Steel pipe composite pipes are divided into three layers: the inner layer is a polyethylene material called the core tube; the middle layer is a steel wire mesh, formed by wrapping high-strength copper wires to create a skeletal structure, primarily used for bearing pressure; the outer layer is also polyethylene plastic, predominantly black. Each layer must be bonded together with a special adhesive to prevent delamination between layers.
