High-Purity Materials and Precise Craftsmanship
Air conditioning copper tubes are predominantly made from materials such as T2 pure copper and TP2 phosphor-deoxidized copper (copper content ≥99.9%), offering excellent ductility and compressive strength (e.g., R410A copper tubes can withstand pressures of 45–50KG). Shandong Fengmai Metal Materials Co., Ltd. provides customized services, offering copper tube specifications (outer diameter: 4–19.05mm, wall thickness: 0.3–1.5mm) tailored to different refrigerants (R22/R32/R410A) and system pressure requirements.
Efficient Heat Conduction and Energy-Saving Design
Copper’s thermal conductivity (400W/(m·K)) far exceeds materials like stainless steel and aluminum. Combined with internal threading or thin-walled processes, heat transfer efficiency is increased by over 30%. Fengmai also supplies high-precision seamless steel tubes (e.g., alloy steel tubes for petroleum cracking, high-pressure boiler tubes) to meet the auxiliary component needs of complex air conditioning system structures.
Corrosion Resistance and Long Lifespan
The oxide film on copper tubes resists corrosion from refrigerant decomposition products (e.g., acidic substances) and humid environments, with a service life of over 15 years. For extreme environments, Fengmai offers stainless steel tubes (304/316L materials) with excellent chloride ion corrosion resistance, suitable for protecting outdoor unit pipelines in coastal or chemical industry scenarios.
Extended Services of Fengmai Metal Materials
Diversified Pipe Supply
In addition to air conditioning copper tubes, the company specializes in:
- Alloy steel tubes (15CrMoG, P91)
- Stainless steel tubes (seamless/welded)
- Galvanized steel tubes
These cover industries such as petrochemicals, power equipment, and machinery manufacturing, supporting non-standard customization (outer diameter: 6–630mm, wall thickness: 1–50mm).
High-Standard Production and Testing
Products comply with standards such as GB (Chinese National Standard), ASTM (American Standard), and DIN (German Standard), and undergo inspection processes like eddy current flaw detection and hydrostatic testing to ensure pipeline sealing and pressure-bearing capacity.
Industry Scenario Adaptation Solutions
- Seamless steel tubes: For high-pressure steam pipelines and hydraulic systems
- Stainless steel tubes: For food-grade sanitary pipelines and corrosion-resistant structural components
- Alloy steel tubes: For high-temperature boilers and geological drilling equipment
Selection Recommendations
As a core component of refrigeration systems, air conditioning copper tubes should 优先匹配冷媒类型与设备匹数 (be prioritarily matched to refrigerant types and equipment horsepower, e.g., Φ6.35–9.52mm copper tubes for 1HP air conditioners). For complex working conditions (high pressure, corrosive environments), combining with Fengmai’s stainless steel or alloy steel tubes as auxiliary support pipelines balances cost and reliability.
For product catalogs or technical parameters, contact Fengmai for one-stop procurement solutions for seamless steel tubes, stainless steel tubes, and copper tubes (supporting sample delivery and OEM services).
