Apr 15,2019 A survey of defects in pressure vessels built to high#0183;Pressure vessel inspection,or pressure vessel testing,involves non-destructive tests that ensure the integrity of a new pressure vessel or on previously installed pressure equipment that has been altered or repaired.In the early days of pressure vessels,many pressure vessels were over-pressurized,and they would explode.Some results are removed in response to a notice of local law requirement.For more information,please see here.SECTION .0100 - DEFINITIONS 13 NCAC 13 .0101(c) pressure vessels contracted for or installed before January 1,1976; (d) hydropneumatic storage tanks contracted for or installed before January 1,1986; and (e) boilers or pressure vessels to which the ASME Code is not intended to apply,other than those boilers and pressure vessels to which the term North Carolina Special applies.
