Thermatool High Power High Frequency HCT Welder Similar Installation Click image to enlarge

A Russian steel welded pipes manufacturer has purchased Thermatool high power, high frequency welders and 12 post weld heat treatment seam annealers to support its manufacturing operation.

Vyska Steel Works, a unit of OMK, will be commissioning casing line pipe and tubing mills that will produce seven and ten inch pipe using induction and contact welding with dual capability.

The 7 in. mill consists of a 1000 kW HAZControl Technology HF Welder and 2000 kW of Seam Annealing induction power employing Seam Tracking and the latest in Advanced Yield output software. Both mills will also employ Thermatool 250 kW End Weld Annealers. The 10 in. mill is equipped with Thermatool’s High Power/High Frequency 1400 kW HAZControl Welder (with a dual setup for welding in either contact or induction mode), along with 3200 kW of Post Weld Heat Treatment.

Thermatool's HAZControl technology will allow Vyska to create weld characteristics through recipe creation using Power, Frequency, Vee Length and Mill Speed for specification requirements for consistent, repeatable, efficient production runs. Developing databases of production parameters for a variety of steel chemistries and final specifications helps the producer to ensure maximum mill output while reducing scrap percentages.
