Marcellus

Building and improving midstream shale gas infrastructure

Linde has laid hundreds of miles of gathering pipelines, connecting wellheads to transmission lines, and built water draws to well pads and compression stations.

Improving Marcellus Infrastructure

Since the first gas wells were dug in Washington County PA in the early 2000’s, Marcellus gas has transformed Pennsylvania and Linde Corporation. Today, Linde is still heavily involved in the gas industry, in both a supportive role in fabrication as well as a continuing role in constructing and upgrading gas pipelines to accommodate the additional gas wells that have been built over the last two decades.

Pipeline Construction

The heart and sole of Linde Corporation is in pipeline construction, whether that be large 24 inch lines in the Northern Tier of Pennsylvania, trenchless horizontal directional drills under sensitive streams and wetlands, or in distribution throughout commercial and residential areas downstream.

Safety

Safety

Linde employees have a simple credo when it comes to work on the job. “Zero-zero.” That is, we aim for zero incidents and zero accidents on every job site, every day. We accomplish this through commitment, training and staying on top of changes within the industry.

Erosion & Sediment Control

Erosion & Sediment Control

Once we have protected our people, then we protect the environment. Linde Corporation places enormous importance on this “first step” in the pipeline spread process. Before ground can be broken, preventative measure need to be taken to control erosion and eliminate sediment from being carried by runoff into neighboring streams and waterways. The standard methodology is to use silt fence, or composite filter socks. A filter sock is a fabric tube, typically filled with wood chips or compost. Silt socks and silt fences allow water to flow through at a controlled rate while trapping sediment and protecting our waterways.

Clearing and Grubbing

Clearing & Grubbing

Before a pipe trench can be dug the land must be cleared and grubbed. Linde has the a full fleet of excavators, bulldozers, and specialty equipment to expedite this job and keep ahead of the pipeline crew.

Welding

Welding

Before being laid in the trench¸ lengths of steel pipe are precisely laid out using GPS. A team of expert welders join the pipe together, and every weld inspected and marked so that it can be found without excavation in the future.

Trenching

Trenching

To maximize the efficiency of the pipeline spread, Linde utilizes their Tesmec trencher, of which there is only one other in North American and sixteen globally. 1300 feet can be trenched in a single day in good soil and 600 feet a day of solid stone, with the biproduct being high quality fill.

Compared to 600 feet possible with an excavator, and the necessity for drilling and blasting when bedrock is found, it is no secret why the Tesmec Trencher is the pride and joy of the Linde fleet and used whenever the terrain allows.

Seeing a football field length of solid steel pipe, curving around bends, being simultaneously lowered into a trench by a team of excavators is truly a sight to be seen. However, this is just another day at the office for Linde's pipeline team who works in synchronization like a well oiled machine.

Restoration

Once the pipe is in the ground, we cover it with clean fill, grade, reseed and even landscape the disturbed area to get it as close to possible to what it was before we broke ground. In some cases, the pipeline is actually converted into a public hiking trail.

Marcellus Construction

To minimize facility downtime, Linde Corporation is routinely called on for on-site fabrication for compressor stations, pigging launchers and receivers, meter sets and skids, valve risers, fabrication for hot taps, and other pipeline components.

In addition to fabrication, our team has vast experience in the construction of compressor stations, as well as well pad work including their construction and installation of compressors at the well pad.
