Pipe bending operations are tricky. Rippling, for instance, is among the issues most people find hard to deal with. The good news is that these issues are avoidable. Researching on them and how to avoid them helps. What are the most common mistakes to avoid when bending pipes?
Using the Wrong Type of Machine
Pipe benders come in all shapes and sizes. Before choosing a Baileigh pipe bender, you should determine your tube bending requirements. The basic types of benders are manual, air, electric, and CNC electromechanical benders. If you have a large project, a manual bender wouldn’t be the right type of machine for you. Such a machine would also be unsuitable where repeatability and high precision are required.
Not Evaluating Your Materials
You can only bend appropriately if you know the properties of the materials you’d be bending. In addition to material type, you should consider thickness, outside diameter, and centerline radius. If you prefer compression bending, be careful to avoid rippling. Pipes with thin wall thicknesses wrinkle when there’s a high compressive force on the inside of bends. You should understand that different materials behave differently regarding spring-back. Some might require a bending of 95 degrees to achieve a 90-degree bend.
Proper lubrication is important for a high-quality bend because it reduces friction. You should choose lubrication in respect to the thickness of the materials to bend. Thicker materials require more lubrication. If diluting lubrication would be necessary, be careful to do so to the ideal consistency. Also, ensure that your machines are in excellent working condition.
If you’re new to tube bending, it’s best to seek guidance from knowledgeable and experienced technicians before you start bending. While learning on the job is an option, it would most likely mean damage to your machine and waste of time and materials.
