SUCCESS

Flux-Cored (FCAW-G) Welding

The Cheyenne Plains Gas Pipeline

project was the first major pipeline in

the U.S. to use high strength X-80

grade pipe. The contractor, U.S.

Pipeline, was looking for ways to

increase productivity while still creating

high quality welds that could pass

radiographic inspection.

Lincoln Electric Pipeliner

G80M

gas-shielded flux-cored wire for

use on the pipe tie-ins at connection

points and railroad crossings near

populated areas.

Using a wire process yielded results

that were three to five times faster

than the stick welding typically used

for pipeline welding. The Pipeliner

G80M provided high quality and

flawless operation with its smooth

arc and low spatter levels.

turned to new Lincoln Electric

Pipeliner

G80M gas-shielded

flux-cored wire to weld the

pipe tie-ins for the 380-mile

Cheyenne Plains Gas Pipeline

project, which used X-80

grade pipe.

-CHALLENGE-

uring the summer and fall of

2004, the plains of the west

were busy with the hustle and

bustle of cranes, trucks, heavy equip-

ment and supplies to lay pipe for the

Cheyenne Plains Gas Pipeline Project.

The 380-mile, 36-inch natural gas

pipeline runs from the Cheyenne hub

in Colorado to existing pipelines near

Greensburg, Kan. Once operational in

early 2005, the pipeline will export

560 million cubic feet of natural gas

per day from Wyoming to growing

markets in the mid-continental U.S.

and further east.

The $425 million pipeline, owned by

El Paso Corporation, was being con-

structed in three spreads which were

connected in the final phase of the

project. Spread one was contracted to

Associated Pipelines while spreads

two and three were handled by U.S.

Pipeline, Inc.

The Cheyenne Plains Gas Pipeline

Project was the first major pipeline in

the U.S.

to use X-80 grade pipe. Already a

standard in other parts of the world,

the X-80 pipe provides higher strength

with a thinner wall.

As on any pipeline project, welding

plays a critical role in the construction

process. But what made this project

unique was the extensive use of wire

welding to provide high productivity. A

new consumable from the Lincoln

Electric Company, the Pipeliner

G80M

gas-shielded flux-cored wire, was

selected by the evaluation team at

U.S. Pipeline, Inc. for use on the pipe

tie-ins at connection points and road

crossings near populated areas. These

welds, completed manually by inde-

pendent pipeline contractors, connect

the mainline pipe to the thicker walled

pipe of the tie-ins.

For the mainline pipe, a CRC-Evans

automated welding system was used

in combination with Lincoln’s premium

SuperArc

L-56 copper coated gas

metal arc wire.
