Why is ductile iron pipe cement lined

Cement mortar has good abrasion resistance, which allows the pipes to be used for carrying raw waters with high abrasive particle content.

Please consult us for these applications. EN Ductile iron pipes, fittings, accessories and their joints for water pipelines. Requirements and test methods. ISO Centrifugal cement mortar lining. General requirements. You are here Home Cement mortar lining. Cemar mortar lining The standard internal protection for PAM pipes consists of a cement mortar lining. Application The cement mortar lining is applied by a centrifugal process. The process gives the following properties: high mortar compaction, low roughness, good mortar key.

Depending on the characteristics of the fluid, the requirements of this protection vary and therefore its behavior will be different. Nowadays, we find special formulated cements for specific applications that face different problems. However, there are also mechanical protection coatings and linings that face these same problems with a different philosophy and that we will discuss in an incoming article.

Articles Why is cement mortar applied as an internal protection against corrosion in ductile iron pipes? By Construtec December 18, No Comments. Industrial Fire World. Cement-mortar lined ductile cast iron pipe. Conclusions So the use of a cement mortar lining in a grey cast iron pipe ductile cast iron pipe nowadays intended to protect it versus the attack of the water carried; a protection that works as a chemical alliance between cement, iron and the water.

However, there are also mechanical protection coatings and linings that face these same problems with a different philosophy and that we will discuss in an incoming article For further technical details about cement mortar lining benefits, please contact with info construtec. Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe. Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs.

NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream. NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system.
