Development of technology for forming bilayer, resources preserving, corrugated plastic pipe products

The process of forming the corrugation with different geometrical parameters is investigated. The analysis of the indicators formability and the ability of polymeric material for welding is executed. The dependence of the wall thickness of the corrugated pipe for sloping walls, for vertical walls, for high and low profile, for different shapes set at different angles of the walls forms, for different width and height corrugation, for different sizes of products is determined. The technology of forming a two-layer corrugated tube of thermoplastic material is developed.
