ARIANNA

ARIANNA is an orbital automatic welding system created for all pipeline related applications including pipes with great wall thickness and connections.

ARIANNA is controlled by an industrial PLC that allows great application flexibility and to obtain the best welding in any work conditions and on any type of steel. The purpose of all this is to maximize the production, guaranteeing high quality standards of the welded joint.

ARIANNA is an open automatic system that allows interfacing with multiple devices, that is welders or external wire feeders, through analog or digital interfaces, and allows welding technicians and engineers to adapt the system, in the best way possible, to the position that needs to be performed.

Applications

System Components

The importance of fast, accurate and uniform heating as part of the pipeline welding specification has grown significantly. This has resulted from the increased use of heavy wall pipe and modern automatic and semi-automatic welding systems 0n/off shore pipeline.

The benefits of the induction heating system are:

Pipeline Induction Heat’s pre-weld induction heating systems have been designed for both onshore and offshore field operation, at mainline / front end or double jointing locations. Originally engineered for use on large diameter heavy wall pipes, in association with automatic welding systems, induction pre-heat is equally useful where manual stick-welding is being employed during cold weather conditions.

Re-Heat
In certain circumstances, particularly for offshore fast production pipe lay using automatic welding systems, unexpected delays can disrupt the welding process on the lay barge firing-line.

These ‘hold-ups’ can lead to degradation of the partially welded joint, which may require further filling before it is fully completed. To prevent degradation and embrittlement of the weld, which could lead to a negative NDT / X-ray result down line, VillaMacchine have designed a re-heat induction heating system. This consists of a hinged coil designed to pass heat into the localised area of the weld margin only.

Post Weld Heat Treatment

The post-weld induction heating system is intended for lay barge operation, for diameters ranging from 6″ to 72″, with no limit on wall thickness. Temperature ranges are typically 0 to 650°C.

The purpose of induction post-heating is to provide a rapid, accurate heating cycle, to stress-relieve (anneal) a recently welded pipe joint. This is typically required following specialist automatic welding of very heavy wall pipe, which can result in embrittlement of the weld metal, leading to unacceptable ‘hardness values’. To overcome this problem, the weld area must be subjected to a pre-calculated heat treatment programme, within the fast lay-barge welding production cycle.

The Villa Macchine’s Pipe Facing Machines are the fastest cutting, most versatile, and user-friendly machines on the market today. Years of experience and the highest quality components are incorporated into every unit.
The machines are powered by a hydraulic circuit as pipe layer.
The PFM machines are designed to machine complex bevel required by automated pipeline welding systems, in addition the machines can be used for:

The machines have two major parts, the clamping section and the machining section. The clamp section has two sets of hydraulically powered clamping shoes that are designed to work equally and simultaneously.
The machine is secured to the pipe by expanding the clamp shoes inside the pipe on PFM’s range from 8″ to 90″ pipe. The machining sections of the machine consists of a rotating faceplate with four or six tool holders each holding tungsten carbide cutting tips.

The tools can be set a wide variety of bevel designs and wall thicknesses, Each tool holder may cut a different bevel angle simultaneously .

The PFM operation take from 2 to 6 minutes depending on pipe wall thickness and experience of the operator.

The following documentation will be supply with the machine:

Standard Features

The Pneumatic Clamp is used for a correct centering and alignment of pipes.

For the translation, the machine can be provide of axial piston air motor and equipped for manual or automatic welding system.
Its operational cycle is carried out with special pneumatic valves, that in production stage, are controlled manually or at a distance with an appropriate control rod.
