Merry Christmas!

Picture

Here, in the region of the Westerwald, in the middle of Germany, the days become shorter, the temperatures drop and the nature seems to be in winter sleep. If we are lucky we will even have a “white Christmas” this year after quite a long time. People are putting on warm clothes and reduce their activities.

Christmas is just around the corner, the most important holiday of the year for us. These days signify a time of joy and quality with family and friends for all of us, but also tranquility and contemplation.

Also our company will be put into “sleep mode” for a couple of days. Most of the companies, close their business year on 31 December just as the calender year will end.

Last turnovers will be accounted, last emails and letters of the year will be sent, among those a lot of Christmas cards as well as our last issue of the Improfil Newsletter for 2017.

We can proudly say that we have achieved and developed a lot in 2017. Also this issue contains a lot of technically interesting reports.

We are looking forward to 2018, full of new products, ideas and developments. Wishing you all, wherever you might live on this beautiful planet a peaceful and contemplative Christmas season and a healthy start into the new year of 2018!

All the best!

Flooding prevention using the example of the City and metropolitan area of Manila

Manila, capital of the Philippines, has around 1,8 Mio inhabitants and is situated in the agglomeration “Metro Manila” with a total of 12,9 Mio citizens. The immense population pressure since the middle of the 20th century caused an uncontrolled expansion of the city Manila and the surrounding conurbation.

The planning and construction of the installations of sewage discharge and treatment systems as well as storm water distribution could not keep up with this growth. Thus, drainage systems yes do exist, but do not meet in any way to the objectives of integral urban drainage systems. Especially the inadequate hydraulic dimensioning of the distribution pipelines, which are mostly done in the diameter of DN/ID 900 mm, regularly lead to overload flooding in a lot of districts of Manila.

The hydraulic failure of the systems is even intensified by the need of relining and repair, wrongly constructed manholes, false installation of the pipelines as well as root infiltration and blockings. On basis of the applied regulations of the German association for water management, waste water and waste (Deutsche Vereinigung für Wasserwirtschaft, Abwasser und Abfall e. V. (DWA)) and DIN norms possibilities for a safe discharge of waste water as well as the protection against flooding shall be presented.The current situation in Manila is difficult: Due to the demographic development of the last ...

Ukrainian pipe market - Renovation of infrastructure

Leaders of Ukrainian market of construction and installation of pipelines are ready to work on international level

On November 2016 in Lviv, Ukraine, there was a solemn ceremony of opening a new tramline connecting residential district Sykhiv with central part of the city. Only few people attending the ceremony knew that it was preceded by another event, not less important for the city’s life. It was replacement of old 520-meters underground non-pressure sewage collector located directly under the future tramline track. Replacement of the old sewage collector on the Stusa Street was the biggest infrastructural project implemented in the period of Ukraine’s independence over last 26 years.

Worn-out condition of the old collector could have caused damage of the road bed above it. That’s why Lviv City Council and Lvivvodocanal organization decided to urgently replace the old collector with a new one. This difficult task was assigned to INSTALPLAST HV company and its subdivision INSTALBUD which performs works on construction and installation of internal and external pipelines, natural gas pipelines and sewage networks. Replacement works were done according to the project designed by German specialists. The works started in June 2015 and ...

Extensive earthquake dynamic fitness test of the complete Krah Pipe system

Preface:
One of the most used arguments for plastic pipe systems is the flexibility and durability. If a question appears about earthquake fitness, the plastic pipe industry normally replies by showing damage-statistics. And indeed, the statistic results are very convincing, especia

lly with damage statistics of rigid pipe systems. In the last editions of our IMPROFIL magazine we published many reports regarding earthquakes (mainly from our friends in Japan)- but a practical orientated dynamic test of a complete plastic pipe system with all aspects of different jointing methods, fittings and constructions has never been done before.

Thanks to the initiative of Krah Pipes Estonia, the well-known Russian JSC Research Center of Construction in Moscow has performed an extensive test program to investigate the earthquake fitness of the full Krah Pipe System with seismic intensity of 7-9 magnitudes. For the complete technical report please contact the management of Krah Pipes Germany directly (email: krah@krah-pipes.de). 
Below please find the summarized technical report with the original title:

Flexibility or flattening test? What does it mean and why should a pipe fulfil the requirements?

What does it means and why should a pipe fulfil the requirements?

Today the requirements for a sustainable pipe system have changed, not always the cheapest solution is the best for a country. More and more designers and engineers dare to search for the technically best product for a project, at very reasonable costs. Also the cost aspect changed from single costs to the „lifetime cost“– from cradle to crave, including all.

So, which support for a designer or a quality control department does the so called flexibility test or flattening test mean? How is the test-procedure and how should the result be valued? In several international and national standards like EN13476, DIN16961, ISO 21138 or the ASTM F-894 a link to these tests is given – but why?

Basically the test will check how flexible a pipe can be, without having any irreversible damages on the pipe. This pipe property will give safety to the designers against overloading of the pipe or ground-movements occurred by earthquakes or unexpected soil settlement.

The standards for the test: The flexibility test is ruled in ISO 13968 and the flattening test is ruled in ASTM F894 8.6.

What is the difference ?

First days of KR800-MAX - The final test of the latest pipe production line before shipping

This time the newest KR800-MAX is tested according to a very specific testing procedure to guarantee a quick and error free installation at the customer´s site. Several potential new customers from all over the world took the unique opportunity to enjoy the high performance of Krah-Pipe Production machines and also to take a company tour – so they can pay a visit in the RnD Department, Software developing department (WIN-KDR, MICKEY, PONTIS and all other APPs are developed here), tool making, construction, installation and also to the very impressive „mandrel“-production, where black-smiths are working hard with steel to produce giant mandrels up to DN/ID 5000 mm.

The machine presented will be shipped and installed for a customer in the Middle East where it will produce pipes successfully for a lot of pending huge projects.

This test procedure is the same for every production line, before being packed and leaving our facility. The test are mainly done with the extrusion line, because many other parts are already shipped in partial shipments before. It is the first time in the machine life a pipe will be produced. The heart of the extrusion line is a Kraus-Maffei single screw extruder 125x36D. This extruder is the best choice for this kind of production – low RPM (revolutions per minute) and a high output with ...

Krah Pipes on artistic - Krah pipes producer Polypipe attends FIAC in Paris

For the 44th Foire Internationale d’Art Contemporain, (International Art Fair, FIAC) in Paris the American artist Oscar Tuazon created an installation made of water treatment pipes by our partner Polypipe, two metres in diameter, and presented a series of sculptures on the Parisian Place Vendôme.

The sculptures were exhibited during the whole month of October, drawing the attention of many pedestrians and visitors from around the world. Many visitors were highly impressed by the size of the pipes: a tall man could easily walk through them without any problems. But it was not just the height that was so impressive. Many people actually thought about the importance of pipes and water in our world. Mr. Tuazon addressed the problem of water resources very clearly and explained the meaning of the sculpture to those interested.

On this point, he says “Our world is water. So we produced an homage to water in form of a sculpture. A pipe, a hole, in which water flows through below ground, a passage from one way to another. Water is an open room below ground. We need to go there, move in the canalisation and live there.” On each side of the war memorial, which stands on the “Place Vendôme” are four sections of fabricated pipe assemblies. Inside each of ...

The new Krah calendar for 2018- Every year a big event …

For the first time in the Krah calendar history we were able to shoot the whole calendar in one day.

On the 15th of October at the Frank GmbH facility in Wölfersheim, Germany, the day started very early – the first pictures were taken at 7a.m., the last at 8 p.m. We had great support from the General Managers at Frank, Ms. Heike Frank and Mr. Mark.

Instead of doing the shoot in several companies with different photographers we placed the whole thing into the hands of a professional: Petra Kladivova. Owning a model agency in Czech Republic, she organized the models and the photographer. Having already worked with us for our previous calendar, she knows how to present our pipes and products in the best possible way. The Frank GmbH owns 3 Krah production lines and a large fabrication plant for special components produced out of Krah pipes. The photographer was Pavol Bigos from Pinarto Studio. We used 5 different models to fill 12 months plus a beautiful cover photo. All models came from ...
