PASCA&MERCK公司介绍:
公司成立于1999年,有一组在密封技术领域有深厚经验的专家融合过去100多年的密封历史组建而成,工厂坐落于德国的Darmstadt。
高性能金属密封公司,简称PASCA&MERCK公司,设计、研发并制造弹性金属密封圈:
金属O型圈;
弹簧增强型金属O型圈;
金属C型圈;
弹簧增强型金属C型圈;
另外还提供金属E型圈,金属Oysterseal和金属Commaseal密封圈。
PASCA&MERCK弹簧增强型金属密封圈是当前世界上最先进的全金属高性能密封圈之一,随着工业的快速发展,今天很多应用对密封的要求远远超出了传统密封圈所能承受的温度、压力及泄露率的要求,PASCA&MERCK独特的多层结构及客户化设计为能满足这些高端的密封要求提供了可能:
能达到最低的垫片泄露率,用氦气检测泄露率可达10-9atm.cm3/s.mongoing不同(30年只泄露不到一立方厘米氦气);
多种不同材料可以选择,可设计用于各种不同的工况的垫片,最高承受1500bar压力,1200℃的高温以及最低4K的超低温;
根据客户需要,可以做成几乎任何形式和尺寸;
金属接触金属的密封方式保证了对密封系统的严格控制;
极长的使用寿命,可设计使用寿命超过40年。
PASCA&MERCK专注于金属密封圈市场,产品应用涵盖几乎所有领域,包括:航空航天,核电及电子能应用,石油化工,特种阀门,工业自动化,医疗设备,真空领域等。
质量控制:
PASCA&MERCK生产制作的金属密封圈是在严格的技术规范要求下进行的,公司获得了ISO9001认证,而这一质量体系又严格按照欧洲EN9100规格。
焊接设备由计算机自动控制
O型圈焊接后的100%LP试验
X-射线检测焊接结果
专业自动化的氦气测试设备
专业自动化的密封圈加载及回弹试验设备
如图所示,内压型金属C型圈,外径最小6.48mm
