INTRODUCTION
As a petroleum manager, you will be required to oversee the minor repair
of terminal equipment. It is in your best interest to know the proper
procedures and reference material available to you. You will also be
responsible for managing the on the job training (OJT) of newly assigned
personnel. The more knowledgeable you are in the area of equipment
repair, the more effective your training program will be. You will also
be responsible for knowing the manifold system within the petroleum
terminal. Until bulk petroleum products are issued for consumption from
the terminal they must first be received and stored in storage facilities
of varying capacities. All facilities have a common feature that allows
control of the products entering, leaving and transferring within the
system: This control feature is the manifold.
PART A - TYPES OF PIPE AND COUPLINGS
Lightweight Steel Tubing - Lightweight Steel Tubing is made of light
gage steel with API STD (standard) 5L pipe nipples welded to each end.
This tubing is furnished in 20-foot sections in 4-, 6-, 8-, and 12-
inch nominal sizes. Lightweight steel tubing is normally used in long
stretches of cross-country pipeline due to greater ease of handling,
and because under this condition it will experience only normal
operating pressures. Due to its thin wall, the pipe is not to be
buried nor is it to be used for submerged stream crossings.
API S&D 5L Pipe - API S&D 5L Pipe has a thicker wall than the
lightweight steel tubing pipe and is furnished in 4-, 6-, 8-, 12-, 16-
, and 20-inch nominal sizes. It is furnished in 20-foot sections
grooved for coupling and is beveled for welding in random lengths. It
is used at critical points and high pressure areas such as downhill
slopes, manifold areas, and pup joints.
"Victaulic" Couplings - "Victaulic" couplings are used to join the
lightweight steel tubing and API S&D 5L pipe sections together.
"Victaulic" is a trade name associated with the couplings which
consist of two housing segments, two bolts and nuts, and a synthetic-
rubber, oil-resistant, self-sealing gasket. The coupling and gasket
are designed so that the pipe joint seals under pressure and vacuum.
The coupling also provides a sufficient amount of angular deflection
and slack adjustment for expansion and contraction of the line between
adjacent joints. The gasket used with the coupling should be greased
to prevent pinching or sticking of the gasket.
Aluminum Pipe - Aluminum pipe is a new type of pipe being evaluated
for future use by the Army. It is lightweight, yet meets static and
dynamic pressure requirements of the fuel systems. This pipe has
fewer corrosion problems and is available in 19-foot sections. It is
used in locations similar to the lightweight steel tubing and API STD
5L pipe. High-pressure situations are corrected by the use of
pressure reduction stations. Maximum deflection (4,) is determined
using the device shown in the slide.
"Labarge" Snap Lock Couplings - "Labarge" snap lock couplings are one
of two types of couplings being evaluated for use with aluminum pipe.
"Labarge" is a trade name associated with the couplings. The Labarge
