Apparatus and method for maintenance of equipment using oil, gas and petrochemical plants

摘要

Maintenance unit of a refinery and petrochemical plant equipment in accordance with the present invention is a part of the insulation cover that covers the insulation As to the forming section to check presence or absence of a corrosive environment or in a configuration that combines the means for indicating the moisture content or moisture content or humidity of the ambient air containing insulation piercing the insulation hole from time to time, accidents due to corrosion and preventing the further prevention and corrosion by spraying a drying air or drying gas to be determined that the corrosive environment of the form, as well as the ancillary piping is not required since the excavation work for inspection at any time when buried in the ground no additional costs will occur, the initial installation costs because it is relatively inexpensive to apply to a large number of samples that form the risk of corrosion environment has the advantage of being able to check from time to time.
