Pipe Repair products offer a fast, safe way to seal splits, holes, and corroded sections instantly – often under full system pressure – avoiding the need for expensive and time-consuming network shutdowns.
Engineered Marine Fittings for Safe, Secure Pipelines
Piping systems onboard ships are critical to the safe and efficient operation of vessels, carrying seawater, fuel, cooling water and essential services throughout the ship. In these environments, pipe fittings and connections—particularly couplings and flange adaptors – play a vital role in maintaining system integrity. They must deliver secure, leak-tight performance while withstanding constant vibration, thermal movement and exposure to corrosive saltwater conditions.
Viking Johnson design and manufacture a dedicated range of marine couplings and flange adaptors specifically engineered for these demanding applications. The proven range is approved for use in marine environments, with certification from major authorities including ABS and Bureau Veritas
The marine environment
Managing Movement in Marine Pipework
Unlike static land-based systems, marine pipework is subject to continuous motion.
Pipe runs are often fixed to the vessel structure, meaning connections must absorb movement, accommodate misalignment and relieve stress to prevent fatigue or failure.
Reliable fittings are therefore essential to ensure operational continuity, minimise maintenance and maintain safety at sea.

Mechanical Fittings are Critical
These fittings are designed to accommodate angular deflection and controlled movement within the pipe system, reducing the need for additional expansion components and protecting against stress-related failures. Enhanced features such as corrosion-resistant finishes, resilient nitrile gaskets and integrated locating plugs help prevent coupling creep caused by vibration and repeated movement onboard.
In shipbuilding and vessel maintenance, high-performance pipe fittings are not just components—they are fundamental to ensuring reliability, safety and long-term performance across all onboard systems.
