SUMMARY

The discussion focuses on calculating the minimal distance between two holes in a metal block, particularly when one hole is subjected to high-pressure liquids. The recommended approach involves treating the problem as a pipe wall thickness calculation, where the distance between the holes is determined by adding the calculated wall thickness to the diameter of the hole. Relevant standards such as ASME B31.1 for Power Piping and ASME B31.3 for Process Piping provide formulas and guidelines for these calculations.

PREREQUISITES
  • Understanding of ASME B31.1 Power Piping standards
  • Familiarity with ASME B31.3 Process Piping standards
  • Knowledge of stress analysis in mechanical engineering
  • Basic principles of fluid mechanics related to hydraulics
NEXT STEPS
  • Research ASME B31.1 Power Piping for relevant formulas
  • Study ASME B31.3 Process Piping for additional guidelines
  • Explore stress analysis techniques for materials with holes
  • Learn about pipe wall thickness calculations in engineering handbooks
USEFUL FOR

Mechanical engineers, structural engineers, and anyone involved in the design and analysis of metal structures with pressure considerations will benefit from this discussion.

Hello... first of all, this is my first entry, couldn't find anything similar with the search function...
so here is my problem..

Out of personal interest, i want to know if there is a formula to calculate the stress on a block of metal with two holes. One of these holes will be used for high pressurized liquids (hydraulics) while the other whole will not...
the question is how to calculate the minimal distance between these two holes? Anyone here that has a formula or may be a paper on that subject at hand!

Thanks a lot!

One simple way to do this would be to treat it as a pipe wall thickness calculation. The calculated wall thickness (plus the diameter of the hole) would be the distance between the two holes.

You could use formulas in ASME B31.1 Power Piping or ASME B31.3 Process piping. Many engineering handbooks also have these.
