The invention relates to a composite type plastic pipe with wound netting wires and strengthened bell mouths, and a manufacturing process thereof. The invention adopts the following technical scheme: the tube ball with a distance of the inner diameter length L to the end part of the bell mouth is a reinforced and thickened wall; the tube wall with a distance of the outer diameter length M to the end part of the bell mouth is a netting wire reinforced wall; and a viscose glue layer, a mark and a protection layer, the wall thickness S, diameter phi and outer diameter D are set according to corresponding ratios; plastic resin mulling-ingredient is utilized as the raw material; and simultaneously, products are manufactured under the synchronous control of a dryer, an extruder, a die head, a die, a vacuum box, a spraying box, a take-up winder, a high-frequency machine, a tractor, a cutter and the like. The technical scheme of the invention overcomes the defect that the axial rigidity of the existing pipe workpiece influences the axial flexibility, geology sinking resistance and tension resistance at the welding part of the bell mouth, as well as the defect that the non-roundness at thejoint of the bell mouth leads the strength and rigidity at the cross section of the joint of the bell mouth of the pipe workpiece to be unable to load tubing pressure when the electrofusion pipe fittings are welded, and the like, thus being suitable for serving as connection pipe workpieces for various water delivery and gas transmission projects, and especially suitable for strengthening pipe walls and thickening the bell mouths of PE, PVC-U, PVC-M and the like.
