  • Fabric Smoke and Air Flue Duct Expansion joints

    Fabric Smoke and Air Flue Duct Expansion joints

    For non metallic expansion joints, our company (Shandong Hesper Rubber Plastic Co., Ltd.) have fabric expansion joints and rubber expansion joints(rubber soft joints). Fabric expansion joints can compensate the axial, transverse and angular displacement of the pipeline. It has the characteristics of no thrust, simplified support design, corrosion resistance, high temperature resistance, noise elimination and vibration reduction. It is especially suitable for hot air pipeline and smoke pipeline.

  • Stainless Steel Metallic Bellows Corrugated Expansion Joints

    Stainless Steel Metallic Bellows Corrugated Expansion Joints

    Metal Expansion Joints also called metal corrugated compensator, it composed by metal bellows and accessories such as end pipe, support, flange and conduit. Metal expansion joints can be used to absorb the dimensional changes of pipelines, conduits and containers caused by thermal expansion and cold contraction, or to compensate the axial, transverse and angular displacement of pipelines, conduits and containers. It also can be used for noise reduction and vibration reduction.
