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.

Pellet compositions for sealing a leak include (a) a fibrillated fibrous material, (b) a particulate material, and (c) a compound that by itself and/or in combination with at least one additional compound is configured to generate effervescence. Systems for sealing a leak include (a) a pellet composition, and (b) a first fluid configured for combination with the pellet composition, wherein the first fluid includes water. Methods for sealing a leak in a heat exchange system are described.

Methods and systems for cleaning, coating and sealing leaks in existing pipes, in a single operation. A piping system can be cleaned in one pass by dry particulates forced and pulled by air throughout the piping system by a generator and a vacuum. Pipes can be protected from water corrosion, erosion and electrolysis, extending the life of pipes such as copper, steel, lead, brass, cast iron piping and composite materials. Coatings can be applied to pipes having diameters up to approximately 6″. Leak sealants of at least approximately 4 mils thick can cover insides of pipes, and can include novel mixtures of fillers and epoxy materials, and viscosity levels. A positive pressure can be maintained within the pipes during applications. Piping systems can be returned to service within approximately 96 hours.

Provided is a liquid leakage repair material, including: a curable composition, wherein a liquid absorption rate of the liquid leakage repair material after cured is lower than 10%.
