CO2 System

With a 45 year experience in the Marine industry we are able to understand and comply with the important safety regulations that are implemented from time to time, and what they mean for ship owners and operators. These important regulations include the replacement of CO2 hoses according to IMO Regulation MSC.1/Circ.1318 Guidelines for the Maintenance and Inspection of Fixed Carbon Dioxide Fire Extinguishing Systems 6.1.2: “Flexible hoses shall be replaced at intervals recommended by the manufacturer, up to every 10 years” . Depending on the quality of CO2 hoses and their fittings, they are usually very strong, but can deteriorate, and when this happens, the consequences can be severe. A leaking hose can have fatal consequences. We, as a HANSA-FLEX certified assembly center, are very sensitive to everything that safety and human life depend on, which is why we use high quality and certified hoses that are SAE 100R7, MSHA Standard and Lloyd Registered Type Approved.

Technical characteristics: 

• Technical-constructive features: Inner core consists resistant synthetic rubber, reinforcement between inner and exterior core consists two high-tensile steel wire braids and exterior covering consists synthetic pin – pricked rubber which lets trapped gases escape from the hose casing. Without pin pricks, bubbles or blisters would start to appear in the cover of the hose. The HANSA-FLEX CO2 hoses are:
• Resistant in environments having high humidity, low or high temperatures and saline levels.
• Stabilized against UV rays
• Microorganisms-resistant
• Micro perforated for gas conduction
• Applications: Hoses of the CO2 SYSTEMS series have been created for CO2 fire extinguishing medium pressure systems in MARINE environments.
• Working temperature: From -40°C to +100°C from -40°F to +212°F.
• Max. working temperature of air, water and water-based fluids is + 70°C (+158°F).
• Working pressure: Safety ratio 1:4
• Vacuum rating: 0.93 bar; 700 mm Hg
• Elongation: From + 2 % to - 4 %
• Specifications: All hoses meet or exceed SAE J517 sect. SAE 100R7 – ISO 3949 - 1402 – MSHA Standards and Lloyd’s Register TYPE APPROVAL
