Any equipment has a designed service life, and pressure vessels are no exception, but how many years is this service life? 8 years, 10 years, 15 years, or even longer? Today we will talk about this issue in detail. Environmental protection boiler manufacturer

The design service life of a pressure vessel is not necessarily equal to the actual service life. I believe it is easy for everyone to understand that the design service life is the service life given under normal or ideal conditions, but the actual service life will be affected by The influence of various factors, so there may be differences between the two.

For chemical equipment: main equipment such as towers and reactors are generally no less than 15 years, and ordinary vessels and heat exchangers are no less than 8 years.

For petrochemical equipment: Fractionating towers, reactors, high-pressure heat exchanger shells and other difficult-to-replace containers or components have a design life of no less than 20 years; ordinary vessels, heat exchanger shells and tube boxes are generally no less than 10 years -15 years.

The design life of the pressure vessel is just to remind users that when the pressure vessel exceeds the design life, its safety factor will be reduced, and the safety level rating will also be reduced. At this time, necessary guardianship measures should be established and the inspection cycle should be shortened.
