1.0 Purpose
2.0 Description
1.0 PURPOSE
This manual is designed to provide the operator with
factory recommended operation and maintenance
instructions for safe and effective use of the TDW
PIG-SIG V Scraper Passage Indicator.
Read the entire manual for instructions on
installation, operation, and preventative maintenance
for the PIG-SIG V:
•On a plug assembly already set in a pipeline.
•On a line under pressure.
•On a line not under pressure.
2.0 DESCRIPTION
The TDW Scraper Passage Indicator is a device that
is installed on a pipeline to detect the passage of a
pig or sphere.
The PIG-SIG V indicator has a trigger that extends
into the pipeline through a welded fitting that has
been tapped. When a pig passes, the trigger is
tripped, activating the signaling mechanism.
Signaling mechanisms available include a flag
indicator, electrical indicator, and a combination flag
and electrical indicator. PIG-SIG V indicators are
interchangeable with all PIG-SIG indicators now in
the field. This makes it possible to use these units as
conversion kits as well as complete PIG-SIG
indicators. The PIG-SIG V indicator is weather-proof,
corrosion-resistant and the flag indicator offers high
visibility. All parts of the standard PIG-SIG V
construction are manufactured from stainless steel.

Section II – Introduction
2.0 Continued The PIG-SIG V Plug Assembly can be installed on or
removed from a pressure pipeline using a TDW T-
101 series Drilling Machine and accessories. In some
cases, a T-101 XL drilling machine may be required.
This manual addresses the T-101b and T-101b XL.
The PIG-SIG V indicator is available in various
combinations of operation, indication and materials of
construction, depending on piping requirements
including:
•All PIG-SIG V units are omni-dimensional.
•Flag indicator with manual reset flag (see Table
1).
•Electrical indicator with auto reset (see Table
2).
•Combination electrical auto reset with manual
reset flag indicator (see Table 3).
•Indicator extensions from one to ten feet.
•Flanged mounting.
•Because of stainless steel construction, any
model is suitable for environmentally harsh
conditions.
Table 1 shows the components of the manual reset
flag indicator model. Table 2 shows the components
of the electrical indicator with auto reset. Table 3
shows the components of the combination model
featuring electrical auto reset with manual reset flag
indicator.

Section II – Introduction
2.0 Continued Within each type, the PIG-SIG V indicator is available
in a number of variations, including such options as
O-ring material and material used in plug
construction. A number of extension lengths up to 10
feet are available to elevate the indicator.
The PIG-SIG V indicator can be installed on a line
under pressure, without taking the line out of service,
using the TDW T-101, T-101a or T-101b (or XL
versions) drilling machine.

Section III –Pipeline Not Under Pressure
Section III
Overview This section provides instructions for the installation
of the TDW PIG-SIG V Scraper Passage Indicator in
pipelines or pig traps not under pressure and where
there is no product flow.
A THREAD-O-RING nipple may be installed over a
pre-cut opening in the pipe. As an option to installing
the nipple over a pre-cut opening, the opening may
be cut using a drilling machine with a 1-7/16-inch drill
after the nipple has been welded to the pipe. Once a
nipple has been welded to the pipe, it is
recommended that a drilling machine be used to cut
the opening in the pipe wall so that the nipple will act
as a guide and ensure proper alignment. The
opening through the pipe wall must be 1-7/16- to 1-
1/2-inch diameter, and the bore of the nipple must be
coaxial with the hole cut in the pipe to within 1/64-
inch. No part of a THREAD-O-RING nipple may
extend inside the pipe for reinforcement or for any
other purpose. If additional reinforcement is required,
THREAD-O-RING nipples can be provided for
attachment to various types of integrally-reinforced
connections.
If the PIG-SIG V indicator is replacing a PIG-SIG IV
assembly, remove all PIG-SIG IV components.
