Line pipes and thus induction-bent pipes are frequently exposed to extreme conditions both during pipe-laying and pipeline operation. Despite this, they have to maintain their functional integrity in continuous operation over decades. To ensure uniform high quality of our bends, we carry out a range of nondestructive and destructive tests. The results are entered in detailed test reports as part of our documentation. Our customers and partners can of course also witness the tests at our plant.
The following nondestructive tests are carried out as standard by duly qualified operators directly at our pipe bending plant:
For destructive testing, specimens taken from qualification bends or selected pipe bend ends are sent to the near-by testing center of Salzgitter Mannesmann Grobblech, which is accredited to DIN EN ISO/IEC 17025:2005 and ranks among the most efficient testing centers worldwide.
The mechanical-technological tests carried out there include:
Special destructive tests are carried out in direct cooperation with the Salzgitter Mannesmann Research Institute in Duisburg:
