Spiral corrugated pipe capable of enhancing connection tightness
Technical Field
The utility model relates to a helical bellows for enhancing connection tightness.
Background
With the rapid advancement of industry development and urban infrastructure construction, piping plays a critical role in the transport of liquids and gases. Spiral corrugated pipes are widely used in various fields such as municipal engineering, chemical industry, building water supply and drainage, etc. due to their unique corrugated shape, good flexibility and excellent pressure resistance. However, conventional screw bellows connections often present challenges such as insufficient tightness, difficult installation, poor environmental compatibility, and high maintenance costs. Therefore, aiming at the defects of the traditional spiral corrugated pipe connection technology, development of a new technology is imperative.
In the prior art, the connection of the spiral corrugated pipe usually adopts a rubber gasket, a clamp or welding method and the like to achieve the sealing effect. However, these methods have problems of being easy to age, poor in stability, cumbersome to install, high in long-term maintenance cost, and the like. In particular, in an environment where high temperature, high pressure or external vibration is frequent, the reliability of the conventional connection method is greatly reduced. In addition, in some applications requiring pollution-free transmission, leakage at the junction may result in serious environmental pollution and resource waste.
