SUSPENDED DECK FOR LIQUID NATURAL GAS TANK

摘要

A non-welded deck used to support insulation from the roof of a low temperature or cryogenic storage tank is disclosed. The deck may be comprised of a plurality of spaced apart bars with metal sheets covering the spaces between the bars. The edge of the metal sheets may be clamped to the bars to form the deck. The edges of adjacent metal sheets may overlap and be clamped together in such a way as to deform the sheets creating a metal-to-metal vapor and dust proof seal. The plurality of clamping bars and support bars may secure the metal sheets with sufficient strength to allow the entire deck to support loadings as a stressed membrane. The tank may be constructed with hardware that remains secure even after being subjected to repeated thermal cycling of over 200° Celsius (360° Fahrenheit).
