Maximum cover of 50 ft, with or without traffic, rail, or surcharge loading; minimum cover of at least one diameter or 18-in., whichever is greater. Earth pressure applied to the pipe is determined using the prism load (geostatic soil stress).
HDPE pipe shall not be used in appliions where the depth of cover exceeds 10 feet. The minimum cover shall be 18 inches. In appliions where 18 inches of cover can not be obtained, cover of 12 inches or more may be allowed with Engineer approval.

Minimum Cover Heights in Trafficked Conditions Pipe with diameters of 4- to 48-inch installed subjected to AASHTO HL-93, H-25 or HS-25 traffic loads must have at least one foot cover over the pipe crown, while 60-inch diameter pipe must have at least 18
For buried penstock sections, a minimum soil cover of 1 m is recommended as in the case of HDPE headrace pipe, and the trench details should be similar to those shown in Figure 4.8 (Chapter 4). 6.3 Pipe materials In Nepal the most commonly used penstock Puhui Pipe manufacturer in China
Features of HDPE pipes and fittings: Green environmental protection: HDPE pipe non-toxic, tasteless, after strict health monitoring, belongs to green building materials, never scale, can effectively improve water quality. Corrosion resistance: HDPE pipelines are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipeline.

HORIZONTAL DIRECTIONAL DRILLING - TECHNIQUE When new pipe is to be installed or it is not possible to rehabilitate a pipe, so that it needs to be replaced but is in a congested area of buried infrastructure so that conventional methods such as bursting cannot be used safely, then a new or replacement PE100 pipe can often be installed by horizontal directional drilling.
* HDPE pipe may face; PE density of 94% of the salt water, because it is up to 96% of the fresh water on the HDPE pipe filled with water even if the water is suitable to swim in. Therefore, be reduced as far as large parts of the ground may be left floating on the water coined.

Poly (HDPE) pipe lengths vary according to size, however, generally sizes up to 110mm are available in 6 metre straight lengths or 50m, 100m or 150m pipe coils. Sizes 125mm and above are generally available in 12 metre lengths, which offers huge cost savings by reducing nuers of onsite joins.
CHAPTER 5: DESIGN METHODOLOGY Overview of Structural Considerations All pipe, whether flexible or rigid, relies on the backfill structure to transfer loads into the bedding. As a result, all pipe also must be installed as designed to perform as expected. This
