Aug 23, 2022 · The internal pressure rating of a pipe is determined by the equation: PR = [2HDS (fE) (fT)] / (DR-1) This formula calculates the pressure rating by (1) determining the product of double the material’s hydrostatic design stress at 73°F, multiplied by the unique operating temperature multiplier and environmental design factor, and then (2.

.

The process included the use of catalysts and low pressure, which is the basis for the formulation of many varieties of polyethylene compounds.
