Underground Piping System

At SCG, we design, install, maintain, test, and repair underground piping systems that form the backbone of natural gas transmission and distribution networks in our service area—from the Upper Peninsula of Michigan to Southern Texas and Middle America in between.

Our integrated approach combines engineering excellence with field-proven construction techniques to deliver piping infrastructure that meets the highest standards of safety, efficiency, and longevity.

Comprehensive Solutions for Piping Infrastructure

End-to-End Piping Expertise

From initial feasibility studies through final operations, our team provides services for all aspects of development:

Material selection and procurement: We secure the highest quality pipe materials, protective internal and external coatings, and components that are optimized for your specific operating conditions.
Trenching and bedding: To ensure structural stability and corrosion prevention, we utilize precision hydro-excavation, and proper bedding installation.
Pipeline installation: Our industry-leading welding and connection installation methods promote meticulous placement, alignment, and joining of pipe segments.
Corrosion protection systems: Extend pipeline system life and prevent premature failure with our comprehensive cathodic protection design and installation.
Backfilling and compaction: We protect your pipe integrity with engineered backfill methods that meet surface restoration requirements.
Testing and commissioning: We verify system integrity before operation with rigorous hydrostatic testing and commissioning protocols.

Advanced Installation Methodologies

Our installation capabilities extend beyond conventional open-cut installation:

Horizontal Directional Drilling (HDD): This minimally invasive pipeline installation extends beneath waterways, environmentally sensitive areas, and existing infrastructure.
Boring and tunneling: To avoid surface disruption, we use advanced boring and tunneling techniques to cross roadways, railways, and other obstacles.
Microtunneling: In urban environments and places where minimal surface disturbance is a must, we use this precision pipeline installation technique.

Applications and Industries Served

The diverse selection of applications we can utilize are based on the scope and needs of the project as well as these industries that we serve:

Interstate transmission pipelines
Urban distribution networks
Gathering systems from production facilities
Industrial plant piping
