Industrial General Contractor since 1955

Process piping that
STANDs UP to the pressure.

Process and utility piping — fabricated, installed, welded and tested by Lilja crews, from plant services to high-temperature process lines.

Fit or welded to code, tested before you run it.

Piping is usually where a shutdown either finishes on time or doesn’t. Our pipefitters and welders work to the code the job calls for, and joints are tested before the line goes back into service — not after something lets go.

During a construction build the piping, the brick and the steel all sit on the critical path at once. Having them under one contractor is the difference between a sequenced schedule and three companies waiting on each other.

What our pipe crews run.

  • Process piping
  • Plant utility and service lines
  • High-temperature and cooling systems
  • Shop and field welding
  • Pipe supports and racks
  • Testing, flushing and tie-ins
  • Skid Fabrication - Oxygen, Gas, Water, and Air

Every crew works to the same safety standard that earned Lilja a 0.66 EMR — well below the 1.00 industry average. See how we hold it.

BRING US YOUR TOUGHEST JOB.

From concept to completion, whatever the size tell us what you need built and we'll deliver.
