Many pipe factories are looking again at FRP winding equipment because labor cost and batch stability are becoming harder to balance. In our workshop, buyers often ask first about diameter range, carriage movement and daily maintenance, not only about the selling price. A pipe line using wet sand filling can work with Φ300 to Φ3000 mm products and an effective length around 12.5 m when the design is
matched correctly. This kind of equipment is useful for drainage pipe, water transport pipe and chemical pipe projects. Before shipment, we prefer to test the main movement, yarn guiding and resin related parts, then send the buyer clear photos and running videos. It is a plain step, but it avoids many small problems after installation. It also helps both sides confirm whether the machine fits the old workshop space.
