About Qinhuangdao Yutian Science And Technology Co., Ltd. - Agriculture Supplier in China

Qinhuangdao Yutian Science And Technology Co., Ltd. is located in Qinhuangdao, China and currently lists nine active products in its catalogue. The catalogue includes an Automatic bellow forming machine, Bellow expansion joint, Annular hose forming machine, Helix hose forming machine, Butterfly valve, Wax Injector, C Frame Wax Injector With Double Station, Ceramic Core Injector, and Dewaxing Autoclave. These items fall under the broader agriculture machinery classification used by Chinese exporters. The product list covers both forming equipment for flexible hoses and processing units used in wax coating and dewaxing operations.

The automatic bellow forming machine and the annular and helix hose forming machines are designed for continuous production of rubber or PVC bellows and hoses, typically rated for pressures up to 1.5 MPa and capable of lengths up to 2 m per cycle. The butterfly valve is a quarter‑turn, metal‑body valve commonly supplied in DN15‑DN1000 sizes for irrigation and process flow control. Wax injectors and the ceramic core injector are used in seed or food coating lines, where injection temperatures range from 150 °C to 250 °C. The Dewaxing Autoclave provides a sealed environment for solvent removal, often operating at temperatures of 120‑180 °C and pressures of 0.5‑1 MPa.

Product Range and Specialties of Qinhuangdao Yutian Science And Technology Co., Ltd.

The supplier’s catalogue groups its equipment into three functional families: hose and bellow forming machines, valve and flow control devices, and wax/dewax processing units. In the hose‑forming segment, manufacturers typically offer machines capable of handling rubber, silicone, or PVC profiles with wall thicknesses from 1 mm to 5 mm and tensile strengths of 10‑30 MPa. Standard specifications for butterfly valves include ISO‑compliant metal bodies, ANSI B16.34 pressure classes, and face‑to‑face dimensions expressed in DN size. Wax injection systems for agricultural seed coating usually require temperature control accuracy of ±2 °C and injection pressures of 0.8‑1.2 MPa, while ceramic core injectors are designed for high‑purity waxes with particle size below 50 µm. Dewaxing autoclaves are generally built to IEC 60204 safety standards and supplied with stainless‑steel chambers sized from 200 L to 1 000 L.

Trade and Export Information - Qinhuangdao Yutian Science And Technology Co., Ltd.

China is a major exporter of agricultural processing machinery, with the majority of shipments classified under HS Chapter 84 (machinery) and Chapter 85 (electrical equipment). Buyers in Southeast Asia, the Middle East, and Africa commonly import hose‑forming equipment and coating lines to support irrigation infrastructure and seed treatment facilities. Typical import documentation includes a commercial invoice, packing list, certificate of origin, and, where required, CE or ISO 9001 conformity certificates. Containers of 20 ft or 40 ft are standard for these machines, often crated with wood and protected by moisture‑resistant wraps. Common Incoterms used are FOB Tianjin or CIF destination ports.

Sourcing from Qinhuangdao Yutian Science And Technology Co., Ltd. - Buyer Guidance

Prospective buyers should request detailed product data sheets that specify material grades (e.g., EPDM rubber, stainless‑steel 304), pressure ratings, power consumption, and dimensional drawings. Verification of ISO 9001 quality‑management certification and, where applicable, CE marking for electrical components is advisable before finalizing orders. Samples of finished hose or valve prototypes can be requested to assess compliance with industry standards such as ISO 4422 for rubber hoses or ISO 5208 for valve performance. Buyers should also confirm lead times, typical MOQ (often one unit for custom machines with optional spare‑parts kits), and warranty terms presented in the supplier’s export contract.

What types of hoses can the automatic bellow forming machine produce?

The machine can form rubber, PVC, and silicone bellows with wall thicknesses between 1 mm and 5 mm and lengths up to 2 m per cycle, meeting typical agricultural irrigation specifications.

Are the butterfly valves supplied with ISO or ANSI certifications?

The valves are manufactured to ISO‑compatible dimensions and can be supplied with ANSI B16.34 pressure‑class certification upon request. Buyers should request the relevant test reports.

What are the typical power requirements for the wax injector units?

Standard wax injectors operate on three‑phase power, ranging from 380 V to 415 V, with a rated power consumption of 5 kW to 12 kW depending on injection capacity.

How is the Dewaxing Autoclave packaged for overseas shipment?

The autoclave is shipped in a reinforced wooden crate, with internal anti‑corrosion coating and moisture‑resistant padding, fitting a 40 ft container for units up to 1 000 L capacity.

Which documents should a buyer request before purchasing the annular hose forming machine?

Buyers should obtain the product data sheet, ISO 9001 certificate, CE conformity declaration (if electrical components are included), and a test report confirming pressure rating and dimensional accuracy.

What is the usual lead time for a custom helix hose forming machine?

Lead times for custom‑designed helix machines typically range from 45 to 70 days after receipt of detailed specifications and any required tooling drawings.

Can the supplier provide sample specifications or a trial run for the ceramic core injector?

A sample injector can be supplied for performance testing; the supplier can provide a trial run report that includes temperature stability, injection pressure, and wax purity compliance.

What container size is recommended for shipping the C Frame Wax Injector With Double Station?

The double‑station injector fits comfortably in a standard 20 ft container when crated, but a 40 ft container is recommended for multiple units to optimize space and handling costs.
