Products Description

Our Advantages

1. Strong Corrosion Resistance

Our copper alloy pipes are manufactured using a cold drawing process, eliminating corrosion weak points, and are further treated with pickling and passivation to enhance corrosion resistance.
Our pipes undergo rigorous chemical composition testing to ensure the alloy composition meets ASTM B466 standards.

2. High Thermal Conductivity

Our pipes feature a cold-drawn and polished surface, uniform wall thickness, and a smooth inner surface, ensuring efficient heat transfer.
Our pipes have a thermal conductivity of up to 29 W/m·K, making them ideal for condensers, evaporators, and industrial heat exchangers.

3. Excellent Machinability

Our copper alloy pipe can be bent, expanded, or welded without cracking, allowing for easy installation in condensers, U-tubes, or complex piping layouts.
Our pipes are suitable for TIG, MIG, and resistance welding methods, and undergo non-destructive testing and hydrostatic testing to ensure welds can withstand pressure, vibration, and thermal cycling.

4. Customization Services

TORICH offers customized sizing services to ensure a perfect fit with tube sheets, reducing on-site processing.
U-bending/multi-bend processing, flat end, bevel end treatment, and inner surface polishing are available.

5. Quality Control

TORICH maintains a strict and traceable quality control system from raw material selection to final delivery, ensuring compliance with ASTM B466 standards.
TORICH provides dimensional inspection reports, factory test certificates, and third-party inspections from SGS and TUV, guaranteeing a long service life in condensers and heat exchangers.
