HDPE Pressure Pipe - Water / Sewer

HDPE pressure pipe is used in water distribution, sewer force mains, reclaimed water systems, and industrial applications where a durable, leak-free pipeline is required. Manufactured from PE4710 resin and produced to AWWA and ASTM standards, it is available in a range of pressure ratings to match system requirements. Heat-fused joints create a continuous, fully restrained pipeline that eliminates mechanical joints and reduces the risk of leaks over the life of the system. Galloway stocks HDPE pressure pipe in the sizes, DR ratings, and material grades used across municipal and industrial infrastructure.

Pressure rating by Dimension Ratio (DR)

DR (Dimension Ratio) describes the relationship between pipe outside diameter and wall thickness. Lower DR values indicate thicker walls and higher pressure capacity:

DR

PSI

Typical Applications

DR 7

335

High-pressure water transmission, industrial process lines, force mains

DR 9

255

Municipal water distribution, sewer force mains, industrial systems

DR 11

200

Standard municipal water mains, reclaimed water, general utility service

DR 13.5

160

Low-pressure water distribution, irrigation, light-duty force mains

DR 17

125

Sewer force mains, reclaimed water, low-pressure utility service

DR 21
