Due to the nature of sealants and/or the exact application, it is possible for a leak to redevelop over time.

As such, the PLIDCO Flange+Repair Ring should be considered a temporary repair. If a leak does

develop, additional sealant may have to be injected into the PLIDCO Flange+Repair Ring. For this

reason, PLIDCO cautions the end user against using a PLIDCO Flange+Repair Ring for a buried, sub-

sea, or any other installation in which subsequent access is not feasible.

PLIDCO Flange+Repair Ring should be stored in a dry environment to prevent any unpainted surfaces

from rusting. Storage temperatures should be between 32°F(0°C) & 120°F(49°C). Cover with dark

polyethylene to keep direct sunlight from the seal material. It is best to exclude contamination, light,

ozone and radiation. Improper storage can cause the seal material to become cracked and brittle and

lose its ability to seal.

PLIDCO Flange+Repair Ring, as most PLIDCO products, have a unique serial number by which the

fitting is fully traceable. Additionally, all elastomer seals have a unique batch number by which the seal

material is traceable.

This warning is only applicable to a non-leaking, underwater injection. When assembling a PLIDCO

product under water (or under any liquid) it is possible to build up thousands of pounds of pressure in the

annulus between the PLIDCO Flange+Repair Ring and the flanges.

compressing the fluid trapped in the annulus as the two PLIDCO Flange+Repair Ring halves are closed

and tightened. For injections over a leak, pressure in the annulus equalizes with the pressure in the pipe.

The pressure trapped in the annulus may have the following effects:

• The pressure rating of the split product is exceeded causing leakage or damage to the PLIDCO

Flange+Repair Ring.

• The flanges on which the PLIDCO Flange+Repair Ring is installed are damaged.

• Personal injury or death due to subsequent removal of a vent plug.

The Pipe Line Development Company strongly recommends that all sealant injection ports are open

during installation for all underwater injection applications.
