Gate Rubber Seals



Useful information

FOR DESIGNERS

1) Our SBR composite seals feature excellent mechanical properties,

meeting the requirement to withstand ozone attack and featuring

better water absorption characteristics than those provided by

polychloroprene compounds.

The use of polychloroprene specification should be restricted to special

conditions:

a) Regions with high U.V. rays incidence and environments with high

ozone concentration.

b) The effect of environmental aggressive factors, such as certain

chemicals, not usually occurring in clean river waters (chemicals for

instances).

2) In some cases, not even SBR or CR will be adequate to the

environment where gates are installed (for instance, radiations or an

acid medium). Our technicians will indicate the proper elastomer for

each specific case.

3) Depending on project requirements, seal hardness properties other

than 50/60 Shore A and 60/70 Shore A hardness may be required

above or below standardized values.

Gate Rubber Seals



4) Refer to catalog and try to adapt your requirements to one of the

existing profiles.

In the event of minor changes having to be introduced in a given shape,

please contact our technicians.

This is highly recommended as tooling, in addition to high production costs

will demand a long manufacturing period.

5) Check that the selected shape is provided with the corresponding

corner (not all of them are).

6) Assess the need for using corner seals, or whether they could be

replaced with vulcanized splices at 45º.

7) Please refer to us regarding seals coated with a PTFE film, as not all

shapes in our catalog could be coated.

8) Pleases contact our technicians to request the development and

testing of non-existing shapes (see our bulletins).

9) Our seals are manufactured by the continuous molding process and,

therefore, will feature excellent mechanical and dimensional

characteristics, with minimum variations and with smooth surfaces.

Additionally, this process enables PTFE coatings to be applied.

FOR PURCHASERS

Our seals are made to order only and, therefore, please make sure your

orders will be placed with due advance notice to avoid delaying your

projects.

In order to expedite our reply to your quotation, please mention the code

number part or the dimensions of your selected shape, the type of rubber

(SBR, CR, or others), the required hardness (50/60, 60/70, or others) and

the span size.

Seals are always supplied with some excess length to enable them to be

adapted during assembly.

FOR USERS

1) Upon delivery of our seals to your premises, you will have to remove

them from their packaging and have them stored in a sheltered

place, away from direct sunlight, heat and moisture. Ideally, our seals

should be spread out for storage but, should this not be possible,

make sure the bending radius will be as large as possible less coiling

during storage. Nothing should be piled on top of our seals.

2) PTFE-coated seals should be carefully handled, never bending them

over in the direction of coating as this will lead to film wrinkling or

peeling. (see handling instructions).

Gate Rubber Seals



3) The use of our metal/rubber washers is recommended, particularly

whem installing sluice gate seals.

4) Our technicians will be available to assist you from the design stage

up to the maintenance of your sluice gates. If so requested, we will

be pleased to visit the power station to provide on-site assistance

and to help solving possible problems.

WARRANTY

Our Seals was awarded ISO 9001:2000 certification by Bureau Veritas.

Our seals are delivered together with a certificate of the tests performed on

the composite used.

Provided adequate conditions of transportation, handling and storage are

complied with, we will guarantee our seals for a period of 3 years counted

from the date they are shipped from our facilities.

External Aspect

Seals shall present uniform surfaces, free from defects capable of

jeopardizing the sealing function.

Splices shall be flawless, with a slight unlevelness being however admissible

between joined shapes, due to joint rubber contraction.

Gate Rubber Seals



Tolerance / Dimensional Check

Tolerances in the cross section dimensions of section shapes and seal

frame front end shall comply with ISO 3302, Class M3 (that superseded DIN

7715, Part 2, Class M3 standard).

The PTFE film shall present in the splice area a spacing to each other from 3

to 10 min; in that region, the film could show a slight unlevelness relative to

the section shape surface.
