Quality for transporting fluids

The tube is found in a wide variety of industrial sectors. Those named all feature the possibility of conveying sensitive or specific fluids. These fluids therefore require quality installations.
Creating a tubular circuit involves assembling straight tubes with elbows, T-pieces, flanges and valves among other components. In most cases assemblies are welded but crimping by sleeving is also an option, for example. Nevertheless, the welded assembly normally offers equivalent, and frequently superior, characteristics over the material making up the tubes themselves. They are therefore today considered the ideal solution. Different types of welding can be applied depending on the use and above all the characteristics of welded materials: steels, stainless steels, titanium, austenitic steels and tube thicknesses.

The most widely used welding process for stainless steels is TIG - Tungsten Inert Gas - as it controls the bath extremely well and is therefore very suitable for precision welding.

Junctions created in this way are virtually the only places in the installation where problems like leaks, micro-fissures, corrosion and mechanically fragile points can occur. Depending on the significance of the fluid conveyed and also the characteristics of the installation, mainly pressure, the junction points and the welds must be controlled properly at execution as well as in the traceability of welding parameters.

  • Chemical products: chemical industries
  • Petroleum by-products: petrochemical industry
  • Water, fuel and air: aeronautics industry
  • Steam: energy, nuclear and solar industry
  • Petroleum and gas: gas and petroleum industry

AXXAIR product range

AXXAIR has therefore made a point since 1997 of offering machines capable of quality preparation and orbital cutting and also square to perfect standard cuts on thin tubes up to 3 mm thick. We also offer bevelling machines for the thicker tubes to enable controlled quality welding.

AXXAIR supports its customers in the global cutting, squaring, bevelling and orbital welding process in over sixty countries worldwide.

We place the emphasis on service in this process, which is increasingly customer-centred. This starts with determining the welding parameters in pre-sale phase including the preparation. We then subsequently train the personnel on the equipment to ensure users are capable of dealing with the applications they will have to manage by themselves.

Axxair orbital technology

Orbital welding and orbital TIG welding generators

When the weld is created automatically by an orbital welding machine, for example, the machine is capable of recording the actual welding parameters at any time and therefore of documenting each weld precisely. The qualification is also in this case necessary but the machine, once calibrated correctly, can repeat very high quality welds. The welder can therefore apply his knowledge to controlling the weld and the welding process.
