Safety Break-away Couplings

Safety Break-away couplings are used to prevent pull away accidents, protect terminal and loading/unloading equipment and eliminated unwanted product release. The break-away couplings has a diverted breaking point which will break at a determined break-load where upon the internal valves will automatically close on both sides. This will in a longer time frame minimize down time, save money, equipment and the environment.

The Safety Break-away couplings are available as Industrial and Marine type.

Industrial Break-away

Typically installed into loading arm and hose assemblies, where at least one side of the coupling is attached to a rig and fixed point.

Marine Break-away

Marine Safety Break-aways are designed to only release by inline pull and used between two strings of hose.

Safety break-away Coupling function

The SBCouplings, Safety break-away couplings has 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.

How it works - before and after emergency disconnect

Non-axial forces concentrate the tension forces more strongly on one bolt, so that the safety break-away coupling reacts in a natural way to the reduction of the hose break forces.

Before emergency disconnect

The safety break-away valve consists of two halves, each with a valve that has a o-ring seal.

After emergency disconnect

When the SBCouplings separate, it allows the valves to close. The two valves closes rapidly, minimizing exposure to personnel and the environment.

Features and Applications

Features

• Passive security against situations where a hose or loading arm could be subjected to inadvertent excessive loads.
• Design features are a simple mechanism and no loose components which could belost after release.
• Operates independently of shut off safety system and does not require an externalpower source.
• Easy to reset on site with one person High flowrate / low pressure drop
• Very low loss, positive shut-off of both coupling halves results in minimum product loss.
• Lightweight and robust design.
• Available with ANSI/DIN flanges or threaded (BSP or NPT).
