All unfired and fired pressure vessel need annual overhaul and safety inspection.
In usual condition, the equipment has to be clean and open up for a yearly inspection.
The inspection will be on the pressure part and the essential fittings.
The pressure part inspection will mainly be on the corrosion, thickness and metal defect while the fitting will be on proper function.
The inspection can usually be extended by three months after written request to the related authority.
Yours faithfully,
Stephen Tsai
