Pipe and fittings required between the pipe to provide sufficient strength to the system.
Corrugated metal pipe (cmp) corrugated metal pipe has been the drainage pipe of choice for engineers and project specifiers for over 100 years. With its various coatings, corrugation patterns, and steel thicknesses cmp provides the predictable strength, durability, and value that today’s projects require. No other pipe material on the market today can match cmp’s versatility and value.
Plastic hinges could develop if the vertical soil pressure were increased past the performance limit.
The principal object of all drainage is to facilitate the production of a subgrade of uniform bearing value and strength.
Problems concerning the application of drain pipes are limited and well understood. Covered, hence the reproducibility of the tests was low; and plastics the impact strength, brittleness, and pipe stiffness on the short and long.
Up to 60 % of raw materials can be saved in comparison to solid walled plastic pipes. The strength of the pipes is given by the corrugated design of the outer wall and not by wall thickness, as it applies for solid wall pipes. Less manpower is needed for the installation of the pipes due to the low weight. Corrugated plastic pipes can be even installed in very constrained areas.
