YN-Fire Protection Cover-coupling is a new coupling technology developed for shipbuilding. When a fire occurs, the expanding fire protection expands to protect the coupling. In this process, the coupling remains fully functional without any restrictions.
YOUNGNAM Couplings are the easiest way to join and repair pipes of all materials. They require no special tools or pipe-end preparation. Flexible, lightweight, construction; YOUNGNAM Couplings handle pipe-misalignment, vibration, and are used in shipbuilding, wastewater treatment, general industry, and construction.
