Section 3 Buttweld - AAP Industries

1 47 Edition 3 Section 3 Buttweld48 [3] BUTTWELDS pecificationsAAP stocks Buttweld 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.
