control of pipeline partsCustomer: a company that produces stainless steel piping parts – flanges, elbows, fasteners, transitions, plugs, tees, and other products of this kind.

Description of the goals and the current way to achieve them: perform test on produced parts, the medium weight of around 2 kg (2,2 lb). The client is running selective tests with a stationary hardness tester in a friendly laboratory right now. He is going to recalculate readings obtained with the UCI hardness tester.

Demonstration: after considering the task given by the customer, our professionals took the TKM-359CE Leeb hardness tester and the UCI hardness tester TKM-459CE ("Universal" kit) with them, as both instruments' settings include scales designated to measure stainless steel. There is no need to make any additional adjustments.

 

control of pipeline parts_1We ran the tests in the client's office premisses on the following samples:

 

  • stainless steel flange 12Х18Н10Т with a diameter equal to 215 mm and the weight equivalent to 4,7 kg (8,8 lb)
  • stainless steel flange 12Х18Н10Т with a diameter equal to 160 mm and the weight equivalent to 2,2 kg (4,4 lb)
  • stainless steel flange 12Х18Н10Т with a diameter equal to 139,7 mm

The expected hardness rate of all items checked was 235 HB, the resulting data of the demonstration tests showed 229 HB.

Conclusion: the customer was contented with the experiment results and has chosen our TKM-359CE Leeb hardness tester.
