HF Welding Simplified for Diverse API Product Manufacturer

One of the World's largest suppliers of ERW pipes has completed the installation of a new 800kW HAZControl™ Technology Dual (induction/contact) Solid State HF Welder at one of their North American facilities. Dedicated to serving the growing demand of the global oil and gas industry, the North American producer chose Thermatool to meet API standards required by their customers.

The organization has a wide product matrix of API products ranging from 4.5" to 8.6" OD and 0.188" to 0.500" wall pipe. The manufacturer chose Thermatool’s HAZControl™ Technology Welder software for the ability to select HF weld power and frequency in ±1kW and 1kHz increments, resulting in industry leading heat input control during welding. To maximize up-time during product change-over, the predictive algorithm built into the HAZControl™ Technology software guides operators to the initial heat settings. When a product has been tested and proven successful, the software allows operators to store and then easily recall welding recipes so HF welding variability is reduced and repeatability is achieved regardless of operator know-how or shift-to-shift operations.

The Dual welding option offers the manufacturer many product options with the flexibility of using two welding processes, induction or contact, on one welding system. This gives the pipe producer the ability to achieve significant power savings when welding large diameter pipe with High Frequency contact welding, yet still choose the induction welding process when needed.

With the new equipment in place, the manufacturer can reliably produce high quality API and Proprietary Grade pipe to meet the growing demand of the global oil and gas industry.
