Inspection of Pressure Vessels and Boilers
Pressure Vessels, Boiler & Piping
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and fatal accidents have occurred in the history of pressure vessel development and operation. DARLSCO has specialized Engineer(s)/ technicians to carry out the Inspection, Testing and Certification of Air Compressor, Air Receivers, heat exchangers, accumulators, industrial pressure vessels covers, auto clave and boilers.
DARLSCO competent to carry out Functional test and safety accessories test of any pressure equipment. DARLSCO conducts periodic Inspection includes but not limited to Functionality test, Internal test and Integrity test ( to examine the external and internal surface conditions), Proof Test( to evaluate the resistance of pressure performed using Water (hydrostatic test ) / Air ( Pneumatic test) & other Non-destructive Testing (if required) recommended standards as approved by Dubai Accreditation Centre (DAC), Dubai Municipality (DM) & Dubai Civil Defense (DCD) of the pressure equipment.
