Systems and methods for transporting a hydrocarbon are provided. The method can include introducing a fluid at a first pressure and a first temperature to an inlet of a pump and pressurizing the fluid within the pump to produce a pressurized fluid having a second pressure and a second temperature. The method can also include flowing at least a portion of the pressurized fluid through a first heat exchanger and back to the inlet of the pump. The heat exchanger can include a coil having an inlet and an outlet and a housing at least partially enclosing the coil and having a first opening and a second opening. A first end of the coil can be disposed proximate the first opening. The heat exchanger can also include a foundation for supporting the coil and the housing.

Subsea pipe-in-pipe structures

A pipe-in-pipe assembly with thermally-insulating spacers positioned in an annulus to act radially between inner and outer pipes is disclosed. The spacers have at least one circumferentially-extending array of circumferentially-spaced ribs that define longitudinally-extending passageways in gaps between neighbouring ribs of the array. Cables including heating elements extend longitudinally along, the annulus outside the inner pipe. The cables extend longitudinally along the passageways. At least one insulation layer disposed radially outboard of the cables has insulating elements disposed in the gaps between the ribs and/or an insulating layer extending around the inner pipe, positioned radially outboard of the ribs and bridging the gaps. Bands encircle and retain components of the insulation layer. Insulation may also be disposed on the inner pipe between first and second arrays of ribs, those arrays being spaced longitudinally from each other.

Fluid line
10539262 · 2020-01-21 · ·

The invention relates to a fluid line (1), comprising a pipe (2), which has an inlet-side end segment (3) having a first connector (5) and an outlet-side end segment (4) having a second connector (10), wherein a cavity (17) bounded in the radially inward direction by at least one auxiliary element (16) is formed in the pipe (2). The problem addressed by the invention is that of minimizing the requirements for the suction performance of a pump that is used to convey a liquid through the pipe. This problem is solved in that a volume reduction element (18) is arranged in the cavity (17) at least in the region of the outlet-side end segment (4).

Flexible conforming silicone rubber heater for complex geometry fluid lines and method

A flexible, substantially lamellar silicone foam rubber-based heater for heating fluid lines such as high temperature gas supply and exhaust lines used in microelectronic semiconductor fabrication uses a flexible, oblong substantially longitudinally uniform heater body including an oblong block of a thermally conductive, resiliently compressible material for conforming the heater to a line of complexly shaped components connected in series. The block can be supported by a silicone rubber support layer in contact with a flexible heater element containing layer, and an outer silicone foam rubber insulation layer. Fasteners, such as separatable retaining bands spaced along the line can hold the heater in place. A matable pair of bodies, or a single folded body can enwrap the line.
