Induction and Hybrid Heating Systems
Interpower Induction has pioneered a heating process that incorporates the best of electric and gas energy This Hybrid System provides particular advantages for tube and pipe operations because of the improved metallurgy, greater flexibility, higher production and reduced operational cost.
When there is a need for a variety of OCTG products or to adapt to changing market demand, Interpower offers a superior solution using induction for pre heating (electric) and furnaces for large volumes (gas). Our hybrid systems are inherently flexible, more cost effective and provide superior metallurgical results.
There is no need to slow production to achieve a change in quench profile. Interpower systems set the flow and pressure in different zones from the control desk. This ensures the correct heat transfer for each size and grade of pipe.
The benefits of our exceptional heating and quenching systems are further enabled through advanced controls. Heating and quenching recipes are based on established models and refined through experience. Trending errors are easily observed and corrected on the fly. Data is collected on critical parameters and customers can see the process their product went through. Diagnostic assistance minimizes downtime.
Adding induction preheat to existing gas furnaces has proven benefits in both energy savings and increased productivity. A company recently installed Interpower induction systems prior to its austenitizing and tempering furnaces. After the install, they achieved a 50% increase in production while improving metallurgical homogeneity and straightness. In addition, there were significant savings in energy costs.
Line Pipe Coating – Dry and Coat
The rapid heat from induction is ideally suited to drying line pipe prior to shot blast and for pre heat to cure fusion bonded epoxy and other coatings. One pipe is sufficient to set the system and coating can begin on the second, ensuring rapid start up. The low air temperature allows for low melting point pipe connectors to mask pipe ends safely and the absence of flame improves the safety close to the powder coating booth. Interpower offers systems for on-shore line pipe coating and bend coating.
Pipe Upset – Preheat
An Interpower pipe end heater rapidly and efficiently provides the temperature profile necessary for an accurate upset without excessive heating of the surrounding environment. Systems for medium and high volume production are available.
Pipe Handling/Material Handling
Interpower has capabilities for all material handling components for pipe processing with or without associated heat or quench systems. This includes loading tables, transfer mechanisms, walking beam conveyors, driven skewed roller conveyors, cooling tables etc. All systems are custom designed for your space.
