Luleh va Mashinsazi Iran (LMI Co)
with more than sixty years of experience in production and development

So far, water transportation and sanitation have always been ofinterest to developing countries, and this importance is twice for low water areas such as Iran and the Middle East. These areas require a large water distribution network, and the pipe is the most important part of that. Over the years, relevant Iranian organizations had bought and used ductile iron pipes, which are the best option for the health ofdrinking water, from European and American countries and used in distribution network. LMI Co., with the aim of eliminating the dependence to foreign countries and supplying some of the equipment used in the water industry, has started its activities since 1957 and during the more than sixty-five years, has been as a pioneer of this industry and supplier of Ductile Iron Pipes and Fittings (with the same quality as the best global manufacturers).
Currently, LMI Co. in Tape Sefid and Shams Abad factories,produce ductile iron pipes with a diameter from 100 to 2000 mm and an annual capacity of 140,000 tons in accordance with the latest international standards, which in addition to domestic demand has also covered the export markets of the region.

Advantages of Ductile Iron Pipes: 
:: High corrosion resistance
:: Long lifetime
:: High value of scrap
:: Desirable mechanical properties (tensile strength, elongation and high buckling strength)
:: Suitable for applications with high stress and high surge pressure because of its high strength,  excellent elastic properties and ductility
:: High resistance to traffic loads and land slide
:: High impact resistance
:: Insensitivity to ovality in compare with other pipe types
:: Less Sensitivity to trench preparation
:: Proper angular and longitudinal displacement
:: High installation speed (atmospheric agents have less effect on the installation of ductile iron pipes)
:: Ability to cut and branching if necessary
:: Not sensitive to sunlight and UV rays
:: High resistance to human and plant factors
:: Insensitivity to temperature
:: High hydraulic flow coefficient (due to the internal cement lining with centrifugal method)
:: Low maintenance costs (no need for cathodic protection)
:: Less pumping costs due to a larger nominal diameter and a high coefficient for hydraulic flow
:: Traceability using metal detectors
