Industrial processing equipment and nuclear components are designed for very different applications, but they answer to the same physical realities: pressure, temperature, corrosion, fatigue, and stress. The drawings might look different and the end customers definitely are, but the quality discipline behind a well-built chemical processing vessel and a well-built CANDU pressure-retaining component is, in practice, the same discipline.

As a world-class Tier‑2 supplier of specialized fabricated nuclear components, tanks, vessels, custom tooling, and mock-ups required for reactor refurbishment activities, Arrow Engineered Products (AEP) is a premier choice that supports Tier‑1 contractors.

In this month’s blog, we present an AEP case study in which we delivered a custom-engineered solution for a CANDU reactor refurbishment project.

In highly regulated sectors like nuclear energy and industrial processing – including industries such as chemical and oil and gas – there’s an important distinction

Sectors such as chemical, pharmaceutical, oil and gas, and food processing rely on engineered vessels to safely contain and process a wide range of materials. Unlike standard containers, these vessels are designed to withstand high pressures and temperatures and are fabricated from specialized materials that resist corrosion and contamination.

Because they operate under demanding conditions where safety, efficiency, and product integrity are critical, these vessels must be precisely engineered and fabricated to meet strict specifications and ensure reliable long-term performance.

Arrow Engineered Products (AEP) is well known for supplying large, purpose-built equipment of uncompromising quality for demanding industrial sectors, including nuclear. While these custom-built, heavy-duty products are central to what we do, they represent only part of the capabilities and expertise that define AEP.

The messaging from Ontario’s government and the energy sector is clear: nuclear technology is powering the province’s future.

To many industry insiders, this comes as no surprise. Ontario is already leading in small modular reactor (SMR) technology, building the first grid-scale SMRs in a G7 country. This technology can supply clean electricity to hundreds of thousands of homes while supporting economic growth and local job creation.

At Arrow Engineered Products (AEP), progress is driven by coordinated teamwork and a focus on operational excellence. Across our facilities, from Stratford to Cambridge South, teams are managing tight timelines, expanding nuclear fabrication capabilities, completing complex CNC bending and welding projects, and implementing ongoing process improvements.

The Organization of Canadian Nuclear Industries (OCNI) presented their Nuclear Industry Day on September 10th and 11th at the Scarborough Convention Centre in Toronto, Canada. 

The two-day event brought nuclear procurement professionals, supply chain leaders, and industry executives from across Canada together to explore supply chain opportunities, strengthen nuclear culture, and discuss the priorities shaping the industry’s future. It also opened doors for suppliers to access new markets, build partnerships, and gain valuable insights from industry experts.

When it comes to industrial processing equipment such as mixers, pressure vessels, and heat exchangers, only specialized fabrication facilities can consistently deliver the integrity, reliability, and performance you need to keep your business running with peak efficiency and profitability. 

Many fabrication shops simply don’t have the infrastructure, certifications, or depth of expertise required for these critical applications.

The engineers at Arrow Engineered Products recognize the importance roles that process safety, efficiency, and regulatory compliance play in the design, fabrication, and assembly of industrial heat exchangers, particularly in the energy and nuclear sectors. Every design choice, material selection, and fabrication detail directly impacts operational reliability and lifecycle performance, demanding a rigorous approach to achieving a high-quality product.
