Description

Technical field:

[0001] The invention relates to the design, manufacture and engineering connection of steel-plastic composite pipes and pipe fittings, to the design and engineering connection of steel skeleton reinforced composite polymer pipes and pipe fittings with holes, especially to the reinforced steel skeleton with holes Manufacture, design and connection of composite polymer pipe fittings for engineering applications. Background technique:

[0002] The perforated steel plate (belt) is curled into a cylindrical skeleton and welded to form a metal reinforcement in the steel-plastic composite pipe wall; and the latitudinal steel wire is wound with the warp steel wire and welded or the warp steel wire is spirally wound. Distributed and welded on the steel-plastic composite pipe wall to become the metal reinforcement in the steel-plastic composite pipe wall; and spirally wound or braided steel wire on the formed polymer pipe wall to form a cylindrical steel skeleton, and...
