After years of research, today STAR is the first and only manufacturer able to produce DVGW-certified seamless bends with r = 1.5 x d, keeping the minimum wall thickness required in compliance with DIN EN 12201-3 and DIN EN 1555-3, thus ensuring optimal conditions even at highest strain.
What is behind DIN EN 12201-3 and DIN EN 1555-3?
The standards DIN EN 12201-3 and DIN EN 1555-3 define quality standards of PE pipeline systems for the gas and water distribution as well as for irrigation and waste water pipelines.
Any dimension as well as tolerances and material properties are specified by these standards. The wall thickness of seamless bends is part of the stipulated dimensions. The ending number “3” of the standards indicate the sections that not only define the pipes but also the requirements for the finished fittings. DIN EN 12201 is the standard for water distribution, irrigation and waste water pressure pipelines, while DIN EN 1555 is the standard for PE pipeline systems for the gas distribution. Seamless bends that are conform with both standards can be used for either gas and water. This is the case with the norm-compliant seamless bends by STAR.
While the bends comply with the standards, the seamless bend is furthermore certified by the DVGW. A product with the DVGW hallmark gives you the assurance that it is state-of-the-art and conform with established regulations.
The so-far worldwide only DVGW-certified seamless bend produced by STAR stands out prominently from other seamless bends and distinguishes itself verifiably by a considerably long lifetime and high reliability.
By guaranteeing the minimum wall thickness, standard-compliant DVGW-certified seamless bends by STAR provide highest safety and enable pipeline construction according to standard, meeting highest demands.
