MDPE (Medium Density Polyethylene Pipes) Pipes are used for the transportation of gas as well as for water all over the world due to its best technical and operational characteristics. Medium Density Polyethylene has a density between 0.926-0.940 g/cm 3.

The least material condition is used to manage the size and position of holes, as well as the thickness of the material. For example, if a part’s hole has imprecise size or position under the least material condition (the hole has maximum size), the part will have insufficient strength and may break. The least material requirement is useful for designing parts with such strict space requirements.

The most undesirable condition in terms of designing thickness is when the hole diameter is large (least material size) and the hole is positioned close to the edge. In contrast, when the hole diameter is small (maximum material condition), strength can be maintained even when the hole is close to the edge.
