hdpe pipe thrust blocks in mali

Thrust blocks and anchors must be large enough to withstand the forces tending to move the pipe, including those of momentum and pressure as well as forces due to expansion and contraction. The positioning of the thrust blocks must consider whether connections adjacent to the thrust block are capable of movement, as well as the anticipated direction of movement.

Chapter 7 Underground Installation of PE Piping 267 Figure 1 Pipe Trench Note: When groundwater levels are expected to reach above the pipe, the secondary initial backfill should be a continuation of the primary initial backfill in order to provide optimum pipe

HDPE pipe’s fused joints are self-restraining, thereby eliminating costly thrust restraints or thrust blocks. Furthermore, HDPE pipe’s fused joints virtually never leak, effectively eliminating infiltration and exfiltration problems experienced with alternate pipe joints.

HDPE Pipes and Fittings Polyethylene Piping Systems

* 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.

HDPE pipe can be bent to a radius 25 times the nominal pipe diameter (Example: 12” HDPE can be cold formed in the field to a 25 ft radius). This can eliminate many fittings required for directional changes in a piping system where fittings and thrust blocks or restraints are required with alternate materials.

HDPE pipe is strong, durable, flexible and light weight. When fused together, HDPE has a zero leak rate because the fusion process creates a monolithic HDPE system. HDPE pipe is also a more environmentally sustainable option as it is non-toxic, corrosion- and chemical-resistant, has a long design life, and is ideal for trenchless installation methods because of its flexibility.
