    What is the difference between pe pipe and bellows?

    There are two common plastics: one is polyethylene film; the other is polyvinyl chloride film. The plastic bag made of polyethylene film is non-toxic and can be used to hold food, but its strength is not good. And can not withstand high temperatures above 80 ℃, and has a certain permeability, not su...                            了解更多

    How to choose the material of plastic bellows

    According to foreign standards, the material of plastic bellows is usually made of high-density polyethylene plastic (PE) and polypropylene plastic (PP). High-density polyethylene plastics are basically used in China. The difference between the two materials is that polypropylene plastic (PP) materi...                            了解更多

  • Structural layering of plastic bellows

    Structural layering of plastic bellows

    Due to the low strength and elastic modulus of plastic itself, there is no adhesion between plastic and cement slurry and concrete, so there is an objective weak layer along the bellows interface in the structure. For structures with densely distributed linear prestressed beams at the same height of...                            了解更多
