The impact of temperature rise on pipelines
Thread Content
One full cycle of the lubricating oil tank, pump outlet pressure at 2 kilograms, at room temperature； Stop the pump at noon, and close the return and feed streams ； During the afternoon inspection, there was a leak in the heat exchanger on the return pipe! May I ask, what impact does an increase in oil temperature have on pipeline pressure? Is it necessary to discharge a portion of the oil after isolating the pipeline?
Does it happen often? Otherwise, it’s normal for the equipment gaskets to age; regular maintenance and replacement should suffice
