Straight Length Copper Tubes

-- Steady & Reliable Manufacturer --

The Foundation of Industrial Piping Systems

Straight length copper tubes are the structural backbone of high-integrity fluid and gas distribution systems. Unlike coiled tubing, which is prioritized for flexibility and long continuous runs, straight lengths are engineered for rigidity, aesthetic precision, and high-pressure performance in exposed or structural installations. Manufactured typically in "Hard" (H58) or "Half-Hard" (H55) tempers, these tubes maintain their linear integrity over long spans, making them the preferred choice for commercial plumbing, medical gas systems, and industrial processing plants. Our manufacturing process involves precision drawing and rigorous straightening stages to ensure that every pipe meets exact dimensional tolerances and lacks any bowing or surface irregularities. This is critical for installations where the piping is visible or must pass through tight, pre-drilled structural supports.

At Zhejiang Jingliang, we understand that industrial projects demand more than just a pipe; they demand a component that facilitates easy installation and long-term reliability. Our straight lengths are produced from high-purity C12200 phosphorus-deoxidized copper, which provides excellent weldability and brazing characteristics. This is vital because straight length systems often involve numerous joints, elbows, and tees. The uniformity of our wall thickness ensures that when heat is applied during the brazing process, it distributes evenly, resulting in leak-proof connections that can withstand decades of thermal expansion and contraction. Furthermore, we offer specialized cleaning services for these pipes, including degreasing for oxygen service or high-purity lab environments. Whether you are building a central cooling plant for a skyscraper or a complex chemical delivery line, our straight length copper tubes provide the professional-grade finish and structural strength required by modern engineering standards.

Broad Spectrum Industrial Applications

Straight length copper tubes are ubiquitous in large-scale construction and industrial engineering. One of their most prominent roles is in commercial plumbing and potable water distribution, where the rigid nature of the pipe allows for clean, organized layouts in utility rooms and riser shafts. In the healthcare sector, these pipes are the gold standard for medical gas pipeline systems (MGPS), delivering life-saving oxygen and vacuum services. They are also extensively used in fire sprinkler systems where high heat resistance is required. In the industrial sector, straight lengths serve as connection lines for large chillers, steam heating systems, and compressed air networks. Their ability to handle high pressures and temperatures makes them suitable for conveying hydraulic fluids and lubricating oils in heavy machinery. Finally, they are a staple in the HVAC industry for the main refrigerant headers in VRF (Variable Refrigerant Flow) systems, where multiple indoor units connect to a single large-diameter straight-run manifold.

Advantages of Rigid Straight Tubing

The primary advantage of straight length copper tubing is its superior mechanical strength and aesthetic appeal. When installed, these pipes do not sag or warp, requiring fewer support brackets compared to flexible tubing, which reduces both material and labor costs in large-scale projects. The hard-drawn temper provides a much higher burst pressure rating, allowing for thinner walls in high-pressure applications—a significant cost saving for the buyer. Additionally, the internal bore of our straight lengths is exceptionally smooth, which minimizes friction loss and noise in high-velocity water or gas systems. Our strict quality control ensures that the ends of each pipe are perfectly square and burr-free, facilitating faster and more reliable connections with press-fit or solder fittings. By choosing our straight lengths, you also benefit from our precision straightening technology, which eliminates the "memory" effect found in uncoiled tubes, ensuring that your installation looks as professional as it performs.

Packaging and Global Distribution

Logistics for straight length pipes require specialized handling to prevent bending during transit. We typically bundle these pipes in hexagonal crates or heavy-duty wooden boxes, depending on the wall thickness and length. For 5.8m and 6m lengths, we optimize packing for 20ft or 40ft containers to ensure minimal movement and zero damage. We offer flexible payment terms including T/T (Telegraphic Transfer) and L/C (Letter of Credit) for large-scale infrastructure orders. As a factory with direct export licenses, we handle all customs documentation, including Mill Test Certificates and Certificates of Origin. Our proximity to Ningbo port allows for rapid dispatch. We also offer specialized "half-bundle" quantities for smaller distributors who need to maintain a wide variety of sizes without over-investing in inventory. Each bundle is clearly tagged with the material grade, size, and batch number for full traceability.

  • Q: What is the benefit of the "Half-Hard" temper?
  • A: Half-hard (H55) temper provides a middle ground; it is rigid enough to stay straight over long runs but retains enough ductility to allow for slight offsets or machine bending without the need for annealing.
  • Q: Can you provide straight lengths for medical oxygen use?
  • A: Yes, our straight lengths can be degreased and capped according to ASTM B819 or EN 13348 standards, specifically for medical gas applications.
  • Q: Are custom lengths available?
  • A: Absolutely. While 3m and 6m are standard, we can cut to any specific length (e.g., 5.8m for container optimization) to suit your project requirements.
