Which is the Longest Cross-Country Oil Pipeline in the World?

Longest Oil Pipeliine of the World: It serves as a colossal industrial artery spanning thousands of miles across rugged terrain and international borders and fueling the economies of multiple nations. It is designed as a feat of mid 1990's engineering. This pipeline network transports millions of barrels of crude oil daily from deep within the Eurasian interior to the heart of Europe.

Which is the Longest Oil Pipeline in the World?

The Druzhba Pipeline of Russia is the longest cross-country oil pipeline in the world. It starts through Russia and passes through seven countries connecting Central- North Europe. The pipelines are the silent giants that power economies in the intricate world of global energy, The Druzhba Pipeline, often referred to as the Friendship Pipeline, holds the record as the longest cross-country oil pipeline in the world.

Countries Covered by the Longest Oil Pipeline in the World

The Druzhba network is a marvel of 1960s engineering that has remained vital in the present. It begins in Almetyevsk, Russia, where it collects crude oil from Western Siberia region and passes through the Urals Mountains and the Caspian Sea from there, it traverses a huge expanse before splitting in Belarus to serve two distinct regions includes:

Northern Branch:  where it travels through Belarus and Poland to reach refineries in Germany.

Southern Branch: here it crosses Ukraine to supply oil to Hungary, Slovakia, and the Czech Republic.

In total, the main system and its primary branches directly connect seven countries, though its secondary networks reach even further into the European continent. 

Note: 4,000 km refers to the main trunk line, while 5,500 km includes all secondary branches and extensions.

Although Russia’s Druzhba pipeline is the longest one, there are other following closely the longest Oil Pipeline in the world. Here is how the world's longest oil pipelines compare as of 2026:

Key Facts about the Longest Oil Pipeline in the World

Druzhba Pipeline has a strategic and massive impact on global energy security. Here are the some important facts about the World’s longest oil pipeline: 

• Druzhba Pipeline is capable of transporting between 1.2 to 1.4 million barrels of oil per day.

• The pipeline crossed 45 major rivers and over 200 railways and highways.

• It was constructed between 1960 and 1964. It was designed to provide the Soviet Union's allies with a reliable and cheap energy source.

• The pipeline remains a focal point of geopolitical tension despite its name Friendship pipeline. In recent years disruptions have been seen and shifts in usage as European nations seek to diversify their energy sources away from traditional routes.

• It is also know as the Friendship Moniker the name comes from the Russian word Druzhba (Дружба), symbolising the initial cooperation between the Eastern Bloc nations of USSR during the Cold War.

In the present time the Druzhba pipeline remains a testament to mid-century industrial ambition and engineering which continues to serve as a primary energy artery even as the world transitions toward a diversified energy landscape.
