Design Of Unfired Pressure Vessels (UPV)

Introduction To Unfired Pressure Vessels

Under the Factories and Machinery Act 1967, each unfired pressure vessel must have a valid certificate of fitness (CF) before it can be operated. For this purpose, approval for the design of the unfired pressure vessel has to be obtained in advance from the Department of Occupational Safety and Health (DOSH) before it fabricated, installed or used.

Application for approval of the design may be made by the manufacturing company, installer, supplier or owner of the unfired pressure vessel. Local manufacturers of unfired pressure vessels must register as a manufacturer with the department.

The following are several examples of unfired pressure vessels that require design approval:
