How to deal with expansion in long-distance pipelines
Thread Content
How is the expansion amount of long-distance pipelines calculated? I hope experts can provide a clear answer. Thank you
Expansion amount = Linear expansion coefficient of the material used X maximum temperature difference in the pipeline
The calculation for straight pipes can be carried out using the method applied on the 2nd floor, but if the pipeline layout is complex, more sophisticated professional calculations are required. For long pipelines, installing sections of “J-shaped” pipes at regular intervals can eliminate the need for many expansion joints. This post was last edited by river9901 on 2008-2-27 00:21.]
The professional term is: stress considerations must be taken into account during pipeline design. “∏"Bending is a common measure. The calculation method was explained upstairs; estimation is fine, but it’s best to use relevant software for design purposes. This post was last edited by bigelephat on 2008-2-27 08:31]
So what are the relevant software programs? ?
The downside of the expansion bend is that it creates more resistance
The oldest ones are software for calculating equivalent stiffness, while the most popular software today is CAESAR II
Thermal steam pipelines all require thermal compensation, with compensators in place. It’s just a few curved lines.
