BONDING OF STEEL STRIPS IN STEEL STRIP LAMINATE PIPE

摘要

A STEEL STRIP LAMINATE PIPE HAVING INCREASED LAP SHEAR STRENGTH AND PEEL OFF STRENGTH BETWEEN THE STEEL LAYERS IN THE PIPE AND A METHOD FOR MAKING SUCH A STEEL STRIP PIPE ARE PROVIDED.STEEL STRIPS COATED WITH A SOL-GEL OR A SILANE ADHESION PROMOTER (16) ARE WOUND OVER AN INNER LINING (40) TO FORM STEEL LAYERS BONDED TO EACH OTHER IN A STEEL STRIP LAMINATE PIPE. IN AN ALTERNATE EMBODIMENT, FIBER FILLERS AND RESIN ARE USED TO BOND THE STEEL LAYERS IN THE PIPE TOGETHER. IN FURTHER EMBODIMENT, GLASS SPHERE AND RESIN ARE USED TO BOND THE STEEL LAYERS TOGETHER. THE STEEL STRIPS BONDED TOGETHER USING CONTINUOUS REINFORCED FIBER FILLER (46) OR GLASS SPHERES MAY BE COATED WITH SOL-GEL OR SILANE. IN AN ALTERNATE EMBODIMENT, THE SOL-GEL OR SILANE MAY ALSO BE MIXED IN THE RESIN USED TO BOND THE STEEL LAYERS TOGETHER.(FIG 1)
