A heating jacket wrapping a pipe of semiconductor manufacturing equipment includes an internal shell wrapping an outer circumference of the pipe and having an insulation function, a heating line arranged on the outside of an internal shell, a vacuum insulation panel (VIP) wrapping the outside of the heating line, and an external shell wrapping an external surface of the VIP and having an insulation function. A plurality of heating jackets are connected to one another in a longitudinal direction of the pipe. Temperature sensors are arranged in some of the plurality of heating jackets. Temperature sensors are not arranged in the others of the plurality of heating jackets.

The present invention relates to an assembly including an end-fitting for terminating an unbonded flexible pipe and an unbonded flexible pipe. The unbonded flexible pipe includes a first and a second armour layer co-axially arranged, and an electric heating system. The end-fitting includes means for mechanically anchoring the first armour layer to the end-fitting and includes electrical connections for connecting the first armour layer to a power-source. The end-fitting also includes means for mechanically anchoring the second armour layer to the end-fitting. The first and the second armour layers are electrically insulated from each other by at least one electrically insulating layer in the end-fitting and the end-fitting includes a local volume in the end-fitting adjacent to the electrically insulating layer adapted for injection of a functional fluid.

A silicone heater assembly is provided. The silicone heater includes a heater and a thermal pad. The thermal pad is configured to couple to the heater. The thermal pad is configured to conform to a plumbing infrastructure to be heated.

A heater of an external tubular sleeve for repairing a longitudinal section of defective hollow pipe has a frame for encompassing the sleeve when operationally positioned. Each of several burners spaced at intervals about the frame as nozzle for heating the sleeve, and a novel baffle located intermediate the nozzle and sleeve when operationally positioned, for heat dispersal over the sleeve. Each baffle has staggered vents for passing flame from the nozzle onto the sleeve, to avoid cold spots on the sleeve below the baffle, and has a central shaped deflector proximate the vents and facing the nozzle. Flame from the nozzle impacts the deflector and redirects toward the vents and periphery, of the baffle, to avoid point heating below the nozzle and provide diffused flame uniformly over the sleeve. Changing deflector and vent features can influence desired flame dispersal characteristics.

Construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member. The coupling member surrounds an armor layer at a free end of the flexible pipe or hose. A sealing area is defined by a recessed portion of the pipe coupling into which a sealing material is introduced. An inner liner layer of the flexible pipe or hose may extend into the sealing area where it is bonded to the sealing material. The sealing material and the inner liner layer may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material may be provided in the inner liner layer.

An apparatus includes a Polymer Thermal Expansion Based Passive Thermal Diode (PTE-PTD) that includes layers and is configured to provide passive heating and cooling of a pipeline. A polyurethane (PU) layer is provided that is configured to contact at least an upper portion along a length of a pipe. A polyethylene terephthalate (PET) layer is provided that is configured to surround the PU layer and the length of the pipe. A graphene layer is provided that is configured to surround an epoxy layer. An epoxy shell is provided that is configured to surround the graphene layer. An air gap on a first side of the PTE-PTD is provided. The air gap is formed by a void in the PET layer and is configured to provide additional air space between the PET layer and the PU layer. The air gap provides an upward movement of the PET layer using opposite forces of alternate sides of the PET layer. The PTE-PTD is installed on the pipeline.

An apparatus includes a method for providing a Shape Memory Polymer Based Passive Thermal Diode (SMP-PTD) that includes layers and is configured to provide passive heating and cooling of a pipeline. The SMP-PTD includes a polyurethane (PU) layer configured to contact at least an upper portion along a length of a pipe. The SMP-PTD further includes a polyethylene terephthalate (PET) layer configured to surround the PU layer and the length of the pipe. The SMP-PTD further includes a graphene layer configured to surround an upper side of the SMP-PTD and cross layers of the SMP-PTD toward a bottom side of the SMP-PTD to establish contact with the pipe. The SMP-PTD further includes an epoxy shell configured to surround the graphene layer. The SMP-PTD further includes a shape memory polymer (SMP) ring configured to provide vertical displacement and push upward upon lateral displacement from pushing by left and right PET blocks. The SMP-PTD is installed on the pipeline.
