The P-TB-01 is a liquid filled seal from ATECO and should be compared with the P-TB-00. The full range of floating roof tank sizes can be serviced and service in crude oil and diverse refined products is commonplace. Aromatics contents of up to 75% or 100% can be handled. The tube diameter can also be varied to meet a range of rim gap dimensions.
The P-TB-01 seal is similar to the P-TB-00 seal but has an additional component, an inner tube, and also differences in the metal support arrangements.
Against the tank shell there is a scuffband of nylon fabric coated with an abrasion resistant polymer coating which presents a ribbed surface to the shell. The scuffband is attached top and bottom by bolting in such a fashion that the lower portion of the scuffband is in contact with the stored liquid, ie. product mounted.
Between the scuffband and the roof rim a tube of flexible polymer is inserted and filled with either kerosene or, if the local climate is clement, a water/glycol mixture.
The filled tube exerts a hydraulic pressure outwards, holding the scuffband against the tank shell and so effecting a seal.
The scuffband and tube for this seal are supplied open ended which simplifies construction (no guidepoles or rolling ladders etc. to negotiate).
ATECO Tank Engineering seals meet or exceed the allowable gap requirements set forth by the governmental and regulatory agencies throughout the universe. This design will show superior sealing ability throughout the roof travel; accounting for roof shifting, out of roundness, buckling, and the expansion and contraction requirement of each tank.
ATECO TANK warrants its seals to be free from defects in the material and workmanship for a period of two year. Our liability under any express or implied warranty is limited to the purchaser price of any part found defective. Any seal systems installed by ATECO TANK TECHNOLOGY ENGINEERING SERVICE will have an additional two-year warranty.
