Get The Perfect Custom Tube Bending For Your Project

Whether you are working on a plumbing project or getting ready to manufactures a complex system, getting the perfect custom tube bending is essential to the success of your endeavor. With so many different tube bending companies out there, it can be difficult to know where to start.

The first step is to determine what type of tube bending you need. There are three main types of tube bending: precision tube bending, custom tube bending, and production tube bending (or fabricated tube assemblies). Each type has its own advantages and disadvantages, so it is important to choose the one that is best suited for your project.

Once you have selected the type of tube bending you need, the next step is to find the right company to the engineering support and services you require.

You can also get quotes from multiple companies before making your final decision. By taking the time to do your research, you can be sure to find the perfect custom tube bending for your project. At Precision Bending Technology, we know that our company’s experience, reputation, and price make us a great candidate.

Custom Bending Methods

Custom tube bending is the process of bending a tube to a specific shape. This can be done using a variety of methods, including:

  • Roll bending uses a series of rollers to bend the tube. The rollers are shaped to the desired shape of the tube, and the tube is passed through the rollers until it is bent to the desired shape.
  • Rotary draw bending uses a mandrel and a die to bend the tube. The mandrel is inserted inside the tube, and the die is placed on the outside of the tube. The tube is then drawn around the die, which bends the tube to the desired shape.
  • Induction bending uses a magnetic field to bend the tube. The tube is placed in a magnetic field, and the field is then used to bend the tube to the desired shape.

Depending on what shape you need, different types of bending will be used. The type is often dictated by the material of the tube, the desired shape of the tube, and the desired tolerances.

Here are some of the factors that go into custom tube bending:

  • Tubing material: The material of the tube will affect the type of bending process that can be used, as well as the final shape of the tube. For example, steel tubes can be bent using a variety of methods, while aluminum tubes are typically bent using rotary draw bending.
  • Desired Shape: The desired end shape of the tube will also affect the type of bending process that can be used. For example, a simple U-bend can be made using a variety of methods, while a complex shape may require a more specialized bending process.
  • Needed tolerances: The desired tolerances will affect the type of bending process that can be used, as well as the cost of the project. For example, a project with tight tolerances will require a more specialized bending process and will be more expensive.

If you are considering custom tube bending, you can talk with our team of designers and engineers to make sure you have the right process and materials to meet your specifications.

Material grain size matters in sheet metal bending Grain Size Image – (C) The Fabricator 8 ways material grain size affects how metal parts form

The Fabricator recently ventured to put together a comprehensive list on the ways that material grain size can affect the process of metal forming.

Eight Factors

During forming, sheet metal expands on the outside of the bend and compresses on the inside of the bend. How well the metal responds to the expansion and compression during bending determines the amount of unexpected deformation.

There are eight main factors that affect deformation during sheet metal forming related to material grain. A deeper understanding of these factors allows manufacturers to make corrective action that reduce variations during a part run. Analysis and insight into these eight factors, operators should see errors diminish and product quality improve.

The eight factors identified by The Fabricator article include:

1. Work Hardening. Plastic deformation causes dislocations within the metal’s structure, which in turn generates additional dislocations. 

2. Hardness Variation. Steelmakers make sheet metal within a tolerance zone for hardness. 

3. Thickness Variation. The same thing goes for material thickness, specified within a tolerance zone that corresponds to a given material gauge.

4. Bend Line Location. A feature near a bend changes the way that the metal expands, compresses, and deforms. 

5. Forming Method. The common bending methods on the press brake are air forming (or air bending), bottoming (or bottom bending), and coining.

6. Bend Length. The length of the bend is proportional to the tonnage required to make the bend. 

7. Grain Direction. During the process of turning ingots of metal into sheet at the mill, the metal is forced between a set of rollers. 

8. Grain Size. Grain within the material influences its strength. The borders between grains act like a barrier to dislocation movement. 

Further details about these eight factors and information on identifying grain is available in the full article available on The Fabricator: https://www.thefabricator.com/thefabricator/article/bending/grain-size-part-i-material-grain-size-matters-in-sheet-metal-bending

Reducing emissions and finding ways to produce energy more cleanly has been a priority for manufacturers for years. As the Environmental Protection Agency (EPA) regularly updates requirements to improve the safety and purity of emissions from engines, companies have been scrambling to keep up without sacrificing efficiency.

The latest Tier 4 Final emissions standards apply to both on-road and non-road engines – so many more manufacturers are now impacted by the rules, not just those associated with locomotive equipment like trucks and trains. Now, engines found in power generators and other stationary equipment will be under scrutiny as well. This especially impacts companies working in the oil and gas sector.

The main purpose of Tier 4 Final regulations is to cut back on the amount of particulate matter (PM) by 80% and nitrogen oxides (NOx) by 45% more than previous regulations. To meet this requirement, companies such as Cummins have already taken steps by implementing a selective catalytic reduction (SCR) after-treatment solution for engines. There’s a long line of chemical reactions that go on during this process, and in the end, ammonia and water vapor create the catalytic reaction that results in the reduction of NOx into a harmless gas. Full details on the chain reaction can be found on EngineerLive.

We’ve been working with companies to ensure that our tubes meet their requirements for Tier 4 Final standards. This requires the use of Stainless Steel materials and sufficient insulation on the outside of the tube to keep the gases inside hot (extreme heat is an essential component of the catalytic reaction). The number and severity of bends in a tube can impact heat loss, so we make a conscious effort to reduce the number of bends and ensure smooth transitions to retain the most heat possible.

Tier 4 Standards

We have already discussed the EPA’s new emission standards, which dictate that manufacturers must product engines that help  control exhaust emissions. We are now in the final stage of the requirement, Tier 4 Final Standards, which mandates that all  diesel engines that are put into service from 2015 and beyond must adhere to the EPA’s requirements.  Engines must now run  clean and tubes will need to be insulated to work properly. Tier 4 Final affects a variety of industries as diesel engines are used  in trucking, agriculture, road equipment, and more.

In the 1970s, manufacturers put catalytic converters in cars, which reduce unburned hydrocarbons through a catalytic reaction to water and CO2. In order for this process to work the exhaust gases must be kept at high temperature to enable the catalytic reaction.

To help engine manufacturers meet Tier 4 Final standards, Precision Bending now offers insulated Tier 4 Final tubes. The insulation helps ensure that the exhaust is kept hot as it moves through the tractor tubes.

As before, all of our Tier 4 tubes are cleaned to meet the engine manufacturer’s requirements and are packaged in a heat sealed bag to ensure our customers receive a perfectly clean tube.

Reducing emissions and finding ways to produce energy more cleanly has been a priority for manufacturers for years.

Rotary Draw Bending vs. Compression Bending

When it comes to tube bending services there are several methods, including compression bending and rotary draw bending. We’d like to talk a bit about each of these methods and uses for each.

Compression bending is a rather simple method that is often used on construction sites for bending electrical conduit. However, this type of bending is limited as it can’t make tight (small radius) bends because the pipe will buckle or break.

Rotary draw bending on the other hand allows for more control during the tube bending process as you use mandrels and dies inside the tube. This control allows us to make a very tight bend and can be used to make small dimensional tolerances. Additional benefits of this method include a smooth, aesthetically pleasing appearance which makes it an ideal for applications in which bend cosmetics are important. Rotary draw bending can also be used to bend square and rectangular tube and pipe, channel and extruded shapes.
