Cojafex supplies machines for all types of pipelines. The larger models, such as the PB850, PB1200, PB1400 and PB1600 are mainly used for transmission pipelines and the smaller models, such as the PB200R, PB400R and PB600 for other types.

Cojafex pipeline bending machines have a high degree of automation. Cojafex machines are equipped with special start/stop systems, which guarantee a smooth transition from straight pipe to bend. Induction power is automatically controlled based on precise temperature measurement. Temperature scanners ensure, that the highest temperature in the heated zone is actually measured. It is particularly important with CLAD pipes (e.g. INCONEL-CLAD) , Duplex and the higher X-grades, to keep the bending temperature within narrow limits to prevent damage to the material structure.

The excellent Cojafex process control ensures that bends can consistently meet the highest requirements with minimum effort.

The pipeline bending machines can be equipped with a fully automated tangent heating system. This allows you to heat the straight tangent in the same way as the bend. This way the material properties of the bend and the straight tangents will be comparable.

This is especially important when the pipes/bends need to be heat treated after bending, as is often the case for transmission pipe lines made of higher X-grades materials such as API – 5L X70, API – 5L -X80 and API – 5L X100.

In order to limit the ovality of the bend pipes are often braced from the inside with steel or wooden supports. Putting in and removing these braces is labour intensive work. Cojafex' automated ovality reduction systems introduce forces in the vertical direction to reduce the ovality of the bend within the limit of the relevant specifications without braces.
