ISO, OSHAS Standards &Certifications



To Quality, Safety, The Environment and Society


We are proud to hold and maintain ISO 9001. As the internationally recognized standard for Quality Management Systems (QMS). ISO 9001 is the most widely used QMS standard in the world, with over 1.1 million certificates issued to organizations in 178 countries. ISO 9001 provides a framework and set of principles that ensure a common-sense approach to the management of any organization to consistently satisfy customers and other stakeholders. In simple terms, it provides the basis for effective processes and effective people to deliver an effective product or service time after time.


Our ISO-9001 Quality Assurance Program along with the Certification of ASME Section VIII, Div. I and Div. II, Section I and PP insures that the packages we design and manufacture meet the requirements of our clients. This is achieved by multiple, intensive inspection and testing.


The ASME sets out stringent guidelines and requirements for the fabrication, installation and use of pressure vessels. EN-FAB is a leader in the manufacture of vessels that both adhere to ASME code and meet our customers needs.


EN-FAB pressure vessels are provided with the following stamps and registered with The National Board of Boiler and Pressure Vessels Inspectors:
