Patent FR-2610606-A1 (FR)
Title: Method of fitting the secondary seal of a tank with a floating roof
Inventor: DUCOS C
IPC: B65D88/50
Filed: 1987-02-06
Abstract: The invention relates to a method making it possible to avoid the downward turning-over of the secondary seal during the functioning of the floating roof. It uses a "seal-holder" 1 having a part which is inclined with respect to the horizontal at an angle of about 30 DEG . The secondary seal 3 is fixed to this "seal-holder" and, because of the inclination which is thus imposed on it, keeps the external edge constantly curved upwards. The method provides the way of making the "seal-holder" 1 from two simple elements, one of them being in the shape of a truncated cone 10 and the other being cylindrical 11, and uses gussets 9 facilitating the welding together of these elements 10 and 11. The method is particularly adapted to obtain both a good fluid-tightness with respect to evaporation of the stored product and with respect to infiltration of rainwater.
