CTS1 Scissor shoe plate seal
The CTS1 is a well-designed scissor type shoe plate seal. The shoe plates, that generate the sealing are attached
to the floating roof with hangers and the sealing force is generated by tensioners. All our shoe plate seals are custom
designed for each tank they will be fitted on, which eliminates problems that are common with off-the–shelf types of seals.
The tank-specific design ensures a seal with a superior gap control over traditional scissor seal designs.
Both the seal design as well as the individual attention for each seal will make sure that the seal will be able to deal with both the stored product as well as
with the particular dimensional properties and design aspects of the tank involved
CTS1 Scissor Product Features:
- excellent vapour tightness, resulting in maximum emission reduction
- eliminates much of the rain water ingress to the stored product
- compatible with all stored products, including 100% aromatics
- available in different material combinations,
- suitable for both vertical and horizontal roof rims, without rim modifications
- service life expectation in excess of 30 years
- custom designed for each specific tank
- easy installation, reduction of up to 50%
- liquid mounted seal
- full installation manuals and project support available
- excellent gap control due to tensioner placement
- complies with EPA and API standards
- successfully used by many major oil and tank storage companies
- suitable for both welded and riveted tank shells
- can be combined with all known secondary seal designs

Scissor seal design:
When designing a scissor seal many aspects contribute to the functioning of the seal. Our specialist engineers consider all relevant design aspects to generate a seal with superior sealing characteristics and a very long service life
|
Design and engineering
CTS designs each individual seal for the tank it will be fitted on.
This will prevent the installation of a standard seal, where it is
possible to find out within months that this standard seal would
not be able to deal with the actual rim gap or tank conditions.
A detailed tank inspection sheet will facilitate our engineering
process. Delivery will include an as-built drawing for the supplied
tank seal as well
Installation
CTS is capable of installing any seal on your
tank, but our extensive drawings and installation
manuals will facilitate you to have either your
own or contractor staff install the seal and, if
applicable, the integral foam dam as well. The
advantage of having your own (contractor) staff
installing the system could be significant, reducing
travelling and lodging costs. Experienced CTS supervision
is available upon request.

Materials, selection
Not just the design of the seal is
important for its performance. Correct material
selection might be even more important to
ensure a long term adequate performance for any
seal. In this respect one also has to realise
that fabrics will be difficult to inspect and
malfunctioning seals could represent a hazard,
while still mechanically sound. Materials have
to withstand the stored product, ozone, sun
exposure and rain water contact. CTS is able
to give you a profound advise on the optimal
combination of materials, resulting in an economic
seal design able to deal with the harshest
conditions. Seals can be manufactured in a wide
variety of materials, including different grades
of stainless steel and polymer materials. This will
make our seals suitable for processes with 100% aromatics or
aggressive chemicals. |
