Riddhi Siddhi Impex focuses on precision coating technology to ensure uniform application and excellent adhesion of the cement mortar. The company’s modern production facility is equipped with advanced machinery for cleaning, coating, curing, and testing, ensuring consistent product quality and reliability for every project..

The manufacturing process of Cement Mortar Coated Pipes by Riddhi Siddhi Impex involves several meticulous stages. The steel or ductile iron pipes are first thoroughly cleaned to remove contaminants, rust, or scale. The internal and external surfaces are then coated with a specially prepared mixture of cement, sand, and water in controlled proportions. The coating is applied centrifugally or by spray methods to achieve uniform thickness and bonding strength. Once applied, the coating undergoes curing to achieve optimum hardness and durability. The resulting pipes provide robust resistance to abrasion, corrosion, and chemical attack, making them suitable for transporting potable water, wastewater, and industrial fluids..

Cement Mortar Coated Pipes (Internal & External) from Riddhi Siddhi Impex offer numerous advantages. They provide excellent resistance to electrochemical corrosion, which commonly affects steel pipelines buried underground or submerged in water. The smooth interior surface reduces friction losses, ensuring efficient fluid flow and energy savings in pumping systems. The external coating provides an additional layer of protection, especially in saline or chemically aggressive soils, making these pipes ideal for coastal, industrial, and municipal projects. Moreover, they are environmentally friendly as the coating materials used—cement and sand—are natural and non-toxic..
