Mechanical engineering
From technical requirements to practical solutions
At RvS Group, we design and deliver smart, safe, and future-ready solutions for piping systems, equipment, and steel structures. We transform technical requirements into practical, buildable designs that comply with all relevant codes, standards, and industry best practices.
Functional design
Functional design forms the link between process requirements and detailed mechanical design. It defines how installations, systems, and components should operate within the specified constraints and requirements. A well-developed functional design provides the foundation for reliable execution, safe production, and efficient integration into existing processes.
This expertise is essential for new installations, plant modifications, and optimization projects, ensuring that designs fully comply with all technical, operational, and safety requirements.
Our Services
Our team translates process requirements and project objectives into a clear and well-defined functional design. This includes:
- Defining design requirements based on process requirements and customer specifications, ensuring compliance with relevant standards such as ISO 9001 and VDI guidelines.
Preparing technical specifications for components, piping systems, tanks, and process equipment
Creating flow and layout diagrams to visually represent system functionality
Applying relevant standards and guidelines for safety and hygienic design, including EHEDG guidelines
Collaboration with customers and engineering teams to ensure alignment, verification, and validation
Executing scenarios and simulations to verify functional performance and system behavior
Identifying and mitigating potential risks during the design phase
Our approach
We work systematically based on customer requirements and process data. Our design team combines technical analysis, simulations, and practical experience to assess multiple scenarios and develop the optimal solution. The results are reviewed with stakeholders and translated into clear specifications and engineering drawings. Through continuous validation and collaboration, we ensure that every design is practical, safe, and future-ready.

Calculations
Engineering calculations are the foundation of reliable and safe mechanical designs. Through systematic pressure and mechanical strength calculations, stress analyses, and heat loss evaluations, we ensure that components and installations meet functional requirements, performance criteria, and applicable safety standards.
This expertise is essential for the design, modification, and expansion of tanks, piping systems, heat exchangers, and other process equipment.

Design verification and review to ensure compliance with applicable codes, standards, and design requirements
Identifying risks such as overpressure, material fatigue, and thermal overload conditions
Our approach
We start by analyzing design data and process parameters. Through scenarios and simulations, we assess loads, pressure conditions, and thermal performance. All calculations are verified and documented in engineering calculation reports. Design verification and peer reviews ensure that assumptions are well-founded and that the final design is technically robust, compliant, and safe.
