Pipe mill
Oerlikon teams are ready to respond in collaboration with the pipe mill to provide technologically relevant and practical solutions.
SAW wires and fluxes selection
A selection of the most important welding consumable products for both longitudinal seam and spiral seam pipe welding are shown below, based on industry custom and practise.
SAW wires features:
- Conformance to Oerlikon specifications and national standards where specified
- Optimised chemical alloying to maximise joint toughness
- Low levels of residual and impurity elements
- Closely controlled copper coating
- Consistent performance through control of: Wire hardness - Cast - Helix
- High productivity bulk packaging options
- Full range of diameters available, 2.4 - 5.0 mm
On pipe mill market the most used Oerlikon submerged arc fluxes are:
- OP 119, OP 192P & OP 132.
OP 119 is widely used for spiral seam welding - OP 192P & OP 132 are used for both two pass longitudinal seam and spiral seam
welding applications. These fluxes are optimised for high productivity performance in multi-wire, AC/DC, high welding speed pipe welding applications. - OP 121TT & OP121TTW are used in multi pass and special applications, particularly when maximum joint toughness at higher strength levels is required.
The Oerlikon range of submerged arc fluxes is very comprehensive and for specific pipe welding applications other SAW fluxes may be proposed by Oerlikon technical service, for example OP 122 and OP 178.
