Technical data on our pipe systems

Here you will find detailed technical information on our stainless steel pipes and fittings. All data is based on current standards such as DIN, EN and ASTM and gives you a transparent overview of materials, chemical analyses and dimensional tolerances. These technical principles form the basis for safe, reproducible and durable applications in a wide range of industries.

In addition to material analyses according to DIN 17440 you will also find information on tolerances according to EN ISO 1127, ASTM A 312 and ASTM A 269. These standards regulate the permissible deviations in wall thickness, outer diameter and straightness of the pipes. This means you can rely on consistently high dimensional accuracy and quality, a decisive factor in automated welding processes or precise pipe installations.

In addition, the technical tables provide information on the chemical composition of our materials, their physical properties and the relevant production specifications. This provides you with a comprehensive basis for planning, selecting and processing our pipe systems in your area of application.
