Standard Specification for Aluminum Alloy Sheet for Corrugated Aluminum Pipe

ABSTRACT
This specification covers aluminum alloy sheets used in the fabrication of corrugated aluminum pipe intended for use for storm water drainage, underdrains, culverts, and similar uses. The material is furnished corrugated in cut lengths, and uncorrugated in coils and cut lengths. The sheet material's thickness, chemical composition, and mechanical properties shall be determined.
SCOPE
1.1 This specification covers aluminum alloy sheets used in the fabrication of corrugated aluminum pipe intended for use for storm water drainage, underdrains, culverts, and similar uses. The material is furnished corrugated in cut lengths, and uncorrugated in coils and cut lengths.  
1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM B744/B744M-15(2020), issued by ASTM International, provides the standard specification for aluminum alloy sheet materials used in the fabrication of corrugated aluminum pipe. This type of corrugated aluminum pipe is essential for stormwater drainage, underdrain systems, culverts, and similar civil infrastructure applications. The specification details requirements for dimensions, mechanical properties, chemical composition, and product marking to ensure consistent quality and suitability for demanding environments.

Key Topics

• Material Scope: Covers aluminum alloy sheets provided either corrugated in cut lengths, or uncorrugated in coils and cut lengths for use in fabricating corrugated aluminum pipe for stormwater and drainage projects.
• Dimensional Specifications: Defines sheet thickness options, permissible tolerances for width, length, flatness, and the geometry of corrugations. Thickness and dimension tolerances are specified in both SI and inch-pound units.
• Mechanical & Chemical Properties: Requires that sheet material meet chemical composition and mechanical property benchmarks in accordance with ASTM B209/B209M.
• Product Marking and Traceability: Outlines strict requirements for product identification, including manufacturer details, alloy and temper, thickness, production date, and relevant ASTM designation, ensuring traceability throughout the supply chain.
• Ordering Information: Details the need for clear specifications in purchase orders, such as sheet thickness, quantity, coil size, and corrugation size, to streamline procurement and fabrication processes.
• Sampling and Testing: Specifies that appropriate sampling, testing, and record-keeping are performed to ensure compliance with all requirements.

Applications

Aluminum alloy sheets conforming to ASTM B744/B744M are mainly used in the manufacturing of corrugated aluminum pipe for:

• Storm Water Drainage Systems: Ensures durability, corrosion resistance, and ease of installation for efficient runoff management.
• Underdrain Networks: Supports soil stability and groundwater control by channeling subsurface water flows.
• Roadway and Highway Culverts: Provides robust performance and longevity under traffic loads and environmental exposure.
• Municipal Water Infrastructure: Enables the construction of reliable and low-maintenance water conveyance structures.
• Custom Infrastructure Solutions: Applies to special civil engineering designs where lightweight and corrosion-resistant pipe is needed.

The specification's focus on chemical composition, mechanical requirements, and dimensional tolerances makes it integral for fabricators, engineers, and contractors seeking compliance and proven performance for critical infrastructure projects.

Related Standards

ASTM B744/B744M references several other important standards to maintain a comprehensive framework for quality and compatibility, including:

• ASTM B209 / B209M: Specification for Aluminum and Aluminum-Alloy Sheet and Plate, outlining base material requirements.
• ASTM B666 / B666M: Practice for Identification Marking of Aluminum and Magnesium Products, ensuring proper traceability.
• ANSI H35.2 / H35.2M: Dimensional Tolerances for Aluminum Mill Products, covering allowed variances in product dimensions.

By adhering to ASTM B744/B744M and its related standards, project stakeholders achieve consistency, safety, and quality in their use of corrugated aluminum pipe materials, facilitating approval and performance in a variety of critical civil and environmental engineering applications.
