Medical gas, compressed medical air, vacuum | ASTM B819 |
Copper UNS No. C12200 | ASTM B819
CerropureTM ACR/AMN/OXY/MED (Type L) tube is specially cleaned, nitrogen charged, and capped (white) by robotics to prevent contamination.
ACR/AMN/OXY/MED (Type K) is also specially cleaned and capped (green) for use in medical gas systems and meets the same allowable residue limit of 0.0035 g/sf of interior tube surface area.
Pressurizing with nitrogen reduces formation of oxides during brazing. Reduction of oxides reduces system
contamination.
Copper TubeFor Fuel Gas Applications
For over 40 years, gas companies in the U.S.A. and Europe have used copper for fuel gas piping. Some advantages of using copper in fuel gas piping include:
- Flexibility
- Ease of bending
- Compact sizing
- Ease of joining
- Resistance to corrosion
Note: Plumbing and mechanical codes govern what types of products may be used for applications. Local codes should always be consulted for minimum requirements. Our alloy C12200 seamless copper tubing is manufactured in the U.S.A. and is produced in compliance with the applicable chemical and mechanical properties of ASTM standards.
