Pipe fittings for special geometries, small batch sizes, all materials
In apparatus and mechanical engineering, standard solutions are often insufficient. Individual designs, tight tolerances, and small quantities require a manufacturer who produces flexibly and provides technical input.
Requirements of the Apparatus and Mechanical Engineering Sector
Requirements for pipe fittings are as individual as their areas of application. Standard solutions quickly reach their limits—especially in demanding industries such as energy, chemicals, or plant engineering.
Requirements range from complex geometries outside common standards and tight dimensional and shape tolerances to the economical production of small and medium batch sizes. At the same time, short delivery times, a wide variety of materials, and complete documentation and traceability are crucial—especially for pressure-bearing or safety-relevant applications.
Implementation is always carried out in compliance with relevant regulations such as AD 2000, the Pressure Equipment Directive 2014/68/EU, EN 13480, as well as EN 10253 and ASME B16.9. Inspection certificates according to EN 10204 are also frequently a fixed part of the requirements.
This is exactly where Nirotec comes in.
We combine specialized manufacturing expertise with a deep understanding of technical requirements and standards—realizing even complex custom solutions reliably, economically, and on schedule.
What Nirotec Supplies for Apparatus and Mechanical Engineering
Through our own forming production—cold and hot forming, hydroforming processes—we can realize geometries that others cannot produce or cannot produce economically. In addition, we procure all other piping components for a project from a single source.
Typical Areas of Application:
Plant and machinery piping
Apparatus engineering (vessels, heat exchangers, reactors)
Custom designs with non-standard dimensions
Prototypes and small series
Spare parts production for existing plants
Test benches and pilot plants
