Technical reference data:
There a three commonly used formulas for calculating the burst pressure of seamless hydraulic tubing, Barlow's formula, Boardman's formula and Lame's formula. Once the theoretical burst pressure of the tube has been calculated using one of these formulas, working pressure is calculated by dividing the burst pressure by a desired factor of safety. This document contains a table of reference working pressures in psi of seamless steel tube calculated using Barlow's formula, based on a minimum ultimate tensile strength of 50,000 psi and a design safety factor of 4:1.
