Import Flow Couplings — Buy in Bulk from Supplier in China

Tianjin Huachang Xingye Technology Co., Ltd. manufactures heavy‑wall flow couplings intended for tubing strings in demanding industrial environments. The couplings are built from high‑grade steel and are engineered to minimise pressure spikes and vibration, thereby preserving the integrity of the line. The supplier notes that the products are available in a range of sizes and configurations to suit specific tubing dimensions, and that they feature precision‑engineered, leak‑proof connections. These attributes make the couplings suitable for continuous operation in oil and gas, hydraulic and water‑treatment installations.

The material used is a high‑grade alloy steel that typically conforms to ASTM A105 or equivalent standards, providing good tensile strength and corrosion resistance. Typical pressure ratings for similar heavy‑wall couplings are up to 200 bar, and they can operate safely from - 20 °C to 150 °C, which covers most field conditions. Standard dimensions for the couplings fall within DN 25 to DN 200 mm, with a typical weight of around 2 kg per unit. The design incorporates a precision‑machined sealing surface that reduces leakage risk and shortens installation time, often allowing tool‑free assembly.

The primary buyers are operators of oil‑field production strings, water‑treatment facilities and hydraulic system integrators who require reliable, high‑performance connections. Tianjin Huachang Xingye lists ISO and CE certifications as part of its quality assurance, although the exact certification numbers are not disclosed. The listing does not provide MOQ, price or lead‑time, so prospective importers should request those details directly. Trade terms, packaging and shipping arrangements are negotiated individually with the supplier.

Tianjin Huachang Xingye Technology Co., Ltd. is based at No.890412 Chenglin Road, Hedong 3000, Tianjin, China. The company is listed with a harbor trust tier and a zero‑percent response rate, indicating that initial contact may require follow‑up before a detailed reply is received. Their public profile focuses on the design and manufacture of flow couplings for high‑pressure and vibration‑prone applications.

The supplier highlights that its couplings are produced under stringent quality‑control processes and that they carry ISO and CE certifications, though specific certificate numbers are not provided. No further corporate details such as annual turnover, employee count or client references are disclosed, so buyers should request additional documentation to confirm compliance and capacity.
