step seven: impregnating glass fiber roving with resin, and then, transversely and circularly paving the glass fiber roving along a longitudinal winding layer (8) to form an annular winding layer (9);
step eight: impregnating glass fiber roving with resin, and then crosswise winding the glass fiber roving on the surface of the annular winding layer (9) to form a crosswise winding layer (10);
step nine: carrying out far infrared deep curing treatment on the longitudinal winding layer (8), the annular winding layer (9) and the cross winding layer (10), forming a composite winding layer (4) by the longitudinal winding layer (8), the annular winding layer (9) and the cross winding layer (10), checking whether the composite winding layer (4) is qualified, continuing processing if the composite winding layer is qualified, and strictly prohibiting the processing on the machine if the composite winding layer is unqualified;
step ten: after being soaked by resin, the continuous glass fiber sheet is laid along the longitudinal direction of the composite winding layer (4) to form a stitch-bonding felt layer (11);
step eleven: coating the thin felt sheet outside the stitch-bonding felt layer (11) after being soaked by resin to form a surface felt layer (12);
step twelve: the wear-resistant powder is soaked in resin and bonded on the outer side of the surface felt layer (12) to form a wear-resistant layer (13);
step thirteen: far infrared deep curing treatment is carried out on the stitch-bonding felt layer (11), the surface felt layer (12) and the wear-resistant layer (13), and the stitch-bonding felt layer (11) and the surface felt layer (12) form a protective outer layer (5);
fourteen steps: the inner liner (3), the composite winding layer (4) and the protective outer layer (5) form a glass fiber reinforced plastic outer sleeve (2), the glass fiber reinforced plastic outer sleeve (2) and the metal tube core (1) are taken down from the equipment together, the glass fiber reinforced plastic outer sleeve (2) and the metal tube core (1) are cooled and shaped, and the glass fiber reinforced plastic outer sleeve (2) and the metal tube core (1) form an anti-corrosion tube.
