Capillary copper tubes are copper tubes with extremely thin inner and outer diameters. They are widely used in household refrigerators, electric freezers, high-precision instruments, electronic equipment and instruments, etc. The material commonly used is high-quality copper such as TP2 and TU1, which has excellent thermal conductivity and corrosion resistance.
Application Scenarios
① Refrigeration system: Capillary copper tubes are widely used in small-sized Freon refrigeration devices with a capacity of less than 10KW. By changing the length and diameter, they can meet different working conditions and cooling capacity requirements;
② Gas transportation: Applicable to water cooling projects and environmental protection projects, etc.;
③ Daily life: In building water supply systems, capillary copper tubes are widely used due to their good thermal conductivity and high low-temperature strength.

Frequently Asked Questions (FAQ)
What makes C10100 oxygen-free copper different from regular copper?
C10100 is a high-purity copper grade with a copper content of at least 99.99% and extremely low oxygen levels. This makes it highly resistant to hydrogen embrittlement and provides superior electrical and thermal conductivity compared to standard copper grades.
What are the primary applications of capillary copper tubes?
Capillary copper tubes are primarily used as metering devices in refrigeration systems (refrigerators, freezers), gas transportation lines, water cooling projects, and high-precision instruments due to their precise dimensions and high thermal conductivity.
What standards do your oxygen-free copper tubes comply with?
Our C10100 oxygen-free copper tubes are manufactured in strict compliance with major international standards, including ASTM B187, GB/T 1527, and GB/T 2040.
Can these copper tubes be easily bent and welded?
Yes. Thanks to their high purity and outstanding ductility (with elongation ≥ 30% in the soft state), these tubes can be easily bent, flared, and welded without cracking.
Is oxygen-free copper safe for drinking water applications?
Absolutely. C10100 copper has natural antimicrobial properties that kill 99.9% of bacteria on contact. It is highly corrosion-resistant and completely safe for drinking water systems and medical gas pipelines.
