The thermal spalling resistance of a glass coating on a pipe in the petrochemical industry was investigated. It was found that the thermal spalling resistance of a glass coating on a pipe degrades sharply with increasing thickness of the coating. This phenomenon is associated with an increase of the temperature gradients on heating or cooling of thick coatings as compared with thin coatings on pipes. It was determined that the high thermal spalling resistance of a glass coating on a pipe depends primarily on the thickness, brand, and geometric dimensions of the coating and the steel pipe.

管道玻璃涂层的抗热剥落性

研究了石油化工行业中管道上的玻璃涂层的抗热剥落性。已经发现，随着涂层厚度的增加，管道上的玻璃涂层的抗热剥落性急剧下降。与管道上的薄涂层相比，这种现象与加热或冷却厚涂层时温度梯度的增加有关。已经确定，管道上的玻璃涂层的高抗热剥落性主要取决于涂层和钢管的厚度，品牌和几何尺寸。
