Detailed Explanation of Coil Processing Methods

1. Overview

Coil is a type of pipe widely used in cold and hot water air conditioning, refrigeration units, electronics, medical, aquaculture, and food industries. The coil needs to be processed before use to meet the needs of different occasions. There are many processing methods for coil tubes, and this article will introduce the commonly used methods and the precautions to be taken during the processing.

Bending coils is a very common machining method. By using a pipe bending machine, it is easy to bend the coil into a curved shape as needed. During the bending process, the following points need to be noted:

(1) The coil cannot be bent too much. Generally, the smaller the pipe diameter, the smaller the bending radius of the coil; On the contrary, the larger the pipe diameter, the larger the bending radius of the coil.

(2) The bending angle should gradually increase to avoid deformation or fracture of the coil.

(3) Before bending, cut and remove burrs from the coil.


Cutting is another commonly used method for coil processing. The use of a shearing machine can accurately cut the coil to the desired length. During the cutting process, the following points need to be noted:

(1) The cutting of the coil should be carried out on a flat shearing machine to ensure a smooth cut.

(2) The incision should be straight, without burrs or skewness, otherwise it will affect the use of the coil.

(3) Before cutting, measure the coil to ensure accurate cutting length.


Welding of coils is a method of connecting two coils together. The use of TIG welding can provide high-quality connections to coils, making them less prone to leakage during use. During the welding process, the following points need to be noted:

(1) Before welding the coil, it is necessary to clean the surface to remove oil stains, impurities, etc.

(2) During the welding process, appropriate pressure should be applied to the weld seam to ensure welding quality.

(3) When welding, attention should be paid to preventing excessive heating to avoid deformation or explosion of the coil.

3. Summary

Although coil processing may seem simple, many factors need to be considered in specific operations. This article introduces common methods for coil processing, hoping to help readers better complete coil processing tasks. In the actual processing process, it is necessary to flexibly apply these methods according to specific situations and pay attention to precautions to ensure processing quality.
