Bar-Wrapped B-303

Hanson’s Bar-Wrapped Cylinder Concrete Pipe combines the strength of steel with the corrosion resistance and durability of concrete. Bar-Wrapped pipe is ideal for transmission mains, distribution feeder mains, treatment plants, intake and discharge lines, plant piping and other applications. Diameters from 10 to 72 inches (14 to 20 inches in Canada) and design pressures up to 400 psi are produced. Depending on location, we manufacture in lengths of 20 to 35 feet. Bar-wrapped concrete cylinder pipe is manufactured in accordance with AWWA C-303 standard and is designed in accordance with AWWA Manual M9.  

B-303 pipe is manufactured using welded steel cylinder with sized, welded steel joint rings attached. The pipe interior is lined with centrifugally applied mortar lining. A steel bar is helically wound tightly around the outside of the cylinder and securely welded to the steel joint rings. A coating of dense mortar is applied to the cylinder and bar wrap.
