Retrieved 18 October Mixed results have been found for all methods of protection. The ductile iron pipe pdf download environment for which the analysis found the polyethylene sleeving did not provide effective corrosion control was for “uniquely severe” environments, a classification of ironn rare but extremely corrosive environment. This type of joint restraint is generally labor intensive.

American Water Works Association. The predominant form of lining for water applications is cement mortar centrifugally applied during manufacturing.

European pipes are sized to approximately match the internal diameter of the pipe, following internal lining, to the nominal diameter. Polyethylene sleeves are available in a number of materials. This is roughly equivalent to the ductile iron pipe pdf download internal diameter in inches or millimeters.

Ductilf most modern is the ‘push-joint’ or ‘slip-joint’, whereby the socket and rubber seal is designed to allow the pipe spigot to be, after lubrication, ductile iron pipe pdf download pushed into the socket. Repair is achieved doqnload first cutting out the defective or damaged lining to the metal so that the edges of the lining not removed are reasonably perpendicular to the pipe wall or slightly undercut.

It provides a homogeneous environment along the pipe surface so that corrosion occurs evenly over the pipe. Also available are locking gasket systems. This page was last edited on 15 Novemberat Consequently, the internal diameter varies, sometimes significantly, from its nominal size.
