Product basic introduction PVCM double-wall corrugated pipe (also known as PVC double-wall corrugated pipe, PVCM corrugated pipe), made of PVCM as raw material, double-wall structure design: the inner wall is smooth to reduce water flow resistance, and the outer wall is corrugated to enhance compression resistance. The product is resistant to acid and alkali corrosion, has good flexibility, is light in weight, is easy to install, is suitable for a variety of environments, has a long service life and low comprehensive cost. Specification model covers DN200-DN800 commonly used specifications. The ring stiffness is divided into SN4 and SN8 grades to meet different engineering pressure requirements. It adopts socket-type elastic sealing ring connection, which is reliable in sealing and suitable for a variety of construction scenarios. Support manufacturers to customize in batches, and the wholesale purchase price is favorable. Corresponding caliber products can be provided according to engineering needs. Product usage scenario Municipal drainage: urban rainwater and sewage pipe network laying, suitable for road and community underground engineering; industrial sewage: factory wastewater, mildly corrosive liquid transportation, stable chemical resistance; agricultural irrigation: farmland water conservancy water transmission system, sediment resistance initialize, small flow loss; construction engineering: drainage around buildings, underground garage drainage, adapt to foundation settlement. Manufacturers wholesale support to provide a full range of direct supply of products, bulk procurement process is simple, complete supporting pipe fittings. Professional team can provide selection and installation guidance to reduce construction costs. Contact information: 13339996652, welcome to consult product quotation and procurement details.
