Type L ASTM B88 Copper Pipes and Tubes

MediStreams Oxygen Medical Copper Pipelines is a manufacturer of Type L ASTM B88 Copper Pipes and Tubes, which are designed to provide reliability, resistance to corrosion, and durability of water and gas systems in addition to HVAC systems. These pipes are made of phosphorus-deoxidized copper (C12200) that meets the standard of the ASTM B88 of seamless water-tube copper. Type L is an intermediate-wall thickness and therefore would be suitable in cases of interior water pipes, plumbing and general-purpose applications where strength and flexibility are all needed.
