Slip Liner System
for Bridges, Railways, & Culverts
Easily meet flow, design life and structural requirements with site-specific steel culvert liners by InfraSteel
A common culvert rehabilitation challenge is finding a solution that meets strict flow capacity requirements, design-life requirements, and at the same time increases the structural integrity of the failing culvert where detours are impractical. Culvert manufacturers like InfraSteel design and fabricate culvert lining systems that easily meet and often exceed these requirements.
Why Infrasteel?
InfraSteel culvert liners are designed
site-specific
We work meticulously with project engineers until all requirements are met.
1
Measure
Measurements are taken of the host pipe that enable us to match the radii of the existing structure.
2
Design
Liner drawing is produced by InfraSteel based on measurements and project requirements.
3
Revisions
Drawing goes through revisions based on review from structural, hydraulic and manufacturing engineers.
4
Production
We then provide a cost estimate and template of the culvert lining system that is used to verify dimensions. Once approved the order is entered for production.
Site-specific design maximizes hydraulic capacity
Each culvert lining system is designed to maximize the total water way area, thereby improving or preserving existing hydraulic conditions.
InfraSteel culvert liners are made using smooth wall carbon steel with a Manning’s Coefficient of .012.
Calculated design life to meet project requirements
Design life is built into the thickness of the steel. If a project owner wants a 70-year design life we add 70 years of sacrificial steel to the wall thickness of the liner. Destructive testing by Caltrans determined that ID coatings for stormwater applications are quickly removed by abrasion.
Superior structural integrity without the compromise
As a reputable culvert manufacturer with over 20 years of experience, InfraSteel is highly proficient in offering solutions for culvert projects, where structural integrity is a major concern. InfraSteel’s steel culvert liners can be installed without disrupting traffic or rail operations. After joint welding, the end product will be one solid steel structure without the possibility of joint failure.
