Avoid costly 和 hazardous infrastructure damage with im体育APP’s  Corrosion Under Insulation (CUI) inspection 和 testing services . Our ISO-accredited labs ensure reliable results 和 full regulatory compliance. 选择im体育APP提供精确、经济高效的CUI解决方案.

 

什么是CUI检验?

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. 当水分渗入绝缘材料时, 它创造了一个具有侵略性的环境，加速了腐蚀. 这种腐蚀通常在很长一段时间内都不会被发现, 对基础设施造成重大破坏, 哪一种修复起来既危险又昂贵. 在严重情况下, 这种损害可能导致昂贵的场地修复, 长时间停机, 以及法律问题.

 

CUI检验的好处

  • 安全增强: Ensuring the integrity of insulated equipment minimizes the risk of hazardous incidents, 保护人员和基础设施.
  • 法规遵从性:我们根据ISO 19277:2018提供广泛的测试服务, 包括热调节, 附着力测试, 人工老化, 热循环, 和 低温 曝光. This ensures that coatings 和 materials are thoroughly evaluated for performance under various conditions.
  • 运营效率: im体育APP's thorough inspection processes ensure continuous operation by maintaining the reliability of essential equipment, 减少意外停机.
  • im体育平台app下载经验: im体育APP’s team of experts provides valuable insights 和 support tailored to your requirements. 我们服务于一系列不同的im体育平台app下载, 提供定制的解决方案，以应对特定的im体育平台app下载挑战.
  • 定制的解决方案: im体育APP offers bespoke testing programs tailored for research 和 development, 包括替代材料的测试和改进的测试制度, 根据客户的独特需求提供具体的解决方案.

 

提供对你们材料完整性的全面评估, im体育APP offers extensive expertise in various corrosion testing methods, 包括 电化学腐蚀 testing alongside comprehensive Corrosion Under Insulation (CUI) testing. This ensures your products remain reliable 和 safe in diverse environments, 简化您在同一屋檐下的测试需求.

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

  • 热调节: 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. 
  • 人工老化: 环境 曝光 in the form of neutral salt spray 和 water immersion. 
  • 热循环试验: Repeated heating 和 cooling over multiple cycles from the maximum temperature of the relevant CUI category, 然后放入冷水中淬火.
  • 多相CUI循环腐蚀试验: A horizontal square pipe test is utilized to simulate a typical environment where CUI occurs; the test process includes dry heat, 热冲击, 浸泡在沸水中, 蒸汽接口, 关闭停机时间. 
  • 低温暴露: Optional cryogenic cyclic testing for cryogenic categories described in the st和ard.
  • 垂直管道试验(休斯敦管道试验): 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.
 

降低定期CUI检查的高成本

定期和彻底的CUI检查可能是昂贵的, 需要专门的设备和熟练的技术人员. The costs associated with unexpected repairs 和 replacements can be substantial, 增加了财政负担. 我们全面的检测服务, 如热调节和热循环试验, 确保涂料和材料的最佳性能, 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.

 

解决CUI检测中的可靠性问题

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, 这两者都具有重要意义. im体育APP’s CUI inspection services are built on a foundation of accuracy 和 reliability. 利用多种测试方法, 包括人工老化和低温暴露试验, 确保我们的检查提供一致和精确的结果.  Our experienced specialists follow st和ardized protocols in accordance with ISO 19277:2018, 减少假阳性和假阴性的风险. 通过提供可靠的数据, im体育APP enables you to make informed decisions about maintenance 和 repairs, 确保资源得到有效分配.

 

防护涂层对CUI预防的影响

作为预防CUI整体方法的一部分，具有保护性 涂料 是否经常与安装设计结合使用, 绝缘的选择, 检查制度. 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.
