ASTM C118/C118M-24 PDF

Overview

ASTM C118/C118M-24 – Standard Specification for Concrete Pipe for Irrigation or Drainage defines the manufacturing and acceptance criteria for nonreinforced concrete pipes used in the conveyance of irrigation water, including applications under working and transient pressures, as well as for drainage systems. This internationally recognized standard specifies requirements for design, joints, material components, physical properties, and testing, ensuring that concrete pipe products reliably meet the needs of both irrigation and drainage infrastructures.

Key objectives of ASTM C118/C118M-24 include establishing uniform criteria for pipe dimensions, material properties, quality control tests, and permissible variations-facilitating the construction of safe, durable, and efficient water management systems.

Key Topics

• Scope and Purpose

  • Specifies nonreinforced concrete pipe for both pressurized irrigation water and drainage
  • Applies to manufacturing and purchase, not installation or field repair procedures
  • Supports both imperial and metric units for international applicability

• Design and Material Requirements

  • Detailed dimensions for pipe diameters, wall thickness, and minimum strength ratings
  • Materials used must meet referenced ASTM standards for aggregates, cementitious materials, admixtures, and water
  • Joints designed for watertight continuity and structural compatibility

• Testing and Acceptance

  • Acceptance determined by three major tests:
    • Three-edge-bearing load test: Measures pipe structural strength
    • Absorption test: Ensures low water absorption for durability
    • Hydrostatic test: Confirms resistance to internal water pressure with minimal leakage
  • Pipe must also comply with inspection standards for surface quality and dimensional tolerances

• Classification and Marking

  • Products classified as standard concrete irrigation pipe, standard drainage pipe, or heavy-duty drainage pipe
  • Heavy-duty pipes are marked with the letter "H" for easy identification

Applications

ASTM C118/C118M-24-compliant concrete pipes are employed in a range of civil engineering and agricultural settings, providing key advantages for:

• Irrigation systems:

  • Transports water under steady or variable pressures across farmland
  • Designed for performance under hydraulic transients, ensuring reliability in demanding operating conditions

• Drainage infrastructure:

  • Manages stormwater and surface flows, preventing flooding and erosion
  • Used in agricultural drainage, culverts, roadway edge drains, and field tile systems

• Municipal and land development:

  • Essential in public works projects that require robust water conveyance infrastructure
  • Offers standardized, cost-effective solutions for both new construction and retrofitting

Compliance with ASTM C118/C118M-24 provides assurance of product quality and long-term performance across varying environmental and service conditions.
