Enbridge has also been a leader among oil and gas pipeline companies in integrating renewable energy assets. Their modernization projects often involve replacing aging infrastructure with advanced, sensor-equipped pipelines that utilize high-grade Geschweißte Rohre/Rohre technology to ensure leak-free operations.

4. Gazprom (Russia)

While often categorized as an integrated energy company, Gazprom’s gas transmission system is the largest in the world, spanning over 175,000 kilometers within Russia alone. This network is pivotal for domestic supply and export. The company’s engineering feats include underwater pipelines that require specialized materials capable of resisting high hydrostatic pressure and saltwater corrosion.

Gazprom’s operations heavily rely on high-diameter pipes and complex compression stations. The maintenance of this grid involves constant upgrades using precision-engineered components, such as Edelstahl-Rohrverschraubungen, to handle the immense throughput of natural gas.

5. Kinder Morgan (USA)

Kinder Morgan owns an interest in or operates approximately 83,000 miles of pipelines and 140 terminals. Their pipelines transport natural gas, refined petroleum products, crude oil, carbon dioxide (CO2), and more. They are the largest natural gas terminal operator and independent transporter of petroleum products in North America.

A key differentiator for Kinder Morgan is their CO2 pipeline network, which is used for Enhanced Oil Recovery (EOR). Transporting supercritical CO2 requires pipelines with specific metallurgical properties to prevent corrosion, highlighting the importance of sourcing from top-tier manufacturers of Nickel Alloy Bar/Rod and tubing.

6. TC Energy Corporation

Formerly TransCanada, TC Energy is a major player with a network of over 93,000 kilometers of natural gas pipelines. They supply more than 25% of the clean-burning natural gas consumed daily across North America. Their Keystone Pipeline system (distinct from the cancelled XL project phases) continues to be a vital conduit for Canadian crude reaching US refineries.

TC Energy is aggressive in its adoption of safety technologies. They utilize smart pigs (pipeline inspection gauges) that run through Nahtlose Rohre/Rohre sections to detect microscopic fractures before they become failures.

7. Energy Transfer LP

Energy Transfer boasts a diverse portfolio of energy assets, including one of the largest intrastate and interstate pipeline networks in the United States. Their assets span nearly 120,000 miles, moving crude oil, natural gas, NGLs (Natural Gas Liquids), and refined products.
