Pipe Heat Treatment Furnace Successfully Commissioned for Seamless Steel Pipe Processing

Project Milestone

Forever Electromechanical has completed full installation, linkage debugging and hot commissioning of its custom pipe heat treatment furnace for a seamless steel pipe manufacturer. The whole induction heat treatment line is formally handed over for mass production. The furnace is designed for oil casing, boiler tube and mechanical seamless pipes, performing normalizing, quenching and tempering in one continuous workflow. It solves common pain points including uneven wall temperature, pipe bending and unstable metallographic properties faced by traditional tube heat treatment workshops. This commissioning marks another successful overseas tubular project for Forever Electromechanical, supporting clients to meet API and international metallurgical standards for high-pressure seamless pipes.

IGBT Induction Power & Rotary Conveying Design

The core of this pipe heat treatment furnace adopts digital IGBT induction heating power supply, featuring high power factor and low idle loss. Different from chamber furnaces, induction heating delivers fast, inner-and-outer uniform heating for thick-wall seamless pipes. The rotary roller conveying mechanism keeps steel pipes rotating while moving forward, eliminating local overheating and minimizing pipe straightness deviation. Segmented induction coils and closed-loop infrared temperature sensors monitor temperature in real time, with temperature tolerance controlled within ±3℃ both on inner and outer pipe walls. Operators set processing parameters on the HMI touchscreen, saving multiple recipes for different pipe diameters, wall thicknesses and alloy grades.

Stable Metallurgical Performance & Low Deformation

Precise temperature holding and controlled cooling are critical for seamless pipe quality. The integrated quenching and tempering station adjusts water spray pressure and cooling speed automatically according to pipe specifications. After heat treatment, the seamless pipe achieves balanced strength and toughness, with reduced residual internal stress. Less oxide scale forms on the pipe surface, lowering material loss and subsequent cleaning workload. For high-demand oil casing and pressure pipeline tubes, consistent hardness and microstructure greatly reduce rejection rates and improve finished product yield. The system avoids excessive thermal deformation, a major defect when processing long-length seamless pipes in conventional furnaces.

24h Continuous Operation & Multi-layer Safety Protection

Built for heavy-duty industrial operation, the furnace is equipped with complete protection modules for overcurrent, overvoltage, water shortage and overtemperature. The water circulation cooling system stabilizes coil and power cabinet temperature during nonstop production. The modular layout simplifies routine maintenance, making coil replacement and component inspection faster. Compared with gas-fired furnaces, the induction furnace cuts energy consumption and eliminates flue gas emissions, complying with stricter low-carbon requirements in modern metallurgical plants. The whole line occupies less workshop area and can connect upstream pipe rolling machines and downstream straightening & testing equipment.

Customized Solution & Global Technical Service

Forever Electromechanical tailors furnace length, power rating and processing speed according to client’s target output and pipe size range. Before shipment, the full line undergoes 72-hour no-load and simulated thermal testing in factory. The engineering team provides one-stop service including technical drawing confirmation, factory acceptance, container shipment, on-site commissioning and remote after-sales support. Spare parts supply and periodic technical guidance are available globally.

Market Outlook

Growing demand for high-pressure seamless pipes in oil, gas and power industries raises higher requirements on heat treatment consistency. Energy-saving IGBT induction heating power supply will gradually replace old chamber furnaces. Forever Electromechanical continues optimizing induction heating and cooling control technology for tubular products. The company invites global pipe manufacturers for project consultation, quotation and factory inspection, to deliver reliable heat treatment equipment for seamless steel pipe processing.
