duromaxx hdpe pipe construction and uses - armtec ltd
DESCRIPTION
This informative tutorial by industry leading Armtec Ltd., provides details on Duromaxx HDPE pipe construction and its advantages. This product is a steel reinforced polyethylene pipe that is generally used in the construction of road culverts, storm sewers, storm water detention systems and structure relines. As outlined in the tutorial, DuroMaxx corrugated steel pipe has several advantages including the fact that it is impact resistant to avoid installation damage, UV resistant, abrasion resistant, chemical resistant to strong acids and bases (pH range 1.25 to 14) and finally allows for fast installation as it is lightweight and can be trimmed to the length you need. The tutorial demonstrates how the pipes are created and rigorously tested. Armtec Ltd., is a leading supplier of DuroMaxx pipes in Canada.TRANSCRIPT

High Strength – High Performance Steel
• Strength comes from Steel Rib
• 80 ksi galvanized steel rib vs 35 ksi in CMP
• Steel provides predictable long term performance.
• Minimum HOC = 300mm, Maximum = 9M to 15M depending on diameter
