NOVELTY - A strong corrosion resistance steel belt reinforced spiral corrugated pipe comprises outer pipe and an inner pipe. A steel belt is arranged between the outer pipe and the inner pipe and runs along the outer pipe and the inner pipe. The outer tube and inner tube are composed of 80-120 pts. wt. bisphenol A epoxy vinyl resin, 30-60 pts. wt. phenolic resin, 20-34 pts. wt. polypropylene, 34-42 pts. wt. glass fiber, 6-12 pts. wt. modified graphene, 3-7 pts. wt. silicon carbide powder, 5-10 pts. wt. color masterbatch, 2-12 pts. wt. coupling agent, 20-40 pts. wt. carboxyl nitrile rubber, 1-2 pts. wt. anti-embrittle agent palmitic acid, and 0.5-1.5 pts. wt. anti-fungal agent. USE - Strong corrosion resistance steel belt reinforced spiral corrugated pipe. ADVANTAGE - The corrugated pipe has strong corrosion resistance, effectively improves the problem of bad heat resistance, and greatly improves the heat conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparation of corrugated pipe comprising heating steel strip to 200-300degreesC, heat preserving, melting adhesive, coating on the surface of the heated steel strip, cooling the steel strip, pulling, and processing into a wave structure; weighing glass fiber, modified graphene, silicon carbide powder, bisphenol A epoxy vinyl resin, phenolic resin and polypropylene, mixing, and melting at 190-230degreesC; combining remaining raw materials, mixing, and melting at 190-230degreesC; mixing mixed plastic solutions, banburying at 150-190degreesC for 30-40 minutes, mixing, cooling to 20-30degreesC, and discharging; extruding and granulating at 160-180degreesC and drying; and putting into forming machine, pulling, cooling, and shaping.
