Copper Tube Coil NUNGWON METAL Type K ASTM B88 Soft 34.75in x 2.5in

Description

Product Overview

The NUNGWON Type K soft copper tube coil is a premium industrial component engineered to meet the rigorous ASTM B88 specification for seamless copper tubing. Manufactured by NUNGWON METAL IND, a trusted name in metal fabrication, this coil offers a generous 34.75‑inch length and a 2.5‑inch width, providing ample material for a wide range of applications. The coil’s dimensions—34.75 x 2.5 x 0.1 inches—are precisely controlled to ensure consistency across each batch, while the overall weight of 48 pounds reflects the solid, high‑density copper construction.

Purity and conductivity are at the heart of this product’s performance. The copper used in the coil is refined to a high degree of purity, delivering excellent electrical and thermal conductivity that surpasses many competing alloys. This ensures that the tube coil can efficiently transfer heat, resist corrosion, and maintain structural integrity even under demanding operational conditions. The soft nature of the copper allows for easy bending and shaping, making it ideal for custom installations where flexibility is essential.

The manufacturing process combines advanced extrusion techniques with meticulous quality control. Each coil is formed using state‑of‑the‑art equipment that guarantees uniform wall thickness and smooth interior surfaces, reducing friction losses in fluid flow applications. After extrusion, the coil undergoes a series of annealing and cleaning steps to relieve internal stresses and remove any surface contaminants, resulting in a product that is ready for immediate use without additional preparation.

Packaging is designed for both protection and convenience. The coil is coiled tightly yet carefully to prevent deformation, and it is shipped in a sturdy, moisture‑resistant container that safeguards the copper from environmental exposure during transit. Clear labeling includes the model number C122KSC10060, color designation (copper), and key specifications, enabling quick identification and inventory management for distributors and end users alike.

Compliance with industry standards extends beyond ASTM B88. The coil also aligns with ISO 9001 quality management principles, ensuring that each unit meets stringent performance criteria. Its versatility makes it suitable for a broad spectrum of sectors, including HVAC, plumbing, refrigeration, and specialized heat‑exchange systems where reliable copper tubing is a critical component.

Usage

In industrial piping systems, the NUNGWON Type K copper tube coil serves as a flexible conduit for water, steam, and refrigerants. Its high thermal conductivity enables efficient heat transfer, making it an excellent choice for heat exchangers, condensers, and boiler feed lines. The soft copper construction allows installers to bend the coil around obstacles and fit it into tight spaces without compromising flow characteristics.

For HVAC applications, the coil’s durability and resistance to corrosion ensure long‑term reliability in air‑conditioning units and ventilation ducts. Technicians can shape the tube to match complex ductwork layouts, reducing the need for additional fittings and minimizing pressure drops. The copper’s antimicrobial properties also contribute to improved indoor air quality by inhibiting bacterial growth within the system.

Custom fabrication projects benefit from the coil’s ease of handling. Fabricators can cut the tube to precise lengths, create custom bends, and integrate the material into prototypes or specialized equipment. Because the copper is soft yet strong, it tolerates repeated forming operations without cracking, supporting iterative design processes in research and development environments.

In refrigeration and cooling systems, the coil’s ability to conduct heat quickly enhances the efficiency of evaporators and condensers. The seamless interior surface reduces turbulence, allowing refrigerant to flow smoothly and improving overall system performance. Installers appreciate the coil’s consistent dimensions, which simplify the selection of compatible fittings and reduce installation time.

FAQ

What does Type K mean for copper tubing?

Type K refers to a classification of copper tube that is soft, annealed, and suitable for a wide range of applications. It offers excellent flexibility, making it easy to bend and shape without cracking, while still providing high thermal and electrical conductivity.

How should the coil be installed in a piping system?

Begin by measuring the required length and cutting the tube with a tube cutter to ensure a clean edge. Use a tube bender or hand‑bending tools to achieve the desired curvature, then connect the ends with compatible fittings. Always follow local codes and verify that the installation maintains proper clearance and support.

Can this copper coil be used with standard fittings?

Yes, the coil’s dimensions conform to standard copper tube sizes, allowing it to be paired with commonly available fittings such as compression, solder, and flare connectors. Verify the fitting size matches the tube’s outer diameter to ensure a secure, leak‑free connection.

Is the copper material suitable for high‑temperature applications?

The high‑purity copper used in this coil retains its mechanical strength and conductivity at elevated temperatures, making it appropriate for steam lines, boiler feed systems, and other high‑heat environments. However, always consult the specific temperature ratings for your application to ensure safety and performance.
