UHP Coaxial Tubing
AMETEK Cardinal UHP’s Coaxial Tubing is a premium solution designed to meet the rigorous demands of ultra-high purity (UHP) applications, particularly in industries where the control of contaminants is critical. This coaxial tubing features an advanced double-wall design, which significantly enhances protection against leaks, corrosion, and external contamination. By incorporating an outer tube surrounding an inner tube, the coaxial design provides an additional safety layer, making it ideal for transporting high-purity gases, chemicals, and other sensitive media.
Ultra-high purity stainless steel coaxial tubing is commonly used in semiconductor manufacturing, biotechnology, pharmaceuticals, and other high-tech industries where maintaining contaminant-free environments is crucial. In semiconductor fabrication, for instance, impurities or particulate matter introduced during gas delivery can lead to costly defects and downtime. Coaxial tubing helps mitigate these risks by offering an extra barrier to protect the purity of gases and chemicals as they move through the system. Additionally, it prevents leaks, which is critical for ensuring process integrity and maintaining the stringent cleanliness standards required in cleanroom environments.
The benefits of coaxial tubing include superior corrosion resistance, enhanced safety through leak prevention, and improved durability under extreme temperature and pressure conditions. Ultra-high purity stainless steel (such as 316L) is often used for its non-reactive surface, ensuring that gases or chemicals being transported remain uncontaminated. Furthermore, coaxial tubing can be easier to install and maintain compared to traditional tubing systems, making it a cost-effective choice over the long term.
AMETEK Cardinal UHP’s Coaxial Tubing is available in various materials and configurations, allowing customization to meet the specific needs of different UHP systems. Whether used for gas delivery, chemical transport, or other UHP applications, this tubing offers unmatched reliability, performance, and protection.
