Abstract: A suspension frame assembly of a magnetic levitation vehicle, includes multiple suspension frames which are sequentially connected; and each suspension frame includes two longitudinal beam bodies arranged in parallel. A supporting wheel and a holding arm are fixedly provided on both ends of each longitudinal beam body; and two anti-rolling devices mounted between mounting frames of two of the supporting wheels at a same end of the two longitudinal beam bodies; and the two longitudinal beam bodies of one of the suspension frames are respectively hingedly connected to the two longitudinal beam bodies of an adjacent suspension frame; an air-spring arm beam is provided at a hinged part of the two suspension frames, and is mounted on the holding arm of one of the two longitudinal beam bodies which are hingedly connected.

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.
