Abstract:

A method of sealing the interstice in double-walled pipe includes the steps of applying a first sealing piece to an inner pipe of the double-walled pipe, wherein the first sealing piece covers a portion of the circumference of the inner pipe; and applying a second sealing piece to the inner pipe of the double-walled pipe, wherein the second sealing piece covers the remainder of the circumference of the inner pipe. The method further includes the step of attaching the first sealing piece to the second sealing piece forming a sealer; wherein the sealer is disposed in an annular space located between the inner pipe and an outer pipe. A sealer configured to seal an opening between pipes in a double-walled pipe includes a first sealing piece having a rounded cross-section with an attachment portion configured to engage a corresponding attachment portion disposed on a second sealing piece.
