What materials are used for the tube?

The tube is made of high-purity Phosphorus-Deoxidized Copper (C12200) with excellent thermal conductivity and corrosion resistance.

What are the common problems and solutions for this tube?

Common issues include excessive pressure drop (solution: use larger diameter), noise/vibration (solution: reduce flow rate), and pinhole leaks (solution: install sacrificial anode).

AI-Powered supplier vetting

SummaryThe supplier is presented as a professional technical HVAC/R supplier with production lines, moulds, patents, and a complete HVAC/R product range. It reports ISO 9000 and ISO 9001 management-system certifications and states that most products hold CE, RoHS, and UL approvals. Customization is available from samples and designs, including full, minor, and flexible customization. However, the supplier does not provide 3D software design, ODM, SDK, or well-known-brand OEM services, and launched no new products in the past year. It has no overseas warehouse, showroom, agent or branch, and has not participated in offline trade shows. Service quality assurance is stated, but complaint handling and corrective-action arrangements are described only as “Others.” Financial records are referenced for 2022–2024, but no financial performance details are provided. No specific customer cases are identified.

Supplier typeThe supplier is explicitly identified as a professional technical supplier and describes a complete HVAC/R range with production lines, moulds, patents, and one-stop solutions. Its stated business scope also covers hardware, building materials, mechanical equipment, refrigeration and air-conditioning equipment, and related technical services.

CertificationsThe supplier reports ISO 9000 and ISO 9001 management-system certifications. It also states that most products are approved by CE, RoHS, and UL, although the evidence does not indicate that every product holds these approvals.

R&D capabilityThe supplier has R&D capability, patents, and states that it continues to innovate and improve technology. Conversely, it launched no new products in the past year and does not provide ODM, SDK, or 3D software design services, indicating some limitations in documented innovation-service breadth.

Production capacityThe supplier states that it owns a series of production lines and moulds and provides a complete HVAC/R product range. Its business scope includes sales of refrigeration and air-conditioning equipment and related industrial products, supporting production-related capability, although no capacity or output figures are given.

Customization capabilityThe supplier explicitly offers customization from samples and designs, as well as full, minor, and flexible customization. This supports a broad customization offering, but 3D software design is not available.

Product Q&A

Q:Does the product support custom specifications such as length, size, or color?

Yes, Nexnice offers flexible customization services. In addition to standard specifications, we support customizing tube length (up to 50 meters), outer diameter, wall thickness, as well as insulation materials (e.g., black rubber insulation tubes) and outer protective film colors to meet special project requirements.

Q:How do you ensure quality?

We follow strict QC procedures from raw materials to final inspection to ensure high quality in every step.

Q:Why choose your factory?

We are a direct manufacturer with no middleman, offering years of proven craftsmanship, a wide product range with strong R&D, and reliable, transparent lead times.

Q:How to get new product updates?

We'll promptly send you the latest posters! Just share your contact details with us.

Q:What is the minimum bending radius for installation?

Avoid bending the tube beyond its rated minimum radius to prevent copper fatigue cracking, despite its flexibility.
