DRYBAG - Submerged arc fluxes
DRYBAG from Oerlikon reduces costs, time and energy
The fabrication specifications of oil companies and power suppliers usually require a guaranteed very low level of SAW flux moisture in order to attain a diffusible hydrogen level of less than 5 ml/100 g in the deposited weld metal.
These specifications clearly stipulate the conditions required to guarantee compliance with this requirement.
The research and development and the production departments of the Air Liquide Welding group, have developed an innovative new packaging system for Oerlikon submerged arc welding fluxes: DRYBAG a fully moisture proof packaging system making any requirement for flux conditioning unecessary, resulting in high-quality welds even in the most hostile ambient conditions.
DRYBAG is made of an advanced polyethylene-aluminium composite foil, specially developed for vacuum packaging applications. For enhanced security, a partial vacuum is produced in the DRYBAG during the packaging of the welding flux. The low-pressure serves as an indicator for the security of the packaging. Oerlikon DRYBAG offers similar levels of security as packaging in metal drums, but is more cost effective. DRYBAG is available in 25 kg or larger, 800 or 1000 kg formats. The 25 kg-DRYBAG can be stored, transported and palletised in the same way as regular 25 kg bags and the larger formats have an integral pallet.
Advantages
DRYBAG - Submerged arc fluxes
No risk of moisture ingress, even during transcontinental or maritime transport and following long-term storage in adverse conditions. No risk from ambient humidity, even in extreme climatic conditions, such as Africa, Brazil, Argentina, Asia etc. No need to re-condition the flux before use. This new packaging solution enables the fabricator to reduce the risk of hydrogen induced cracking. No requirement for detailed control of temperature or humidity during storage, thereby saving time and energy costs. Improved, simplified handling and storage compared to existing solutions using metal drums, again reducing costs..
