This issue of "Improfil"

Dear readers,

Every three years the most important event we take part in is the K-show in Düsseldorf, Germany. The No. 1 trade fair for plastics and rubber worldwide. This year we are pleased to present you our latest developments like the software “PONTIS”, an IR-Camera for quality control, new profiles, higher outputs, customized machines ( tank production) and much more. Additionally, we will inform you about the newest pipe applications, like large outfall pipelines (see picture of Isidro Sierra and me visiting an outfall pipeline in Peru).

I am very excited and looking forward to this approaching event as nearly all our existing and many potential new customers will come. Certainly we will offer daily fresh food and nice drinks to all our friends who are very welcome to have a rest at our booth. Within the scope of the K show we will arrange an unforgettable party night to welcome our Krah-Community members. The motto of the special event: – “Undead rising”. So be curious about it!

Here we will also present the first photographs of our collection “Girls and Big Pipe Technology” a calendar for the year 2014. Again: Be curious about it! ?

I hope to meet you on the show...

Yours

Alexander Krah




Method for Installation of PEHD Manholes
A technical report with 29 self-explanatory Figures


1. HDPE Manhole & Chamber Design

PEHD Manhole and Chamber design stipulates various manufacturing configurations dependent upon actual site conditions. A number of factors including water table height, depth of cover and backfilling materials have significant impact on base configurations.

Picture

Where PEHD Manholes and chambers will be installed in areas with high ground water levels, a double bottom construction is recommended, which has to be filled with liquid concrete at the job site. In the case of the double bottom type there are two openings in the upper bottom one is for the filling of the liquid concrete and one is for the venting during the filling process. These openings need to be closed after filling and hardening of the concrete with covers. When installing the manholes up to 1200 mm diameter in ground water, for lift-retention reasons, a backfilling width of at least 50 cm is to be maintained outside and a concrete filling of the benching may be necessary.

Forbes opened new Kelso Krah facility

Picture

Forbes Technologies Ltd, UK’s leading manufacturer of tanks, scrubbers & other chemical plant in thermoplastics & glass fibre composites opened the latest automated KRAH production plant for large capacity tanks in thermoplastics in August 2013.

On 6th August Michael Moore MP, the Secretary of State for Scotland opened the new production facility at Forbes Technologies Ltd in Kelso in The Scottish Borders. The facility enable the automated production of tanks & towers up to 4 meters diameter and up to 100,000 liters in thermoplastics. It is sited on 1.7 acre site alongside their already large production facility & incorporates lifting capacity for the production process of 32 tons


Forbes Technologies have already taken a number of substantial orders for their new helix spirally wound thermoplastic tanks, known as their HVT range.

10 Questions for...

Don't be a "ME TOO" - BE UNIQUE!

During the crisis in Europe a lot of pipe producers have been facing big problems in marketing the standard pipes, because there is a huge surplus on the markets. Because of the cutthroat-competition the pipe producers are under high pressure to reduce their costs and to find new markets and applications.

The consequence is that some of the pipe producers are using more and more low-cost and recycled material to reduce their costs. This critically affects the quality of plastic pipe systems and their reputation in general. A lot of companies have to escape from their home markets or are forced to shut down their production completely.

All producers of standard commodities are facing this situation and low market prices. Only companies with the individual solutions are still able to survive and to receive orders by supplying high quality products. So, it is not anymore the best solution to be a “me2”. Today a pipe producer should have his individual USP (unique selling points) and not only marketing-USPs.

We, the Krah AG, are helping customers to design their own products, like outfall pipelines, slurry pipes for mining, large storage tank with integrated leakage control, ventilation pipe system, pipes with fillers just to name a few. At the same time we are prepared to grant our customers some kind of exclusivity for their region and the product.




Krah Pipes go crazy




Segmented fittings fabricated from large diameter polyethylene pressure pipes

Segmented Fittings are state of the art for large diameter polyethylene pressure pipe systems. The maximum injection molded bends and T-pieces are until OD 500 available, injection molded stub-ends until OD 630. In larger diameters segmented fittings are the first choice. To guarantee the required homogenity, stability and strength it is most important to use a high quality pipe and a proper welding-technology.

Segmented fittings are used for gravity and for pressure application as well. Direct extruded and helical extruded pipes can be used, but especially the helical extruded pipes are preferred by many manufacturers, because the wall thickness can be increased easily. An increased wall-thickness is necessary to compensate weakening-factors for welding and shape of the segmented fitting.

Pontis - we bridge the office and the machine

Picture

Pontis is a software package to monitor your KRAH machine from almost everywhere, from the view of a production manager or the general manager. It is not showing boring data or screen shots of the control panel but Pontis is nearly sending real-time production data, which are necessary to run a plant. Reports which have been previously made manually are now being produced without any manpower and nearly in real-time. The information can be received everywhere where internet access is available and without any special software but your standard internet browser on your computer, tablet or even your smartphone will provide you with the complete information.


You will know directly the downtime and the reason why the machine is not running (not making pipes and money). Also the numbers of produced pipes and the output in kg/hr will be shown.

World largest drum, made by Krah

On the 10th of August 2013 the beautiful town of Tõrva (Estonia) hosted it's yearly spell casting festival Tõrva Loits. This is the sixth time Tõrva Loits is held, bringing to the audience great performances, leading musicians and exciting spectacle in a lovely natural setting.

The highlight of the evening was the unrivalled open-air spectacle "The Greatest Hits of Kalevipoeg". Directed by Mart Koldist, choreographer Märt Agu. Featuring popular bands and singers such as Jaan Tätte, Tanel Padar & The Sun, Päär Pärenson, 300 dancers, 200 choir singers and world's biggest drums the collective performed best bits of the Estonian national epic "Kalevipoeg". The world's biggest drums were made specially for the festival a few years ago from Krah pipes by our partner Krah Pipes Estonia and have been used for several other events since.

This is Kalli

Picture

This is Kalli, Kalli is an engineer at the Krah AG. He is already retired since a few years, but now he came back with his mission to explain Krah technology in a very simple way to nearly everybody. To present and underline his explanations he is using video, so that also everyone else can use his videos through www.youtube.com (you can find it on the channel of Krah AG, you just have to subscribe the channel and you will be always up to date for any new videos) in the internet or from the Krah AG home page (www.krah.net).

His idea is to make the video in several languages. The first videos, that will explain the Krah Pipe System and the Production Process is available in English and German. Other languages will follow by the end of this year.


Kalli will also be very happy if schools, universities and other authorities will use his videos to bring the Krah technology closer to the people.
