MannTek Safety Breakaway Couplings

MannTek Safety Breakaway Couplings

Used to protect hose assemblies and loading arms against excessive loads, e.g. due to drive/pull away incidents or rapid removal of the mobile tanker in emergency situations.

Typical applications include container discharge, fuel bunkering truck-to-ship, ship-to-ship, terminal-to-ship, loading/unloading of tank trucks, rail tankers & ships.

SBC 'Industrial Type' have three external breaking bolts. Breaking forces (release forces) are calculated on the basis of the working pressure of the system.

• Sizes range from 1" (DN25) up to 12" (DN300).
• Connections are BSP/NPT thread, DIN/ANSI/TW/TTMA flange - others on request.
• Working Pressure - Aluminium 16bar, Stainless steel 25bar, Brass 16bar.
• Temperature - between -20°C up to +80°C.
• Material - Body: either stainless steel (1.4401 [AISI 316], 1.4404 [AISI 316L], 1.4408 [CF-8M], 1.4409 [CF-3M]), aluminium - others on request. O-Rings: Viton® (FPM/FKM) - others on request. Flat seal (for female parallel thread connections only): PTFE (stainless steel couplings), PU (aluminium and brass couplings) - others on request. Breaking bolt types: breaking bolts of stainless steel. 
• Approvals / Certificates: SBC fulfil the requirements of European Pressure Equipment Directive category 2 (for higher demand on request). They are suitable for the use in potentially explosive atmosphere (ATEX) zone 1, approved for the transport of dangerous goods on road (ADR), by rail (RID) and by ship (IMDG).
