Kappa LA with Dead Weight

This Kappa LA lever arm testing machine maintains constant load application via the gravity force of the dead weights and the patented lever arm.

  • Wear-free flexible joints provide high-quality lever arm mounting and ensure Class 1 measurement accuracy in a measurement range from 1 to 100% of nominal force as per ISO 7500-2.
  • No friction, no wear and constant force application.
  • Maximum precision, maximum reliability and long service life
  • Controlled lead screw drive maintains the lever-arm in a horizontal position during the test
  • Axiality compensating links in the load axis

Kappa LA with Pretensioned Spring

This Kappa LA lever arm testing machine maintains constant load application via a pretensioned spring and the patented lever arm mounting.

  • Wear-free flexible joints provide high-quality lever arm mounting and ensure Class 1 measurement accuracy in a measurement range from 1–100% of nominal force as per ISO 7500-2, while eliminating knife-edge problems during the entire service life of the machine.
  • No friction, no wear, and constant force application
  • Maximum precision, maximum reliability and a long service life
  • Precise load and strain control
  • Controlled lead screw drive maintains the lever arm in a horizontal position during the test
  • Axiality compensating links in the load axis

Vallourec equips research center with 60 Zwick creep testing machines

The Vallourec group is the leading manufacturer of seamless hot-rolled steel tubes, with manufacturing plants in Europe, Brazil, the USA and China. The new Vallourec research center in Riesa (Germany) employs experts in the fields of metallurgy, materials testing, steam oxidation, and product simulation. The experts have access to state-of-the-art technical equipment, comprising amongst others a scanning electron microscope and, at present, 26 Messphysik Kappa 50 LA creep testing machines. In mid-2013 the laboratory has been extended by further 34 additional lever-arm creep testing machines.
