Glass Tube Pressure Calculator
Calculate the “Maximum Allowable Pressure” for a glass tube of given outside diameter and wall thickness (both with same unit).
This is based on the Barlow’s formula, assuming the tensile strength of glass is 4000 psi and a safety factor of 4.
Note: flaw or imperfection of the glass tube can substantially reduce the maximum allowable pressure below the calculated value.
