Thermatool provides pipe production equipment to Vyska Steel Works

This Thermatool HCT welder is similar to the one installed in Russia.

Thermatool Corp., East Haven, Conn., has received a contract from OCTG producer OMK for the delivery of two high-power HF welding machines and 12 postweld heat-treatment seam annealers to its Vyska Steel Works unit.

The equipment is scheduled to be commissioned later this year. Vyska Steel Works is the largest manufacturer of steel welded pipes in Russia.

The casing, line pipe, and tubing mills that will go online at Vyska will produce up to 7- and 10-in. pipe using both induction and contact welding with dual capability. The 7-in. mill comprises a 1,000-kW HAZControl™ technology HF welder and 2,000 kW of seam annealing induction power. The 10-in. mill is equipped with a 1,400 kW HAZControl HF welder and 3,200 kW of postweld heat treatment. Both mills also employ 250-kW end weld annealers.
