Abstract
The present invention provides leakage plugging devices and methods for sealing a leakage at a remote site in a pipe, the device including a porous carrier plug of a deformable material including pores and at least one sealant composition disposed in the pores, wherein the porous carrier plug is adapted to transport the at least one sealant composition from a first site to a remote site and to plug the leakage at the remote site.
Claims21
A leakage plugging device for sealing a leakage at a remote site in a pipe, the device comprising:
- a. a porous carrier plug of a deformable material comprising pores carrying a first density enhancing dried composition;
- and
- b. at least one sealant composition disposed in said pores, said at least one sealant composition comprising at least one filler, a premixed hardening agent, at least one surfactant, and at least one resinous agent, wherein said porous carrier plug is adapted to transport said at least one sealant composition from a first site to a remote site and to plug said leakage at said remote site.
A leakage plugging device according to claim 5, wherein said first dimension is in a range of 2 mm to 15 mm.
