe Bend Used In Pipeline?

The Steel Pipe Bend is a specialized component that is primarily intended to modify the flow characteristics within a pipeline. Unlike other pipe fittings, these bends do not necessitate welding and exhibit lower friction, resulting in a smoother flow. In complex piping systems, a 50mm Pipe Bend can effectively reduce routing pressure changes. Furthermore, these bends are straightforward to install and connect. The Schedule 40 Pipe Bends are highly flexible and exhibit exceptional thermal expansion properties, making them an excellent choice for various applications.

Why Use Bent Pipes?

The process of pipe bending enables complex piping systems to route materials while minimizing pressure changes. Due to the fact that most bent pipes do not modify the ends of the piping, they can be easily integrated into processing systems using conventional welding processes, flanges, or other connection methods.

Furthermore, the extensive range of pipe bend sizes and materials renders them appropriate for routing a diverse array of substances, including hot or caustic liquids, as well as maintaining pressure and movement in high viscosity liquids or those containing suspended solids. This is exemplified in the case of Oil Sands slurry lines, which contain a high concentration of silica sand.

What is The Pipe Bending Process?

The SS Pipe Bend machine uses a rotary draw to bend pipes. The pipes can be heated or not depending on their thickness and diameter. Mandrels are put inside the pipes and then they are bent to make the Stainless Pipe Bend. The machine must make sure that the pipe stays the same thickness and diameter throughout the bend. The mandrels stay inside the pipe to keep the diameter from getting smaller. But, the outside of the pipe may have some differences in thickness.

Production Process of Pipe Bend

• Pipe bend manufacturing comprises numerous important procedures to assure the fabrication of precise and dependable components. Initially, the raw material, usually steel pipes or tubes, is inspected for quality and dimensional correctness.
• Once authorized, the pipe is heated to the necessary temperature to allow for bending without affecting structural integrity. Depending on the material and final product criteria, several bending methods can be used, such as hot bending, cold bending, or induction bending. Hot bending is the process of heating the pipe to a specified temperature and then shaping it with bending machines or dies to get the correct angle. Cold bending uses hydraulic or mechanical presses to bend the pipe without the requirement for preheating, making it ideal for smaller bends.
• Following bending, the pipe bend may go through further operations such as heat treatment, straightening, or end finishing to satisfy specific needs. Heat treatment can be used to reduce residual stresses created during the bending process and enhance the mechanical qualities of the pipe bend.
• Straightening operations, such as hydraulic or mechanical methods, are used to rectify deviations from the required shape while maintaining uniformity and alignment. End finishing procedures such as beveling, threading, or welding preparation may also be used to aid in assembly and connection with adjacent components. Strict quality control methods are applied throughout the manufacturing process to ensure that the pipe bend's dimensional correctness, surface integrity, and mechanical qualities are by industry standards and client requirements.

Common Pipe Bending Methods

• Cold Bending Methods
• Rotary Draw Bending:

  It is a process whereby a pipe or tube is bent through the use of a combination of dies and other components that operate in a rotary fashion. This rotary action draws the pipe or tube forward, resulting in the desired bend. Additionally, mandrels may be employed in the process of Rotary Draw Bending.

• Mandrel bending:

  It involves the insertion of a mandrel into a tube or pipe during the bending process, particularly when working with materials possessing thinner walls. This technique serves to prevent the occurrence of defects in the bend, such as rippling, flattening, or collapse.

• Compression Bending:

  The process of bending a pipe or tube involves the utilization of a stationary die, while a counter die is employed to bend the material around the stationary die.

• Roll Bending:

  This technique is employed in situations where there is a need for bends or curves with a substantial radius. It involves the passage of a pipe or tube through a set of three rollers arranged in a pyramid configuration, thereby achieving the desired curvature.

• Hot Bending or Induction Bending

Although there exist slight variations in different hot pipe bending techniques, the majority of them are categorized as induction bending. This process involves the precise heating of the pipe through an induction heating coil prior to the application of pressure to achieve the desired bend. Unlike cold bending methods, induction bending requires significantly less physical force and can produce bends of comparable or superior quality without the use of filler materials, mandrils, or other additions to prevent distortion. While it reduces diameter reduction at the bend site, induction bending results in some changes in pipe thickness. Typically, the intrados, or inner section of the bend, will become thicker, while the extrados, or outer section of the bend, will become thinner. This technique is primarily utilized in large diameter piping and tubing and long radius bends, but it also has applications in smaller piping diameters and short radius bends.

What is the Method for Determining the Radius of a 90-degree Bend?

The bends' angles commonly measure 90° and may possess either a short or long radius. The Stainless Steel Long Radius Bends are seldom encountered. The internal radius is determined by the formula [(Dw/2/2) + Dp2]/Dp x 2, where Dp represents the depth of penetration, and Dw denotes half the width of the die. The Stainless Steel Short Radius Bends are the most widespread and utilize formulas to estimate the radius. Nevertheless, the actual radii may differ in practical applications.

A Guide to Producing Long Radius Bends

The Low Alloy Steel Welded Pipe Bend undergoes manufacturing through casting or bending within a die or roller setup, with cold drawing necessary for smaller diameter pipes. Conversely, High Alloy Steel Short Radius Bends can be cold-formed, while longer radius bends typically involve a process with a mandrel, preheating, and rolling over rotary draws.
