About Hunan Steel Pipe - Agriculture Supplier in China

China‑based Hunan Steel Pipe lists seven distinct steel pipe products in its catalogue. The active product count of 7 includes Reducer, Square tube, ERW, Rectangle tube, Elbow, Seamless steel pipe and Tee. Each item falls under the broader steel pipe and tube families that are normally coded under HS chapters 7304 (welded tubes) and 7305 (seamless tubes). The supplier’s top‑level market classification is Agriculture, indicating that the pipe components are often used in irrigation, water conveyance and other farm‑related infrastructure. The product list reflects a focus on both standard shapes (square, rectangle, tee) and specialised fittings (reducer, elbow) for pipeline construction.

Product Range and Specialties of Hunan Steel Pipe

The catalogue offers ERW (Electric Resistance Welded) pipe, which in the industry is commonly produced to ASTM A53 or API 5L specifications, with diameters ranging from 15 mm to 600 mm and wall thicknesses from 2 mm to 20 mm. Square and rectangle tubes are typically supplied in structural grades such as S355 or Q235, with dimensions measured in millimetres and standard lengths of 6 m. Reducers and elbows are fabricated to match the same pressure class as the base pipe, often rated to PN10‑PN25 (≈10‑25 bar) and finished with bevelled or welded ends. Seamless steel pipe is the high‑pressure variant, frequently conforming to API 5L X42‑X70 grades for oil‑and‑gas transport. Tee fittings are used for branch connections and are usually offered in the same dimensional series as the base pipe, with bolt‑hole patterns that match standard flange standards. Buyers can expect typical packaging in bundled bundles, shrink‑wrapped on pallets, suitable for 20‑ft or 40‑ft container loading.

Trade and Export Information - Hunan Steel Pipe

China is one of the world’s largest exporters of steel pipe products, and exporters from the country generally ship under HS codes 7304 (welded tubes and pipes) and 7305 (seamless tubes and pipes). Major import regions for Chinese steel pipe include the Middle East, Africa, Southeast Asia and parts of Europe, where the material is used for construction, oil‑and‑gas pipelines, water‑distribution and agricultural irrigation systems. Buyers usually request ISO 9001 quality management certification, CE marking for EU markets, and API product certification for oil‑field applications. Typical logistics involve loading bundled pipe sections onto 20‑ft containers (≈12 tonnes) or 40‑ft containers (≈24 tonnes), with FOB or CIF incoterms being the most common terms. Export controls in China require compliance with customs valuation, anti‑dumping duties where applicable, and proper documentation such as commercial invoices, packing lists and certificates of origin.

Sourcing from Hunan Steel Pipe - Buyer Guidance

When sourcing steel pipe from Hunan Steel Pipe, buyers should ask for mill test reports (MTR) that confirm chemical composition and mechanical properties against the relevant ASTM, API or EN standards. Request material certificates that specify the grade (e.g., API 5L X65, ASTM A53) and verify that dimensions, wall thickness and pressure ratings match the purchase specification. It is advisable to obtain a sample of a representative tube or fitting to check fit‑up, threading or welding preparation before confirming a full order. Verify that the supplier can provide the required certifications (ISO 9001, CE, API) and that packaging meets the buyer’s logistics plan, typically pallets with shrink‑wrap and protective banding. Confirm the minimum order quantity, which for pipe products is often expressed in metric tonnes per size, and allow a lead time of four to six weeks for production and inspection.
