Viking Johnson couplings Marine 272,2-276,5 mm 2 plug KB connection

Viking Johnson marine couplings are designed to withstand the toughest marine environments. Ships are exposed to waves and motion, so piping must be flexible enough to withstand these dynamics without sustaining damage. Viking Johnson non-restraint marine couplings are unmatched in flexibility, durability and ease of installation, making them a must-have in marine environments.

Product Features

The marine coupling is made of galvanized ductile iron and is corrosion resistant. In addition, the NBR gasket protects against noise and vibration. The coupling has a wide range from a minimum of 272,2 mm to a maximum of 276,5 mm and can withstand a working pressure up to 33,48 bar. Furthermore, this coupling has a connection for cathodic protection. The coupling can withstand angular deflection up to 6° (2x 3°), eliminating bends or minor misalignments.

Installation

The fixed, non-rotating bolt head of only one bolt size (M12) over the entire range and one bolt tightening torque (55-65 Nm) for all pipe materials makes the coupling quick and easy to install. The coupling is also equipped with 2 removable fixation plugs that make it easy to slide the coupling over pipe ends during installation. Once installed, these plugs ensure that the coupling is firmly fixed between the pipe ends, preventing it from moving beyond its limits due to vibrations.
