Protective seal for pipeline assembly

A protective seal assembly for sealing at least one seal region of a pipeline assembly having an outer surface, the seal assembly comprising:

• a first wrap member wrapped around at least a portion of the at least one seal region and contacting the outer surface of the pipeline assembly, the first wrap member including a corrosion-resistant material;
• and
• a second wrap member wrapped around and circumscribing the first wrap member, the second wrap member including a self-adhering, fiberglass composite material,
• wherein the corrosion-resistant material of the first wrap member comprises a self-adhering polymer, and the self-adhering polymer is a viscoelastic polyisobutene.

A protective seal assembly for sealing at least one seal region of a pipeline assembly having an outer surface, the seal assembly comprising:

• a first wrap member wrapped around at least a portion of the at least one seal region and contacting the outer surface of the pipeline assembly, the first wrap member including a corrosion-resistant material;
• and
• a second wrap member wrapped around and circumscribing the first wrap member, the second wrap member including a self-adhering, fiberglass composite material,
• wherein the second wrap member exhibits an abrasion resistance of approximately 2.0 mils/second.

A protective seal kit for sealing at least one joint region between first and second pipes each having an outer surface, the protective seal kit comprising:

• a first flexible wrap configured to wrap around at least a portion of the outer surfaces of the first and second pipes and to substantially surround the at least one joint region, the first flexible wrap being at least partially fabricated from a corrosion-resistant material;
• and
• a second flexible wrap configured to wrap around at least a portion of the outer surfaces of the first and second pipes and to substantially surround the joint region and the first flexible wrap, the second flexible wrap being at least partially fabricated from a fiberglass cloth impregnated with a resinous pliable-plastic material configured to harden upon exposure to aqueous moisture,
• wherein the second flexible wrap, when hardened, exhibits a tensile strength of approximately 20,000 to 39,500 psi and an impact resistance of approximately 80 to 300 joules.

A method for sealing at least one joint region between at least first and second pipes each having an outer surface, the method comprising:

• wrapping a flexible corrosion-resistant inner wrap around at least a portion of the first and second pipes such that the inner wrap substantially surrounds the joint region and adheres to the outer surfaces of the first and second pipes;
• wrapping a flexible fiberglass-composite outer wrap around the inner wrap and at least a portion of the first and second pipes such that the outer wrap substantially surrounds the inner wrap and adheres to the outer surfaces of the first and second pipes;
• and
• curing the flexible fiberglass-composite outer wrap such that the outer wrap exhibits a tensile strength of approximately 20,000 to 39,500 psi and an impact resistance of approximately 80 to 300 joules.
