Design Pressure Polyethylene Pipe

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.

Limitations include pressure in distribution and class 3/4 areas, temperatures below -20 degrees and above 150 F, wall thickness, and certain type of materials.

Where:
𝑃 = Internal Pressure ,psi.
𝑆 = Hydrostatic Design Basis, [psi](1600 for polyethylene pipe) 𝑆𝐷𝑅 = Standard Dimension Ratio ,D/t.
𝐷 = Outside Diameter ,in.
𝑡 = Minimum Wall Thickness ,in.
𝐹 = Design Safety Factor (0.5 for water @ 73℉)
