The document discusses Weatherford's extensive experience in manufacturing and deploying pipeline pigs for over 40 years. It offers a range of standard and specialized pigs for various pipeline cleaning, inspection, and maintenance needs. Standard pigs include bidirectional pigs, cup pigs, and poly/foam pigs. Specialized pigs are designed for challenging conditions and include dual-diameter, contour, gauging, D-scaling, and D-waxing pigs. All pigs are manufactured according to rigorous quality standards and testing procedures.

2. Standard and Specialized Pigs
Maintaining a legacy of pipeline pig success
Weatherford’s Pipeline & Specialty Services group, through its Kopp heritage, has
nearly 40 years experience in manufacturing and deploying pipeline pigs—setting
standards in pipeline cleaning, inspection and maintenance. We offer an extensive
range of high-quality, reliable pigs, either off-the-shelf or custom-designed to meet
your specific requirements.
Our pigs are available around the world and applicable to onshore and offshore,
shallow and deepwater, industrial and municipal, single-phase and multiphase,
and multidiameter pipeline applications.
Our pigs are constructed of highly wear-resistant polyurethane material and
incorporate innovative design features to maximize flexibility and reliability
over a wide range of cleaning tasks.
All pigs are manufactured in our facility, which
is certified to ISO 9001:2000, OHSAS 18001
and OHSAS 14001. The performance of each
pig is analyzed in our test facilities to ensure your
satisfaction. Our pigs are also available to meet the
ATEX requirement for surface resistance of < 1 GΩ.

3. Pipeline Pigs
Why pig your pipeline?
Pigging is essential to maintaining and improving line flow rates, avoiding expensive blockage repair,
inhibiting corrosion and facilitating more accurate in-line inspection runs.
Whether your need is for conventional or specialized pigs, Weatherford has the necessary components to
meet the needs of the industry. In this image, a customized gel-cleaning pig train is illustrated to show the
structural design of the train in which the bidirectional and brush scraper pigs remove debris from the pipe
wall as they pass through the line. Highly viscous pickup gel collects and transports the loose debris to the
receiver. A separator gel protects the pickup gel and reduces any forward bypass of liquids.

4. Standard Pigs
Offering a range of options for almost any condition
Weatherford manufactures a standard range of pigs, including bidirectional (bi-di) pigs,
cup pigs and poly/foam pigs. Each pig has several options available to meet your
specific needs.
Bi-di pigs are the mainstay of our Kopp
pig line. These tough, versatile pigs offer
remarkable efficiency and reliability under
demanding field conditions. These pigs
are based on a proven modular design with
interchangeable components that enable
bi-di pigs to be quickly adapted to any task.
After completing a pressure-testing run, a
bi-di pig can be left in the receiving trap,
ready to be used during dewatering
operations in reverse direction.
Discs ranging from 2 to 60 in. can be fitted
to the same type of body so that you can
use the bi-di pig in a wide range of pipelines.
You can use bi-di pigs during many
maintenance, precommissioning and
rehabilitation operations, including cleaning,
filling, batching, dewatering and drying.

5. Pipeline Pigs
Cup pigs are built on the same body as the bi-di pigs and are equipped with cups of
abrasion-resistant polyurethane. These cups are considerably more flexible than normal
discs and have a lower contact pressure, making them ideal for long-distance pigging
runs in which wear is a consideration, such as during the commissioning of dry pipelines
and the separation of different media.
Poly/foam pigs have a flexible, bullet-shaped body with
a sealed, concave base. This coated base prevents the
propulsion media from passing through the open cell
foam. These pigs have several options, including
a bi-di version, wear-resistant coating and brush stripes.
You can use poly/foam pigs for cleaning and drying
pipelines. The simple design means no need for
special pig traps.
In addition to our featured pigs,
we offer a range of other pigs.
Other standard pigs:
• Polykast pigs
• Sphere pigs
• Flex-I-pigs
Other specialized pigs:
• Tandem/dual-module pigs
• Triple-module pigs
• Bypass pigs
• Pressure bypass pigs
• Adjustable bypass pigs

6. Specialized Pigs
Tackling tough environments with specialized pigs
Pipeline conditions vary dramatically from site to site, and even
within the same well. To meet those challenges, Weatherford
also offers specialized Kopp pigs.
We manufacture a range of specialized pigs capable of meeting
the most demanding of applications. Like our standard pigs,
these specialized pigs undergo the same manufacturing
processes and rigorous testing.
Our range of specialized pigs includes:
• Dual-diameter and multidiameter
• Contour
• Gauging
• D-Scaling
• D-Waxing
Dual-diameter and multidiameter pigs are
available for a wide-range of pipe sizes and
can be custom-built for even more choices.
These pigs provide innovative pigging solutions
to challenging pipeline diameter configurations.
Contour pigs and gauging pigs can help to
determine certain pipe characteristics. Contour pigs
can determine the minimum bend radius in pipes,
while gauging pigs are used to proof a pipeline’s
minimum bore.

7. Pipeline Pigs
D-Scaling pigs are designed to
remove hard deposits, such as
calcium carbonate, from the pipe
wall. The pigs consist of a tractor
module at the front equipped with
highly wear-resistant polyurethane
cups and two cleaning modules
equipped with studs.
Couplings join all three modules, and the tractor module drives the coupled pig.
The cleaning modules consist of heavy-duty polyurethane cups with an OD significantly
smaller than the ID of the pipeline. Each cup is fitted with steel studs capped with
balls designed to prevent damage to the pipeline walls. The balls are made of highly
wear-resistant tungsten carbide steel; and the diameter across any two opposite studs
is greater than the ID of the pipeline. This design ensures that the balls are pressed
against the pipeline wall under a load and work to better break up the deposits.
D-Waxing pigs are designed to remove wax and paraffin deposits from the pipe wall.
Like the D-Scaling pigs, the D-Waxing pigs consist of a tractor module and two
cleaning modules.
The cleaning modules consist of heavy-duty polyurethane cups that have an OD
significantly smaller than the ID of the pipeline.
Each cup is fitted with an appropriate number of brushes to provide circumferential
coverage to cut into the accumulated wax deposits and shear them off. The OD of
any two opposing brushes is slightly larger than the ID of the pipeline so that the
brushes are pressed against the pipeline wall under a load, ensuring that the brushes
are better able to break up the wax deposits. This brush configuration helps to prevent
rotation of the pig.
