Should the weight of the condensate be considered when calculating?
Thread Content
When calculating chemical pipelines, should we consider the weight of the condensate? Consider it in percentage. Also, should we consider the weight of water during hydraulic testing? What percentage should be considered? Thanks in advance!
Condensate in large-diameter pipelines is considered at 10%, and the hydraulic pressure test is 100%.
I would like to ask you which pipeline needs to consider so much condensate? After the hydraulic pressure test is completed, it needs to be purged. Why is it still so heavy? Moreover, do temporary supports and hangers need to be added during the hydraulic test? I don’t understand, please introduce it in more detail.
What does the "chemical pipeline calculation" here calculate? What tool do you use to calculate it? If you are calculating primary stress, support strength, and civil construction conditions, you only need to consider the flushing weight. If you perform process calculations and calculate the secondary stress of the pipe, you do not need to consider the hydraulic test. if. . . . . So many possibilities. So, be clear when asking questions. . . . Otherwise, we will have no enthusiasm and you will scratch your head and scratch your head anxiously, but you will not be able to help us.

6.2.2 When condensable gas is transported in a pipe, the weight of the medium should be calculated based on the actual weight of the condensate in the pipe. The weight of condensate in horizontal pipelines can be estimated according to the following regulations: a) When the nominal diameter of the pipe is less than 100 mm, 50% of the liquid weight of the full pipe may be taken: b) When the nominal diameter of the pipe is 100 mm~500 mm, 15% of the liquid weight of the full pipe may be taken; c) When the nominal diameter of the pipe is greater than 500 mm, 10% of the liquid weight of the full pipe may be taken. See SH/T 3073 - 2004 "Specifications for Design of Supports and Hangers for Petrochemical Pipelines" Hydrostatic Test: Consider water weight ； When designing the bracket, there are two types: water weight is considered and water weight is not considered (temporary pipe racks are set up). Generally, water weight is considered.
