Raw Materials:

The vitrified clay pipes & fittings are produced from three major raw materials in which two Red Clay and White Clay are quarried from the parent company quarries whereas the third component “Chamotte” is recycled from in-house broken pipes.

Raw Materials Preparation:

CPC has a highly technological automated process developed and supplied by Italian and German suppliers to blend all the three types of raw materials (Red Clay, White Clay & Chamotte) in suitable particles sizes and mixed up in appreciating proportions. To achieve the plasticity necessary for the shaping of pipes, water is added as per required percentage.

The shaping of Pipes:

Subsequently, the mixed clay sent to an extrusion process for the shaping of pipes through highly technologically developed automated extrusions machines made in Germany and Britannia to extrude different sizes of nominal diameters. The extruded pipes are placed on dryer cars.


Subsequently, the shaped pipes are pushed into the dedicated fully automated Italian dryer channels for drying process where the temperature ranges from 70-100 degrees.

Glazing and Setting:

Subsequently, the dried pipes are inspected for quality and the good pipes dipped into the glaze tank for glazing and loaded on Kiln Cars. The load cares moved to the pre-kiln dryers to remove the moisture content of glaze.


The kilns cars pushed into the fully automated Shuttle Kiln or Tunnel kiln for the process of vitrification where firing temperature of gradually increases until it reaches it’s maximum of 1,200 degrees and then gradually decreases which resulted totally a new material consisting of high degree of glass and other ceramic materials.

Final Inspection:

The pipes which are coming out from Kilns are unloaded and inspected to ensure compliance with the standards. The pipes which do not comply with the standards are sent for crushing to use a Schamotte as a major component of raw materials. Various quality tests are done after final inspection to ensure the quality and specifications compliance according to the required standards.

CPC Pipes and fittings comply in all ways with the stringent requirements of SASO/GSO/EN 295-2008 and EN295.

Sealing / Joints:

CPC used highly developed technology supplied by Germany and the imported German polyurethane materials for the sealings of K (C) joints System.


The Vitrified Clay Pipes are packed in bundles or pallets by using a wooden base and spacers to make up separated layers of pipes, held together by steel bands, ensuring that socket spigot ends do not touch each other or the ground surface. The fittings packaging depends on its weight and shape. They are usually delivered on wooden flat pallets or in wooden box containers.
