Coating systems for tubes

Thanks to the reliable engineering, superior quality, and advanced design of its technology, SAET EMMEDI is today a leading specialist in the manufacture of complete turn-key coating lines for tubes.

Providing effective protection against the corrosion of steel pipes used for the construction of pipelines is crucial to avoid undesirable onsite repairs or replacements.

Emmedi's induction heating systems for coating applications grant a perfect uniform heating prior to the application of the coating layers. The systems are powered by solid state IGBT converters, which ensure a consistent and proper heat treatment of the full tube body at the required temperature. The system consists of one static inverter unit, a control desk, a set of coils, a pyrometric temperature control system and a closed – circuit distilled water cooling unit. An inductor support bench for a correct adjustment of the coil is also available on request.

Technical features

- Output power and operating frequencies optimized according to production requirements.
- IGBT based I-Power inverter working at proper frequency.
- Size of the inductors are calculated according to the range of pipes to treat.
- Pyrometer for temperature control.

Advantages

- Independent heating units for increased operational flexibility. Possibility to treat pipes with different OD on the same line.
- Precise temperature management thanks to the closed loop PID system, comparing the requested set point with the actual temperature read by the pyrometer.
- Independent power control for each heating head (PID).

Featuring advanced proportional control capabilities, all SAET EMMEDI coating lines deliver both superior quality and process integration.
