Patent number: 10663101Abstract: A method is shown for installing a heat tube on a section of pre-insulated piping. A metal carrier pipe is covered with a first layer of foam insulation. Next, a routing device is used to cut a longitudinal slot along the length of the pipe so that the pipe exterior surface is exposed from the insulation. A heat tube is then installed within the longitudinal slot, whereby the heat tube contacts the exterior surface of the metal carrier pipe. A second layer of foam insulation is then sprayed onto the exterior of the metal carrier pipe, covering the previously formed longitudinal slot and installed heat tube. A polyolefin coating is then applied over the insulation to form a protective outer jacket for the insulated pipe.Type: GrantFiled: April 12, 2019Date of Patent: May 26, 2020Assignee: Thermacor Process, Inc.Inventors: Thomas Joseph Keyes, Clinton James Riggin

Patent number: 10293527Abstract: A method for the continuous production of pre-insulated piping having an inner metal carrier pipe having an interior surface and an exterior surface and an envelope of foamed insulation surrounding the inner metal carrier pipe exterior surface. A molding apparatus is provided for forming an annulus about a pipe to be insulated into which foam can be injected. The pipe is continuously moved through the apparatus with foaming material being injected into the annulus where it is molded and cured to form a foam insulated pipe. The molding apparatus is a roller-drum having a cylindrical length and a plurality of individual rollers arranged in a series of linearly staggered, circular arrays which define the annulus where the foaming material is cured.Type: GrantFiled: December 2, 2016Date of Patent: May 21, 2019Assignee: Thermacor Process, Inc.Inventor: Thomas Joseph Keyes

Patent number: 9140386Abstract: An anchor system is shown for use with a pre-insulated piping system having an inner steel carrier pipe surrounded by a layer of insulation and then by an outer protective jacket. The anchor system includes an inner carrier pipe for insertion within the length of the piping system at a selected point. A steel anchor sleeve surrounds a portion of the length of carrier pipe and insulation. It terminates at one end at an outwardly flaring anchor plate which is subsequently embedded within a concrete anchor block. A steel end cap is welded to a second, opposite end of the sleeve and to the inner carrier pipe at a point along the length of piping which is outside the concrete anchor block and which is spaced apart from the location of the anchor plate, whereby heat from the high temperature fluids in the piping is transferred to the end cap at a location along the length of piping which is distant from the location of the anchor plate.Type: GrantFiled: August 29, 2013Date of Patent: September 22, 2015Assignee: Thermacor Process, Inc.Inventor: Thomas Joseph Keyes

Publication number: 20120146324Abstract: An expansion joint is shown for an insulated pipeline used to convey high temperature fluids such as steam. The expansion joint uses a flexible bellows and additional insulating and joining components to provide a watertight encasement for a traditional metal expansion joint. The bellows arrangement compensates for any relative movement of the inner fluid conveying pipes with respect to the outer layers of insulating material and outer jacket in order to protect the integrity of the assembly and prevent the intrusion of water or other contaminants which could lead to corrosion or early failure of the piping system.Type: ApplicationFiled: January 24, 2011Publication date: June 14, 2012Applicant: Thermacor Process, LPInventor: Thomas Joseph Keyes

Publication number: 20120118388Abstract: A system is shown which can replace the need for a traditional watertight manhole servicing a pre-insulated pipeline. The piping in the system is pre-insulated, as with a bonded foam insulation. The valves and fittings in the piping system are brought to a convenient height above the watertable in an excavated area in the surrounding earthen formation and are also pre-insulated. The pre-insulated valves and fittings are partially enclosed by a containment structure which keeps the surrounding earthen formation in place. Because the valves, fittings and piping are pre-insulated, it is not necessary to maintain the surrounding enclosure in a watertight condition as was the case with a traditional manhole.Type: ApplicationFiled: November 7, 2011Publication date: May 17, 2012Inventor: Thomas Joseph Keyes

Patent number: 8033754Abstract: An installation technique is shown for use with a pre-insulated steam piping system having an inner steel carrier pipe surrounded by a layer of foam insulation and then by an outer protective jacket. An expansion loop is used to create an artificial low point in the overall pipeline which allows the pipeline to avoid a buried obstruction without the necessity of increasing the depth of the remaining portion of the pipeline on either side of the loop. The expansion loop has a pair of oppositely arranged side legs which are joined by a cross-leg portion of the loop, the cross-leg portion of the loop being angled downwardly at a predetermined angle, to thereby provide a change in elevation which avoids the buried obstruction in the pathway of the pipeline.Type: GrantFiled: August 19, 2009Date of Patent: October 11, 2011Assignee: Thermacor Process, L.P.Inventor: Thomas Joseph Keyes

The length of piping has a joining end for joining to an adjacent length of piping, whereby the adjacent lengths of piping provide a continuous length of fluid conduit for conveying high temperature fluids. A water containment element is located on the exterior of the inner carrier pipe at a location near the pipe joining end. The containment element serves to stop the flow of any intruding water or steam along the length of the inner carrier pipe. The containment element may also include a heat dissipating element which surrounds the inner carrier pipe for at least a portion of the length thereof.Type: ApplicationFiled: April 28, 2010Publication date: August 11, 2011Inventor: Thomas Joseph Keyes
