Apr 13, 2023 · Aggressive water penetrated the pinholes in the bituminous inner surface, and internal corrosion in the form of tuberculation occurred. Tuberculation is a bacterial-based oxygen-driven form of corrosion that results in iron oxide precipitation.

Oct 6, 2020 · You shouldn’t have to live with restricted flow caused by a tuberculated pipe. Learn about tuberculation in cast iron pipes and how to clean & prevent buildup.

Left untreated, a tuberculated pipe can disrupt a pipe’s flow. Learn what causes tuberculation, how to prevent it and APS’ tuberculation removal process.

Jul 19, 2024 · Tuberculation is the development of small mounds of corrosion products on the inside of iron pipes. These mounds are reddish brown and of various sizes. This phenomenon generally happens in domestic water distribution systems …

American Pipeline Solutions’ pipe descaling process is an ideal alternative to replacing your tuberculated pipes. To properly clean your pipes, APS first will perform a visual inspection to determine the pipe buildup level.

Feb 11, 2019 · UDF is an effective method for clearing debris and other unwanted material from pipe mains; thus, enhancing water quality, reducing turbidity and improving chlorine residual. UDF is performed by isolating the flow of water in the distribution network to a particular pipe by closing specific valves. Hydrants at relevant locations are then opened ...

Sep 22, 2017 · Tuberculation is the formation of mounds of reddish-brown iron-oxide on a pipe’s interior. This phenomenon is classified as a type of bacteria-driven corrosion and is typically associated with older iron pipes. Tuberculation is caused by the action of …

Jul 20, 2020 · When tuberculation occurs in pipes, it can restrict the flow of water through the line and create sediment deposits and deplete chlorine. A biofilm can also form due to the bacteria eating away at the cast iron of the pipes. A first indicator that …

Laboratory studies indicate the inter related influences of chloride, alkalinity, pH, calcium, silica, and free and combined chlorine on the corrosion of steel and cast iron by water. Free chlorine was found to be corrosive to steel in water of Great Lakes quality.

Pipe Materials: Using non-corrosive materials like copper, PVC, or stainless steel can prevent tuberculation. Internal Coatings: Applying protective coatings to the interior surface of iron pipes can prevent direct contact with water, reducing corrosion.
