Polyethylene pipes are successful worldwide due to the superior performance (Flexibility, light weight, lifetime, tighten joint) for water and sewerage supply. However according to our ISO standard concerned Polyethylene pipes we have to use solid wall pipe with too thick against for internal pressure. The major job challenge involved finding new polyethylene solution with best high modulus and flexibility such as superior performance of polyethylene for world customers. In achieving this, polyethylene resin with glass fiber by spiral cross winding method take us new.
Our technical team should be considered a better option (characteristics of basic) not only those tests but also it was extra performance with proof of some analysis in Japan.
PE pipes have been successfully used for water distribution pipelines around world for many years. Those pipes are generally made with solid walls because of strong deflection of the pipe during terms of service. This is necessary to need over hundred mm thickness in case high internal pressure especially for large diameter pipe. This paper provides technical characteristics and discusses solid wall pipe applications with Polyethylene and Glass fiber. It combined high E-modulus and many benefits of polyethylene. HIPPA as High stiffness Polyethylene Pipes association established 1987 are operated by DAINIPPON PLASTICS, NIPPON HAWER, TORIIKASEI,
PRIME POLYMER and MITSUI CHEMICALS INDUSTRIAL PRODUCTS in Japan. We should know what we are those basically characteristics concerned Plastic piping systems made from glass fiber reinforced polyethylene (PE-GF) for water supply and for drainage and sewerage.

Water distribution and water usage have been in the focus of the authorities and the civil society of Argentina for many years. From an infrastructural point of view this issue raises complex problems, which have emerged through several changes between privatization and communization over several decades. The incomplete supply of numerous households with fresh drinking water such as safe sewage water connections are obvious results of these which need to be faced and solved. To address these shortcomings, especially in the metropolitan area of Buenos Aires, the Argentine government has launched the major project: Planta Potabilizadora Juan Manuel de Rosas.
Within this major project, river water is taken out from two rivers and transported into the water treatment plant in the north of Buenos Aires. The treated water will mainly benefit the districts of Tigre, San Fernando, San Isidro, Vicente López and San Martín. The water treatment plant will provide fresh drinking water for two million residents. The river’s name from which the project section we have been working in took its resources is Parana de las Palmas. It is an inlet flow of the great river Rio de la Plata close to Buenos Aires.
Krah Pipes OÜ was approached by people from Von Krahl theatre in Tallinn (http://www.vonkrahl.ee/). They had seen our pipes & products in various strange applications and asked whether we can help them with s futuristic setup for a play called „The Curse of Solaris“. In cooperation with the theater’s people necessary „products“ were chosen & produced. Among just pipe segments also some futuristic chairs and even high heels were produced. The play was performed during the month of June and received high marks from the critics. I had a chance to visit the premier of the play and I have to admit – it just was very good. Really hard to put it into the words as it did not resemble anything I had seen so far in my life.
During the installation of the largest polyethylene pipe with a solid wall and an integrated electro fusion joint, in the area of Buenos Aires, at the river Rio de la Plata, in Argentina, our team took advantage of the unique possibility to take some more photos for the calendar 2015.
This project site was an intake line with a size of DN/ID3600 mm, with a solid wall thickness of 220 mm, jointed by the integrated Krah-Electro fusion joint. The video will prove that the pipe is really so large and that the pictures later in the calendar are not made with photoshop J. A complete report of this project will be published very soon on this homepage and also in our upcoming new Improfile issue.
The new calendars will be shipped in December 2014 – so you still have some time.
A total of £2,336.31 could be raised, which will be donated to Prostate Cancer UK. Prostate Cancer UK is the leading UK charity for men with prostate cancer and prostate problems, with your money assisting those affected and allowing vital research to take place.
Polypipe’s Commercial Manager Steve Smith and his co-driver Keyline’s Steve Dewing drove the Mini Convertible ‘Batmobile’ from England to Hamburg, camping and completing tasks on the way in aid of the cause driving through France, Belgium, Luxembourg, Germany, Holland and back into France before returning to the UK.
As well as Polypipe participating in the Rally, Directors Glen Sabin, Steve Kite, Andy Cullum and John Moss cycled 300km from Berlin to Hamburg in support of the cause.
Overall the Rally and cycle ride proved a great success.
