Cement Mortar Lined Steel Pipe. Imperial produces quality linings per AWWA standard C205, API practice 10E, or per your Customspecified mix. A durable, costeffective, timeproven choice for protecting steel pipe interiors for over a Century. Appropriate for above or belowground applications in potable and reclaimed water systems.
Cement mortar lining can ensure a safe and abundant water supply for your water customers for many years to come. Cement will also extend pipe life by inhibiting the corrosion of ferrous materials and preventing future rust and tube regulation build up.
AMERICAN Linings for Pipe and Fittings. Cementmortar lining for ductile iron pipe and ductile and gray iron fittings for water service is in accordance with ANSI/ AWWA C104/ Cementlined pipe is also furnished for some sewage service and a number of other applications. In fact, most pipe furnished is cement lined, providing improved flow characteristics and the required protection against internal
Application. SG14#174; for the lining of ductile iron and steel pipe and fittings. Typical Uses. As a deterrent to interior buildup, clogging, wear, and corrosion in high solids and grease systems. Includes sludge, scum, and screened grit piping and related equipment.
Cement lining is a process by which steel pipe and fittings are coated internally with cement mortar. This process combines the physical strength of steel with the protective qualities of cement mortar. The lining is applied centrifugally to pipe, creating a smooth finish the length of the pipe.
Cement Mortar Lined and Coated Steel Pipe. Durable and inexpensive, Cement Mortar protects and strengthens buried steel pipe for longterm service. Once again, cement coatings have been reliably used for well over a century and we expect theyll continue to be used long into the future.
and cement lined in accordance with ANSI /AWWA C104. ANSI /AWWA C104. Standard or double thickness as required. The exterior of the underground pipe will be coated with asphalt tar in accordance with ANSI /AWWA C151. All coating and lining for exterior piping, and all lining for interior piping, is certified to be in compliance
Nov 14, 2007#0183;#32;The refurbishment of buried cast iron and steel pipes with the cement mortar lining is a standardised, technically mature, proven and recognised procedure. Fields of application The internal lining of pipelines is a method preferentially used for the refurbishment of drinking water pipes made of ferromagnetic materials (cast iron, steel).
Coating mortar lined pipes are centrifugally lined at the factory to assure that the best possible quality control is maintained and that a uniform thickness of mortar is distributed throughout the entire length of pipe. Cement linings prevent tuberculation by creating a high pH at the pipe wall, and ultimately by providing a physical barrier to the water.

Jan 16, 2016#0183;#32;Cement Lined Pipe is pipe that is internally coated with a mortar like compound that acts as a barrier between the carbon steel pipe and the process. The lining may be applied by hand, as is the case with pipe fittings, or with a machine. It is commonly used in the transmission of potable water and sewage applications.
A. Mortar lined and enamel coated steel pipe shall conform to SSPWC subsection 20710, subject to the supplementary requirements indicated herein. Mortar lined steel pipe shall conform to ANSI/AWWA C200, C203, C205 and C208, subject to the following supplemental requirements.
After the joint configuration is completed and prior to lining with cementmortar, each length of pipe of each diameter and pressure class shall be shoptested and certified to a pressure of at least 80 percent of the yield strength of the pipe steel.

The Cement Lined Steel Pipe or the Cement Mortar Lined Steel Pipes are common in carbon steels. The application of the Cement Lined Carbon Steel Pipe reduces the cost by eliminating the need for anticorrosive pipes but it increases the risk of cracking of cement during handling.
Cement Mortar Lining of the internal surface of steel pipe are highly durable, with records showing pipes still in service after 100 years in municipal and water service life. This durability is achieved by mixing the mortar such that the pores within its structure are highly alkaline, making the lining resistant to the growth of bacteria, which can affect other types of lining.
