Q1: What are composite line pipes?
A1: Pipes with fiber-reinforced polymer (FRP) layers over steel. Benefits:
50% lighter than steel
Corrosion-free
Used in CO₂ transport and rehab
Q2: How is additive manufacturing (3D printing) used in pipelines?
A2: Applications:
Custom fittings/clamps
Repair of corroded sections
Prototyping new alloys
Limited to small diameters currently
Q3: What are smart pipelines?
A3: Pipelines embedded with sensors for:
Real-time strain monitoring
Leak detection via acoustic fibers
Predictive maintenance using AI
Q4: How will hydrogen pipelines differ from natural gas lines?
A4: Key differences:
Higher-grade steels (X52+) to prevent hydrogen embrittlement
Specialized compressors
More frequent inspections
Permeation-resistant coatings
Q5: What is the role of robotics in pipeline maintenance?
A5: Robots perform:
Internal welding/coating repairs
Crack sealing with polymers
Ultrasonic mapping via crawlers
Reduce human entry in hazardous spaces
