VWA stocks Buttweld fittings which are made from high quality carbon alloy steel to ASTM A234 which can be used in various piping systems.
The advantages of Buttweld include:
- Welding a fitting to the pipe means it is permanently leak proof
- The continuous metal structure formed between pipe and fitting adds strength to the system
- Smoother inner surface and gradual direction changes reduce the pressure losses and turbulence and minimises the action of corrosion and abrasion
- A welded system utilises a minimum of space
Used in industries:
- Oil & gas
- Irrigation
- Plumbing
- Waste Water
- Power Generation
- Fabrication
