Why profiled pipes?

Since the people have begun to found towns and cities, transport facilities for water and sewage water have been needed. Pipes were constructed and gained more and more in importance.

With the growing demand and modified requirements again and again the people looked for alternative production methods and materials for the pipes.

With the proceeding industrialisation also plastics came into question and thus, decades ago, the people started to produce pipes with all different kinds of plastic materials and made use of the advantages of this kind of material.

The HEBEISH AG has benefited from the properties and advantages of the plastics for the pipe production (especially polyethylene and polypropylene) and enhanced existing production procedures. The results of these developments are the profile types VW, PR, SP, ST and SQ.

The aim was to be in the position to offer the customers an ideal solution of a total pipe system, so that they are able to serve the requirements of the projects with pipes and fittings from DN 300 to DN 4000.

The pratical experience showed us, that it is necessary to be in the position to offer pipes, which are applicable for all kinds of conditions.

Therefore different kinds of pipe wall profiles have been developed, which are combinable with nearly all kinds of diameters. Further it is important to produce pipes as inexpensive as possible. For this purpose changeover times have to be reduced in order to have an advantage to the pipe producers which use other pipe production procedures.

During the whole development stage it is very important for us to meet the demands of the existing norms. Not only because of the high flexibility of the HEBEISH piping system we have succeeded to meet the German standards DIN 16961 or DIN 8075 as well as the standards of other countries like the European norm prEN 13476, the Brasilian norm NBR 7373, the Japanese Norm JIS K 6780 and the US Norm ASTM F894

Another important point is the design of the pipe wall. In former times very big wallthicknesses for pipes had to be used in order to maintain loads which influence the pipe.

The results were heavy and very expensive pipes although wallthicknesses stipulated in the norms would be sufficient for the actual application of the pipe.

In order to solve this problem the profile pipes have been developed. A profile is added to the minimum required basic wall.

The profile is connected to this wall. This profile which is calculated by a special software produces a significantly higher moment of inertia and thus the loads can be carried. For comparison, a solid wall pipe
of the same material with the respective moment of inertia would weight three times more.
