Pipe fittings for chemical and process plants
We supply pipe fittings for chemical plants, petrochemicals, pharmaceuticals and the process industry – from our own production and targeted sourcing, in all relevant and corrosion-resistant materials, with complete documentation.
Requirements in the chemical and process industry
In the chemical and process industry, piping components are continuously exposed to high mechanical, thermal and chemical loads. Accordingly, their design is subject to strict codes and standards that clearly define material selection, design and manufacturing.
International standards such as ASME B31.3 and EN 13480 form the basis for industrial piping systems, supplemented by national codes such as AD 2000 and the European Pressure Equipment Directive 2014/68/EU. In H₂S-containing or corrosive environments, standards such as ISO 15156 (NACE MR0175) or NACE MR0103 are also applied to reliably prevent material failure.
For applications with increased requirements for cleanliness and process safety, such as in the pharmaceutical or food industry, additional guidelines such as EHEDG or ASME BPE are also taken into account.
What Nirotec offers in the chemical and process industry
With our own forming production and targeted sourcing, we deliver flexibly – from standard components to custom solutions to drawing.
Our components are used in:
Process piping for aggressive and corrosive media
Reactor and column piping
Basic chemicals and petrochemical plants
Pharmaceutical process plants
Fertilizer and ammonia synthesis plants
Chlorine and acid plants
Exhaust gas cleaning and flue gas desulfurization
Materials & designs
Material selection depends on the medium, temperature, pressure and applicable code:
Austenitic stainless steels: 1.4301 · 1.4307 · 1.4404 · 1.4435 · 1.4571 – standard materials for most process applications
Duplex & Super Duplex: 1.4462 (UNS S31803) · 1.4410 (UNS S32750) · 1.4501 (UNS S32760) – for chloride-containing and sour-service environments
6Mo & high-alloy steels: 1.4547 (UNS S31254) · 1.4529 (UNS N08926) – for aggressive chloride and acid environments
Nickel alloys: Alloy 625 (2.4856) · Alloy 825 (2.4858) · Alloy C-276 (2.4819) / Hastelloy C-276 – for extreme applications with hydrochloric acid, sulfuric acid, hydrofluoric acid
Creep-resistant steels: 16Mo3 · 13CrMo4-5 · P91 – for high-temperature process piping
Material selection is project-specific – with advice from our technical sales team on request.
