TYPES OF PIPE

METALLIC PIPE

Cast iron

Cast Iron Pipe

Cast iron (grey cast iron) is a historical type of pipe manufactured in the 19th and 20th centuries that is used as pressure pipe for transmission of water and sewage. Cast iron pipe was gradually superseded by ductile iron pipe, which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s.

Ductile iron

Ductile Iron Pipe (DIP)

Introduced in 1955, ductile iron pipe is a direct development of earlier cast iron pipe which it has superseded. Ductile iron has proven to be a better pipe material than cast, being stronger and more fracture resistant; however, like most ferrous materials, it is susceptible to corrosion and retains some brittle characteristics.

Steel pipe

Steel Pipe

The first methods for producing steel pipe were introduced in the early 1800s, and they have steadily evolved into the modern processes we use today. Large diameter steel pressure pipes for water and wastewater applications are typically made with carbon steel and installed as buried assets.

Prestressed Concrete Cyclinder Pipe (PCCP)

Prestressed Concrete Cylinder Pipe (PCCP) was first manufactured in 1942 as lined cylinder pipe. This pipe, constructed by welding steel joint rings to a steel cylinder, was then coated internally with concrete. The outer surface was wrapped with high strength steel wire directly over the steel cylinder and covered with a cement-based mortar coating.

BAR WRAPPED PIPE C303

Bar wrapped pipe

Bar Wrapped Pipe (BWP)

BWP is very versatile and is well-suited to projects requiring a pipe diameter of 24 to 72 inches, with a working pressure of 300 PSI or less.
