About Hebei Dingli Pipeline Industry Co., Ltd. - Flanges Supplier in China

China’s Hebei region hosts Hebei Dingli Pipeline Industry Co., Ltd., which currently lists five active products in its catalogue. The company categorises its offerings under Flanges and Automobile Rubber Parts, and the five items are all types of industrial hoses used for water, sand, and fuel transport. Each hose is identified with a specific HS‑code within chapter 40, reflecting its classification as a rubber hose. The catalogue includes both reinforced EPDM designs and NR/SBR blends, indicating a focus on durability and pressure resistance.

The product list comprises a Tank truck hose (no HS code disclosed), a Water hose (HS 4009.21) made from black synthetic EPDM rubber with rubber reinforcement, a Sand suction hose (HS 4009.21) using a synthetic NR/SBR blend reinforced with polyester tire cord, an EPDM lay‑flat water discharge hose (HS 4009.11) featuring EPDM rubber cover and high‑tensile textile cord, and a Contractors water discharge hose (HS 4009.22) constructed from an EPDM/SBR blend with synthetic yarn reinforcement. These entries show the supplier’s emphasis on reinforced rubber compounds suitable for high‑stress discharge applications.

Product Range and Specialties of Hebei Dingli Pipeline Industry Co., Ltd.

The catalogue’s five hoses cover common segments of the rubber‑hose market. EPDM‑based hoses such as the lay‑flat water discharge model are typically rated to 1.2 MPa (180 psi) and meet ISO 4421 specifications for water‑carrying hoses, while NR/SBR blends used in the sand suction hose are favored for abrasion resistance and often conform to ASTM D2000 class C‑R. Reinforcement materials - textile cords, polyester tire cord, or synthetic yarn - are standard methods to achieve burst pressures of 3 - 5 MPa depending on hose diameter, which in the industry ranges from 16 mm to 200 mm inner diameter. Buyers usually request data on tensile strength (MPa), elongation at break (%), and temperature limits (‑30 °C to +80 °C) to match application needs.

Chinese hose manufacturers also produce flanged fittings and automobile rubber components, although those items are not itemised in the current catalogue. In the broader market, flanges are commonly supplied in accordance with ISO 7005‑1 (steel) or ASME B16.5 (cast iron) standards, while automobile rubber parts adhere to SAE J2032 material specifications. This context helps buyers understand the typical quality grades that complement the listed hose products.

Trade and Export Information - Hebei Dingli Pipeline Industry Co., Ltd.

China ranks among the world’s largest exporters of rubber hoses, with HS‑code 4009.11, 4009.21 and 4009.22 covering water, fuel and industrial suction hoses respectively. Importers in Southeast Asia, the Middle East, Africa and parts of Europe frequently source these products for irrigation, construction, mining and municipal water distribution. Buyers normally require certificates such as ISO 9001 for quality management, ISO 14001 for environmental compliance, and CE marking when the hoses are destined for the EU market. Shipping is usually performed in 20‑ft or 40‑ft containers, with hoses coiled on pallets or in bulk, and Incoterms like FOB Tianjin or CIF Shanghai are common. Regulatory checks often involve verification of the HS code against the material description, compliance with REACH (EU) or TSCA (US) for hazardous substances, and inspection of reinforcement integrity under ASTM D1599 burst‑pressure testing. Chinese exporters typically provide a commercial invoice, packing list, certificate of origin and, upon request, a third‑party lab test report to satisfy customs and buyer due‑diligence.

Sourcing from Hebei Dingli Pipeline Industry Co., Ltd. - Buyer Guidance

When evaluating Hebei Dingli’s hoses, request a material data sheet that details the rubber compound, reinforcement type, and exact pressure rating. Ask for test reports that cover burst pressure (ASTM D1599), tensile strength (ISO 1432) and ageing resistance, as these documents confirm compliance with the specifications buyers normally require. Verify that the HS code on the commercial invoice matches the product description and that the supplier can provide certificates such as ISO 9001 or a CE declaration if the destination market mandates them. Typical minimum order quantities for reinforced rubber hoses range from 500 m to 1 000 m per size, with lead times of 4 - 6 weeks after order confirmation. Samples of 10 m coiled sections are standard for performance evaluation, and buyers should confirm packaging (e.g., double‑wall cardboard, moisture‑proof film) and labeling requirements before finalising the order.

What hose types are listed in the catalogue?

The catalogue lists a Tank truck hose, a Water hose (HS 4009.21, black EPDM), a Sand suction hose (HS 4009.21, NR/SBR blend), an EPDM lay‑flat water discharge hose (HS 4009.11) and a Contractors water discharge hose (HS 4009.22, EPDM/SBR blend).

Which HS codes apply to the listed hoses?

Water hose and Sand suction hose use HS 4009.21, the EPDM lay‑flat water discharge hose uses HS 4009.11, and the Contractors water discharge hose uses HS 4009.22. The Tank truck hose does not have an HS code provided in the facts.

What materials are used for reinforcement in the hoses?

Reinforcement varies: the Water hose uses rubber reinforcement, the Sand suction hose incorporates polyester tire cord, the EPDM lay‑flat hose employs high‑tensile textile cord, and the Contractors hose uses synthetic yarn reinforcement.

Which certifications should I ask the supplier to provide?

Buyers typically request ISO 9001 quality‑management certification, ISO 14001 environmental certification, and, where required, CE marking or REACH compliance for EU destinations. These are not listed as held by the supplier, so they should be confirmed.

What is a common minimum order quantity for these hoses?

In the rubber‑hose market, MOQ commonly starts at 500 meters per hose size, though exact quantities depend on diameter and reinforcement type.

How are the hoses usually packaged for export?

Export packaging generally involves coiling the hoses on pallets, wrapping them in moisture‑resistant film, and placing them in sealed cardboard boxes or bulk crates suitable for 20‑ft or 40‑ft containers.

What lead time can I expect for an order?

Lead times for reinforced rubber hoses from Chinese manufacturers typically range from four to six weeks after order confirmation, subject to material availability and size specifications.

How can I obtain a sample before placing a full order?

Request a 10‑meter coiled sample of the specific hose type; suppliers usually provide such samples for performance testing and dimensional verification before a larger purchase.
