US Patent:

53723880, Dec 13, 1994

Filed:

Apr 30, 1993

Appl. No.:

8/056290

Inventors:

Joseph L. Gargiulo - Colts Neck NJ

Assignee:

American Pipe & Plastics, Inc. - Binghamton NY

International Classification:

F10L 5500

US Classification:

285 24

Abstract:

An integral conduit section of a multiple conduit system includes an outer housing having a straight coupling portion at one end and a belled coupling portion at the other end, a plurality of innerducts disposed in a parallel manner within the outer housing, one or more spacers for parallely positioning said innerducts in the outer housing, and a three-piece innerduct coupler disposed within the belled portion of the outer housing and engaged with the trailing ends of a plurality of innerducts, being linearly interconnectable with like conduit sections. The innerduct coupler includes a guide for facilitating entry of the plurality of innerducts of an adjacent conduit section into a like section; a seal that creates an air and water tight seal between the adjacent innerducts when like sections are interconnected, without the need for cement or sealing lubricants; and a seating component that terminally positions the innerducts in the innerduct coupler upon the interconnection of like integral conduit sections.

International Classification:

B29C 6334

US Classification:

425 59

Abstract:

A process for installing a liner in a generally horizontal pipe section includes the steps of: providing a hollow generally cylindrical folded pipe liner having a reduced cross section sized to allow the liner to be slidably drawn into the pipe section from an upstream end to a downstream end; pulling the folded liner through the pipe section leaving end sections of the liner extending from the upstream end and the downstream end of the pipe; snaking a pull wire through the liner; pulling an air hose and a steam hose through the folded liner from the downstream end to the upstream end; providing a floating plug assembly including at least two disk shaped expanders; attaching the steam hose to the floating plug assembly downstream of the disk shaped expanders; attaching the air hose to the floating plug assembly upstream of the disk shaped expanders; inserting the floating plug assembly into the liner at the upstream end; and providing steam to the steam hose and cooling air to the air hose, while pulling the floating plug assembly through the liner to progressively heat the liner to a softening point downstream of the disk shaped expanders, and expand the liner to fill the pipe and cool the expanding liner upstream of the disk shaped expanders.

Appl. No.:

Inventors:

Joseph L. Gargiulo - Colts Neck NJ

Assignee:

American Pipe & Plastics, Inc. - Binghamton NY

International Classification:

B29C 6334

US Classification:

264 403

Abstract:

A method for installing a pipe liner in a pipe includes the steps of reducing the diameter of the liner, so that it can be positioned within the pipe, installing the liner in the pipe, enlarging an upstream end of the liner, disposing a liner expander within the upstream end of the liner, pressurizing the upstream end of the liner with a heated fluid, the temperature of the heated fluid being sufficient to soften the liner, and the pressure of the heated fluid being sufficient to propel the liner expander from the upstream end of the liner to a downstream end, allowing a portion of the heated fluid to bypass the liner expander for heating and softening the liner ahead of the expander, and reducing the temperature of the pressurizing fluid to cool the liner below the softening temperature, to allow it to stiffen and form a liner within the pipe.

International Classification:

F16L 55165

US Classification:

138 98

Abstract:

A polymeric pipe lining composition consisting of 100 parts by weight of polyvinyl chloride, 0. 5 to 3. 5 parts of stabilizer, 5 to 30 parts of plasticizer, 0. 4 to 2. 0 parts of internal lubricant or wax, and 0. 4 to 2. 0 parts of external lubricant or wax. The composition is especially useful for in situ lining of sewers.
