Mann Tek Safety Break-away Coupling Marine Female NPT

Application

• Coupling is designed to minimize spillage and damage associated with pull away incidents.
• Typically used in ship-to-offshore platform and ship-to-ship product transfer operations

Features

• designed to be installed within a hose string where the coupling will have a length of hose attached to both sides
• coupling automatically senses an excessive load, closes the valves and disconnects
• release is executed when force causes bolts to break

Construction

• 316 Stainless Steel body
• FKM O-rings

Available Options

• Also available in 150# Flange BSP thread, DN Flange, 300# ASA Flange, Grooved Ends or any combination thereof. Consult Dixon for more information.
• Optional Non-closure Design available, consult Dixon for more information. The non-closure design is an economical alternative which allows the coupling to break away due to pull-away/drive-away incidents thus protecting piping systems and equipment. The design allows spillage of product in these instances due to the lack of valving in the coupling. Useful applications where non-hazardous product is being conveyed and where there are no environmental concerns.

How it works

• The safety break-away valve consists of two halves, each with a valve that has an O-ring seal. When the safety break-away couplings separate, it allows the valves to close. The two valves close rapidly, minimizing exposure to personnel and the environment.
• Safety break-away couplings have three external break bolts. In the case of axial tension all of the bolts take up the force corresponding to the break force on the hose with a safety margin.
