About Hebei The Earth Pipe Industry Co, Ltd - Agriculture Supplier in China

China‑based Hebei The Earth Pipe Industry Co, Ltd lists eight active products focused on concrete pump and related equipment. The catalogue includes pump truck fittings rubber sponge cleaning balls, an export‑special pump truck hose, DN125 concrete pump pipe flange, wear‑resisting concrete pump pipe forging flange, hose for piling machine, concrete pump hinge bent pipe, lithium grease for concrete pump spare parts, and a lithium‑based grease for concrete pump.

The supplier classifies its activity under the Agriculture top category, though the product set serves the construction and infrastructure sectors that utilise concrete pumping systems. Each item is identified by its functional description rather than a model number, and the range spans metal flanges, reinforced hoses, and specialty lubricants designed for high‑pressure pump components.

Product Range and Specialties of Hebei The Earth Pipe Industry Co, Ltd

The eight listed items cover three material groups: forged or cast steel flanges, reinforced rubber hoses, and lithium‑based lubricating greases. In the concrete pump market, DN125 pipe flanges typically conform to pressure classes PN10‑PN16 and are fabricated from ductile iron or forged steel to meet DIN 2441 or ISO 7005 standards. Reinforced hoses for pump trucks and piling machines are commonly built with rubber inner liners and steel braid, rated up to 30 bar, and comply with EN 805 or ISO 4422 specifications. Lithium‑based greases for pump spare parts are usually graded NLGI 2, with an ISO VG 100 base oil, providing thermal stability up to 120 °C and water resistance suitable for hydraulic seals.

Buyers of these components often request material certificates indicating compliance with ASTM A36 for steel, ISO 9001 quality management, and MSDS for greases. The cleaning balls are typically made from closed‑cell polyurethane foam, sized 20‑30 mm, and used to remove residue from pump interiors without damaging surfaces.

Trade and Export Information - Hebei The Earth Pipe Industry Co, Ltd

China remains a major exporter of concrete pump accessories, shipping primarily to construction‑intensive regions such as Southeast Asia, the Middle East, Africa, and Eastern Europe. Export shipments are usually consolidated in 20‑foot containers, with flanges and hoses packed in wooden crates to prevent deformation, while greases are sealed in metal drums of 200 L capacity. Importers commonly require HS chapters 73 (iron and steel products) for flanges, chapter 40 for rubber hoses, and chapter 38 for lubricating greases, and they may request conformity to CE marking or ISO 9001 as part of the due‑diligence process.

While the supplier’s target markets are not listed, typical buyers include concrete pump manufacturers, equipment distributors, and large construction firms that need spare parts for high‑pressure pumping operations. Regulatory checks often involve verifying that hydraulic hoses meet EN 853 pressure‑test standards and that greases comply with ASTM D445 viscosity specifications before clearance at customs.

Sourcing from Hebei The Earth Pipe Industry Co, Ltd - Buyer Guidance

When sourcing from this supplier, request a material test report for each steel flange, confirming grade, tensile strength, and pressure rating. For hoses, ask for an EN 805 compliance certificate and a batch test report showing burst pressure at the specified rating. Grease shipments should be accompanied by an MSDS and a laboratory analysis confirming NLGI grade, ISO VG viscosity, and drop‑point temperature.

It is advisable to obtain a sample of the cleaning balls to verify foam density and resistance to abrasion before placing a bulk order. Verify that the supplier can provide ISO 9001 certification or equivalent quality‑management documentation, as this is a standard requirement for construction‑equipment components entering regulated markets.

What types of concrete pump pipe flanges does Hebei The Earth Pipe Industry Co, Ltd offer?

The catalogue lists a DN125 concrete pump pipe flange and a wear‑resisting forged flange, both intended for high‑pressure pump lines and typically fabricated from ductile iron or forged steel to meet pressure classes up to PN16.

Are the pump truck hoses reinforced for high pressure?

The export special pump truck hose and the hose for piling machine are described as reinforced, which in industry terms means a rubber inner layer with steel braid, rated up to 30 bar and complying with EN 805 standards.

What specifications apply to the lithium‑based greases?

Both lithium greases are lithium‑based, commonly graded NLGI 2 with an ISO VG 100 base oil, offering thermal stability to about 120 °C and water resistance suitable for concrete pump hydraulic seals.

What packaging format is used for the greases?

Lithium greases for concrete pumps are typically shipped in metal drums of 200 L, sealed to prevent contamination and to meet transport regulations for hazardous substances.

Which documents should a buyer request before ordering?

Buyers should request material certificates for flanges, EN 805 compliance for hoses, an MSDS and viscosity test report for greases, and any applicable ISO 9001 quality‑management certification.

What are the typical lead times for these concrete pump components?

Lead times for forged flanges and reinforced hoses generally range from 4 to 8 weeks depending on production scheduling, while greases and cleaning balls can be dispatched within 2 weeks after order confirmation.

Which HS chapters are relevant for customs clearance of these items?

Flanges fall under HS chapter 73 (iron and steel products), hoses under chapter 40 (rubber and plastics), and lubricating greases under chapter 38 (organic chemicals).

Can the supplier provide samples of the cleaning balls?

Yes, the supplier lists pump truck fittings rubber sponge cleaning balls and typically provides a small sample pack for performance testing before a bulk purchase.
