摘要：Pipes and other substrates exposed to or submerged in water can be protectedby coating them with a corrosion protection sealing material and subjecting the material
during or after it has been applied to the substrate to pressure applied progressively.The pressure is provided by progressive recovery of a sleeve as it is released from aholdout which holds it in a recoverable configuration. The progressive recovery can be,for example, from one end of the sleeve to the other or from the center of the sleeveoutwards to each end. The progressive shrinkage can be achieved, for example, by use ofan external holdout which releases an inner expanded sleeve when contacted withsolvent around the circumference of the sleeve commencing at one end of the sleeve andcontinuing along the sleeve to the other end.
