Vessel Production | Apparatus Production

AMS Technology's production is structured strictly according to technological criteria. Individual production units have ample space at their disposal, optimizing internal logistics and warehousing.

The cutting branch includes, in addition to the round and tube material cutters, the 3D plasma cutting robot for cutting and chamfering of vessel heads and flat sheet metal.

The pre-fabrication branch is attached to the cutting section. All shell rings are manufactured in this section on several roll bending machines and welded to a complete cylinder. Conical heads are also, amongst other things, manufactured in this section with the aid of additional sheet metal forming machines and equipment.

Machining is set up as an independent production unit and supplies the pre-fabrication section and vessel production by manufacturing order specific components, such as vessel flanges.

The grinding branch will polish or grind the individual parts surfaces to the required roughness as far as their relevant condition allows it.

Those pre-fabricated components are now put together, aligned and welded together X-ray-proof in the vessel manufacturing branch. Also all other remaining jobs are carried out in this section, such as the aligning and welding on of nozzles into the pre-made openings, the fitting and installation of legs or support brackets, installation of the heating or cooling system and all other installations and fittings that require welding. If later in the production process further grinding or polishing work is required, then the unfinished vessel is once more processed through grinding section.

Quality assurance will then carry out pressure and tightness checks for pressurized vessels.

Once all checks are positive, acid cleaning will clean the surfaces from tarnishes and oxide scaling until the surface is homogeneous.

The completed vessel can then be insulated in the vessel production branch – if necessary – and completed with the other add-on parts such as stirring units, sensor systems, valves etc. and packaged for shipping.

Overview of our branches of production:

• 3D-Plasma cutting / conventional cutting
• Prefabrication / component fabrication
• Machining / stainless steel processing
• Grinding / surface finishing
• Vessel production / apparatus production
• Series production / welding assemblies
• Quality assurance / quality control
• Acid cleaning / pickling
• Packing / shipping

We use two modern roll bending machines to bend coil sheet metal or steel sheets directly into vessel shell rings. These can have a maximum diameter of 4,000 mm (13.12 ft) and a maximum length of 3,000 mm (9.84 ft). Finally, they can be welded into cylinders or cones.

In addition to the roll bending machine, we also use other machines for sheet metal forming. This includes a “Kraftformer” for border crimping conical heads and a swing-folding machine for edge bending. Additionally, we possess hydraulic presses, a hydraulic profile bending machine and a copy punch.

Conventional Cutting, Plasma Cutting, Separating

The cutting branch is responsible for order-specific cutting of round and tube materials and cutting of steel sheets for the prefabrication and vessel production branches. It is located as an "island unit" in the semi-finished parts warehouse. We have modern electro-mechanical metal band saws at our disposal to process cutting orders and a hydraulic plate shear for straight sheet metal cuts.

3D Plasma Cutting: Video

Plasma cutting: Plasma cuts are executed using a high-precision, state-of-the-art 3D plasma cutting robot.

Using the 3D automatic plasma cutting unit, it is also possible to perform three-dimensional cuts. Vessel heads and flat sheet metal can be cut and chamfered in the machine with the aid of two separately manoeuvrable cutting tables with a dimension of 4,270 x 4,120 mm (14 x 13.5 ft). AMS Technology: Plasma cutting with highest precision.

Machining is set up as an independent production unit and supplies the pre-fabrication and vessel production branches. It manufactures order-specific components, such as vessel flanges or bushings.

Our machinery includes a universal milling machine and a manual console milling machine. Additionally we use several (servo-) conventional turning machines and one CNC radial drilling machine.

Process, Pressure, Mixing and Storage Vessels and Apparatus

The vessel production branch is organized into porduction islands. Here, the prepared and prefabricated components coming from the branches cutting, prefabrication, grinding, machining and pickling (in cases where prepickling was required) are assembled, aligned, fitted and then welded in an X-ray-proof fashion.

Additionally, all further jobs that require welding are carried out here: production, aligning and welding of nozzles into the pre-made vessel base openings / holes, fitting and installation of legs or support brackets, installation of the heating or cooling system and all other installations and fittings.

Once all jobs are complete, the vessel has to go through the grinding area again. There, we remove all processing marks and finally create requested surface roughness. Subsequently, the vessel is acid cleaned / pickled at the processing marks. Then the vessel is moved to quality control, where it is checked regarding its dimensional accuracy and pressure resistance as per the requirement specifications. For pressurized vessels, the measurements are documented for the Technical Control Board (TÜV) approval.

Once the final checks are completed, the vessel is then insulated (where required), cleaned and rendered passive. The vessel is then prepared for transport by sea or truck and dispatched according to customer specifications.

The grinding section is located in a 540 m² (5,812 sq. ft.) large separate hall area. Two filter systems clean and recirculate the air and ensure that no dust particles spread to the adjoining production section.

We have available more then ten manual working spaces for individual grinding and polishing works. Modern belt grinding machines are used for the internal and external grinding of vessels and heads as well as for the execution of cylindrical grinding works. A double belt grinding machine is installed for grinding, matting and polishing flat surfaces.

Our pickling plant is specifically designed for vessel and appliance production. Our acid dip tank has dimensions of 6,500 x 1,800 x 1,800 mm (21.3 x 5.9 x 5.9 ft.) and a volumetric capacity of 20 m³ (5,283 gal.). This enables us to acid clean even large components. We also offer acid cleaning as a contracting and sub-contracting service.

Complete vessels can easily be sprayed with acid in our acid cleaning room with a size of 140 m² (1,506 sq.ft.). Tracks connect the acid cleaning room with the production hall. It also has its own crane system.

Goods Receipt Control | Ongoing Control | Pressure Tests | Final Inspection

A tremendous amount of checks are required to meet the ever-increasing requirements on surface quality and higher general requirements in the food and pharmaceutical sector.

Our independent quality control department checks and controls all our products in great detail. In addition to a permanent quality control and production approval for our products, we also ensure consistent goods receipt control for all third-party components. This way, we can guarantee and maintain our high quality standards.

Our inspectors use state-of-the-art technology to ensure objective and technically correct evaluations. We use measuring devices for surface roughness, wall thickness and ferrite content. Additionally, we check for material mix-ups with a metal spectrometer and conduct gas measuring.

After a final acceptance test (FAT) by our customers or by ourselves at AMS Technology, we move swiftly. We deliver ex works or, if required, load our goods on trucks of customer organized transport companies. We can also organize the complete transport from our site to the destination including all requirements.

We organize truck transports, special transports, air or sea freight packed under canvas covers or sea-worthy in wooden boxes or containers. We work with professional packing and transport companies. Just-in-time completion, preventive packing, loading and delivery are all understood.
