Stainless Steel
Tanks & Vessels

Inotec provides high-quality stainless steel vessels and tanks for brewery, diary, beverage, food processing, pharmaceutical and chemical industries. The design and execution of the process and storage tanks are performed in accordance with the highest hygiene standards used in the food industry.


The fabrication technology of the tanks is based on a new vertical system for tanks manufacturing consisting in:

  • Automatic coil rolling, cutting and vertical welding system
  • Vertical weld coil grinding machine
  • Tank assembly, automatic circular welding and weld grinding system


For conical ends manufacturing the following machines are used:

  • Cutting and bevelling machine
  • Cone forming and manufacturing rolling machine
  • Automatic seam weld machine


To fulfil the high-quality hygiene standards, the internal and external welds and surfaces are polished using automatic CNC polishing machines for tanks ends and for complete vessels.


Inotec is able to design and produce pressure vessels with PED 97/23/EC,AD 2000-Merkblatt HP 0, EN 13445-4and EN ISO 3834-2 certification.



Internal and external surface finishes can be done according to beneficiary requirements. The welds and surface finishing of the tanks and vessels are performed by automatic grinding and finishing NC machinery.


Inotec’s experienced installation team can provide high quality mechanical installation works and insulations for food, beverages, diary, chemical, detergents and cosmetic plants. Our mechanical fitters and welders are qualified to use methods and technologies that ensure a fast and reliable installation.


Inotec welders are TÜV certified according to PED 2014/68/EU and EN ISO 9606-1 to perform mechanical installations of process and utility pressure piping in the following domains:

  • Process piping. 25 mm ≤ DN ≤ 500 mm, -50°C ≤ T ≤ +440°C, Pmax ≤ 40 bar
  • Utility piping. 32 mm ≤ DN ≤ 800 mm, Tmax ≤ +440°C, Pmax ≤ 40 bar. The welders are qualified for WIG and MIG/MAG procedures.
  • Stainless steel piping fabrication. For pipes preparation, cutting and beveling Orbitalum GF machines are used. They work on the “Planetary Cutting Technology” principle resulting in a perfect perpendicular cut.

The welding of the stainless-steel piping is performed according to Tungsten Inert Gas (TIG) procedure, with internal inert gas purge.

If it is needed, automatic orbital welding ORBIMAT is also available. After welding, the external welds are cleaned, pickled and passivated. The internal welds are cleaned and treated by recirculating a passivating agent.


Insulation materials


Cold insulation: Flexible Elastomeric (Armaflex) / Cellular Phenolic Foam / Foamglass / Polyurethane (PUR)


Hot insulation: Mineral wool (Rockwool) / Fiber glass / Ceramic Fiber / Perlite / Calcium silicate / Foamglass


Cladding materials


Stainless steel cladding 0.4 – 0.8 mm assembled with rivets or self-tapping screws
Stainless steel cladding 0.4 – 1 mm assembled with rivets or self-tapping screws
Stainless steel closed fully welded insulation 2 – 2.5 mm

Insulation piping fabrication


Proper insulation installation for piping is critical to its effectiveness. Before insulation, the pipe must be cleaned, dried and protected with anti-corrosive coating. The insulation material is installed over the pipe by wrapping (blanket, sheet), by foaming (PUR) or by snap-fitting (insulation preformed). All longitudinal and circumferential joints must be sealed using the self-seal lap and butt strips.


If a vapor barrier (retarder) is required for the insulation, a protective foil is applied completely adhered to the insulation. The cladding is fitted over the insulated pipeline by means of rivets or self-tapping screws. For maintenance, the valves are insulated with removable insulation boxes.

Quality control


Quality control (QC) is set of procedures and methods intended to ensure that a manufactured product or performed service adheres to a defined set of quality criteria or meets the requirements of the customer.


All products and services provided by Inotec are quality controlled during on-going manufacturing,finally inspected before delivery and monitoring during operation.


For quality control during products manufacturing and during on-site installation, advanced measurement instruments and testing methods are used.

Video endoscopy


The video endoscopy is performed for internal visual inspection of pipe systems. Video endoscopy equipment contain a small camera which detects the image and transmits the signals recorded to a video processor from where the signal is sent to a monitor. The electronic sensor is placed in the tip of a flexible fiber-optic cable. The cable can have lengths up to 30 meters and with a diameter down to 6 mm. The QC engineer can easily detect non-conformities in the welds. The picture of the weld can be saved.

Hydrostatic tests


Hydrostatic test or pressure test is a method to test pressure vessels and pipelines for strength and leaks. The test involves filling of the vessel or pipe systems with gas – usually air -, or liquid – usually water -, and pressurization of the system to the specified test pressure. The liquid pressure testing is performed using a hydrostatic test stand consisting in pressure supply pump and instrumentation. The leaks and pressure losses are identified. Hydrostatic tests contribute to maintain safety standards and durability of the vessel or pipeline over time.

Dye-penetrant tests


Dye penetrant inspection (DP), also called liquid penetrate inspection (LP) is a widely applied and low-cost inspection method used to check welding surface defects such as cracks, surface porosity, leaks and fatigue cracks. Large number of welding seams can be inspected rapidly and at low cost. By this method only surface-breaking defects of the welds can be identified.

Non-destructive testing (NDT)

Includes a variety of analysis techniques to assess the properties of the materials and the accuracy of assembly without causing any damage to the material.


Welding control of thin-walled pipes is usually done by radiographic X-ray or gamma-ray testing. The goal is to reduce the number of defective welds as low as possible.

Turn Key

Inotec is able to provide high-quality products, process units and plants that are designed, supplied, built, fully installed and ready to operate. This kind of approach is commonly requested for new projects or upgrading of existing production facilities to extend the customer’s plant capacity and performance.


To manage turnkey projects involves complex integrated activities relevant to engineering, procurement, prefabrication, construction, start-up and commissioning. The goal is to integrate management, engineering, manufacturing, execution and implementation resources to achieve specific project goals and meet specific success criteria at the specified time.
