Bar-Wrapped Concrete Cylinder Pipe (AWWA C303)
Forterra’s Bar-Wrapped Pipe (BWP) combines the strength of steel with the corrosion resistance and durability of concrete.
Bar-wrapped concrete cylinder pipe is manufactured in accordance with AWWA C303 standard and is designed in accordance with AWWA Manual M9. C303 pipe is manufactured using welded steel cylinder with sized, welded steel joint rings attached. The pipe interior is lined with centrifugally applied mortar or concrete 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 cement-rich dense mortar is applied to the cylinder and bar wrap. The mortar coating on the pipe creates a passivating alkaline environment that protects the steel cylinder, joint rings and bar from corrosion.
Size: In diameters from 400mm to 1500mm in std lengths of 7.315m
C303 Features:
In addition to reliable performance, C303 pipe offers system owners several benefits including: cost efficiency in terms of materials, handling, and installation. A major feature of C303 pipe is its lighter weight, which offers the advantage of easier tunnel installations. C303 also offers rugged durability, minimal maintenance, and long service life—that all adds up to excellent value for your pipeline investment.
C303 pipe is considered to be a modified version of mortar-lined and mortar-coated steel pipe with the exception that C303 provides superior mortar coating bonding and corrosion resistance qualities.

ASSOCIATIONS
Forterra Pipe & Precast are proud members of the American Concrete Pipe Association (ACPPA). Founded in 1949, the American Concrete Pressure Pipe Association (ACPPA) is a nonprofit trade association representing manufacturers of concrete pressure pipe around the world. ACPPA sponsors research projects and conducts educational programs to promote and advance the use of concrete pressure pipe in water and wastewater applications.
ACPPA manages an independent audit program to certify compliance with all applicable AWWA standards for the design and manufacture of concrete pressure pipe. The ACPPA Compliance Audit and Certification Program, administered by Lloyd’s Register Quality Assurance (LRQA), is much more than an observation of the final product.
