5th Krah Community Meeting has been a complete success

krah invitation


From 3 to 6 June 2014 the 5. Krah Community Meeting (KCM) took place. The group of 30 participants, consisting of customers, potential parties, external technical consultants and Krah employees met in Tallinn, the capital of Estonia, in order to discuss about new projects and developments. In total 12 different nationalities were present.

Beside reports on experiences from long-term members like Krah Misr / Egypt or ForbesGroup / UK the company HENZE GmbH could present itself as new member of the Krah Community. Another thematic highlight of the conference was the introduction of software solutions for production planning and production analysis.

As final of the symposium all participants visited the quite impressive pipe production of the hosting company Krah Pipes OÜ.

The Krah Community meetings now take place since nearly 10 years, every 1-2 years at different locations, always in cooperation and assistance with a local pipe producer and have become an important and well established event in the area of large bore piping systems.

The topics, presentations and speeches will be published in the upcoming issue of „ImProfil – the magazine for large plastic pipe technology”.

Butt-Fusion of PE-GF


Since some years helical extruded pipes made of PE-GF are used in the market for pressure application.
Worldwide many projects have been realized in various diameters and for pressure applications up to 16 bar. The pipes are produced by the Krah Comtruder®-Technology, what guarantees a homogenously distribution of the chopped glass-fibers and the coupling-agent in the polyethylene-matrix. The international available standards for pipes DN/ID 400 until DN/ID 4000 are ASTM F 2720/ASTM 2720M, DIN SPEC 19674 and ISO/CD 29561 is still in process.
Mostly used in the market is the PE-GF 200 with a MRS-class 20 MPa, based on 20 % Glass Fibers, 2 % Coupling agent and 78 % polyethylene matrix of PE 100.
Joining of this kind of pipes is done either by the typical Krah-Electrofusion-Technology or by Butt-Fusion.

30 % less Energy Consumption...

 ... was not the only reason for the English Polypipe Group to purchase the Krah Compounder Concept. 

Since many years Krah is with the ComTruder® involved in the inline compounding technology.
Until today the system was used to produce and to extrude a compound based on PE/PP with glass-fiber or Calcium Carbonate as a part of the spiral pipe production machines KDR700 and DR700.

For Polypipe now Krah developed a standalone compounder to produce Polyethylene Pellets, filled with Calcium carbonate (30%). The standalone compounder, called Comtruder®, has an output of 700 kg/hr. The pellets are produced by an underwater pelletizer, what is flanged directly to the comtruder.
