Your trust is our duty: Flexible production processes, an extreme high level of vertical integration, qualified employees and advanced technical know-how enable us to meet even the highest demands. An effective quality and appointment management ensures reliable and punctual execution.
Our engineers and technicians from the fields of plant planning, engineering, project management, construction, production and service ensure the highest quality standards. We are certified to ISO9001-2008, ASME BPVC section 8 division 1 and AD 2000 leaflet HPO / DIN EN ISO 3834-3.
The most recent certification according to the current standard ISO 9001: 2015 was carried out by TÜV Rheinland in June / July 2019. The certificate states that a management evaluation of the company has been performed, in which the suitability, adequacy and effectiveness of the company’s quality management system has been verified and found in accordance with the established standards.
Customer feedback, process performance, improvement requests, corrective actions and the results of audits were included as well as the appropriateness of resources and the handling of opportunities and risks. Köllemann GmbH has the performance of its quality management system regularly audited by independent certification bodies.
ASME BPVC certification section 8 division1: The ASME Boiler and Pressure Vessel Code, or ASME code, is the world’s leading set of rules for the design, manufacture and testing of pressure equipment and components. It regulates all requirements for pressure-bearing components with regard to material, calculation, production, testing, inspection, testing, certification and overpressure protection. The rules are issued by the American Society of Mechanical Engineers, the Association of American Mechanical Engineers, comparable to the German VDI.
The ASME stamp on our nameplate certifies that our products meet the requirements of the ASME Code and the required safety standards. Components manufactured according to the ASME Code are recognized not only in the US, but in more than 100 countries worldwide. Köllemann’s products can thus be used worldwide. Our products have long been compliant with these standards. In Germany, fewer than 225 companies have ASME code certification.: Köllemann is ASME certified since 2004.
Certification to EN AD 2000-Merkblatt HPO / DIN EN ISO 3834-3: Köllemann GmbH is certified by TÜV Rheinland according to AD 2000-Merkblatt HPO and DIN EN ISO 3834-3, so we meet the welding requirements for the production of pressure vessels according to the Pressure Equipment Directive 97/23 / EC. This ensures that Köllemann GmbH has the following prerequisites:
