In the defense sector, reliability is non-negotiable. Whether it’s a ship navigating turbulent seas or an aircraft relying on flawless hydraulic systems, every component must perform with absolute precision. At Pines Engineering, we understand that the smallest bend can have the biggest impact. Our tube and pipe bending solutions are engineered to meet the extreme standards demanded by the U.S. military and its suppliers—helping safeguard performance, safety, and readiness across the defense supply chain.
The U.S. Navy’s fleet is a marvel of modern engineering—dense with piping systems, cooling lines, and hydraulic networks that must perform under tremendous stress. Within every vessel lies thousands of precisely bent tubes and pipes that keep critical systems running, from propulsion and fuel delivery to fire suppression and ballast control.
Pines Engineering’s line of CNC and NC tube benders gives shipyards and defense contractors the ability to shape these complex geometries with unmatched repeatability and accuracy. Our machines are trusted by defense facilities, including a U.S. Navy shipyard that recently selected the Pines #8 NC bender to handle 2- to 6-inch NPS pipe. The system met strict Navy specifications for ovality, wall thinning, and bend precision—requirements that define mission readiness.
When tolerances are tight and materials are demanding, the difference between acceptable and exceptional lies in control. That’s where Pines leads.
Every Pines bender—whether manual, electric CNC, or hybrid CNC—is built to produce consistent, distortion-free bends across a wide range of alloys, including stainless steel, carbon steel, Inconel, and titanium. These materials are standard in defense manufacturing due to their strength-to-weight ratios and corrosion resistance—but they’re also notoriously difficult to form.
Pines benders are equipped with advanced controls and custom tooling solutions that minimize ovality and wall thinning even under heavy wall loads. Mandrel and wiper-die support systems ensure smooth internal finishes and reduce the need for post-processing, saving both time and cost. For defense applications, where every part must meet precise fit-up requirements, these advantages are essential.
Today’s Navy is evolving rapidly—integrating advanced automation, energy efficiency, and modular ship design. As systems become more compact and specialized, tube routing grows increasingly complex. Pines benders offer the flexibility to bend in multiple planes and radii, creating intricate piping systems that fit precisely within tight compartments.
Examples of naval applications include:
By delivering accurate bends the first time, Pines helps shipyards reduce rework, cut waste, and improve turnaround time—keeping naval operations on schedule and on budget.
While the Navy is one of Pines’ most visible defense partners, our machines also serve a critical role in aerospace, ground vehicle, and munitions production. The same precision that shapes ship piping also supports hydraulic and pneumatic tubing for aircraft landing gear, brake systems, and flight control assemblies. In armored vehicles, tightly routed fuel and hydraulic lines demand identical accuracy and resilience.
Because our benders can handle a wide range of diameters and materials, they provide a single, reliable platform for defense contractors building or maintaining mixed fleets—whether maritime, airborne, or ground-based.

Defense technology never stands still, and neither does Pines. As military systems evolve toward automation, electrification, and smart manufacturing, we continue to push the boundaries of precision bending.
Our Hybrid CNC Benders combine programmable control with manual flexibility—ideal for prototyping or low-volume production runs. All-Electric CNC models deliver high-speed, high-repeatability performance with advanced motion control for complex multi-axis bends. Meanwhile, our Metric Benders allow global defense contractors to standardize across international specifications.
We also provide rebuild and retrofit services that bring legacy equipment up to modern standards. Whether upgrading controls, adding automation features, or replacing worn components, our engineers ensure that even decades-old machines perform like new—extending ROI and supporting sustainability initiatives across the defense manufacturing lifecycle.
At its core, the defense industry relies on collaboration. Every shipyard, subcontractor, and OEM contributes to the collective strength of the nation’s military infrastructure. Pines Engineering is proud to be part of that network—providing the tools and technical expertise that help keep our forces ready.
Our legacy of innovation stretches back decades, but our commitment remains the same: to engineer equipment that performs under pressure, in every mission, every time.
As defense technology evolves and demands intensify, precision bending will remain a foundation of reliable performance. From naval shipyards to aerospace hangars, Pines Engineering continues to empower America’s defense manufacturers with the equipment, expertise, and support they need to bend with confidence.
