Common Pitfalls When Sourcing Culvert Corrugated Pipe (Quality and Intellectual Property)

Sourcing culvert corrugated pipe involves more than just cost and delivery considerations—quality assurance and intellectual property (IP) protection are critical factors often overlooked. Failing to address these areas can result in project delays, safety hazards, financial losses, and legal complications. Below are the most common pitfalls to avoid.

Poor Quality Control and Non-Compliant Materials

One of the biggest risks when sourcing corrugated metal or HDPE pipes is receiving substandard products that fail to meet required engineering or regulatory standards (e.g., AASHTO, ASTM, or local codes). Common quality issues include:

• Inconsistent wall thickness
• Incorrect corrugation profile or depth
• Use of recycled or low-grade steel/plastic
• Inadequate corrosion protection (e.g., insufficient galvanization or coating)

These flaws can lead to premature pipe failure, structural instability, and costly replacements. Always verify manufacturer certifications, request third-party test reports, and conduct site or factory inspections.

Lack of Traceability and Documentation

Many suppliers—particularly in international markets—fail to provide proper documentation such as mill test reports (MTRs), material certifications, or compliance statements. Without traceability, it’s difficult to prove that the pipe meets project specifications or to defend against liability if a failure occurs.

Ensure that every batch of pipe is accompanied by full documentation and that records are retained throughout the project lifecycle.

Counterfeit or Unlicensed Products

Some manufacturers produce pipes that mimic the design, branding, or performance claims of reputable patented systems without proper licensing. This is a serious IP infringement and can expose the buyer to legal liability.

For example, certain structural plate systems or high-performance HDPE profiles are protected by patents. Sourcing a “similar” product from an unauthorized manufacturer may violate IP rights and result in lawsuits or forced removal of installed materials.

Always verify whether the product design or manufacturing process is patented and confirm that the supplier has the necessary rights or licenses.

Inadequate Testing and Performance Validation

Some suppliers claim their pipes meet certain load ratings or service life expectations without providing validated test data. Relying on marketing materials instead of independent lab results can lead to underperforming installations.

Require third-party performance testing—such as deflection tests, long-term hydrostatic strength (for HDPE), or corrosion resistance evaluations—before finalizing procurement.

Ignoring Supply Chain Transparency

Complex global supply chains can obscure the true origin of materials. A pipe may be labeled as coming from a reputable manufacturer but is actually produced by an unqualified subcontractor or “ghost factory.”

Conduct due diligence on the supply chain, including site audits and supplier qualification programs, to ensure consistency and accountability.

Failure to Address IP in Contracts

Procurement contracts often neglect to include clauses related to intellectual property indemnification. Without these, the buyer may be held liable for using infringing products, even if unaware.

Include clear terms stating that the supplier warrants the product does not infringe any IP rights and agrees to defend against related claims.

By proactively managing quality and IP risks, project stakeholders can ensure the long-term success and legal compliance of culvert installations.
