Which pipe type matches the description of steel cages of welded wire fabric with helically wrapped rods?

• A. PVC pipe
• B. Reinforced concrete noncylinder pipe
• C. Steel pipe
• D. Cast iron pipe

Answer: (B)

This describes reinforced concrete noncylinder pipe. The steel reinforcement cage, formed from welded wire fabric with helically wrapped rods, provides the hoop strength around a non-round shape, and concrete is poured around it to make the pipe. This combination matches RCNP, distinguishing it from PVC (plastic with no steel reinforcement), steel pipe (metal without a concrete envelope), or cast iron pipe (iron with no welded wire fabric reinforcement).
