Offshore

NIRAS has supplied induction bent pipes to the offshore market since the early nineties. There are many good reasons for using induction bending as often as possible. The most obvious is the reduced cost of producing a pipeline, but as soon as you get used to the practicalities of induction bending you will keep seeing further advantages. For instance, you can increase the radius of the bend quite seamlessly, bringing advantages such as better flow and reduced internal wear. The overall result will be reduced operational costs from a reduction in pump force and lower maintenance costs because the bends will need replacing less often. From a design point of view, you do not need to be tied to one specific radius; we can steplessly adjust the radius from 1,5D (1,5 times the nominal outside diameter of the pipe) all the way up to 22,000 mm. You do not even have to plan your pipeline with 45° or 90° bending angles; using induction bending we can seamlessly produce any desired angle from 1° to 270°.

 

As demands for quality in the international manufacturing and offshore industries increase, so do the requirements for quality assurance and documentation. The more bends and welds, the higher the documentation costs. By using induction bending you can eliminate many welded joints, thus also reducing the volume of testing and documentation. Automatic quality surveillance during the bending process assures high quality and reduced documentation costs. Using advanced instrumentation, all stages of the bending process are documented.

 

The computer prints out temperature and other parameters to document that the bending has been carried out according to specifications. Wall thickness and ovality are also carefully monitored so as to satisfy normal requirements for standard bends. All data is stored and can be used later for similar operations.
