B-303 pipe from Forterra is manufactured using a welded steel cylinder lined with centrifugally-applied mortar or concrete; a mild steel reinforcing bar is then helically wound around the outside of the cylinder and coated with dense Portland cement mortar.
B-303 pipe from Forterra is manufactured using a welded steel cylinder lined with centrifugally-applied mortar or concrete; a mild steel reinforcing bar is then helically wound around the outside of the cylinder and coated with dense Portland cement mortar. This composite construction combines the best of both materials — the strength of steel with the corrosion resistance and durability of concrete and mortar. The completed pipe is able to withstand internal pressures and external loads normally encountered in the waterworks industry. The design allows for easy modifications in the field, such as adding a manhole outlet, making service taps, and performing simple repairs.
