Vessel Manufacturing
We design and manufacture pressure vessels and equipment for industrial applications. Depending on the project, designs comply with AD 2000, EN 13445, or ASME standards. Possible dimensions range up to 5 m in diameter and 150 t in unit weight.
Vessel and equipment manufacturing since 1952
Since 1952, Robert Josef Wolf GmbH & Co. KG has been manufacturing pressure vessels and equipment made of carbon steel, stainless steel, and other materials. Depending on the project, designs comply with AD 2000, EN 13445, or ASME. Our plants in Wilnsdorf and Herdorf have the necessary manufacturing and testing capabilities.
In-house quality assurance (QA)
Our quality assurance team inspects production in-house. The specified testing procedures and 3D measurements are defined on a project-by-project basis. Our documentation team compiles material certificates, manufacturing records, and test results into comprehensive project documentation.

Frequently Asked Questions About Industrial Vessel Manufacturing
Here, we answer technical questions regarding design, dimensions, and regulations in industrial vessel manufacturing.
Which standards does WOLF follow in its manufacturing? + − We manufacture pressure equipment in accordance with AD 2000 or EN 13445 in conjunction with the Pressure Equipment Directive 2014/68/EU. For ASME projects, ASME Code Section VIII Division 1 with a U-stamp and Division 2 with a U2-stamp apply. Our welding process is certified according to DIN EN ISO 3834. EN 1090 applies to load-bearing steel beams; our quality management system is certified according to DIN EN ISO 9001.

What sizes and pressures are possible? + − We manufacture vessels up to 5 meters in diameter and, as single-piece units, up to 50 meters in length. Unit weights up to 150 metric tons and wall thicknesses up to 100 millimeters are possible. Conventional pressure vessels are designed on a project-specific basis for pressures up to 400 bar. For hydrogen applications, tube-bundle storage systems can be designed for pressures up to 500 bar. Larger components can be manufactured in transportable sections.
