Question 1

What is the difference between soft annealed and hard drawn copper tubes?

Accepted Answer

Soft annealed (O60) tubes are flexible and easy to bend for field installation, while hard drawn (H80) tubes maintain structural rigidity for applications requiring straight, stable piping. The hard drawn series is supplied in 3M straight lengths for central AC, VRF, and rigid piping systems.

Question 2

What standards do the ACR hard copper straight tubes comply with?

Accepted Answer

The hard drawn tubes are produced from C12200 (TP2) phosphorus-deoxidized copper and comply with GB/T 1527, GB/T 17791, and ASTM B75 standards. Each tube is 100% eddy current tested and supplied with a Mill Test Certificate (EN 10204 3.1).

Question 3

What sizes are available for the ACR hard copper straight tubes?

Accepted Answer

The hard drawn straight tubes cover OD sizes from 1/4 inch to 2-1/8 inch in standard 3M lengths. The H80 temper maintains straightness during transport and installation, and the tubes are compatible with R22, R410A, and R32 refrigerants for HVAC and refrigeration applications.
