A full range of services
Design and consulting
Ocem offers its experience and technical expertise to its customers from the very first stages of project development.
Our team can support every customer request, analysing the best execution and construction solutions using calculation and 3D modelling software.
In our extensive history, we have built large steel structures for various industrial sectors. In the last few decades specifically, we have specialised in the amusement parks, oil & gas and food industries, as well as both major public and private works.
Control, traceability and preparation of materials
The first operational stage is the control, approval and preparation of the materials in accordance with the most stringent quality procedures.
This stage is fundamental in the construction of any type of structure, as the conformity and traceability of the materials (both qualitatively and quantitatively) are the starting point in a production process that ensures we supply products that are durable and safe.
The finished work is always certified at the end of each stage. Only then is the material ready to move on to the next stage.
3D cutting
Our MPC350/SPC1000 is a 3D tube profiling machine that uses the plasma or oxy-fuel cutting technique.
The machine receives the data in CAD/STEP format directly from the 3D software and can cut round, square or rectangular tubes. It is able to cut all the required shapes simply, quickly and precisely. The machine also produces all the chamfers needed for subsequent assembly and welding.
The oxy-fuel cutting process uses an acetylene flame and a jet of pure oxygen. It is based on the principle that ferrous materials containing a sufficient quantity of carbon, when heated until incandescent, burn in an oxygen-rich atmosphere: the iron oxidises in a highly exothermic chemical reaction. The oxy-fuel process can only be used with steels that have a 0.12%-0.25% carbon content.
Oxy-fuel specifications
Minimum wall thickness: 3 mm
Maximum wall thickness: 70 mm
Cutting angle: -70° to 70°
Plasma cutting uses a plasma torch: the gas is blown at high pressure, creating an electrical arc between an electrode and the surface being cut that transforms the gas into plasma. The plasma transfers heat to the material until it melts. The kinetic energy of the gas expels the molten metal from the cutting area, thus allowing the operation to continue. The plasma moves at over 15,000 km/h (more than twelve times the speed of sound).
Plasma cutting specifications
Minimum wall thickness: 3 mm
Maximum wall thickness: 20 mm
Cutting angle: -45° to 45°
Assembly, welding and final checks
Construction and assembly
In our large production facilities we are able to assemble all types of structures in a linear sequence, from sub-assemblies to the complete final assembly, before subsequent welding. The possibility to complete full or partial assemblies on multiform constructions allows better and more accurate inspection of tolerances and any deformations.
Welding
We are especially proud of the quality of our welding procedures. These have continued to improve over the years, requiring in-depth knowledge of the shrinkage and deformation processes of metal structures. Our staff is qualified in all welding processes, with licenses certified by notified bodies.
NDT
We can carry out all types of NDT (non-destructive testing) on the welds. Based on specific customer requests, we use techniques including ultrasound, magnetic particle testing, penetrating liquids, X-rays, or simply certified visual inspection.
Machining, painting, galvanising, testing
Where requested, we also manage the machining, painting, galvanising and final testing stages. We also complete the assembly by adding all the mechanical parts for the electrical and plumbing systems to the constructions.
Packing and shipping
Finally, we handle all the shipping procedures for delivery to the customer. This stage requires specific expertise in logistics and customs procedures. Indeed, it is not simply a matter of guaranteeing safe transport, but also involves providing consulting on special and multimodal transport in EU and non-EU countries, with complex customs regulatory implications.
