External floating roof and internal floating roof. As a result without intending to they took the roof off float. Altech aluminum internal floating roofs are custom design to each individual tank within the requirements of api 650 appendix h.

Each altech ifr will have negotiating devices for fixed internal tank components such as roof support columns gauge pipes or ladders which penetrate the ifr. An external floating roof tank is a storage tank commonly used to store large quantities of petroleum products such as crude oil or condensate.

Floating roof tank is that which the roof floats directly on. This type of internal floating roof tank design is incredibly immune to solid winds so is optimal for high wind or cyclone vulnerable locations. These devices will provide clearance of at least 4 1 2 between the tank component and the structure of the ifr. That means internal floating roof tanks have two roofs one that floats over the liquid and another which covers the top of the tank.

Bonnet roofing systems are basically a mansard roof backwards. Storagetech storage tank internal floating roofs storagetech has been proudly innovating designing manufactiring and installing external and internal pon.
