成功案例: 管道法兰连接 - GPT Industries 法兰连接密封解决方案

案例分析 位于澳大利亚的一家油气运营商遇到了两个管道法兰连接泄漏的问题,这些法兰连接在安装后的几个小时内就出现了泄漏,因此他们联系了GPT Industries寻求法兰连接密封解决方案。 经过仔细检查,我们发现泄漏并不是来自法兰面,而是由于介质渗透通过垫圈的主体。 案例挑战 介质由60%含有甲烷(CH4)的甜气组成,导致管线需要立即关闭。停工给管道运营商带来了不断上升的成本。由于之前从未遇到过这个问题,并且成本不断增加,这个问题需要被认真对待并找到解决方案。 除此之外,为了保障系统的阴极保护程序,我们需要电绝缘的绝缘套件,垫圈的介电强度也需要尽可能高。 操作条件 温度:15℃ 压力:#300 介质:天然气 尺寸:2”(多个法兰)   解决方案 通过对实际情况的分析和运营商的研究,我们最终选择了EVOLUTION®作为解决方案。 GPT Industries已经多次遇到GRE垫圈介质渗透的情况。而使用EVOLUTION®能完美的避免这个问题,EVOLUTION®的设计中不包含GRE,使用的是完全包覆在专有涂层中的316L不锈钢核心。EVOLUTION®配备了获得专利的内径密封,能有效防止介质到达垫圈。同时,完全包覆的设计还具有提供高水平介电强度的额外优势,能达到1400伏/毫英寸。 安装了EVOLUTION®后,问题得到了解决,管线成功重新运行,绝缘也得以维持。   什么是EVOLUTION®? EVOLUTION®是一种获得专利的产品,是首款专为油气行业设计的完全包覆的绝缘垫圈,但同时也适用于许多其他行业。它是绝缘垫圈近35年来的最大技术进步!

海洋油气开发 - GPT Industries 海上油气开发密封方案

多年来,GPT Industries始终深耕于海洋油气开发环境中的绝缘产品研发,在海上油气开发过程中,无论是设计层面还是技术创新领域,始终保持行业引领地位。面对新的极端环境,我们开发出EVOLUTION®系列产品,专为海上油气开发密封方案量身打造,平衡成本与安全。接下来,让我们一同回顾一下具体的海上油气开发密封方案应用案例。   成功案例 早在2009年,一家石油公司计划在墨西哥湾深海区域、距离海岸200英里的位置开发一座储量高达10亿桶的大型油田。自2005年起,该油田便已开始采用原始的桁架式浮体进行开采。当时,最先进的ID Seal绝缘套件技术被应用于此,以保护绝缘套件的核心材料免受侵蚀性物质的侵害。 2015年,该油田的扩建计划得以落实。最终用户批准了项目,并将工程、采购和施工(EPC)合同授予了一家韩国公司。在EPC公司和最终用户的前端工程设计(FEED)阶段,GPT适时推出了EVOLUTION®绝缘套件,并详细介绍了其诸多优势。 实战经验的融会贯通 与此同时,GPT Industries还收到了另一家EPC公司的合作请求。该公司正为位于阿布扎比附近的阿拉伯湾设计一座油田平台,并急需一种适用于压缩机系统的防火绝缘套件。具体要求涵盖:防火安全、耐高温、3毫米厚的垫片,以及完全抵御侵蚀性海水环境的能力。此外,鉴于油田环境极为恶劣,存在高浓度的硫化氢,因此还需具备对酸性介质的顶级防护能力。 GPT Industries凭借与中东地区工程师多年的合作经验,深知该地区油田硫化氢浓度的持续攀升趋势,这是由于运营商正采用新技术从难以开采的油田中提取石油。EVOLUTION®系列完美契合了客户的全部需求,因此我们的EVOLUTION®绝缘垫片被选定用于该平台。 对于墨西哥湾项目的工程师而言,这些需求同样至关重要。他们同样对EVOLUTION®系统能够在整个平台上统一使用同一种垫片,并继续采用ID Seal技术表示赞赏。   显著优势 在这些项目中,EVOLUTION®展现出了以下显著优势: ID Seal解决方案:作为工程师们首选的预防性手段,已证实其能有效抵御侵蚀性介质的破坏。 “一型多用”解决方案:简化了备件管理,降低了维护成本。 垫片与绝缘套件组合:简化了安装流程,提升了可靠性。 完全封装、获得防火认证的绝缘部件 起初,EVOLUTION®垫片主要用于管道的铜镍合金消防系统的密封,其独特优势在于靠近孔口的低螺栓载荷要求,便于在软法兰材料上实现密封。随后,EVOLUTION®逐步拓展至管道系统的绝缘套件和换热器容器的垫片应用。 对于工程师而言,EVOLUTION®的另一项重要优势在于其尺寸与标准垫片一致,因此无需特殊设计即可轻松添加EVOLUTION®绝缘套件。相比之下,传统的VCS样式套件厚度为6.2毫米,无法直接满足标准管道设计软件的要求。 在设计和功能层面,EVOLUTION®系统助力两个项目的工程师们从容应对油田日益增长的需求。

电气桥接失效防护 - GPT Industries 电气桥接解决方案

电气桥接解决方案 法兰连接处的电气桥接,会导致绝缘失效。电气桥接一般是绝缘垫片导致的,但这种故障模式似乎正在增加。如果绝缘失效不是由于绝缘垫片本身,而是管道内的介质引起的,那么如何正确地进行绝缘呢?是否有一款绝缘产品可以解决这种故障模式? 观看下方视频,了解电气桥接失效解决方案! 什么是EVOLUTION®? EVOLUTION®是一款获得专利的产品,是首款专为油气行业设计的完全包覆的绝缘垫圈,但同时也适用于许多其他行业。它是绝缘垫圈近35年来的最大技术进步!

钢管防腐技术 - GPT Industries 海洋装载臂防腐解决方案

海洋装载臂,也称为机械装载臂、装载臂或MLA,是一种由铰接钢管组成的机械臂系统。它用于连接油轮、化学品船等油船与码头,实现货物(如石油)的安全装卸。 比起由软管连接装卸,海洋装载臂更适用于较大型船舶以及高装载速率和高压力的转运作业。海洋装载臂采用手动或液压控制,配备万向节,在一定程度上可以跟随系泊和船舶的移动。 许多装载臂系统都配备快速连接头,可以通过垫圈或O型圈来与船舶的集液管法兰适配,形成可靠密封。需要注意的是在断开连接之前,必须先排空或关闭装载臂系统。排空方式因传输介质而异:对于如燃气油、柴油等燃料,可采用高压空气吹扫管道;而对于煤油、汽油等燃料,则可通过泵抽空管道。 装载臂能够处理各种粘度和温度的液体和气体货物,从液态硫到液化天然气等货物均可通过海洋装载臂进行传输。海洋装载臂可为各种尺寸的船舶提供服务,从小型河船到最大型的超级油轮都在其服务范围之内。   海洋装载臂的极端挑战 由于海洋装载臂及其相关钢管长期暴露在海水、极端温度和腐蚀性物质中,极易受到腐蚀,尤其在钢管防腐方面更需高度重视。一旦腐蚀失控,可能导致灾难性的设备故障,因此,采用先进的钢管防腐技术并配合定期维护检查至关重要。GPT提供成熟可靠的海洋装载臂防腐解决方案,有效应对复杂环境下的腐蚀挑战,提升系统安全性与使用寿命。 可能影响装载臂的因素: 维护不足:若未能定期对臂体进行润滑或检查。 接触腐蚀性物质:铁矿石粉尘、氨等腐蚀性物质会对装载臂造成损害。 恶劣的海洋环境:盐水、极端温度和海浪的不断侵袭可能损坏臂体结构。 高使用强度:装载臂的疲劳和磨损可能会导致磨损和断裂风险增加。 异种材料结合:装载臂通常由不同材料(如碳钢和不锈钢)组成,可能导致电偶腐蚀问题。 鉴于其传输的介质特性,装载臂的法兰接头和绝缘垫片通常还需具备卓越的防火性能。 针对这些挑战,我们能为您提供了以下最佳解决方案。   Pikotek® VCFS® VCFS®内含可在815°C高温火灾中保持密封的二次密封元件,为标准的Pikotek® VCS®设计增添了卓越的消防功能。VCFS耐火绝缘垫片即使在恶劣环境下仍具有可靠的密封性能,还能通过API 6FB第3版的火灾测试。 由于其独特的密封激活机制(压力激活),该垫片所需的螺栓应力远低于其他类型的垫片。同时,设计精良的E型环将在正常工作期间作为二次密封发挥作用。而在发生火灾时,将作为主要密封元件,确保装载臂在极端情况下的安全运行。   EVOLUTION® EVOLUTION®是首款完全封装式的绝缘垫片。其薄3毫米的设计减少了大量安装较厚绝缘垫片时经常遇到的困难。完全封装的设计能保证垫片在水压测试下保持几乎无损的绝缘性能,确保了系统的稳定性和安全性。 这种创新的垫片采用GPT专有材料涂覆而成,该材料专为石油和天然气行业设计而成,具有极高的耐磨性和抗冲击性能。涂层还对H₂S、蒸汽、CO、CO₂以及石油和天然气管道中发现的其他化学物质具有出色的化学抗性,确保了垫片在各种恶劣环境下的长期稳定运行。 EVOLUTION®已通过多个尺寸和压力等级的API 6FB火灾测试,且操作温度远高于GRE产品。此外,EVOLUTION®还避免了GRE垫片常见的渗透问题或化学腐蚀问题,为用户提供了更加可靠和安全的解决方案。
