GENERAL INFORMATION
1.01 What
is the purpose of FMP conduit? How will it benefit you to use it? Where
is it used? These are a few of the questions addressed in this guide.
This reference guide was designed to help familiarize installers, inspectors,
line crews, construction supervisors, engineers, etc. with the FMP -
Flanged Maintenance Pipe systems and provide some helpful installation
tips. These recommendations have come from first hand experiences with
maintenance contractors, supervisors, etc. around the country.
1.02 This guide
was written specifically for 4" 10 ga. FMP. Other sizes and thicknesses
are available. See the catalog for complete information.

If you need assistance with project plans you may also fax your questions
or plans to 614-794-3760.

CONCEPT
2.01 Compared
to placing a 4-inch split hinged steel product or a field fabricated
split steel conduit, the FMP-4 is an engineered raceway system that
offers more room inside for your inner-ducts and fiber optics cables
with less work and less money required. FMP-4 provides an inside diameter
of 4.5 inches and weighs only 8.4 pounds per foot and needs no couplings
for assembly or special terminators. The system is a significant cost
and labor saving system to be used where there is a requirement for
mechanical protection in an existing underground duct or direct buried
cable system.
2.02 The FMP-4
system is constructed of rugged 10 gauge steel (galvanized or black
steel pipe), so field splices are easily made with a standard ½”
wrench, a cordless drill, 3/8” drill bits, cutoff saw and terminates
to standard IPS conduit sizes. Leave your welder, special adapters (usually
plastic) and pipe threader at the shop.
2.03 FMP Systems
are the most versatile repair/protection system available on the market
today. Although this manual will focus on the four-inch system this
system is also available in sizes 2 inch through 6 inch and we will
provide larger sizes at the customer's request.

DESCRIPTION
3.01 The
FMP System in this example is constructed of 10-gauge steel. The individual pieces are
relatively lightweight which makes it easy to handle in the field but
it provides excellent protection. One-inch flanges provide added strength
and when properly assembled provides a tight seal. FMP is assembled
with stainless steel nuts and bolts reducing corrosion and ease of re-entry
at a later date. Slotted holes are set every three inches on center to facilitate cutting and fitting. (See Pictures 03 and 04)
3.02 Primary uses
are: buried maintenance applications, temporary and emergency cable
protection.

INSTALLATION
4.01
The FMP system is shipped in halves 10 foot long and supplied
with an appropriate number of stainless steel nuts and bolts.
Each piece of the system has 1" slotted holes every three inches so that
you may cut where needed to start a joint stagger without having to drill a new hole.
(See Pictures 03 & 08) When measuring, your cut should be
marked at 1.5 inches on center of punched hole on either side.
Pre-cut, 5'- 0" long pieces are available.
4.02 After
exposing and repairing your cable system, simply slide one half
the FMP system in complete length of your desired area of protection.
Next take your cut to size piece prepared earlier and align at the
start of your project and continue to the end with full-length
pieces until you arrive at the termination.

TRANSITIONS & TERMINATIONS 
Picture 06 - Bends
5.01 Transitions
or sweeps are available in 90, 45 and 30-degree angle and 24" radius.
5.02 The
sweeps are manufactured to the same specifications as the straight length.
Supplied in two pieces.
5.03 As you field
measure your transition you simply complete your joint stagger to a
flush 90- degree finish. This will prepare the split conduit system
for your Rotation Coupler which gives you the ability to rotate around a full 360
degrees.
5.04 Man-Hole
Termination
Examine manhole termination and place a 4" Rotation Coupler for
a uniform connection inside the manhole. Follow instruction 5.07 for
termination to existing four-inch conduit. (See Picture 07)
5.05 Termination
to existing four-inch conduit
As you approach the end or start at a manhole stub out or simply need
to reconnect to existing conduit, be sure to encase this in the same
manner as your exposed inner-ducts and cables. No need for any special
fittings or adapters.

SUMMARY
We hope this
guide is helpful to you whether you order the product, install, design
or inspect. This product is a direct result of bringing great ideas
from the field to enhance quality, production in the field and reduce
overall cost of system and installation. If you have any unanswered
questions regarding the FMP system or questions about specific applications,
your call is welcomed.
