ASTM C27000 Common Brass Seamless Tubes For Low Temperature
Pipeline In Oxygen Plant
1. Description
The performance of ASTM C27000 in brass tube is outstanding, such as good thermal conductivity, good thermal conductivity and low strength. This brand of seamless brass tube is usually used to manufacture heat exchange equipment (such as condenser, etc.). It can also be used for the assembly of low temperature pipeline in oxygen plant. Small diameter copper pipe is usually used to transport pressure liquid (such as lubrication system, oil pressure system, etc.) and pressure pipe as instrument.
