Single-wall Plastic Corrugated Pipes
Single-wall bellows: PVC is the main raw material, which is made by extrusion blow molding. It is a product developed in 1970s. The inner and outer surfaces of the single-wall corrugated pipe are corrugated.Since the hole of the plastic corrugated pipe product is in the trough and is elongated, it effectively overcomes the drawbacks of flat-walled perforated products that are easy to be blocked and affect the drainage effect. The structure is reasonable, so that the pipe has sufficient compressive and impact resistance.
