Product basic introduction hdpe double-wall corrugated pipe (also known as high-density polyethylene double-wall corrugated pipe), made of high-density polyethylene as raw material, adopts double-wall structure design: the inner wall is smooth to reduce water flow resistance, and the outer wall is corrugated to enhance compressive performance. The product has good flexibility, can adapt to soil settlement, light weight, convenient transportation and installation, acid and alkali corrosion resistance, is suitable for a variety of environments, and has a long service life. The specification model covers the mainstream specifications of DN200-DN1200. The ring stiffness is divided into SN4 and SN8 grades to meet the pressure requirements of different projects. It adopts socket-type elastic sealing ring connection, which is reliable in sealing and suitable for various construction scenarios. Support manufacturers to customize in batches, and wholesale purchases can enjoy price discounts. Corresponding caliber products can be provided according to engineering needs. Product usage scenario Municipal drainage: suitable for urban rainwater and sewage pipe network laying, suitable for road and community underground engineering; Agricultural irrigation: used for farmland water conservancy and water transmission system, sediment resistance initialized, high installation efficiency; Industrial sewage: can transport general industrial wastewater, corrosion resistance is adapted to the factory environment; Cable protection: As an underground cable casing, it has both insulation and impact resistance. Manufacturers wholesale support to provide a full range of products for direct supply, bulk procurement process is convenient, and supporting pipe fittings are complete. Professional team can provide selection and installation guidance to reduce comprehensive construction costs.
