US Patent:

51679019, Dec 1, 1992

Filed:

Feb 25, 1992

Appl. No.:

7/840851

Inventors:

F. Thomas Driver - Memphis TN
Joseph A. Alexander - Memphis TN
Lloyd G. Buchanan - Collierville TN

International Classification:

B29C 6336

US Classification:

264570

Abstract:

In a tube eversion apparatus a first chamber in which the eversion pressure is developed is controllably sealed by a sphincter-type valve, the valve being in turn actuated by pressure developed in a preferably separately controllable and adjustable second chamber, another chamber preferably being provided above the sphincter-type valve for containing a supply of liquid and limiting turbulence from any escape of fluid past the sphincter-type valve, the other chamber also providing apparatus for supplying heated fluid to a lay-flat hose adapted to be pulled through the sphincter-type valve by the tube being exerted. Use of the improved apparatus involves appropriate modifications of the usual eversion process involving applying and controlling the everting pressure and the pressure exerted against the sphincter-type valve by the fluid in the second chamber.

Appl. No.:

8/789018

Inventors:

Joseph A. Alexander - Memphis TN

Assignee:

Insituform (Netherlands) B.V.

International Classification:

B29C 6336

US Classification:

264516

Abstract:

A compact apparatus for everting a liner utilizing fluid pressure after the liner has been aligned with the conduit to be lined is provided. The apparatus includes a sphincter valve with its axis aligned with the conduit to be lined and an eversion pressure chamber overlapping a portion of the sphincter valve for reducing the length of the apparatus and allowing positioning in a sewer manhole. A downtube is positioned at the input side of the sphincter valve which can extend to the top of the manhole. To install a liner, the apparatus is placed in the entrance manhole with the sphincter valve aligned with the axis of the sewer pipe, the liner is inserted into the downtube, turned to align with the sphincter valve and conduit and fluid pressure is applied to the valve to engage the flattened liner which after passing through the valve is everted by fluid pressure as it enters the sewer pipe.

Filed:

Appl. No.:

8/105220

Inventors:

Hernan R. Menendez - Millington TN
Douglas K. Chick - Elstree, Hertfordshire, GB2
Joseph Alexander - Memphis TX

International Classification:

B29C 6334

US Classification:

264 36

Abstract:

A method and apparatus for expanding a replacement thermoplastic pipe installed within an existing conduit is provided. A pipe expansion apparatus having a flexible substantially cylindrical bladder and a relief valve to inflate the bladder to a predetermined gauge pressure and allow fluid to exit the expansion apparatus and fill and pressurize the area behind the apparatus is inserted within the collapsed pipe. Fluid, such as cold water, is introduced into the apparatus to inflate the inflatable section to conform substantially to the interior diameter and configuration of the existing conduit. As the area behind the expander fills with pressurized fluid, the expansion apparatus is pushed forward, thereby pushing and expanding the replacement pipe up against the interior of the existing conduit. Steam is injected ahead of the apparatus to maintain the replacement pipe in a heated flexible condition. When the fluid introduced into the expander is cold water, the replacement pipe will cool and become rigid almost immediately after it is expanded and significantly reduce stress formation.
