Nexterity wants to automate the hard, dangerous part of pipefitting

The manual tightening of industrial pipe flanges is a laborious and hazardous task. Each bolt requires significant torque, often applied in awkward or confined spaces. This process is not only time-consuming but also exposes workers to risks of musculoskeletal injuries, slips, falls, and exposure to hazardous materials.

The sheer physical demand of this work contributes to a high incidence of workplace injuries in sectors reliant on extensive pipe networks. Beyond the immediate safety concerns, the repetitive nature and difficulty of manual tightening can lead to inconsistent torque application. This inconsistency can compromise the integrity of pipe systems, potentially causing leaks and costly downtime.

The Growing Need for Automation

As industries scale and operate under increasing pressure to meet deadlines, the inefficiencies and risks of manual pipefitting become more pronounced. Stringent safety regulations and the drive for operational excellence necessitate more reliable and safer methods. The current reliance on manual labor for critical tasks like bolt tightening presents a bottleneck to progress and a persistent source of risk.

The economic impact of these inefficiencies is substantial. Delays in project completion, increased insurance premiums due to accidents, and the cost of leak repairs all add up. Furthermore, the specialized skills required for pipefitting are in demand, making the retention and training of skilled labor a continuous challenge. Automation offers a clear path to address these multifaceted issues.

Introducing Nexterity's Robotic Solution

Nexterity is addressing this critical need with a novel robotic solution designed to automate the challenging aspects of pipefitting. Their robot is engineered to efficiently tighten or loosen multiple bolts simultaneously. This capability directly targets the most physically demanding and time-consuming part of the pipefitting process.

A key design feature of Nexterity's robot is its portability. Packaged within a standard Pelican case, it ensures that the technology can be easily transported to various job sites. This mobility is crucial for industries where pipe systems are widespread and access can be challenging, such as oil and gas, chemical processing, and heavy manufacturing.

Practical Workflow and Impact

Consider a scenario in a chemical processing plant where a routine maintenance shutdown requires the disassembly and reassembly of several large-diameter pipe flanges. Manually, a team of experienced pipefitters might spend an entire shift, 8 hours, on just one complex flange connection. This involves individually torquing anywhere from 8 to 16 bolts, often in cramped conditions around the pipe.

With Nexterity's robot, the process is significantly streamlined. The robot is positioned around the flange, and its automated arms engage multiple bolts at once. It can precisely apply the required torque, ensuring each bolt is tightened to specification. This reduces the time spent on a single flange connection from 8 hours to potentially just 1-2 hours, a reduction of up to 75%.

The implications for compliance and safety are profound. Consistent, automated torque application minimizes the risk of leaks, which can lead to significant environmental and safety hazards. For instance, a leak of corrosive chemicals can cause severe damage to equipment and pose immediate danger to personnel. By ensuring a proper seal, Nexterity's solution helps maintain compliance with stringent safety standards like OSHA's Process Safety Management (PSM) regulations, which mandate rigorous control over hazardous chemical processes.

Quantifiable Benefits for Your Practice

The savings extend beyond mere time. For a typical large-scale industrial project, the cumulative hours saved by automating bolt tightening across hundreds or thousands of flange connections can translate into millions of rupees. If a project involves 500 flange connections, and each connection saves 6 hours of manual labor at an average labor cost of ₹1,000 per hour, the direct labor savings alone amount to ₹30,000,000.

Moreover, the reduction in workplace injuries can lead to lower insurance premiums and reduced costs associated with lost workdays. A single serious injury can cost a company upwards of ₹5,00,000 in medical expenses, lost productivity, and potential legal fees. By mitigating these risks, Nexterity's technology contributes to a more stable and predictable operational budget.

The Future of Pipefitting

Nexterity's innovation represents a significant leap forward in industrial automation. By focusing on the demanding and dangerous aspects of pipefitting, they are not only improving efficiency but also creating safer work environments. The portability and precision of their robotic solution make it a practical and valuable tool for a wide range of industries.

This technological advancement is poised to redefine industry standards. As more companies recognize the benefits of automating such critical tasks, the adoption of solutions like Nexterity's is likely to accelerate. It signals a future where hazardous manual labor is replaced by intelligent, precise, and safe robotic systems.
