Publication number: 20200263822Abstract: A service reinforcement sleeve is disclosed with a flange and a tubular section that can be used, with epoxy, to bind a service to a structural liner such as a cured-in-pipe structural liner. This sleeve has flexible tabs with lips (defined by cutouts) on the end of the tubular section opposite the flange. This sleeve can accommodate encrustation in the service, particularly when it is located away from the bottom of the service. A method of bonding a service and structural liner using this sleeve and epoxy is also disclosed that uses a metal brush or similar device to create a seat in the liner and abrade the lower portion of the service before insertion of the sleeve.Type: ApplicationFiled: February 15, 2019Publication date: August 20, 2020Inventors: Kendrick Shaun MCKAIGUE, Vadim KOSSENIOUK

Publication number: 20200263825Abstract: A method of minimizing material mixing in a piping system during a transition between a first material and a second material includes providing a plurality of pipe pigs in a first pipe section with the plurality of pipe pigs being sufficient to substantially fill a cross-section of the first pipe section and to define a plug having a leading edge and a trailing edge such that the leading edge is in contact with a first material and the trailing edge is in contact with a second material. Each pipe pig has a nominal size that is smaller than an effective diameter of the first pipe section. The plug is moved through the piping system by moving the second material. Advantageously, mixing of the first material and the second material is inhibited by the plug.Type: ApplicationFiled: February 5, 2020Publication date: August 20, 2020Inventors: Jeffrey D. Mathews, Gerald Olean Fountain, Johnny Casasnovas

Publication number: 20200263827Abstract: Methods and apparatus provide safety systems for operating equipment having confined spaces which, during normal use, have conditions, such as extreme temperatures, pressures and/or caustic/toxic chemicals or other harmful gases which can be fatal to an otherwise healthy adult human. To protect humans inadvertently trapped in the confined space after the start of a normal operation cycle, the safety systems not only stop the equipment which is creating the harmful condition, such as a cutting off a supply of high pressure steam, but also remove the harmful condition or render it survivable. Versions also open access doors permitting escape and/or rescue of persons trapped in the confined space.Type: ApplicationFiled: February 14, 2020Publication date: August 20, 2020Inventor: Philippe Roe
