Tubo e condotto
The tube and pipe manufacturing sector is responsible for fabricating hollow sections of various geometries—circular, square, and rectangular—which find extensive utility across construction, the oil and gas industry, automotive manufacturing, HVAC systems, civil infrastructure, and general industrial production. These critical products are derived from a diverse array of metallic compositions, encompassing carbon steel, stainless steel, aluminium, copper, and specialized alloys. Production methodologies include both seamless and welded formats.
Parameters such as dimensional precision, material strength, inherent corrosion resistance, and optimized process speed are paramount. Regardless of whether the operation involves forming, welding, coating applications, or heat treatment, manufacturers necessitate consistent and scalable heating solutions. This is precisely where induction heating emerges as an exceptionally potent and transformative tool.
How Induction Heating Supports Tube & Pipe Production
Induction heating offers fast, efficient, and controllable heat for continuous processes like welding, annealing, coating, and forming. It’s ideal for inline production lines and allows for real-time control with minimal thermal waste.
