Is a 304 stainless steel pipe with a pressure rating of 2.5 MPa, DN80, and a wall thickness of 3 mm safe for use?
Safety is no issue, provided the pipes do not corrode
There is only pressure, no temperature, and the medium is unknown – how can one determine whether it is safe! If it’s not a pressure pipeline, there are no major safety issues anyway, so you can use it with confidence ； If it is a pressure pipeline, further review is required.
As long as the requirements are met, there’s no problem at all. For specific details, refer to the chemical pipeline design manual: for 2.5 Mpa, DN80 corresponds to 3 mm
With this thickness, welding isn’t a problem. Ignoring everything else, considering both the pressure and the material, 1 mm of thickness is sufficient
Based on calculations, it should be safe to use this pipeline at temperatures below 630°C. For your reference
What I’m worried about is the negative deviation of the pipeline – will that mean it doesn’t meet the specifications?
