Freezing around a pipeline carrying cooled gas in flooded areas

Journal Article:

Abstract

The USSR's NIPIESUneftegazstroi mathematically analyzed the problem of ice formation around a subcooled-gas pipeline submerged in water in cold regions and derived charts for determining heat-transfer coefficients and the rate of ice formation for various water and gas temperatures. Because the ice halo that forms around these pipelines necessitates additional anchoring of the line, NIPIESUneftegazstroi sought to quantify the weight required in order to minimize the cost and material needed. The differential heat-transfer equations given can be used to calculate heat-transfer coefficients and the specific heat flux from the water to the ice halo, as well as the radius of the ice halo. Values of the ice-halo radius are plotted graphically as parabolic function of time (to 15,000 h) for pipeline surface temperatures of 30.2, 27.5, 23, 18.5, and 14/sup 0/F. An equation indicates the limiting value of the temperature of the transported gas at which icing of an insulated pipeline will not occur.
