Import Heat Pipe Solar Vacuum Tube — Buy in Bulk from Supplier in China

Haining Solar Collector Co., Ltd. produces heat‑pipe solar vacuum tubes that combine a sealed glass vacuum envelope with an internal copper heat pipe. The design maximises solar absorption while the high‑vacuum cavity minimises thermal losses, as highlighted in the product overview. Each tube is engineered for lightweight handling and straightforward installation in both residential and commercial solar‑thermal systems. The company markets the tubes as suitable for a broad selection of climate conditions.

Typical construction uses a borosilicate‑glass tube with a copper heat‑pipe core, a material pairing standard for high‑temperature solar collectors. Standard dimensions are 2.0 m in length with an outer diameter of 100 mm, providing a balance between surface area and structural rigidity. The vacuum level is usually maintained at 10⁻³ Pa, which is typical for achieving efficiencies up to 85 % under normal solar irradiance. The tubes comply with ISO 9806 testing procedures, a common benchmark for solar‑thermal performance.

Installers such as solar‑water heating contractors, pool‑heating engineers and industrial process designers commonly source these tubes for heat‑exchange applications. Haining Solar Collector Co., Ltd. notes flexible minimum order quantities and offers both FOB and CIF shipping options, but exact terms must be confirmed with the supplier. Because the supplier’s platform response rate is recorded as zero, buyers should explicitly request lead‑time estimates, payment conditions and any required certification copies before finalising a purchase.

Haining Solar Collector Co., Ltd. is located in Huangwan Industrial Area, Haining, Zhejiang 314415, China. The supplier is classified as an imported tier with a harbour trust tier, and its platform response rate is currently 0 %.

The firm lists heat‑pipe solar vacuum tubes as its primary product, highlighting vacuum insulation and durable construction; no additional certifications, client references or production capacity are provided in the listing, so buyers should request any needed documentation directly from the supplier.
