Copper Tube - Detailed Description

Material:
Made from high-purity copper, typically 99.9% pure. The most common grades are C12200 (phosphorus-deoxidized, high residual phosphorus) and C11000 (electrolytic tough pitch copper).

Types:

Type K Thickest walls, used for underground or heavy-duty applications. Type L Medium thickness, ideal for residential water lines and HVAC systems. Type M Thinner walls, suitable for low-pressure residential applications. DWV (Drain, Waste, Vent) Thin-walled, used for drainage systems.

Sizes:

Nominal Sizes: Ranges from 1/4 inch to 8 inches in diameter. Outer Diameter (OD): Common OD sizes include 6mm, 12mm, 15mm, 22mm, and 28mm. Wall Thickness: Varies by type; thicker for Type K, thinner for Type M.

Length:

Supplied in straight lengths (usually 10, 12, or 20 feet) or in coils (up to 100 feet). Coiled tubes are flexible and easier to install in tight spaces.

Finishes:

Plain (bare): Natural copper finish. Pre-insulated: Covered with foam insulation for HVAC applications. Polished: For decorative or aesthetic uses.

Properties:

Corrosion-resistant: Suitable for both indoor and outdoor use. High thermal conductivity: Excellent for heat exchange in HVAC systems. Durable and flexible: Can withstand high pressures and temperatures. Antimicrobial: Naturally inhibits bacterial growth, ideal for potable water systems.

Applications:

Plumbing: Hot and cold water supply lines. HVAC: Refrigerant lines, air conditioning, and heating systems. Gas Lines: Safe for natural gas and propane distribution. Medical Gas Systems: Due to its antimicrobial properties. Industrial: Heat exchangers, solar panels, and condensers.

Standards & Certifications:

Conforms to ASTM B88, EN 1057, or BS 2871 standards depending on the region. Certified for potable water use and often lead-free.

Packaging:

Bundled in plastic wrap or boxed for protection. Coiled tubing often comes in protective spools for easy transport.
