Trans-Alaska-Pipeline

How do you extend the Winter?

Schmöle delivers finned tubes for the Trans-Alaska-Pipeline.

At 1300 kilometres the Trans-Alaska pipeline is not the longest in the world, but is probably one of the most technically demanding. It was built on stilts for about half of its length in order to prevent the pipeline sinking during the melting of the permafrost. Meanwhile, however, climate change has resulted in ever more warmer weather periods, so much so that the soil has to be artificially frozen for approximately four to six weeks of the year. Schmöle finned tubes made of titanium were used for this task under the most extreme conditions. Although the material is very expensive it is also so durable that its use in comparison to other materials is highly cost effective. Other materials would in fact have to be renewed regularly under the prevailing extreme conditions causing expensive maintenance measures.
