Our factory is equipped with professional circular sewing machines, which boast aesthetically pleasing appearances, flat interiors, and fine craftsmanship, with a lifespan capable of over a million uses. Thanks to the reinforced wire frame, they are flexible, resistant to deformation, and wear-resistant. Made with durable industrial canvas, they offer high cost-performance and have received positive feedback from numerous customers. They feature compact structures, ease of use, high distribution efficiency, and dust-free loading and unloading. They are not only used for the automated or semi-automated unloading of cement storage for cars, trains, and ships but also for the bulk distribution of materials like coal powder, stone powder, aluminum powder, and food powders.

Flexible expansion joints can be used horizontally or vertically. When used horizontally, they are typically made with a support ring process, ensuring a uniform distance between the sheath inner cavity and the cylinder, reducing friction and extending service life. For larger stretch lengths, a metal ring can be added at each bend to enhance the stability of the sheath. Installation methods are unrestricted; they can be fixed with a flange or with a collar band.
