Consulting & Feasibility Study
The Process specifications – which media will flow through the pipes and which materials are to be used – come from you or your engineering firm. We will review these specifications. Feasibility, provide indications for optimal implementation and development Suggestions for safe and efficient Integration.
Production
In our own workshop, we manufacture stainless steel pipes and piping components to the highest quality and safety standards. Only certified welders work in this process, utilizing modern techniques such as orbital welding. Each component undergoes standard procedures, is inspected, and can be fully documented upon request. so that it can be seamlessly integrated into your system.
Montage
Our installation teams reliably install the piping systems on site – in close coordination with your project manager. This ensures... clear handover protocols, test reports and Security concepts the smooth process and optimal handling.
Documentation
We will deliver to you upon request and by arrangement a Complete, auditable documentation – including material certificates, weld seam verifications, and test documents. This creates transparency and meets the high compliance requirements in the chemical, pharmaceutical, and refinery industries.
Service & Extensions
Even after project completion, we continue to support you as needed: with expansions, modifications, or adjustments during ongoing operations. This ensures your piping system remains reliable, efficient, and safe – for many years to come.
We exclusively use stainless steel pipes, as this material meets the highest requirements for safety, hygiene and durability.
From certified welders and visual inspectors to documentation experts: Our employees work according to internationally valid norms and standards.
We supply piping systems that meet the high quality standards of the chemical, pharmaceutical and energy industries – documented and auditable.
For over two decades, we have been a partner for complex projects in Germany and other countries. Customers from the chemical, power plant, and industrial sectors rely on our expertise and our commitment to integrity.
1. Analysis
You provide us with your drawings or a flowchart – the planning is your responsibility or that of your engineering firm. Our task is to translate these specifications into concrete designs. technical feasibility to check. We comment on open points, clarify details regarding media routing, the handling of pressure, steam or liquids, and ensure that all Requirements clearly defined .
2. Strategy
Based on the analysis, we will develop a detailed proposal. Revisions and adjustments will be documented in an audit-proof manner, ensuring clarity about the current status at all times. The goal is an approval that provides you with planning security and forms the basis for our work. smooth implementation offers.
3. Implementation
Once approved, the manufacturing of your pipelines and systems begins. Our certified welders work with state-of-the-art technology such as... Orbital welding and tested procedures. In parallel, your permanent project manager The management of the entire process – from material logistics to construction site coordination. This ensures stable schedules and clearly defined interfaces.
4. support
Upon completion of the installation, you will receive complete documentation, as agreed upon: Material certificates, weld seam verifications, test reports. These documents are auditable and meet the highest quality and safety standards. Upon request, we can also support you in the long term – with adjustments, expansions, or modifications during ongoing operations.

"Our pipelines must be resistant to the media – failures are not an option."
➜ We exclusively use high-quality stainless steel, tested and documented according to international standards. For every medium – whether liquids, gases, or steam – we select the appropriate piping system and ensure maximum resistance to corrosion and stress.
"We need complete documentation for our chemical plants."
➜ Upon request and by agreement, we provide you with 100% documentation. Every weld is documented, every pipe is accompanied by material certificates. This ensures you meet audit and compliance requirements – from internal quality assurance departments to international regulatory inspections.
"Space in the facility is limited – we need tailor-made solutions."
➜ With precise prefabrication and 3D planning, we create pipelines that integrate perfectly into existing structures. This minimizes conversion times and enables smooth operation – even in complex systems.
"Our processes run under pressure or with steam – safety is our top priority."
➜ Our certified welders and experienced project managers work according to the highest safety standards. Piping systems are pressure tested, leaks are ruled out, and all relevant safety documents are prepared.
"We need a partner who also handles projects across Europe."
➜ STW operates not only in Germany but also in other countries. With experienced teams, intercultural project experience, and clear certifications, we reliably support you in European projects.
