IFB double wall power bellows

IFB inner-wall power bellows, also known as CM composite reinforced double-wall power bellows, has a novel structure design, unique structure, low friction resistance, good flexibility, high temperature resistance, high ring stiffness, and is not easy to break and age. The outer wall is a hollow ring structure, making full use of the I-steel structure principle to improve the rectangular inertia of the cross section, and the inner wall is very smooth, which improves the efficiency of threading. The products are widely used in excavation power engineering, and can replace HFB single-wall corrugated pipes, C-PVC power pipes, PVC-U communication pipes, glass steel pipes and other pipes. The normal service life of the pipe is more than 50 years.
