Spray & Brush Epoxy Technology
Case Study: Luxury Mega-Yacht Fire-Suppression LinesOperating in a marine environment exposes plumbing systems aboard mega‑yachts to saltwater corrosion, movement‑induced stress and constant moisture. Over time, this leads to pinhole leaks, reduced flow and in some cases complete pipe failure. Replacing these pipes often requires tearing out cabinetry and finishes, cutting into bulkheads and custom‑fabricating sections to fit tight spaces – a costly and disruptive process for yacht owners and crew.
At Nu Flow BC, we specialize in trenchless pipe lining solutions that restore the integrity of onboard pipe systems without invasive demolition. Our spray‑in‑place and brush‑applied epoxy technologies create a durable “pipe within a pipe” that isolates the original pipe from seawater and corrosion, restoring flow and extending service life.
Case Study: Luxury Mega‑Yacht Fire‑Suppression Lines
en corrosion created pinhole leaks in the 80 mm and 100 mm steel fire‑suppression pipes on a luxury mega‑yacht, traditional replacement would have meant cutting through interior finishes and fabricating custom pipe sections. Instead, our team developed a non‑invasive plan that combined epoxy liners for straight sections and spray‑in‑place epoxy for the tight bends and hard‑to‑reach areas. The result was a seamless epoxy barrier that restored the system’s pipes eliminating the need for interior demolition and avoided expensive custom fabrication.
Spray & Brush Epoxy Technology Epoxy Technology
Our epoxy lining process starts with a thorough inspection and mechanical cleaning of the pipes to remove corrosion, scale and marine deposits. For straight runs, we install a resin‑saturated felt liner that is pulled through the pipe and cured to form a new structural pipe. In sections with multiple bends or limited access, we use spray‑in‑place epoxy applied with specialised equipment to coat the interior of the pipe evenly. Both methods bond to the host pipe, creating a seamless, corrosion‑resistant barrier designed to last decades. Because the epoxy is applied internally, there is minimal disruption to the vessel’s interior and no need for excavation.
Pre‑Cleaning & Preparation
Preparing the pipe is critical for a successful lining. Nu Flow BC employs high‑speed cleaning equipment, such as Picote’s Maxi‑Miller and Cyclone chains, to descale and clean corroded pipes on vessels. This technology can remove scaling, rust and marine deposits from hawse pipes and similar applications, ensuring the epoxy adheres properly and the finished liner has a smooth interior.
Applications for Mega‑Yachts
Our spray and brush epoxy solutions are ideal for a variety of onboard systems, including:
– Fire‑suppression and sprinkler lines
– Potable water and seawater supply lines
– Grey and black water drainage
– HVAC condensate and cooling lines
– Pool and spa circulation pipes
