Upstream Engineering is a custom tube/pipe fabricator with our major emphasis on precision bending. We specialize in Mandrel bending, or more precisely called Rotary Draw Bending.

Our bending capacity is from 0.250” to 4.000” diameter tubing and 1.000” to 3.00” pipe. All of our bending machines are fully CNC (Computer Numerically Controlled) to assure the highest precision and quality.

We can also provide numerous secondary operations such as trimming, deburring, bead rolling, flaring, swaging, slotting, welding & polishing. (See Other Capabilities)
