Estonian mobile bomb shelter can withstand NATO calibre shelling

All that emerges from the ground is a yellow tube, but it is no ordinary plastic pipe. It can withstand NATOcalibre shelling and hold up to 12 people in temperatures ranging from -50 ˚C to +80˚C.

Dubbed the Sub Safe U1, the Estonian-built bomb shelter is made of plastic to render it both portable and waterproof. A fact which Terramil, the company that manufactures it, says makes it unique in the world and it can be assembled in a rush.

The shelter is about six meters long and weighs around two tons. Terramil representatives note that it can be installed using a simple digger. The company says if it is placed up to 50 metres underground it could even withstand a nuclear attack, although that has yet to be proved.

The unit has been tested by the University of Tartu as well as by US NATO forces currently on a training mission to the country.

“We have tested it now against a range of different weapons and as you can see there is no damage here,” noted Kirtsi. “We have measuring equipment inside here to measure the pressure, vibration, sound levels, everything like this that can be dangerous for people inside. And again we have had no damage to the shelter so far.”

The units can even be connected together to create an underground city, but the room without a view comes with a price tag of 18,000 euros for a simple 12 bunk model.

Saudi Arabia, Pakistan, India and Egypt have already expressed interest in buying the modules.

 

(DE) Rohrleitungsbau in riesigen Dimensionen zur Aufbereitung von Flusswasser in Argentinien

 "bbr, November 2014 (German)

Um der unzulänglichen Trinkwasserversorgung vor allem im Ballungsraum Buenos Aires entgegenzuwirken, hat die argentinische Regierung das Großprojekt „Planta Potabilizadora Juan Manuel de Rosas“ ins Leben gerufen. Vorgesehen ist, das Wasser zweier Flüsse in ein Wasseraufbereitungswerk im Norden der Stadt zu befördern. Die Anlage soll durch die neuen Anschlüsse frisches Trinkwasser für zwei Millionen Einwohner zur Verfügung stellen können. Beschrieben wird der Projektabschnitt des Zulaufflusses Paranà de las Palmas – die Leitungen wurden in der außergewöhnlichen Rohrdimension DN/ID 3600 ausgeführt.

The New KR800 – next generation!

The last major development of our production line was four years ago, when we changed from KR700 to KR750. This year (2014) after a long time of small improvements and complete new developments, we have finally completed our new generation of our KR-serie – the "KR800". The first machine of this new line is shipped to our customer in Poland to conquer the market in East Europe. We are convinced this machine will be only the beginning of a new successful generation of production lines for spiral pipes.

We are happy, because we are „The Best“

(proved in China)

 

It is very normal and common, that German machines are being copied, especially in the area of plastic processing machines. Everybody is upset, but only few companies take legal measurements against it.

Also our machines are more or less successfully counterfied and copied by approximately 5 Chinese companies. The great thing about it is, that they do not only copy the hard- and software but also our name.

Rules and Standards for large diameter plastic pipes

In the following abstract an overview is given about the basic rules and standards for large diameter plastic pipes. The main focus made from German/European view on the thermoplastic pipe materials Polyethylene and Polypropylene.

In the list the standards are marked according their relation to:

  • General
  • Polyethylene / Polypropylene
  • Raw material properties
  • Pipes
  • Fittings, Assemblies
  • Manholes
  • Jointing

It is of prime importance for the industry to be geared to the established standards.
Without adequate standards there would be no orientation on the free market. This concerns designer, planer, fabricators, operator, testing institutes as well as the manufacturers and his quality management. Of course this does apply also for large diameter thermoplastic pipes. Especially, because thermoplastic materials are with around 70 years of experience still a young material group, which results in immense drive and innovation.
