ATS-TS1 Tube Seal– The tube containing compatible liquid is covered by a scuffband and locatd directly on the sotred product. The liquid filled tube gives pressure softly to the tank shell and eliminates the space between the stored product and seal. Against the tank shell is a scuffband of nylon fabric coated with an abrasion resistant polymer coating which prevents a ribbed surface to the shell. The scuffband is sttached at top and botton by bolting in such a fashion that the lower portion of the scuffband is in contact with the stored liquid, i.e., product mounted. The filled tube exerts a hydraulic pressure outwardsm holding the scuffband against the tank shell and so effecting a seal.
