Home > Welded Pipes > High-Pressure Service
High-pressure pipelines operate under elevated internal pressure, rapid pressure fluctuations, vibration, pulsation, and demanding mechanical loads. These pipelines carry steam, hot water, hydrocarbons, feed liquids, compressed gases, and high-pressure utilities across refineries, power plants, petrochemical units, and industrial facilities.
A672 CC60 / CC65 Electric Fusion Welded (EFW) Pipes are specifically engineered for high-pressure service. Manufactured using Class C configurations with a range of supplementary requirements, these pipes offer:
A672 pipes combine heavy-wall welded construction with controlled heat treatment, making them ideal for high-pressure pipelines requiring long-duration safety and structural reliability.
High-pressure service refers to environments where pipes are subjected to:
A672 CC60/CC65 welded pipes are built to withstand these conditions with:
✔ High tensile strength
✔ Secure welded joints (EFW)
✔ Controlled microstructure
✔ Stable welding quality under ASME/ASTM code
✔ Excellent toughness even under fluctuating pressure
High-pressure lines often require:
A672 welded pipes satisfy all these requirements while providing cost-effective, high-strength pressure pipeline solutions.
A672 CC60 / CC65 welded pipes are used in:
These applications require maximum pressure containment reliability.
High-pressure welded pipes must maintain structural integrity during operation while resisting pressure spikes, temperature variations, and mechanical stresses.
