THE INTERNATIONAL COMPANY FOR STONEWARE PIPES AND CERAMICS
About Us

The International Company for Stoneware Pipes and Ceramics (CIPAC) was established in 1981, to produce glazed Vitrified clay pipes and fittings from 100 mm up to 1000 mm with flexible joints for drains And sewers to contribute with this production in the sewers operating on gravity in Municipal and industrial applications as CIPAC is a leading company in this industry in the Middle East. Compliance with the requirements is monitored and recorded by the internal quality management system to quality certificate ISO 9001:2008, Environmental Friendly Certificate ISO 14001:2004 and Safety and Occupational Health Certificate OHSAS 18001:2007.

CIPAC pipes are manufactured according to the Egyptian standard 56 -2005, European standard EN 295, which specifies requirements for vitrified clay pipes and fittings with flexible (rubber and polyurethane) joints for drains and sewers.



Features of our CIPAC pipes

Clay pipes resists the Biological induced H₂S corrosion, resist the chemical attack in a pH-range for special circumstances or application, the Mechanical resistance has developed enormously during the last decades, resistance the high-pressure cleaning considerably is better than many other types of material, have and hold a smooth inner surface, Especially in the case of limited slopes, this offers quite some advantages. Because of the high erosion resistance, can even be used for slopes up to 10 m/sec., without any danger of material deterioration, Vitrified clay is the only material that resists regular rinsing and unclogging by means of high water pressure techniques. This means that vitrified clay pipe canals can be written down (off) over a longer period and that maintenance, renovation and replacement costs can be limited to a much lower level, Vitrified clay has high abrasion resistance which is equally true for the glaze and the rest of the wall and resistant to all types of chemicals over the entire wall thickness, also has a low heat expansion coefficient and Environmental friendly.


CIPAC annual capacity is around 35 thousand tons, pipes length from 1.5 to 2 meters, pipes diameters from 100 mm up to 1000 mm, produced according the project specifications.


Properties of Vitrified Pipes

Vitrified clay pipes and fittings are produced from the raw materials clay, grog and water. The glaze applied to the products before firing consists of mainly the same basic components plus metallic oxides for color. During drying most of the water necessary for shaping is extracted. The subsequent firing at very high temperatures creates a completely new material by sintering.

This vitrified clay has exceptional properties in respect to chemical resistance, mechanical strength, impermeability and hardness.Highly developed manufacturing and preparation techniques have made it possible to upgrade an already proven product, the consistency is guaranteed by quality control system according to Quality Certificate ISO 9001:2008, Environmental Friendly Certificate ISO 14001:2004 and Safety and Occupational Health Certificate OHSAS 18001:2007.

Vitrified clay pipes are designed for sewers operating on gravity in municipal and industrial applications.

CIPAC pipes are manufactured to a harmonized standards which specifies requirements for vitrified clay pipes and fittings with flexible joints for drains and sewers.


Biological Induced H₂S Corrosion

The formation of H₂S in sewage is a consequence of the natural biological decomposition of sulphur containing organic and inorganic matter.H₂S mainly forms under anaerobic conditions by sulphate reducing bacteria in the slime of a matured sewer and to a lesser extent by bacteriological processes in the sewage.In gravity sewers the formation of H₂S commences after the oxygen originally present in the sewage has been consumed by manifold biological processes.This is followed by the anaerobic decomposition with an ever increasing formation of H₂S, which slowly escapes into the sewer atmosphere.Turbulence in the sewage stream increases the escape of the gaseous H₂S.The formation of H₂S is supported by long sewage flows, low flow velocities and high sewage temperatures.
