Not Just A Pipe!
Years of dependable service and a multitude of wide ranging installations have led the corrugated steel industry to play a major role in modern engineering technology for drainage systems. Flexible steel conduits play an important role in the form of culverts, storm sewers, spillways, underpasses, conveyor conduits, service tunnels, detention chambers and recharge systems; for highways, railways, airports, municipalities, recreation areas, industrial parks, flood and conservation projects, water pollution abatement and many other programs.
Coating alternatives are used to extend the service life of CSP in specific environments. CSP Materials available (as per CSA G401) include Polymer Laminated Galvanized Steel; Aluminized Type 2 Steel; Galvanized Steel. Pipes and plates may also be coated or lined after fabrication or installation to meet specific site requirements.
Properly constructed soil and steel installations give CSP superior strength. Learn about essential handling, installation, and construction procedures for unloading and assembly of CSP, base preparation, placement, and compaction of the backfill. Emphasis is on CSP in embankment installations such as highway culverts.
Standard corrugations range in depth from 6.5 mm for the smallest CSP to 150 mm for large Deep Corrugated Long Span Structures. A Spiral Rib profile provides a smooth interior wall for improved hydraulics in storm sewers.
Many factors determine the lifetime performance of a CSP installation. Matching Estimated Material Service Life (EMSL) to Project Design Service Life (DSL) optimizes economics.
Hydraulic Characteristics and Capacities
Many factors including slope, shape, and size of the inlet and corrugation profile affect the flow of water through a CSP. Use hydraulic formulas and charts for determining water flows and capacities when designing drainage sites that protect people, the environment, and infrastructure.
Load Carrying / Height of Cover
Structural design formulas and Load Tables ensure optimum design. Check here for inside dimensions, specified wall thickness, and covers for all pipe shapes. Includes sample calculations.
While round is the most common and often the most efficient and economical shape, CSP is available in various shapes to match specific site and environmental requirements. Shapes include round, pipe arch, elliptical, open bottom arched, pear shaped, box culverts and more.
Pipe Sizes & Handling Weights
CSP is lightweight and nestable providing for economical transportation, plus numerous construction and handling advantages. From 150 mm diameters to arches that span more than 25 meters – check here for CSP standard round and pipe-arch shape diameters, end areas, and handling weights.
Steel Chemistry and Specifications
The steel materials and CSP are manufactured to exacting standards that are detailed in Canadian Standards Association CSA G401.
