Pipe Application / Egypt - "Primary care families"

Krah New Mena plastic





With approximately 8 million people Cairo (Egypt) is the most populous city in the Arab world. Today the metropolitan area of Cairo is even home to around 25 million people, which means that the provision of clean drinking water and disposal of wastewater is one of the biggest challenges of this region. To address this problem the government has embarked on the project "Primary care families", some time ago. This project aimed to support people, "who had lost their homes in catastrophes or who lives in very bad conditions."

ATV A127 Standard vs. AWWA M55 manual


Main Differences in the Static Calculation Methodology for Flexible Pipes


The purpose of this article is to set up the main differences between two popular methods worldwide for performing static verifications of HDPE flexible pipes, i.e. between the method given by the ATV A127 standard ("Guidelines for Static Calculations on Drainage Conduits and Pipelines") and the method established by the American Water Works Association (AWWA) more specifically in its manual M55 ("PE Pipe Design and Installation").

Storage tanks and special apparatus

Tanks for storage of liquids are required in all areas of public life. Constructions made of thermoplastic plastics are playing a decisive role on this. Beginning with the traditional bucket, which are belonging to our lives since the earliest initiations of plastics technology, up to the 100 m³ storage tank for chemicals and hazardous liquids – there is no way of avoiding constructions made of polyethylene and polypropylene today. Particularly if the cylinder barrel is made of helical extruded pipes, the flexible wall construction (profiled wall structure, multi layer, etc), which comes along with the manufacturing method, in connection with new generations of raw material, continuously opens up new possibilities of solution for the construction of tanks. Thereby new possibilities to connect stability, resistance, long-life cycle and chemical resistivity as well as cost-effectiveness are established. This makes it possible to incorporate them suggestively into construction.

A multitude of tanks is engineered in vertical form. The bottom construction is carried out as flat, beveled or conical bottom. The roof construction in turn can be engineered open – with or without reinforced edges, with cone-type roof or with flat roof.

Krah AG re-structured range of products

From now on the German Krah AG re-structures its complete range of products. The goal is to offer project-based high-performance machines up to complete pipe work, besides a universal discounted entry-level machine (especially suited for emerging markets) - All from one source and modular extendable.

The principle: Start small, without ruining the future. The new complete product catalog incl. new prices will be available in January 2012.          

As of 01/01/2012 Krah AG passes the complete spare parts business (incl. sales of equipment for Krah pipe systems) to the KHB GmbH in Cologne. The external process will accelerate the procurement of spare parts and lower selling prices, so that maintenance can be done in due time at the customer's schedule. Overall, potential downtime can be reduced or even avoided. 

All previous contacts at Krah AG will persist.
