API 600: Design & Specification of Bolted Bonnet Steel Gate

API 600: Design & Specification of Bolted Bonnet Steel Gate udemy course

API 600 II Gate Valve II Various Clauses II Valve design

This course is designed to offer in-depth knowledge of API 600, the key standard governing bolted bonnet steel gate valves used in the petroleum and natural gas industries. These valves are specifically intended for severe service conditions involving corrosion, erosion, and high-pressure environments—requiring full port openings, heavy wall sections, and robust stem designs.

The course covers all essential technical requirements, cross-references with relevant API and ASME standards, and detailed design features including stem types, wedges, bonnet design, valve internals, and fugitive emission controls. It also includes a case study on bonnet thickness calculation to enhance practical understanding.

This course is ideal for piping engineers, valve designers, QA/QC professionals, and engineering students aiming to enhance their expertise in valve specification and design compliance.
