Pressure rating tables
Reliable pressure values are essential for accurately assessing the load-bearing capacity of stainless steel pipes. Our pressure tables provide you with a precise basis for calculating the calculated operating pressure in accordance with DIN 2413 at 20 °C. They enable a quick assessment of the pressure resistance for seamless and welded stainless steel pipes made of material 1.4435 / AISI 316L.
The specified values are based on current standards and take into account both metric and imperial pipe dimensions. This means that our pipe systems can be easily integrated into international plant standards. You benefit from a high level of planning reliability, whether in plant construction, process engineering or sensitive media lines.
All pressure data from our pressure tables have been carefully compiled on the basis of technical calculations and serve as a guide for the design of your systems.
This creates the ideal conditions for a safe, efficient and durable installation.
The system operator is responsible for the design of the operating pressures. Laffert GmbH accepts no liability for the values given to the best of its knowledge
