Cold and heat compensation methods for the fluid-conveying horizontal pipeline

Provides formulas for calculating the expansion amount and axial force, compares the combination of fixing trestles(pipe hangers), guiding trestles(pipe hangers) and expansion joints with the combination of fixing trestles(pipe hangers), guiding trestles(pipe hangers) and self-compensation, and analyses their respective advantages and disadvantages. Puts forward the axial/ transverse movable trestle mode, in which pipes can slide freely within the limits of trestles (hangers). This way has been successfully applied to several projects and achieves desirable results.
