Description
About this product
The Inversion Dry Felt Tube is a fiber-reinforced or braided hose equipped with an impermeable membrane, designed to be impregnated with a thermosetting resin and inverted into the host pipeline using air or water pressure.
Once inverted, the flexible liner is cured with hot water or steam, forming a rigid lining that adheres tightly to the inner wall of the original pipe. Prior to curing, the flexibility of the resin-impregnated hose enables it to fill cracks, bridge gaps, and navigate around curved sections.
Strict quality control is applied to raw materials, with production standards adhering to German technical specifications and ASTM standards. The laminated coating layer uses a specialized PE or PP formulation, ensuring a wrinkle-free finish, low friction coefficient, and ease of inversion — facilitating long-distance installation operations.
A unique stitching process ensures superior structural strength at seam joints. The sealing and welding of the laminated coating are executed using a fully automated thermal sealing process, guaranteeing zero leakage, cracking, or delamination.
