What is CMP in pipe?

Corrugated metal pipe (CMP) is the “go to” material for the majority of detention and infiltration projects. Pipe can be fully or partially perforated for infiltration or groundwater recharge applications. Custom access risers and manifolds provide direct access for maintenance.

What is the diameter of corrugated pipe?

Diameters range from 6 inches to 150 inches. Additionally, corrugated steel pipe is available in a range of coatings, including galvanized (zinc coated), Aluminized Type 2, and polymeric film among others.

How is corrugated pipe measured?

Corrugations are measured from crest to crest (width) and valley to crest (depth). Galvanized steel or aluminum with ½ inch high corrugations, spaced 2 2/3 inches apart.

What type of metal is CMP?

Types of CMP Corrugated metal pipe is made from steel and aluminum. CMP can be enhanced with different coatings that extend service life and protect the metal drainage pipe from corrosion.

How do I calculate discharge pipe size?

The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.

How deep should a culvert pipe be?

Cover the culvert with soil to a depth of at least 12 inches, or at least 1/2 of the diameter for larger culverts (Figure 6). For example, a 36-inch culvert should have a soil cover at least 18 inches in depth.

What is the thickness of HDPE pipe?

hdpe pipe sizes and dimensions PE100 can be manufactured in a wide range of pipe diameters from 16mm to 2000mm. Even larger diameters are possible with the development of appropriate extrusion dies. However the common range of pipe sizes is from 32mm to 1200mm.

What is corrugated metal pipe culvert?

Corrugated steel culverts, storm drains and sub drains are vital to the protection of streets, highways and railroads. Corrugated steel pipe & plate culverts provide reliable, economical solutions to handle the flow, including debris, with minimum damage to the slope or culvert barrel.

What is the thickness of steel pipe?
