There are significant differences between wound pipes and bellows in many respects, and the following is a detailed summary of the differences between the two:

    1. Different manufacturing processes

• wound tube: After composite molding and secondary winding, it is made. This manufacturing process makes the wound tube have strong resistance performance.

• Bellows: It is extruded by machinery and equipment, and there is a cavity in the wall of the pipe. This manufacturing process is relatively simple, but may be slightly less strong than a wound tube.

    2. Different appearance

• wound tube: The shape is similar to a spring, and the inside is formed with propeller-shaped winding threads, which have certain geometric structural characteristics.

• Bellows: The appearance presents a rounded grain, basically a round shape, the tube wall is thin, and it has the characteristics of elastic sensitive elements.

    3. Different prices

• Because of the difference in manufacturing process and cost,wound tubePrice Pass constant ratioBellowsMake it higher.

    4. Different performance and use

• wound tube: Because of its unique manufacturing process, it has strong resistance and elasticity, and is widely used in electrical industry, machinery manufacturing, automobile parts, medical devices and building decoration and other fields. In the construction world, it is often used as the support and fixing of drainage pipes, which can solve the blockage problem and reduce the later drainage cost.

• Bellows: It is mainly used in instruments and meters as a measuring element of pressure measuring instruments to convert pressure into displacement or force. Its tube walls are thinner and sensitive, but the response rate may be slower than other types of measuring elements. In addition, bellows are also commonly used in situations where elastic sealing and displacement compensation are required.

    5. Different construction requirements

• wound tube: Because of its large requirements on the surface, it is necessary to ensure the stability of the foundation when using it.

• Bellows: It is relatively flexible and can be used in construction environments with slightly lower load-bearing capacity, such as residential drainage.

In summary, there are significant differences between wound pipe and bellows in manufacturing process, appearance, price, performance and use, and construction requirements. When choosing to use, it should be comprehensively considered according to specific application scenarios and needs.
