| titleOfInvention | A kind of preparation method of large-caliber abrasion-resistant corrosion-resistant ternary composite pipe |
| abstract | The present invention relates to a kind of preparation method of large-caliber abrasion-resistant corrosion-resistant ternary composite pipe.The three-element composite piping inside nominal diameter DN is concretely comprised the following steps in 600mm~1200mm：1st, supporting wedge ring formula fixture or socket wedge ring type fixture are used on centrifuge, centrifugal rotation is carried out to large-diameter steel pipe；2nd, self propagating high temperature centrifugation synthetic reaction is carried out（SHS）, make reaction product TiB 2 /ZrB 2 ‑Al 2 O 3 Effectively it is distributed in steel pipe internal-surface；3rd, inner surface blended resins moulding by casting is carried out using centrifugal vacuum impregnation technology.The present invention makes wear-and corrosion-resistant tri compound layer using supporting die apparatus in steel pipe internal-surface, solves self propagating high temperature centrifugation synthetic technology（SHS）The problem that making applied to large-diameter pipe is present.The large-caliber abrasion-resistant corrosion-resistant ternary composite pipe made using the present invention, liner composite bed and outer layer pipe interface binding power are strong, mechanical shock resistance is high, different medium is effectively solved because thermal expansion different composite layer produces cracking and the phenomenon come off, wear-resistant corrosion resistance and good, service life is long, with important construction value. |
