Market Trends change
Being a Global Trader of such a variety of machinery, the last 6 months we have witnessed fluctuations in many Industries.
If you are involved in orbital TIG welding – are times changing?
Tube to Sheet Welding
Food and Beverage / Pharmaceutical / Chemical/Sanitary Industry
Hygienic requirements and resistance to corrosive media under pressure and temperature
The final product must not be affected by contamination or microbial growth. The orbital welding guarantees:
- Reproducible, pure welds for optimum resistance against microbiological influenced corrosion
- Smooth welds for easy cleaning to meet the hygienic requirements
- Controlled and constant penetration
- Minimized heat input in the heat affected zone
- Minimized oxidation
- Metallurgical superiority
- ISO documented weld quality
- Gain of time thanks to reduced testings (non-destructive/destructive testing)
- Automatic documentation of the welds within integrated quality management systems
- Tube O.D.6,0 – 220 mm
- Wall thickness0,8 – 3 mm
- Material304 and 316 L type stainless steel
Thermal Transfer Equipment / Heat Exchangers
Heat exchangers are widely used in many ways and are seen in many types of industrial, commercial and residential applications. Heat exchangers come in many configurations, sizes and materials of construction. Some of the various types of heat exchangers are shell and tube, plate coil, pipe coil, bayonet and air finned tube.
High productivity with zero default rates
For sterilisation in food processing, heat exchanger fabrication for power generation, air cooler production.
Materials: Carbon – stainless steels and related alloys, Titanium, Zirconium, Duplex.
For more details follow link to used Polysoude orbital weld head or Polysoude P6 power supply
- Compatible for work with all series of Polysoude power sources: xx4 series without AVC; xx6 and PC series with AVC.
- Various toolings are available to accommodate with all existing tube joint designs.
- Interchangeable I.D. related, flexible centring mandrels to comply with standard tube tolerances.
