When Should Procurement Managers Procure Pipes? 

Procurement managers in industries like oil & gas, irrigation, and energy frequently encounter a pivotal choice: replacing existing pipes or procuring new ones. This decision requires careful analysis of performance metrics, industry needs, and cost implications.  

This decision hinges on understanding performance metrics, industry requirements, and cost-effectiveness. The first step is identifying the right time to act. Pipes need replacement or procurement in the following scenarios: 

• Existing infrastructure shows signs of reduced performance. 

• Task requirements evolve due to industry advancements or regulatory changes. 

• The technology used in current pipes becomes obsolete. 

Purchasing New Pipes 

When procuring new pipes, procurement managers should collaborate closely with planning engineers and reference the Bill of Quantities (BoQ) to align with project requirements. Key considerations include: 

1. Brand and Specifications: Choose pipes that adhere to specific ASTM codes or international standards. 

1. Material Types: 

1. Metallic Pipes: Ferrous (e.g., steel) or non-ferrous (e.g., copper, aluminum). 

1. Non-Metallic Pipes: PVC, HDPE, or composite materials. 

Matching these specifications ensures the pipes meet the demands of EPC infrastructure projects and industrial applications. 

Deciding to Replace Existing Pipes 

Replacing pipes is necessary when performance and efficiency no longer meet operational requirements. Factors to evaluate include: 

1. Reduced Performance: Diminished flow rate, leaks, or corrosion. 

1. Altered Task Requirements: Changes in pressure handling, temperature resistance, or flow capacity. 

1. Obsolescence of Technology: Older pipes may not support modern operational needs or compliance requirements. 

Procurement managers must rely on metrics like the Equivalent Uniform Annual Worth (EUAW) to decide whether to replace or retain a pipe. 

Understanding the EUAW Curve Over Time 

The Equivalent Uniform Annual Worth (EUAW) metric evaluates a pipeline’s economic value throughout its lifecycle, assisting managers in balancing operational reliability and cost efficiency. 

1. Initial Ownership Costs: Decrease over time as initial investments depreciate. 

1. Annual Operations and Maintenance (O&M) Costs: Increase with aging infrastructure due to repairs and inefficiencies. 

1. Salvage Value: Declines as the pipe reaches the end of its usable life. 

Analyzing the EUAW curve empowers managers to make data-driven decisions, optimizing cost efficiency while maintaining operational dependability. 

Case Study: Evaluating Pipe Replacement 

Problem Statement: 
A pipeline in an energy project has been in service for three years, with an EUAW of Rs. 5,210 per year and a remaining life of five years. A replacement option has the following parameters: 

• First Cost: Rs. 25,000 

• Salvage Value: Rs. 3,800 

• Life Span: 12 years 

• Annual Operating Cost: Rs. 720 

Analysis: 
Using a 10% Minimum Attractive Rate of Return (MARR), calculate the EUAW for the existing and replacement pipes: 

1. EUAW of Existing Pipe (EUAWD): Rs. 5,210 

1. EUAW of New Pipe (EUAWC): 

1. Rs. 25,000(A/P, 10%, 12) + Rs. 720 – Rs. 3,800(A/F, 10%, 12) 

1. Result: EUAWC = Rs. 4,211 

Decision: 
Since the EUAW of the replacement (Rs. 4,211) is lower than the current pipe’s EUAW (Rs. 5,210), the new pipe should be purchased. 

Procure New Pipes for your Next Pipe Replacement Project 

Strategic pipe procurement is a vital responsibility for procurement managers in industries like oil & gas, manufacturing, and water management. Informed decisions drive efficiency and sustainability.  

Decisions should be driven by technical specifications, cost analyses like EUAW, and long-term performance needs.
