About Huadong Screen Company - Wire Mesh Supplier in China

Huadong Screen Company is based in China and lists ten distinct products across its catalogue. The catalogue combines items classified under Wire Mesh and Stainless Steel Pipes & Pipe Fittings, covering well screen pipes, petroleum casing pipes, and specialty screens such as Johnson and Bridge slot screens. Two items include explicit HS codes: Johnson screens (HS 7306.29) made from stainless steel 304/316L V‑wire with a base pipe, and Bridge slot screens (HS 7314.29) fabricated from stainless steel 316. The remaining eight entries describe high‑quality oil, water, geothermal, and multilayer well screen pipes, as well as galvanized and wedge‑wire wrap variants, all typical of the wire‑mesh‑based screening products used in oil‑field and water‑well applications. The supplier’s tier is listed as imported with a harbor trust rating, indicating participation in international trade channels.

Product Range and Specialties of Huadong Screen Company

The product list includes stainless‑steel well screen pipes, petroleum casing pipes, oil and water well screens, multilayer and geothermal screen pipes, galvanized and wedge‑wire wrap screen pipes, plus the Johnson and Bridge slot screen families. In the wire‑mesh sector, buyers commonly encounter mesh grades of 304 and 316 stainless steel, mesh openings ranging from 2 mm to 20 mm, and wire diameters between 0.3 mm and 2.0 mm, all conforming to ASTM A193 or A194 specifications. For stainless‑steel pipe and fitting products, industry standards such as ASTM A252, API 5L, and EN 10217 define pressure ratings (often up to 150 bar), diameter ranges (½‑inch to 12‑inch), and corrosion‑resistance requirements. Typical export packs involve 20‑ft or 40‑ft containers with pipes bundled in wooden crates, and mesh screens wrapped in moisture‑resistant film to preserve dimensional stability.

Trade and Export Information - Huadong Screen Company

China is a leading exporter of stainless‑steel wire mesh and oil‑field pipe products, supplying markets in the Middle East, Africa, Southeast Asia, and Latin America. The HS 7306 and HS 7314 chapters cover metal fittings and other stainless‑steel articles, which are routinely subject to customs inspection for compliance with material composition and anti‑dumping regulations. Buyers usually request mill test reports, CE marking, and ISO 9001 certification to confirm conformity with international quality systems. Export logistics often employ FOB Shanghai or Ningbo ports, with containers loaded under standard Incoterms such as CIF or DAP, and cargo is typically secured with steel strapping and palletized for handling. Chinese manufacturers of these products frequently participate in trade fairs like CITECO and follow the China Compulsory Certification (CCC) framework for certain mechanical components.

Sourcing from Huadong Screen Company - Buyer Guidance

When sourcing from Huadong Screen Company, buyers should obtain a mill test report that details the stainless‑steel grade, tensile strength, and corrosion‑resistance data for each screen or pipe. Requesting a third‑party inspection certificate (e.g., SGS or BV) for dimensions, mesh opening tolerance, and pressure‑test results helps verify product compliance before shipment. Verify that the supplier can provide certification copies such as ISO 9001 or CE, and confirm packaging details - typically wooden crates for pipes and moisture‑proof film for mesh - to ensure safe transit. Clarify lead times, minimum order quantities (often expressed in metric tonnes or unit counts per container), and preferred Incoterms to align with your logistics plan.

What stainless‑steel grades are used in Huadong Screen Company's wire‑mesh products?

The catalogue specifies stainless‑steel 304/316L for Johnson screens and stainless‑steel 316 for Bridge slot screens; other screen types are typically produced from comparable grades within the 304‑316 range.

Which HS codes apply to the Johnson and Bridge slot screens?

Johnson screens are classified under HS 7306.29, while Bridge slot screens fall under HS 7314.29, both within the stainless‑steel articles chapter.

What documentation should a buyer request before purchasing well screen pipes?

Buyers should request mill test reports, material certificates confirming stainless‑steel grade, and, where required, a third‑party inspection report covering dimensions, pressure rating, and mesh tolerance.

Are there standard pressure ratings for the petroleum casing and well screen pipes?

Industry practice for similar stainless‑steel pipe products follows API 5L and ASTM A252 specifications, with common pressure ratings up to 150 bar (≈2 500 psi) depending on pipe diameter and wall thickness.

How are the screen pipes typically packaged for export?

Screen pipes are usually bundled in wooden crates or steel‑framed pallets, wrapped in moisture‑resistant film, and loaded into 20‑ft or 40‑ft containers to protect against deformation and corrosion.

Which global regions import Chinese stainless‑steel wire‑mesh products most frequently?

Major importers include countries in the Middle East, Africa, Southeast Asia, and Latin America, where the products are used in oil‑field, water‑well, and infrastructure projects.

What certifications are commonly required for stainless‑steel pipe and mesh imports?

Importers typically require ISO 9001 quality‑management certification, CE marking for mechanical conformity, and material‑specific certificates such as mill test reports or third‑party inspection certificates.

What Incoterms are usually applied to shipments from Huadong Screen Company?

Shipments are often quoted on FOB terms from major Chinese ports such as Shanghai or Ningbo, with buyers arranging CIF or DAP based on their logistics preferences.
