During final acceptance testing, some very outstanding results were achieved: in particular, it was possible to quench a pipe of steel grade 4140 of 50 mm wall thickness, reaching 90% of martensite without generating any cracks in the pipe, as the ultrasonic test confirmed. Such result is enabled by the precision and performance of the control system of SMS group quenching devices. According to TMK-ARTROM, currently no other pipe producer is able to reach these results with a water based quench. “SMS group has confirmed its longstanding experience and reliability as a partner able to successfully deal with technological challenges like this commissioning at TMK-ARTROM,” states Cristian Drinciu, COO of TMK-ARTROM.
