    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...                            了解更多

    Precautions for installation of plastic corrugated pipe

      Plastic bellows is the main compensating element of the expansion joint. In addition to displacement and deformation during installation and operation, it also bears a certain amount of pressure. In order to ensure the correct installation of the compensator, the following points must be noted:   ...                            了解更多
