Revolutionizing Pipefitting: Lindsey Elliott’s Robotic Solution to a Tough Trade Challenge
Lindsey Elliott has a unique passion: bolts. At the 13th annual Bolting Symposium last year, she fondly recalled the highlight of playing “Bolting Bingo” alongside numerous self-described “torque dorks,” enthusiasts deeply invested in the technical nuances of bolted joints. But for Elliott, a former engineer and planner at ExxonMobil, this enthusiasm goes beyond hobbyist interest — it’s the foundation of a transformative approach to improving industrial infrastructure.
For years, Elliott has focused on enhancing the infrastructure that transports oil, gas, and petrochemicals. Her attention zeroed in on a seemingly humble yet critical component: the bolts that connect pipe sections, technically known as “bolted flange joints.” These bolts demand strenuous physical labor to loosen and tighten, a repetitive task that frequently leads to injuries among pipefitters. Compounding the problem is a well-documented labor shortage in the trades, making productivity and worker safety urgent priorities.
Addressing Labor Challenges with Automation
“Those people get really tired when they’re asked to work 12 hours a day for three months in a row,” Elliott told TechCrunch, emphasizing the grueling demands placed on pipefitters across North America. She highlighted that “pipefitting productivity is notoriously low,” a reality echoed by professionals throughout the U.S. and Canada.
In response, Elliott co-founded Nexterity, a startup that introduces a remote-controlled robot designed to take on the physically taxing task of bolt handling. Selected as part of the Startup Battlefield 200 for TechCrunch Disrupt, Nexterity’s innovation promises to fundamentally change this blue-collar job by increasing safety and efficiency.
The robot, which comes in two main parts that encircle a pipe, is battery-powered and capable of sliding along the pipe to loosen or tighten up to four bolts simultaneously. This approach not only reduces the physical toll on workers but also significantly speeds up a traditionally slow and labor-intensive process.
Design Driven by Industry Insight
Elliott’s design was shaped by extensive conversations with industry experts, including attendees of the Bolting Symposium and members of the Pressure Vessels & Piping Division of the American Society of Mechanical Engineers (ASME). These discussions revealed a key insight: about 80% of pipes in use fall within a diameter range of two to eight inches (NPS2 to NPS8), creating a strong case for repeatable, standardized automation.
“When you have that much repeatability, you have a fantastic candidate for automation,” Elliott explained. This focus on common pipe sizes allows Nexterity to tailor its robot configurations efficiently, ensuring compatibility across a wide range of industrial applications.
Moreover, the compact design is portable enough to fit inside a Pelican case, enabling a single worker to transport and deploy the robot easily. This portability supports Nexterity’s innovative business model, which treats their robots like rental construction equipment — providing flexibility and convenience to contractors who can’t afford to invest heavily in specialized machinery.
Market Potential Beyond Oil and Gas
While Nexterity’s roots lie in oil and gas infrastructure, Elliott sees the potential for this technology to extend far beyond. “I think it would shock a lot of people just how big this market is,” she noted. Piping infrastructure is ubiquitous, powering sectors such as water and wastewater treatment, food and beverage processing, mining, nuclear energy, and emerging green and sustainable manufacturing facilities.
All these industries rely on similar bolted flange joints, making automation solutions like Nexterity’s robot a promising innovation with broad applicability. By reducing physical strain, enhancing safety, and boosting productivity, this technology addresses critical industry challenges while supporting sustainability goals.
