(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.
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:
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.
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.
The following abstract provides a brief description of the Al Ghubrah Project with information regarding installation of Large Diameter Marine Intake and Outfall Pipelines, especially regarding the typical work phases: Survey, Design and Construction.
The Al Ghubrah Desalination Project is formed under the Independent Water Project Scheme in Muscat, Sultanate of Oman. The project is sponsored by Muscat City Desalination Company SAOC (MCDC); contracted to the joint venture M/s International Water Treatment Co LLC (formed by WABAG, CADAGUA, & GALFAR). The project is located approximately 20 Kms on the eastern side of Muscat city. The Intake and Outfall Pipelines are produced locally as solid wall Krah-Pipes at United Gulf Pipe Manufacturing Co LLC based in Rusyal Industrial Estate, Muscat, Sultanate of Oman.

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.
