1 INTRODUCTION

1.1 INTENDED USE

This guide for safety breakaway couplings SBC is intended for operators and planners of tankers and tank

systems as well as for hose assembly workshops and hose assembly workshop maintenance engineers. The

safety breakaway coupling acts as a safety component in the supply line of mobile refuelling systems,

preventing damage to the environment whenever the supply pipe bursts during filling or emptying due to a

change in location of the tank. The coupling valves on the tank and on the supply line immediately close

whenever the housing halves break away.

SBC safety breakaway couplings of MannTek include special features:

• High quality processing

• Sturdy design

• Low wear

• Tamper-proof

• Safe operation

• Release angle up to 90° through two pressure

clamps on activation mechanism

• Maintenance-friendly

• Wide spectrum of application

1.2 RANGE OF APPLICATIONS

Industrial

• Plant engineering

• Power plant construction

• Chemical industry

• Food processing industry

• Process technology

• Tank cleaning

Media

• Lyes and acids

• Fuels and oils

• Gases

• LPG/ LNG & CNG

• Materials hazardous to

the environment and

water

Filling systems

• Airfields

• Railroads and wagons

• Tank trucks

• Ships

• Tank containers

• Liquefied gas
