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.

Features:

In addition to reliable performance, B-303 pipe offers system owners several benefits including: cost efficiency in terms of materials, handling, and installation, plus the inherent corrosion protection provided by combining steel with Portland cement mortar. A major feature of B-303 pipe is its lighter weight, which offers the advantage of shipping more pipe per truckload. B-303 also offers rugged durability, minimal maintenance, and long service life—that all ads up to excellent value for your pipeline investment. 

B-303 pipe is considered to be a modified version of mortar-lined and mortar-coated steel pipe with the exception that B-303 provides superior mortar coating bonding and corrosion resistance qualities. A key advantage is that it allows for easy modifications in the field, such as adding a manhole outlet, making service taps, and performing simple repairs should the pipe be damaged.
