Wall Thickness Polyethylene Pipe

Contents

Introduction

Polyethylene Line Pipe is designed in accordance to API 15LE based on material designation of specified pipe size and wall thickness, standard dimension ratio, temperature and design factor i.e. 0.32.

Wall thickness must meet minimum thickness in accordance to DOT 192.123. : t=\frac{PD}{2S+P}F

t=\frac{PD}{2S+P}F

Where:
𝑃 = Internal pressure [psi]
𝑆 = Hydrostatic Design Basis [psi]
𝐷 = Outside Diameter [in]
𝑡 = Minimum Wall Thickness [in]
𝐹 = Design Factor
