Design
-
NIWA has its own team of engineers with extensive experience in the design of a broad range of industrial equipment, including pressure vessels according to the PED / ASME / UKCA / TR CU, heat exchangers, reactors, mixers per the MD / ATEX and all kinds of tanks according to customer requirements, as well as auxiliary structures (ISO 14122, EN 1090).
-
In addition, on the Polish market we deal with supervised tanks subject to UDT inspection for hazardous media according to RMG, including manufacture, repair and modernization, as well as measurement equipment pursuant to requirements of the Polish Main Office of Weights and Measures.
-
We strive to always provide our customers with the best possible design in terms of functionality and safety, always adhering to cost savings.
Technical documentation is created on the basis of the provided technical sheets or existing designs/ equipment; we also cooperate with the customer in order to develop new projects on the basis of initial concepts.
Documentation is made mainly according to the following standards:
- EN 13445
- ASME BPVC Section VIII Div 1 (ASME stamp with U designation)
- EN 14015
- WUDT-UC
- PD 5500
- if necessary we use FEA analyses
We can also develop documentation according to:
- AD-2000 Merkblatt
- API 650
- EN 12952
- EN 12953
- EN 13480
Beside norm requirements and upon agreement, we implement customer specifications, as well as additional special requirments of bulletins/ auxiliary standars, e. g.
- nozzel loads (WRC 107, WRC 297, EN 13445, PD5500),
- fatigue analyses,
- wind/ snow and seismic loads acc. to Eurocodes or national codes,
- special requirements concerning materials for equipment operating in acidic environments (NACE MR0175, NACE MR0103, ISO 15156 norm series) exposed to diverse corrosive phenomena.
A dedicated engineer is assigned to every order; who sooperates closely with the customer, ensuring the execution of all design and special requirements. He is present at every stage of equipment production, providing a real opportunity to fully optimize the project.
Before the purchase of materials and prefabrication of the device, the technical documentation is checked in terms of execution possibility and conformity to all required norms and specifications of the customer by the project conformity team (designers, process engineers, quality controllers) and a third party (notified body, ASME inspector, customer inspector), if required.
The engineers operates with the latest versions of design software (calculations and selections)
- PV Elite – by HEXAGON
- Visual Vessel Design – by HEXAGON
- Product Design & Manufacturing Collection by AUTODESK (made up of ca. 50 items, incl.: Inventor Professional, Fusion 360, Vault, Autocad Mechanical, Inventor Nastran).
Documentation is created in Polish-English as standard, however, it is possible, to provide it upon agreement in any language version.
Documentation is provided as:
- Flat documentation in any format, e.g. dwg, dxf, pdf,
- 3D model in any format of the dedicated software,
- 3D browser-readable model (no additional software necessary).
