PE pressure pipes CE marking – Based on Construction Products Regulation, which came into force 1 July 2013 all construction products in the market of the European Economic Area and covered by a harmonized European standard must be CE marked. CE mark is not allowed when the construction products are produced by not harmonized standard. Because standard EN12201 is not harmonized in EU, polyethylene pipes produced in HAKA Plast do not have the CE marking. When the harmonized standards are published also in EU, HAKA Plast will insure that our products will be immediately CE marked.

PE80 is a high density PE material. The pressure pipe made of PE80 raw material is flexible, shiny, strong and resistant to most chemicals. Pressure pipes made of PE80 raw materials are mainly used in geothermal circuits and real estate construction for house and apartment connections. Outside the building, pressure pipes made of PE80 raw materials are installed using the open trench method.

PE100 is a high density PE material. The pipe made of PE100 raw materials is shiny, strong, and most chemicals resistant. The main use of pressure pipes made of PE100 raw materials is the construction of external pipelines and mains. Pressure pipes made of PE100 raw material are installed using the open trench method.

PE100-RC is a high-density PE raw material where RC (resistant to crack) shows resistance to cracking and crack propagation. Pressure pipes made of this raw material are intended for use in more complex conditions and are particularly suitable for trenchless installation methods (no dig). Pressure pipes made of PE100-RC raw materials are shiny, strong and resistant to most chemicals. The main application of pressure pipes made of PE100-RC raw materials is the construction of external pipelines and mains.

PP or polypropylene is a high density thermoplastic. Its properties are similar to polyethylene (PE), but it is slightly stiffer and more heat resistant. It is a mechanically resistant material and has a high chemical resistance. HAKA Plast uses PP raw material only in the production of type 3 pipe, where the PP layer is added on  PE pipe, to protect the pipe when installed by trenchless methods (no dig).

PEHD REG

PEHD REG is a secondary raw material regranulated from the primary raw material (PE80, PE100, PE100-RC). After regranulation, the properties of the primary raw material mainly decrease in density, which means that pressure pipes cannot be made from secondary raw materials. HAKA Plast manufactures only non-pressure pipes, such as telescopic and cable protection pipes, from secondary raw material.
