PIPE COATINGS
For 100% corrosion and sealing protection of line pipe and field welds contact Capex Canada Inc.
Fusion bonded epoxy coatings applied internally or externally to steel pipe provide not only
protection against external corrosion for buried, exposed or submerged oil and gas pipelines but
also provide thermal insulation.
One of the common coatings: 3 LAYER PE coating
to specification DIN 30670
Additional applications that are available:
– Liquid 2-Part Epoxy
– Polyethylene
– PE
– Nylon
– Glass
– Concrete Lining
– Bitumen / Fiber
PC1
Pipeline field work contractors perform the following coating work:
– Field joint internal and external
– Fusion bonded epoxy
– Liquid 2- part epoxy
– Shrink sleeve applications
Heat shrinkable sleeves for corrosion protection of field welds are easily applied to
steel pipelines for both buried as well as exposed installations of various operating
temperatures. The recommended minimum sleeve width = bare steel dimension plus
two inches on either side of the pipe weld. Some of these sleeves provide excellent
resistance to cathodic disbandment resulting in effective long term corrosion rotection.
Heat shrinkable sleeves are available in three types:
– Wrap around sleeve
– Tubular
– Tape
Note – Fusion bonded epoxy powder as an alternate can also be applied as a
protective coating to the 'field' weld area.
Internal and External Fusion Bonded epoxy
(FBE) is factory applied to steel line pipe up
to 45 feet long.
The end to end corrosion protection is
completed during construction by
applying FBE Power to the internal and
external Field Hoist after welding –
onshore or offshore.

PLUGGING
The plugging operation provides a method to remove, and if necessary, replace
a section of a piping system without having a shutdown or flow interruption.

TAPPING
Both hot tapping and pressure tapping provide a method of making an
uninterrupted line flow connection while the existing system is under pressure.
Step One Attach a pressure containing fitting such as a
threadolet, weldolet or a threaded or flanged branch
connection such a split flanged tee to the existing
pressurized system.
Step Two Attach a gate or ball valve. The port through the
valve must be sufficient to allow the hole cutter to
pass through.
Step Three Test to verify the valve and fitting will withhold the
pressure of the system.
Step Four Cut the hole through the pipe wall and remove the
coupon so produced. Close valve, remove tapping
machine and install connecting pipe.

CROSSING MATERIALS
Sealing materials are available for the ends of cased crossings from Capex. Although
centring of the pipe in the casing is most desirable these seals are available for use in
any positioning of the pipe in relation to the casing and are held in place by steel clamps.
U-Seal and Z-Seal for cased Crossings
Typical Applications
Casing U-Seal
Pipeline
The flexible U-Seal is designed for eccentric
U-Seal
installations and maintains its seal regardless of
the pipe position in relation to the casing. Two
stainless-steel bands with adjustable double-
end clamps hold the U-Seal firmly in place. A Casing
screwdriver is the only tool needed for installa-
tion. the U-Seal will withstand temperatures to
235°F (112°C). The U-Seal can be installed
two ways. The top drawing
shows the “U” shape which
provides for ample flexibility. It
can also be installed with the
shorter band on the outside

an extra rugged seal is required. It is recom- Casing

CATHOD PROTECTION
Another crossing installation material from Capex are the cradles.
These cradles carry the weight of the pipe, and the backfill, and
also insulate the pipe from the casing. These cradles also center
the pipe inside the casing.

SEALING MATERIALS
Seal low pressure flange leaks in
chemical and steamlines with
materials from Capex without shut
down interruption of production
and costly unit removal to a distant
workshop with a permanent easily
applied mixture of only two
compounds plus a steel band.
The steel banding kit allows custom made seals
to be formed for each individual repair
RECOMMENDED FOR SERVICES
NOT EXCEEDING 300°C NOR 600 P.S.I.
For leaks in pipelines due to corrosion or accident Capex can solve this problem
with a sleeve wrap–around sheet material of such high strength which when
applied to any size of pipe actually exceeds the yield strength of the original pipe.
The Clock Spring System
consist of:
1. A patented, high-strength,
unidirectional composite
structure.
2. A patented, fast-curing,
high-performance two-part
adhesive system.
3. An extremely high
compressive strength,
proprietary load transferring
component. Once installed,
the three elements bond
together to form an
extraordinarily strong,
durable repair.

PIPE HANGERS
Some of our sources have over 50
years experience in the Power and
Petro Chemical Industries, and the
quality of their products is assured by
stringent quality control supervision
that design is in accordance with the
customer’s purchase order and at
least one of the following
specifications:
DIN; VGB; SVDB; BS 394
PARTI; KTA 320513; ANSI
B31-1; MSS SP58; MSS SP69;
ANSI SECTION III,
SUBSECTION NF.
The two most commonly used
hangers:
– the Constant
– the Spring
Both types of hangers bear the
weight of the pipe which undergoes
vertical movement.
Constant support hangers are used
in all cases in which the vertical
movement is relatively large.
Spring hangers are used in all
cases in which the vertical
movement is elatively small.

WELDING EQUIPMENT
WHICH IS AVAILABLE FROM CAPEX
CAPEX can supply welding rod/wire for mild steel, stainless steel, low
alloys, nickel alloys and exotic metals and brazing alloys to satisfy all
your maintenance and repair applications.
A complete line of spot, press, rocker arm, seam, wire, butt, flush
butt, as well as automatic and semi automatic welders are available.
The American Welding Society and other industrial sources have
estimated that the average welder has his ‘arc-on’ only 30 per cent of
the time. With attention to work flow some welding machines will
conservatively achieve a 70% ‘arc-on’ time.

MECHANICAL PIPING SYSTEM
The mechanical method is an alternate way of joining pipe rather than threading,
welding, or flanging pipe ends.
The mechanical method includes the use of couplings on either grooved or plain ended
pipe. This means of piping construction in oil fields and power plants is world-wide and is
considered to be the most versatile, economical and reliable piping system.
The grooving system of construction is up to three times faster to install than hand
welding, easier and more reliable than threading or flanging and the movement
flexibility allowed by the coupling makes installation easier and faster.
Also available to make the mechanical piping system complete are the
following grooved fittings:
elbows, tees, laterals, reducer, valves and adaptors for converting
from flanged and threaded lines.

PORTABLE MACHINES TAKE THE CORRECTION
MACHINE TO THE PROBLEM… NO LONGER DOES
THE WORK–FORCE HAVE TO TAKE THE PROBLEM TO
A DISTANT CORRECTION MACHINE.
Portable machines for on-site construction and maintenance work are
designed for machining full faced, raised faced and grooved flanges as well
as bevelling and counter boring flanges.
These machines possess the features that make work easy:
– each unit is compact and light weight
– easy to use
– cut all types of grooves and root faces of weld
preparations
– reduce down-time
– save freight cost (to off-site repair machine shops)
– eliminate temporary leak sealing procedures
– reduce replacement flange inventories
These machines come in many sizes as one single machine cannot
machine all sizes of flanges. The required pneumatic power to operate
these machines varies as shown below.
