API electro-welded tube mills

The FIMI Group designs, manufactures, and installs plants for the production of API electro-welded pipes. The lines are manufactured with production speeds and thicknesses according to the customer's specifications and have a single motor drive on each profiling shaft. This makes it possible to control the speed on each shaft with extreme precision and to adjust the ratio between upper and lower speeds so as to avoid sliding on the strip surfaces. Here are the main technical features:

• tube diameters: 13.0 - 508.0 mm;
• material thickness: 0.3 - 16.0 mm;
• tube lengths: 500 - 20.000 mm;
• working speed: 0 - 150 m/min;
• maximum weight of coil: 30 Ton.

Strip accumulators and preparation units
The strip preparation unit has the task of welding the head and tail of 2 coils for non-stop production. The whole cycle can also be performed in fully automatic mode. The correct feeding of the strip during the coil joining operation is managed by the spiral accumulator. The infeed section runs faster than the roll forming unit giving the correct buffer to weld head and tail.

Flying shears
FIMI lines are equipped with the most cutting-edge flying shear systems to guarantee excellent performance in terms of productivity and blade life. The flying shears are designed for cutting API electro-welded pipes in a range of diameters from 13 to 610 mm. Available as single-blade (small diameters), double-blade (medium/large) and four-blade orbital (large diameters) units for cutting pipe on the fly.

Units can also be supplied individually for replacement or integration into existing production lines. For further information >>
