Instruction on how to calculate the pressure of steel pipes

Why do we need to calculate the pressure inside the pipe when constructing a pipeline system, an oil or gas pipeline? To answer this question, let's explore the post below with VHE to understand how to calculate the pressure inside cast steel pipes at minimum yield strength!

Most people, when buying steel pipes for installation, do not know how to do pressure calculations to choose the right type of pipe. Therefore, when calculating this value, we can know whether to choose a thick tube or not. Or choose a tube with a larger diameter.

Below is the pressure calculation formula derived from the scientific research work of mathematician Peter Barlow. This is the formula that has been recognized by many scientific councils around the world and is used in many places as a standard to determine material quality.

Formula to calculate the working pressure of steel pipes:

And:

  • 1 Mpa = 1,000,000 Pa
  • 1 Mpa = 1,000 kPa
  • 1 MPa = 10 Bar
  • 1 Mpa = 1,000,000 N/m2
  • 1 MPa = 100 N/cm2
  • 1 Mpa = 1 N/mm2
  • 1 Mpa = 1,000 kN/m2
  • 1 Mpa = 0.1 kN/cm2
  • 1 Mpa = 0,001 Kn/cm2
  • 1 Mpa = 101,971.6213 kg/m2
  • 1 Mpa = 10.19716213 tons/cm2
  • 1 Mpa = 0.1019716213 kg/mm2
  • 1 Mpa = 101.9716213 tons/m2
  • 1 Mpa = 0.01017916213 tons/cm2
  • 1 Mpa = 0,0001017916213 tons/mm2
