How To Solve The Folding Problem That May Occur When PEX Tube Is Bent

Introduction：

PEX-AL-PEX pipes combine PEX's flexibility with an aluminum core for added strength and thermal stability, offering superior durability, corrosion resistance, and ease of installation for plumbing and heating systems.

To solve the folding problem that may occur when the PEX tube is bent, you can start from the following aspects:

Select the right PEX pipe

Adequate thickness: Choosing PEX tubing with adequate thickness is the key to reducing wrinkles. Thicker tubes are better able to resist deformation when bent, thus reducing the development of wrinkles. Therefore, when purchasing PEX pipes, pipes with sufficient thickness should be selected according to actual needs and the use environment.

Optimized bending process

• Appropriate bending radius: Ensure that the bending radius is appropriate to avoid excessive deformation of the pipe caused by too small a bending radius. Too small a bending radius will increase the stress on the inside of the pipe, making it easier to fold.
• Control bending speed: When bending PEX tubes, the bending speed should be controlled to avoid uneven force in the bending process caused by too fast or too slow. The proper bending speed is helpful to maintain the uniform force of the pipe and reduce the generation of folds.

Use AIDS

• Specialized bending dies or tools: Specialized bending dies or tools are used to assist in bending PEX tubes. These molds or tools can ensure that the pipe is stressed evenly during bending, thus effectively reducing the formation of wrinkles.
• Mandrel and wrinkle plate: During the bending process, mandrel can be added to support the inside of the tube to prevent the folding of the material. At the same time, the installation of anti-wrinkle panels can further inhibit the generation of wrinkles. The anti-wrinkle plate is like a scraper, and the wrinkles that may occur on the inside of the pipe during the bending process are scraped.

Repair wrinkles that have appeared

Heat treatment or pressure adjustment: For PEX tubes that have appeared wrinkled, you can try to repair them by heat treatment or pressure adjustment. For example, by heating the pipe to soften it, and then adjusting the bending Angle and force, the wrinkles can be eliminated. However, it should be noted that these methods may have some risks, and should be operated with caution and follow the relevant safety regulations.

Regular inspection and maintenance

Regular maintenance and inspection: Regular maintenance and inspection of PEX tubes is also very important. Through regular inspection, potential folding problems can be detected and resolved in time to ensure the normal operation of the pipeline system. At the same time, inspection can also help identify other potential points of failure, such as leaks, corrosion, etc., so that measures can be taken in advance to repair.

To sum up, it is necessary to select the appropriate pipe, optimize the bending process, use auxiliary tools and regular inspection and maintenance to solve the folding problem that may occur in the bending of PEX pipe. The integrated application of these measures can effectively reduce the risk of PEX pipe folding in the bending process, and ensure the stability and safety of the pipeline system.
