Dear my 10.880 readers,

maybe you know it and practice it yourself, the daily dialog with myself especially when taking a look at today’s news. We have friends and customers in Mexico who are running Krah Lines. We are deeply concerned about the people in Mexico who are victims of the earthquake and express our heartfelt condolences to all victims and families who lost their loved ones in these destructive earthquakes.

We are also worried about our friends and people in Hokkaido, who are afraid of long distance rockets from North Korea crossing their airspace. We wish all those affected much strength for these difficult times.

I find myself wondering every day if I am doing the right things and taking the right decisions, not only as a human but also as a company. Are my products the right ones at right times on the right markets? Is my being, my current behavior and lifestyle the right one for this moment? Am I taking the right path in life or shall I do something different? What is the meaning of my life? Do I leave sustainable footprints on earth? As individual person it is very hard to face and answer this question, but as entrepreneur I can actually say that large pipe systems made out of PE or PP are needed more and more worldwide to protect the environment and create higher health standards for the people.

We develop and produce the vital lines for a continuous and fast growing civilization in our world. We help to find the most economical and technical solutions for various application areas like prevention of floodings, reduction or eliminating of soil contamination, production of food storage silos, power plants or modern waste water systems.

Our heterogeneous Krah team is ready to face the future. Our credo is it to transfer our know-how to the world in order to be able to solve local problems locally. Again and again, during the years of hard working we have faced and solved problems with all their obstacles and I’m grateful to look forward to a great future for the welfare of all people.

Have fun reading this newsletter!

Opening ceremony of new Manila plant

Krah Pipes Manila, Inc. (KPMI) has finally rolled up its plant’s doors during its inauguration ceremony last 13th May of 2017. KPMI plant is located in an 8000 square meters lot in First Cavite Industrial Estate, Dasmariñas, Cavite, Philippines which is approximately 2 hours drive from Manila.

The event was attended by various local and foreign partners, government officials and target customers with a Filipiniana themed dances and native cuisines.

Mr. Bülent Kuzkaya welcomed the guests with his opening speech which focused in the future of KPMI as it will cater the challenges that the Philippine government has been facing today, particularly in expanding drinking water distribution and containment, wastewater management, sewage treatment, flood mitigation and expansion of irrigation networks to the 7000 plus islands of the country.

Krah Pipes Manila, Inc. - First drainage project

Manila, 2017. The Krah pipes producer Krah Pipes Manila, Inc. has started its first drainage project in the Philippines.

Flooding nowadays, especially in the Philippines, has been one of the major problems of the country which threatens the life of individuals, greatly affects the livelihood of families and hinders the government’s economic growth. Up to date, a lot of control measures and mitigation techniques are being performed by different local government units but unfortunately, most of the cities and provinces still experience these fateful events. On the other hand, private developers, as major providers of housing improvement and elevating the living experience of the Filipinos, have been eager in finding a solution in preventing flooding calamities to happen especially on residential areas that are about to be developed.

Fake news about Krah technology

Social media has become a big thing today. We’re enjoying the many possibilities like communicating the latest news or product information with the world. However, the increasing media activities do have a shady side as well.

Fake news are a considerable thread today. The biggest concerns of the affected companies are the number of people who are going to believe what they read or hear and then, spread the news in minutes over the whole wide world. Is the news-spreading someone a respectful personality in the industry, the news will be true for the next level of readers. We can imagine that a lot of working hours in marketing and sales need to be invested to identify fake news and arrange necessary correction requests to the editors. As a matter of fact, fake news and unauthorized brand use is causing additional costs and damages to the affected companies. Generally behind every well-known brand like Krah is a quality assurance which is manifested in their quality and performance procedures. A high level of quality is the assurance to avoid failures in the project or causing even high costs by occurred incidents during the production. A name and brand was built up during years with a good marketing strategy and a good sustainable product reputation.

Pipe materials in comparison - Cost saving factors

For comparison of costs first of all it has to be considered, that the pipe costs are only 10-20% of the total project costs. The main part of project costs are caused by civil engineering works, disturbance of overground infrastructure and of course by soil and water management! That means the influence by using a cheap pipe system to the total project costs is very low. In fact, it should be paid more attention to the fact that for the owner the financial depreciation is responsible for around 30% of the annual costs, which means by using higher quality and reaching longer service life time the costs can be reduced significantly!

Introducing... Jochen Blickheuser

We have decided to restructure our series “ImProfil of..” and will from now on call it “Introducing....”. We have chosen our technical colleague Jochen Blickheuser to be the first one in the new layout. In the future we will also present members of our Krah Community.

Jochen has been in the company since 1986. If anyone has seen almost every department of the company – he has. He started as tool manufacturer, a few years later he moved to the construction department. When there were some restructurings he was Quality Manager for "Frank & Krah" from 1998-2006. After that he became application engineer, and now he has been in the technical sales department for almost three years.

Jochen is our “frequent flyer”. He knows the world like the back of his hand. The longest supervision journey was in Argentina in 2013/2014. He stayed there for 9 whole months. Obviously he returned home for a few days in-between to see his wife and at that time 6-year-old daughter. Travelling is his passion and he is always happy to visit our customers or partners to discuss new business or to supervise them with any technical questions. His speciality is our E-Fusion-Technology (for further information please visit www.krah-pipes.de).

Quality Control for non pressure applications

To provide a high quality pipe system, all Krah pipes have to pass the following minimum quality control requirements. In case of inside pressure applications, additional tests can be applied.

Additional to the own, in-house quality control a third-party, random inspection is recommended, to ensure a high quality product – the Krah Pipe System. The third-party quality control should take place twice a year. The company´s internal Quality Assurance department should provide a form for the checking. All samples checked shall be considered representative for the whole production. Raw material tests should be carried out before adding the product to the production cycle. Undamaged / non affected samples can be sold afterwards. Those tests made in Krah-Production Plants are exceeding the requirements of the international standards like DIN16961, ASTM F894, etc.

EL-Lene H112PC - Superior Strength Polyethylene Black Compound for Pressure Pipes by SCG

Since ancient Roman aqueducts, water management has been continuously developed to become pipeline system and plastic appeared as the rising star material. With benefits of lightweight and flexibility, plastic was first used for pipes in the early 1950s, with continuous development of higher strength all along since then. Starting with PE63, the first generation of HDPE pipe material, followed by PE80 with an improvement of pressure resistance, the plastic pipe industry is now in the era of PE100, the third generation of HDPE pipe that was significantly developed in its key properties. In the present, PE100 is used to convey various types of flowing substances including water, gas (fluids), and slurries.

In 2014, SCG Chemical Co, Ltd. has successfully developed EL-Lene H112PC, an innovation with higher pressure with an MRS of 11.2 MPa. Our own developed polymerization process and special catalyst were selected to produce this advanced material, resulting in PE112 with no knee that perform beyond current conventional PE100.

Bending and curving of profiled Krah pipes

The high flexibility is already very known for Krah-Pipes, and a basic reference for the bending is given by R=50 x DN/ID for long term and even R=25 x DN/ID for short term.

So technically these two cases have to be diveded, in long and short term examination. The long term is to reduce fittings (bends) and the shirt term aspect is during the installation e.G. using the S-sinking method in water applicaitons, relining. What is a easy way to make a detailed calculation, to be sure that the pipe will not fail. How to calculate the minimum bending radius for a Krah-Pipe with profiled wall structure, in helical style?

Water hammer and how PE pipes react

For designing a pressure pipeline all pressure load phases must be considered and in reference to the loading time be evaluated. Besides the test-pressure, the maximum operation pressure (MOP) and also the water hammer effect have to be considered and implemented in the static design! This procedure is valid for all pressure pipe materials and systems, but flexible pipe materials provide some advantages.

What is a water hammer?

A water hammer is a pressure surge or wave caused when a fluid in motion is forced to stop or change direction suddenly. A water hammer commonly occurs when a valve closes suddenly at the end of a pipeline system, and a pressure wave propagates in the pipe. This pressure wave can cause major problems, from noise and vibration to pipe collapse. But it is possible to reduce the effects of the water hammer pulses with bypasses, expansion tanks, surge tanks, blowoff valves and other features. Rough calculations can be made e.g. by using the Zhukovsky equation, also known as Joukowsky equation.
