Discussion on the issues of low, medium, and high pressure in the budget quotas for process pipelines
Thread Content
When determining the quota for pipes, corresponding sub-items of the appropriate pressure grade are selected based on the design pressure. I would like to ask: if the pipe is of low pressure, does that mean the fittings as well have to be of low pressure? Are flanges and valves classified by pressure rating in terms of pound ratings? Or should it be calculated based on the pipeline?
It should be based on the pipes; pipe fittings belong to a certain category, and high-pressure valves require even stricter installation requirements
I remember that the compilation on quota explanations for flanges stated that it should be calculated separately based on the pressure rating, but the audit said it should be calculated based on the pipeline, just as you were told?
