Floating roof drain systems
They are meant to carry off stagnant water from the floating roofs of storage tanks (oil and gas industry).
These pipe constructions consisting of articulated connections are suitable for immersed industrial applications in storage tanks.
They are made of several TP1100S rotating unions (more information: www.raccordtournant-pacquet.com)
As they are of rigid constitution, they allow more resistance in the long run and are used as a substitute to ordinary flexible hoses when required by the working environment.
