STRAIGHT TUBE

Material: Copper

Characteristic

  • ① Smooth and flat surface: The surface of smooth copper straight pipes is smooth and flat, without ripples or wrinkles. This smooth surface makes them widely used in some fields that require high-precision copper pipes, such as electronics, aerospace, and medical equipment.
  • ② High purity and good conductivity: Smooth copper straight pipes usually have high purity, with copper content usually reaching over 99%, which makes them excellent in electrical and electronic fields. Smooth copper has high conductivity and can effectively reduce the loss of electrical energy during transmission.
  • ③ Excellent ductility and plasticity: Smooth copper straight pipes have good ductility and plasticity, and can be easily stretched, bent, and processed into various shapes to meet different industrial needs. This characteristic makes smooth copper straight pipes highly flexible in manufacturing various copper products.
  • ④ Corrosion resistance: Compared to ordinary copper materials, smooth copper straight pipes have better corrosion resistance and can maintain stable performance in harsh environments. This feature gives it a unique advantage in some applications that require high demands on the external environment.

Application

Due to the above characteristics, smooth copper straight pipes have been widely used in multiple fields. For example, in the field of electronics, smooth copper straight pipes are used to manufacture circuit boards and connectors; In the aerospace industry, used for manufacturing components in high-temperature environments; In the field of medical devices, used for manufacturing precision instruments and equipment.

Frequently Asked Questions

What materials are your plain and straight tubes made of?
Both our plain tubes and straight tubes are manufactured using high-quality copper. This includes specialized formulations such as Oxygen-Free Copper (OFC) for superior corrosion resistance and high-tension copper designed for high-stress applications.
What are the primary applications for plain copper tubes?
Plain copper tubes are widely utilized in the AC (air conditioning) and refrigeration industries, LNG gas installations, medical care facilities, building construction, and shipbuilding due to their high heat exchange efficiency and outstanding formability.
Why are straight copper tubes preferred in electronics and aerospace?
Straight copper tubes feature a smooth and flat surface with high purity (over 99% copper content), ensuring exceptional electrical conductivity and minimal energy loss. Their excellent ductility, plasticity, and corrosion resistance make them ideal for high-precision components like circuit boards, connectors, and aerospace parts.
What range of sizes do you offer for copper tubes?
For plain tubes, outside diameters range from 3.60mm to 28.58mm with wall thicknesses from 0.25mm to 2.00mm. For straight tubes, we offer larger dimensions, ranging from 3.60mm up to 108.00mm outside diameter, and wall thicknesses up to 3.50mm.
Are your copper tubes resistant to harsh environmental conditions?
Yes, our copper tubes exhibit excellent corrosion resistance. Specifically, our Oxygen-Free Copper (OFC) tubes and smooth straight tubes are designed to maintain stable, long-lasting performance even in demanding and harsh environmental settings.
