I3
Pipeline Design Team
I3 Engineering and Consulting is your pipeline design specialist in the Mid-Atlantic. Our recent projects have ranged in size from 6 inch through 42 inch; from just a few hundred feet to projects covering hundreds of miles; from New York to South Carolina. We are your one-stop shop for any facet of a pipeline project.
I3's engineers are well versed in both the DOT Part 192 and ASME B31.8 codes. We perform pipeline classification and pipe material specification per those codes and develop hydrostatic testing plans for the testing of pipelines prior to in-service.
We have performed countless designs of bored crossings for both conventional pipeline bores and horizontal directional drills including the pipe stress analysis for both.
Our engineers layout and design the facilities required along the pipeline including valve settings, pig launchers and receivers and pipeline drips. We utilize the latest software with 3D CAD modeling to perform all our piping layouts and designs. The software auto-generates bills of materials and isometric drawings as needed for the client.
