Fabricate Everything

JH Kelly has invested in the facilities and technology to pre-fabricate civil, structural, piping and electrical systems.

In-house detailing enables our shop foreman to “virtually” layout material for pre-assembly and fabricate large runs of pipe, conduit or steel in record time and in coordination with other trades.

Facilities Totals:

  • 140,000 sq. ft. Pipe Fab
  • 60,000 sq. ft. Module Fab
  • 15,000 sq. ft. Electrical Fab
  • 10,000 sq. ft. Civil / Carpentry Fab
  • 16 acres Laydown / Assembly

Longview Pipe Fabrication JH Kelly

Pipe Detailing and Fabrication

With over 140,000 square feet of piping fabrication space and 14 acres of outdoor racking and laydown area, JH Kelly is one of the largest pipe fabricators in the Western United States.

We combine great facilities with an accomplished in-house staff of piping designers and detailers experienced with 3D CAD.

  • 3/8″ – 120″ OD
  • Carbon Steel, Stainless Steel, All Alloys, Copper Brazing
  • Multiple locations
  • Lean Manufacturing Process

Electrical Design and

JH Kelly combines BIM technology with Trimble layout systems to create efficient electrical fabrication assemblies, delivering detailed pre-fabricated electrical components to our customers.

We leverage Revit and other BIM technologies to deliver electrical work packages for our fab shop teams that lower costs and increase safety in the field.

Our process offers a seamless transition from model, to fabrication, to electrical field installation.

  • Conduit runs/racks, Cable Tray
  • Underground Duct Banks
  • UPS Systems, Rotational UPS Systems


Civil and Carpentry

JH Kelly assembles civil and structural components in our Longview fabrication facility, transporting complete or partial assemblies to the site to be erected. We combine good design with modern high-performance components and quality controlled manufacturing procedures.

This work is carried out in two stages: Fabrication of components in a place other than final location, and their erection in final position.

  • Columns
  • Foundations / piers
  • Wall panels / roof panels
  • Beams
  • Inertia bases / equipment pads

Module Fabrication

Modular fabrication is not just a time-saving tool, it is a conscious approach to engineering, estimating and field execution.

JH Kelly has researched and invested in modular fabrication techniques that deliver multi-trade systems in record time and with a high degree of quality.

  • utility modules
  • modular mechanical rooms
  • module electrical rooms
  • HVAC / scrubber modules
  • pipe / conduit racks
