At the company where he is employed, they manufacture various pressure vessels and tanks from stainless steel and special materials. The company is largely self-sufficient, which means they produce the entire product in their own facility, from design, cutting, welding to machining and various surface treatments (pickling, passivation, sandblasting, painting).

Problem

At the company where he is employed, they manufacture various pressure vessels and tanks from stainless steel and special materials.

Solution and Method

The company is largely self-sufficient, which means they produce the entire product in their own facility, from design, cutting, welding to machining and various surface treatments (pickling, passivation, sandblasting, painting). They are aware that with the right approach, quality and comprehensive solution, they can remain competitive in today's market. In addition to many different products, the company also deals with the manufacture of heat exchangers for the chemical, pharmaceutical or food industry.

They mostly manufacture exchangers from stainless steel, of various sizes and volumes, and with different numbers of tubes. They offer a comprehensive solution in production, from strength calculations and design to final machining and pressure tests. Over time, the manufacture of heat exchangers in their company has developed, and they use newer manufacturing technologies in welding and machining.

With their use, they have managed to bring production to a new level and make the entire manufacturing process in a shorter time and with fewer errors in welded joints. In the diploma thesis, he will present the complete manufacture of a pair of heat exchangers used in the pharmaceutical industry. He will describe how material specification, material ordering and exchanger design, material cutting and bending, and assembly and welding proceed, with particular focus on orbital welding of tubes into tube sheets.

He will also present the machining of individual positions and the final product, as well as the pressure test. He will research new technological solutions for potentially faster manufacture of individual assemblies in machining and locksmith work. He will try to shorten the time of the entire manufacture of the exchanger, so that we do not lose quality in the process, but even try to raise it to a higher level, and in this way try to increase production efficiency.

He will show in more detail the machining of turning and milling, and drilling of the exchanger tube sheets, and the pressure test after completion of the exchanger manufacture.
