BOA Group LNG Transport

Oil & Gas Transport

BOA expansion joints secure the transport of Liquefied Natural Gas (LNG).

Natural gas accounts for one-fourth of all energy consumed worldwide. Liquefied Natural Gas is transported around the world in large vessels, especially designed for this purpose. Expansion joints for these applications are a specialty of the BOA Group.

Due to the extreme operating circumstances (high pressures) and the safety risks that go with it, these expansion joints must meet the highest demands on design, manufacturing, and quality.

The products manufactured by the BOA Group hold all necessary certifications and approvals.

BOA has developed specific convolution profiles in order to supply the LNG tankers with the products most suited to the demanding working conditions.

Omega ZH profile

The Omega ZH profile offers high pressure resistance while still providing a high life cycle.

U shape

The U shape profile with high corrugations is particularly suited to low-pressure and high life cycles.
