This paper mainly introduced the Chinese codes and standards of glass-lined pressure vessels. The manufacture and major maintenance of pressure vessels shall be subject to supervision and inspection by the authorized inspection institutions in accordance with the safety technical codes. Design, materials, weld, nondestructive testing, glass-lined process, hydrostatic test and leak test were investigated. In addition, test specimens for calculating wall thickness, Welding Procedure Qualification and Glass-lined Procedure Qualification were analyzed. TSG R7004-2013 Regulation on Supervision Inspection for Pressure Vessel specifies Glass-lined Procedure Qualification shall be carried out before glass-lined. Glass-lined procedure qualification is used to control temperature range, heating rate, holding time, and cycle times. The glass-lined process is absolutely critical to the longevity of the glass-lined vessel.
