Abstract: Spacers are provided for maintaining annular tube spacing, particularly at tube ends, in coaxial tubing systems, while also proving fluid passages ways permitting fluid flow between tubes of the coaxial tubing system. The spacers may be made of conductive material for enabling electrical coupling of the inner and outer tubes, and thus grounding of the inner tube. The spacers define a retention groove extending around their periphery for receiving a crimped portion of the outer tube, so as to mechanically fix the spacer in a longitudinal position relative to the coaxial tubing system. Accordingly, the spacer does not rely on “springbuck” characteristics of bent coaxial tubing systems for fixation, and thus is suitable for use in both bend and unbent portions of coaxial tubing systems.

Abstract: Provided herein is a liner that can be loosely inserted in process pipe to form a lined pipe and to decrease the rate of heat transfer between process fluids flowing through the liner and the process pipe. The liner provided herein can reduce applied thermal loading on the outer pipe resulting from, for example, turbulent mixing between fluids having different temperatures (with or without stratification), circumferential thermal gradients, and/or longitudinal thermal gradients. An annulus between the process pipe and liner can be at least partially filled by process fluids, thereby creating a thermal buffer to further decrease the rate of heat transfer between the fluids and the process pipe.

Abstract: Disclosed fluid flow modifying devices are useful with flexible fluid flow conduits. Such devices are adapted for mitigating adverse flow considerations arising from one or more bends in flexible fluid flow conduits. These adverse flow considerations are generally characterized as enhanced laminar flow and associated increased backpressure arising from reduced flow velocity caused by the one or more bends. Beneficially, disclosed fluid flow modifying devices cause flow of flowable material (e.g., a liquid) within a flow passage of a fluid flow conduit to have a rotational flow profile. Such a rotational flow profile advantageously reduces frictional losses associated with laminar flow and with directional change of fluid flow.
