Megaatube Refrigeration & Air Conditioning Copper Pipe | ASTM B280 & JIS H3300

High-Performance Copper Pipe for HVAC & Refrigeration

Megaatube brand offers a comprehensive range of premium copper pipe specifically engineered for refrigeration and air conditioning systems. Whether you require hard-drawn straight lengths or soft annealed coils, our copper piping is manufactured to comply with the most stringent international standards, including ASTM B280 and JIS H3300.

Our copper pipe is designed for maximum durability and thermal conductivity, making it the ideal choice for residential, commercial, and industrial cooling applications.

Technical Specifications & Standards

We ensure every copper pipe meets precise chemical and mechanical requirements for safety and performance:

• Standard Compliance: ASTM B280 (Alloy C12200) and JIS H3300 (Alloy C1220).

• High Purity: Phosphorus Deoxidized Copper with over 99.9% Cu + Ag composition.

• Temper Options: Available in Soft Annealed (O60) for coils and Hard Drawn (H58) for straight lengths.

• Precision Integrity: 100% electronically tested using the Eddy Current method (ASTM E 243) to ensure zero defects.

Enhanced Pressure Rating for R410A Systems

Modern cooling systems require stronger materials. Our copper pipe range includes increased wall thicknesses specifically designed to handle the 60% higher operating pressures of R410A refrigerant compared to older R22 systems.

Installation Note: For high-pressure refrigerant applications, we recommend using 15% silver solder during the brazing process to ensure a secure, leak-proof joint
