3 Industrial Version Marine Version Non-Closure Version Safety Break-away Couplings

4 Industrial Version Safety Break-away Couplings Industrial break-away couplings are utilized in industrial product transfer installations. The industrial couplings are specifically designed to be able to activate with a tensile force being applied at an angle up to 90 degrees to the hose or pipe. INSTALLATION BETWEEN A FIXED POINT (PIPE, PUMP OR MANIFOLD) AND HOSE. SBC200AL

5 Safety Break-away Couplings Industrial Version The breaking bolt industrial break-away coupling is designed to minimize spillage and damage associated with drive away and pull away incidents.  Provides protection against situations where a hose or loading arm could be subjected to excessive loads  Coupling automatically senses an excessive load, closes the valves and disconnects  Operates independently of shut off safety systems and does not require an external power source  High flow rate with low pressure drop  Female NPT, Male NPT, ANSI/DIN flanges or any combination of flange or thread  Standard seals are Viton®  Available in sizes 1, 2, 3, 4 and 6”  Material 316 Stainless Steel, Brass & Aluminum

7 Safety Break-away Couplings Industrial break-aways are typically installed on a loading arm or manifold and hose assemblies, where at least one side of the coupling is attached to a rigid or fixed point. Release with a tensile force being applied at an angle to the plane of the coupling housing, up to 90 degrees.

8 Break Forces The SB Couplings dry break-away couplings has three external breaking 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. Non-axial forces concentrate the tension forces more strongly on one bolt, so that the breakaway coupling reacts to the reduction of the hose break forces. The break forces are transferred directly to the breaking bolts up to 90 degrees from hose center Size Industrial 1” 4 2” 13 3” 33 4” 52 6” 92 Tension Forces in kN Safety Break-away Couplings

9 Marine Version Safety Break-away Couplings Marine break-away couplings are designed specifically to be installed within a hose string between two lengths of hose. This coupling incorporates the same internal mechanism as the Industrial couplings, but has additional features that provide increased resistance to torsional and bending forces which may be applied to the coupling. This make the coupling react only to tension in the hose string and preventing premature activation in the unpredictable marine environment. MSBC400SS

10 Marine Version The breaking bolt marine version break-away coupling is designed to minimize spillage and damage associated with pull-away incidents.  Typical applications include: ship-to-offshore platform and ship-to- ship product transfer operations  Designed to be installed in a hose string where the coupling will be installed between two length of hose  Coupling automatically senses an excessive load, closes the valves and disconnects  Release is executed when force causes bolts to break  Standard seals are Viton®  Female NPT, Male NPT, ANSI/DIN flanges or any combination of flange or thread  Operates independently of shut off safety systems and does not require an external power source  High flow rate with low pressure drop  Available in sizes 2, 3, 4, 6 and 8”  Material 316 Stainless Steel, Brass & Aluminum Safety Break-away Couplings

12 Safety Break-away Couplings Marine safety break-aways are designed to only release by inline pull and used between two strings of hose. Release with a tensile force being applied to the hose string exceeds the tensile strength of all three bolts.

13 Break Forces The MSB Couplings dry break-away couplings has three external breaking 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. Non-axial forces is minimized by an internal flange mechanism that provides increased resistance to torsion and bending forces which may be applied to the coupling in a marine application. The break forces are transferred to the breaking bolts through the hose string. When the force on the breaking bolts exceed their design load, the bolts break and allow the valves to seal and separate.

14 How It Works The Safety break-away couplings consist of two halves, each with a valve that has a flat type- sealing surface similar to a dry disconnect coupling. When the force on the breaking bolts exceed their design load, the bolts break and allow the valves separate. The coupling automatically senses an excessive load, closes the valves and disconnects. When the SBCouplings separate, it allows the poppets to close. The two poppets close rapidly, minimizing product loss. Safety Break-away Couplings

18 Non-Closure Version Safety Break-away Couplings The non-closure design acts purely as a safe parting point within the transfer system, protecting equipment and personnel. With no internal mechanism these couplings are utilized when the product is non- hazardous and spillage is acceptable. Such as a water supply line.
