Gasket Tape Series 1000

Installation

Installation Instructions

ATTENTION

When installing GORE

Gasket Tape Series

1000 in joints with multiple (2 or more)

gaskets compressed with a single set of

bolts or clamps, see the installation

supplement, “Installation on Joints with

Multiple Gaskets,” for additional mandatory

nstructions.

1. Size Selection

1.1 Gasket Width

Select the gasket width that provides

enough material to align the gasket

tape ﬂush with the inner and outer

diameter. Ensure full coverage of the

glass surface. Excess material may

exceed the outer diameter.

1.2 Gasket Thickness

Most applications require a base

layer of 6 mm (1/4") tape, which can

accommodate deviation up to 1.5 mm

(1/16") without shimming. Applications

with deviation up to 2.3 mm (0.090")

can utilize 9 mm (3/8") tape without

shimming.

1.3 Shimming

To effectively seal ﬂanges with devia-

tions beyond the maximum for the

base layer, a shimming process is

recommended. Use of 3 mm (1/8")

GORE

Series 1000 s

him tape as a shim

layer will accommodate an additional

1.5 mm (1/16") of ﬂange deviation.

Ensure the shim layer has the same

width as the base layer.

2. Installation

2.1 Open Flanged Connection

For a trouble-free installation, open

the ﬂanges a minimum of 15 cm (6").

Ensure the ﬂanges are well secured

for a safe working environment.

2.2 Clean Sealing Surface Thoroughly

To ensure optimal adhesion, remove all

oil, graphite, and/or other residue, prefer-

ably using a specialized grease remover.

2.3 Measure Flange Irregularities

Place a separator between the ﬂanges to

avoid glass-to-glass contact. A ﬁber

sheet or a plywood board may be used

to achieve this. Close and align the

ﬂanges without compressive load

beyond equipment weight. Use a thick-

ness gauge to measure the irregularities

or ﬂange deviations. Mark all irregulari

ties and their magnitude on the ﬂange

for

later reference. Be sure to mark the

ﬂange orientiation for future ﬂange

alignment. For the shimming process,

please refer to 2.7.

2.4 Perform Initial Skive Cut

Unwind about 0.5 m (1.5 ft) of GORE

Gasket Tape Series 1000. Cut the end

with a sharp knife on a clean, ﬁrm sur-

face using the skiving technique (Fig. 2).

The length of the skive cut, l

, should

match the dimension in table 1.

The skive angle is < 10°.

ATTENTION

When using the skiving technique to cut the

gasket tape, it is critical that the skive runs

out smoothly, avoiding any step.

Figure 1

2.5 Apply Base Layer of Gasket Tape

Position the skived end of the gasket

tape at a location where no shimming

is needed, thus at a place where both

ﬂanges touch (see 2.3). Begin near the

designated starting clamp or bolt.

Remove the adhesive backing as it is

installed, to prevent the the adhesive

strip from picking up dirt during the

installation.

ATTENTION

The adhesive on GORE

Gasket Tape Series

1000 adheres best to clean surfaces.

In cold conditions, gently warm the gasket

tape before installation.

2.6 Complete the Layer of Gasket Tape

Complete the gasket by laying the tape

over the skived end, extending beyond

~15 mm (1/2"). To prepare for the

second and ﬁnal skive cut, identify

and mark the starting and end points.

Cut away the gasket material at an angle,

so that the maximum height, h, matches

the dimension in table 1. This will

leave the tallest section of the skive

~1/3 thicker than the original gasket.

ATTENTION

Avoid contact with oil and grease when

handling and installing the gasket tape.

No additional

anti-adhesives spray or liquid

should be applied to the ﬂange surfaces.

2.7 Shim Flange Irregularities

Using the measurements performed in Step 2.3, use the 3 mm (1/8") GORE

Series 1000

shim tape to perform the following shimming process.

a) Measure the length of the irregularity to be shimmed.

b) Cut the gasket tape approximately 4 cm (1 1/2") longer than the measurement.

c) Cut both ends of the gasket tape shim using the skiving technique described in

Step 2.4.

d) Place the gasket tape shim on the previous layer of GORE

Gasket Tape Series 1000.

e) Repeat steps a) through d) until the number of shims have been installed for the

measured irregularity.

Note: for both base layer thicknesses, add one shim layer per 1.5 mm (0.060”) additional deviation.

ATTENTION

Ensure the skive cut begins right after the marked ﬂange irregularity. Full shim layers should

be built to accommodate the ﬂange deviation for even compression of the GORE

Gasket Tape

Series 1000.

3. Torquing

3.1 Select a Torque

The torque recommendations of the

equipment manufacturer must be

followed at all times.

3.2 Close the Flanged Connection

Bring the ﬂanges in contact and align

ﬂanges as marked in Step 2.3. If many

shim layers are causing uneven contact,

precompress the shimmed layers by

slightly tightening the bolts/clamps

directly near the thick gasket spot.

3.3 Torque

Utilize the star pattern, multiple pass,

and incremental torque. Refer to the

ESA/FSA “Gasket Installation Proce-

dures”

for more detailed information

on the recommended installation

practices.

3.4 Retorque

It is recommended that the bolts/

clamps

are retorqued once after the ﬁrst

temperature cycle. A temperature cycle

is deﬁned as an internal temperature

difference (∆T) greater than 100 °C

(180 °F ) for at least 1 hour.

Be sure the retorque is in accordance

with the torque value recommended

by the equipment manufacturer.

Retorquing should only be performed

after the ﬂange has cooled down to

ambient temperature.
