A pipeline is only as strong as its weakest connection. When it comes to joining HDPE pipe, there are several common methods that are used, each with its advantages and disadvantages. In this article, we’ll discuss four different methods: butt welding, electrofusion, flanging and mechanical coupling – focusing predominantly on the ease and speed of installation, the need for specialised equipment and experienced personnel, and the strength and reliability of the joint.

In most respects, installing corrugated high-density polyethylene (HDPE) pipe is like working with any other material: The pipe system’s strength is a combination of the pipe itself and the backfill envelope. Proper construction maximizes the drainage capabilities designed into the pipe by maintaining alignment and load-carrying ability.

In a properly constructed backfill envelope, loads are distributed across the pipe’s crown to the backfill material along the sides of the pipe and then to the pipe bedding and foundation. With flexible material like corrugated HDPE, however, this load arching effect tends to reduce the total soil column load applied to the crown.

The load that a flexible pipe will carry is related to the backfill envelope construction. The load-carrying capacity of a pipe/backfill system will be determined by a combination of the backfill material, the level of compaction, and the placement of the backfill material. The application may also influence what type of backfill is required.

Material selection is the first step to creating a structurally sound backfill envelope. In general, it should be of an aggregate nature and have the ability to be compacted, if necessary, into a structurally sound arrangement. A variety of materials, including some native soils, meet these requirements.
