In-House Fusion, Start to Finish

High-density polyethylene (HDPE) pipe is the workhorse of modern gas gathering and water transfer. It doesn't corrode, it flexes with frost and settling, and properly fused joints are as strong as the pipe itself. The quality of an HDPE line comes down to the quality of its fusion joints. That's why Eaton Construction keeps fusion in house.

We fuse all of our own mainline poly pipe with a McElroy MFT 20 Fast Fusion machine, and we're capable of fusing all sizes of poly pipe. All of our employees are trained and certified in poly-pipe fusion. New employees are not allowed to fuse unsupervised for sixty days, even after certification. Our owner, Wayne Eaton, is on the job site every day to make sure the work meets specifications.

How We Make a Joint

Butt fusion follows a strict sequence: face the pipe ends square, align them, heat them to the specified temperature, then bring them together under controlled pressure and hold until the joint cools. We follow the pipe manufacturer's and the operator's fusion procedures, inspect every bead, and pressure-test the finished line before backfill.

Built for Dakota Conditions

Western North Dakota winters and South Dakota's clay and rock both test a line. We bury below frost to your spec, bed the pipe properly, cut rock with our own rock saw when we hit it, and plan crossings and tie-ins so the line holds up long after we leave.
