ASME-READY STAINLESS STEEL VESSELS FOR THE WATER TREATMENT INDUSTRY

Yes. THIELMANN has extensive experience supporting international industrial supply projects. For U.S. customers, we coordinate manufacturing and delivery with clear project communication, technical alignment, and documentation support. Many customers prioritize securing the right vessel specifications, material quality, and certification pathway over local sourcing to ensure performance and compliance.

THIELMANN supports companies at the forefront of industrial water treatment and process applications. Our clients include original equipment manufacturers (OEMs), system integrators, engineering teams, and industrial project stakeholders such as Envirofalk, Orben, or NSI. Our vessel solutions are ideal for applications requiring pressure resistance, stainless steel construction, and reliable manufacturing quality in the pharmaceutical, chemical, food, and energy industries, among others.

Absolutely. Often, projects begin before all vessel details are finalized, so our engineers support customers during the technical review stage. During this stage, we determine whether a standard vessel is sufficient or if modifications are necessary. This includes reviewing application conditions, fittings, pressure requirements, documentation needs, and overall system integration.

Our most standard vessel configuration is 6 bar (87 psi) with a 237 mm diameter (9.3 in). For projects requiring U.S. code alignment, vessels can also be supplied with ASME marking for pressures of up to 10 bar (145 psi). Higher-pressure solutions may also be possible above 10 bar, depending on the specific design and project requirements. In those cases, the applicable certification pathway would need to be reviewed and confirmed by our team based on the final specification.

Stainless steel maintains structural stability and chemical resistance over extended service life, supporting predictable performance under repeated handling, cycling, and exposure. For most chemical environments, this contributes to system continuity and reduced lifecycle interruption.

Because they can help simplify the compliance review process. In U.S. drinking water applications, project teams must increasingly consider the regulatory framework around wetted materials and components, including the EPA lead-free requirements and the NSF/ANSI/CAN 61, NSF/ANSI/CAN 600, and NSF/ANSI/CAN 372 standards. As these expectations have become more demanding, many customers look for solutions that reduce validation effort, documentation risk, and approval complexity. Stainless steel supports that approach by limiting dependence on internal coatings while maintaining the durability, hygiene, and mechanical performance required in demanding water treatment applications.

Response times depend on the complexity of the project, the requirements of the vessel, and the scope of the documentation. Our team reviews application details for standard and modified vessel inquiries and collaborates closely with customers to provide clear technical and commercial responses as efficiently as possible.

Stainless steel is the durable, sustainable choice and the ideal alternative to plastic or fiberglass containers. By providing a robust and reliable solution for the storage of chemical substances, THIELMANN’s containers play a crucial role in preventing spills and leaks of hazardous liquids, directly contributing to environmental safety.

What’s more, customers can rely on stainless steel’s durability again and again. Despite the higher initial overhead, a stainless steel container’s long service life reduces the need for replacements, promoting greater resource efficiency and superior ROI. Once the container comes to the end of its usable life, it’s 100% recyclable, promoting a circular economy.
