In order to meet specific production requirements for the Russian oil and gas industry, Italy-based Faccin has launched HAV-2P, a NC-controlled high-performance pipe mill bending rolls, to support the production of pipes delivering productivity, repeatability and automation of the entire process
These pipe production bending rolls are constructed with extremely sturdy electro-welded structures and are fitted with three rolls in thermally treated steel alloys.
Pipes production technology is an area of such complexity that only companies with many years of experience and high technology background can safely and reliably work in and deliver machines suitable for the most challenging projects.
Faccin SpA has many years of experience in the design and manufacturing of special machines, both standard and customised, for the production of pipes.
Using the latest technology, the company follows from its 60,000 sq m facility in Visano, Italy, the construction of the machinery at every stage, from receipt of the order to design by the in-house engineering department, from construction of electro-welded structures to machining of structures and forged rolls up to assembly, shipping, installation and training.
The rolls of the special HAV-2P bending rolls are moved independently – the top roll moves vertically, the lower rolls move horizontally – and allow the power of the machine to be fully exploited, depending on the various thicknesses to be rolled.
According to the company, to offer high performance in the production of long pipes with relatively small diameters, the lower rolls of the HAV-2P bending rolls are supported by backups for their entire length. The top roll is preloaded to compensate for the flexion during plate bending and may be replaced quickly to extend the range of diameters and thicknesses that can be obtained by rolling.
HAV-2P long bending rolls are designed for rolling plates generally from five to 45 mm thick, ideal for producing pipes up to 18m long and diameters from 15 inch to more than 60 inch, complying with technical specifications, tolerances and quality of the API standards.
For further increase the production speed and automation, Faccin also proposed an accurate post-bending machine that prepares the pipe for welding and a series of outboard motorised guide rollers that control the movement of the pipe from the HAV-2P to the post-bending machine and successive working stations.
For specific customer projects, Faccin’s professional engineering and R&D department designs and produces customised solutions that aims to effectively suit the requirements of the most exigent pipes producers.
