Detailed design of a certain cooler – how were the hydrostatic test pressures of 0.87 and 1.17 MPa determined in the diagrams? Thank you!
4.6.2.2 in GB/T150.1-2011
Refer to the provisions in HG/T2650-2011; see the attached diagram
The top design specification should be revised to include HG/T3650-2011; many devices do not need to comply with this standard. /
What is indicated in the figure: the allowable stress of the material at the test temperature. At what temperature is this test conducted? The material is S30408 – which standards should be referred to? Thank you!
I see now; the test temperature is based on 20 degrees Celsius at normal conditions, and the allowable stress can be found in GB 50316
What standard is HG/T3650-2011?
He wrote it wrong; it’s HG/T2650-2011
How did the 10% value for non-destructive testing in the first image come about? In the second diagram, the water is the heat flow stream; can it also be handled according to standard 2650 «Water-Cooled Tubular Heat Exchangers»?
