When the thickness does not exceed one-half of the inside radius, 1

[fixo]

The subject , from the ASME VIII UG 27 states

When the thickness does not exceed one-half of the inside
radius, use the given formula ..and so on

My question: for a given hollow diameter no more than 10 mm
known the material property as
S = maximum allowable stress value
Static pressure, no flow.It shall be up to 7000 BARg
Ambient temperature about 25 °C
What shall be the thickness?

7001 Bar a... And you are building to Section VIII Div. 1?

Seek professional help. Before someone gets hurt.

Exactly what jte said.

With high design pressures the thickness rules of Section VIII division 1 do NOT apply.

The question implies insufficient expertise. With these pressures a professional mechanical engineer with experience in (high) pressure technology MUST be in responsible charge.
