CSP ATTRIBUTES & BENEFITS
Corrugated Steel Pipe (CSP) is manufactured to exacting specifications to ensure a high quality product that is optimized for strength, durability, ease of installation, sustainability, and economy. CSP is a flexible material that combines the strength of steel and the stiffness of corrugation with the load bearing abilities of backfill to manage the forces of soil and water. The result is a strong product with outstanding longevity and durability.
Manufacturers offer CSP in a variety of sizes, lengths, corrugations, and thicknesses with coatings to extend life cycles and stand up to aggressive conditions. Understanding the Canadian environment, the CSPI helps engineers decipher information, providing detailed material specifications, load calculations and tables, hydraulic parameters, and design service life analyses to assist in material selection for the right soil and water management solution to support a sustainable future.
CSPI and manufacturers use studies to understand and quantify the durability performance of CSP, including:
DSL (DESIGN SERVICE LIFE)
By estimating project life designers set a target to ensure the most efficient selection of materials and economical design.
EMSL (ESTIMATED MATERIAL SERVICE LIFE)
Taking into account abrasion loads, soil and water Chemistry, CSP thickness and coating type a material with a service life (EMSL) that matches the Design Service Life (DSL) can be selected.
CSP MATERIALS
Includes Polymer Laminated Galvanized Steel; Aluminized Type 2 Steel; and Galvanized Steel.
TESTING
Simple on-site water testing leads to sound material selection. Registered quality control procedures assure CSP product excellence.
CSP is not just a pipe!
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.
CSP CHARACTERISTICS
Coating Alternatives
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. Read more
Construction Methods
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. Read more
Corrugation Profiles
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. Read more
Durability
Many factors determine the lifetime performance of a CSP installation. Matching Estimated Material Service Life (EMSL) to Project Design Service Life (DSL) optimizes economics. Read more
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. Read more
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. Read more
Pipe Shapes
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. Read 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. Read more
Steel Chemistry and Specifications
The steel materials and CSP are manufactured to exacting standards that are detailed in Canadian Standards Association CSA G401. Link
