What's the difference between a single wall bellows and a double wall bellows
Many similar products different from the name we just can make a general judgment, such as single wall corrugated pipe with different double wall corrugated pipe, a single double, we can know the simple single and double performance is external, specific distinction we look down. GHFB square type high voltage power cable protects single wall bellows.
1, the type of tube wall is different: single wall corrugated pipe, both inside and outside of the tube wall are corrugated plastic pipes; double wall corrugated pipe is a new tube with ring structure outer wall and smooth inner wall.
2, PVC single wall corrugated tube is made of PVC as the main raw material, by extrusion blow molding. The PVC single wall bellows can use both the structure of the annular groove and the rigidity of the rigid PVC pipe and the flexibility of the hose. Therefore, the pipe has the characteristics of rigidity and flexibility, and it can be used to transport some liquids and gases as well as the bushing for buried wires. GHFB square type high voltage power cable protects single wall bellows.
3, single wall bellows are basic structural parameters with inner diameter or outer diameter, and other such as wall thickness, wave distance and wave thickness are determined with inner diameter or outer diameter as the reference. The ripple height can be expressed by the wave depth coefficient K, which is the ratio of the outer diameter to the inner diameter of the bellows. The greater the value, the higher the height of the ripple. The waveform of the corrugated pipe can be divided into spiral shape, U shape, C shape, S shape, V shape and Omega shape according to the axial cutting. The waveform has certain influence on the stiffness and strength of the tube. Single wall bellows are cheap, because only one layer is easy to damage, and double arm bellows are not easy to damage because of one more layer.
So we first need to take a look at the environment around us, and see what kind of pipes are suitable for our environment. Whether we are double wall corrugated pipes or single wall ones, we need to figure out what we can do better. GHFB square type high voltage power cable protects single wall bellows.
