What is CUI 检查?

CUI (Corrosion Under Insulation) inspection helps identify corrosion that occurs under insulation due to 曝光 to moisture 和 oxygen. This type of corrosion typically affects insulated carbon 和 low alloy steel equipment operating at high temperatures in cyclic service within the CUI temperature range. When moisture infiltrates the insulation, it creates an aggressive environment that accelerates corrosion. This corrosion often goes undetected for long periods, causing significant damage to infrastructure, which can be hazardous 和 expensive to repair. In severe cases, this damage can lead to costly site remediation, prolonged downtime, 和 legal issues.

 

Benefits of CUI 检查

  • Safety Enhancement: Ensuring the integrity of insulated equipment minimizes the risk of hazardous incidents, protecting both personnel 和 infrastructure.
  • Regulatory Compliance: We offer a wide range of testing services following ISO 19277:2018, 包括 heat conditioning, adhesion testing, artificial aging, thermal cycling, 和 低温 曝光. This ensures that coatings 和 materials are thoroughly evaluated for performance under various conditions.
  • Operational Efficiency: im体育APP's thorough inspection processes ensure continuous operation by maintaining the reliability of essential equipment, reducing unexpected shutdowns.
  • Industry Expertise: im体育APP’s team of experts provides valuable insights 和 support tailored to your requirements. We serve a range of diverse industries, providing customized solutions to meet specific industry challenges.
  • Customized Solutions: im体育APP offers bespoke testing programs tailored for research 和 development, 包括 testing of alternative materials 和 modified test regimes, providing specific solutions based on unique client needs.

 

To provide a comprehensive evaluation of your materials' integrity, im体育APP offers extensive expertise in various corrosion testing methods, 包括 electrochemical corrosion testing alongside comprehensive Corrosion Under Insulation (CUI) testing. This ensures your products remain reliable 和 safe in diverse environments, simplifying your testing needs under one roof.

im体育APP offers a variety of testing to verify performance for suitability under insulation in accordance with ISO19277:2018, which include: 

  • Heat conditioning: Cyclic heat conditioning of coatings based upon the CUI category of choice. 
  • 粘连: Evaluation of heat conditioned 和 st和ard cured materials both pre 和 post-曝光. 
  • Artificial aging: 环境 曝光 in the form of neutral salt spray 和 water immersion. 
  • Thermal cycling test: Repeated heating 和 cooling over multiple cycles from the maximum temperature of the relevant CUI category, then quenching into cold water.
  • Multi-phase CUI cyclic corrosion test: A horizontal square pipe test is utilized to simulate a typical environment where CUI occurs; the test process includes dry heat, 热冲击, immersion in boiling water, steam interface, 和 shut downtime. 
  • 低温 曝光: Optional cryogenic cyclic testing for cryogenic categories described in the st和ard.
  • Vertical pipe test (Houston pipe test): An optional CUI test method to evaluate the resistance of a coating to accelerated CUI conditions with shut down periods. The test includes wet/dry/heat/cool cycling of an insulated coated pipe for a total of 30 cycles.
 

Reducing the High Costs of Regular CUI 检查s

Regular 和 thorough CUI inspections can be expensive, requiring specialized equipment 和 skilled technicians. The costs associated with unexpected repairs 和 replacements can be substantial, adding to the financial burden. Our comprehensive testing services, such as heat conditioning 和 thermal cycling tests, ensure that coatings 和 materials perform optimally, thereby extending the life of your infrastructure 和 minimizing maintenance costs. Investing in im体育APP's CUI inspections ultimately leads to cost savings by preventing severe damage 和 reducing the need for frequent inspections.

 

Addressing Reliability Issues in CUI 检查s

Ensuring the consistency 和 reliability of inspections across different inspectors 和 cycles can be challenging. The risk of false positives or negatives can lead to unnecessary repairs or missed corrosion, both of which have significant implications. im体育APP’s CUI inspection services are built on a foundation of accuracy 和 reliability. Utilizing a variety of testing methods, 包括 artificial aging 和 cryogenic 曝光 tests, ensures that our inspections provide consistent 和 precise results.  Our experienced specialists follow st和ardized protocols in accordance with ISO 19277:2018, reducing the risk of false positives 和 negatives. By delivering reliable data, im体育APP enables you to make informed decisions about maintenance 和 repairs, ensuring that resources are allocated efficiently 和 effectively.

 

The Impact of Protective 涂料 on CUI Prevention

As part of a holistic approach to CUI prevention, protective 涂料 are often utilized in conjunction with installation design, insulation choice, 和 inspection regimes. 在这种情况下, selecting an appropriate coating requires underst和ing the material's performance characteristics when subject to high-temperature cyclic 和 CUI conditions.
