About Haiyan New Century Petrochemical Device Co., Ltd. - Industrial Filters Supplier in China

Haiyan New Century Petrochemical Device Co., Ltd. is based in China and currently lists five active products in its catalogue. The catalogue contains metal pall ring, metal nutter ring, metal saddle ring, metal improved pall ring, and metal raschig ring. All items fall under the broader classification of industrial filter components used in packed‑column applications. The supplier is recorded as an imported tier with a harbor trust rating, indicating that it is primarily engaged in export activities from Chinese manufacturing hubs. The product count and categorical focus suggest a specialization in metal‑based filtration media rather than a broader machinery line.

The five metal ring products are typical forms of structured packing: pall rings, improved pall rings, saddle rings and raschig rings, each offering different surface area and void fraction characteristics. These rings are commonly fabricated from carbon steel or stainless steel and are supplied in standard diameters ranging from 25 mm to 150 mm. The catalogue does not provide HS codes, so the description remains confined to the product names and their functional class within industrial filtration systems.

Product Range and Specialties of Haiyan New Century Petrochemical Device Co., Ltd.

The catalogue lists five distinct metal ring designs: pall ring, nutter ring, saddle ring, improved pall ring and raschig ring. In the industrial filtration market, such rings are classified as packing media for chemical reactors, petrochemical distillation columns and water‑treatment towers. Typical specifications include material grades such as stainless steel 304/316 for corrosion‑resistant applications, carbon steel for lower‑cost installations, and dimensional tolerances of ±0.5 mm on outer diameter. Standard pressure ratings often exceed 2 MPa, and bulk densities range from 0.30 to 0.55 g/cm³ depending on the geometry.

Buyers usually evaluate these rings by surface area (m² per unit), void fraction (30‑45 %), and mechanical strength. Industry standards such as ASTM A193 for stainless steel fasteners or EN 10204 for material test certificates are frequently referenced. The supplier’s product list aligns with these norms, offering a selection that can be matched to the typical grade and size requirements of petrochemical and water‑treatment projects.

Trade and Export Information - Haiyan New Century Petrochemical Device Co., Ltd.

China is a major exporter of metal‑based filtration media, with shipments directed to Southeast Asia, the Middle East, Europe and North America. Exporters of industrial filter rings typically comply with ISO 9001 quality management systems and may provide CE conformity declarations for EU markets. Common HS chapters for these items fall under heading 7318 (cast articles of iron or steel) or 7616 (other aluminium articles), depending on the material, but the catalogue does not specify exact codes for each product. Logistics for packed‑column media usually involve 20 ft or 40 ft containers, wooden crates or bulk bags, and Incoterms such as FOB Shanghai or CIF Rotterdam are regularly used.

Regulatory considerations include compliance with REACH for European buyers and the U.S. Toxic Substances Control Act (TSCA) for North American imports. Buyers often request material test reports, mill certificates and, where applicable, corrosion‑resistance test data before shipment. The supplier’s harbor trust tier suggests familiarity with maritime export procedures and standard containerization practices for metal packing media.

Sourcing from Haiyan New Century Petrochemical Device Co., Ltd. - Buyer Guidance

When sourcing metal filter rings from this supplier, request a detailed material certificate indicating the exact steel grade (e.g., SS 304, SS 316 or carbon steel) and the corresponding mechanical properties. Verify the dimensional drawing for outer diameter, wall thickness and hole size, as these parameters affect column performance and pressure drop. Ask for a batch test report covering surface area, void fraction and bulk density to confirm that the product meets the specifications required for your process design.

In addition to material certificates, ask for compliance documents such as ISO 9001 certification, CE Declaration of Conformity (if targeting the EU) or any applicable REACH registration numbers. Request a sample batch packaged in the same manner as the commercial shipment (typically wooden crate with internal cushioning) to evaluate handling and dimensional tolerance. Confirm the minimum order quantity, typical lead time (often 4‑6 weeks for stainless‑steel rings) and the preferred Incoterm before finalizing the purchase order.

What types of metal filter rings are listed by Haiyan New Century?

The supplier lists metal pall ring, metal nutter ring, metal saddle ring, metal improved pall ring and metal raschig ring, all used as packing media in chemical and water‑treatment columns.

Which material grades are commonly offered for these rings?

Typical grades include stainless steel 304 or 316 for corrosion‑resistant applications and carbon steel for cost‑sensitive installations; the supplier’s catalogue does not specify grade per item, so buyers should request the exact material certificate.

What are the usual dimensions for industrial filter rings?

Standard outer diameters range from 25 mm to 150 mm with wall thicknesses of 2‑8 mm; tolerances are generally ±0.5 mm, but exact dimensions should be confirmed with the supplier’s technical drawing.

Which certifications should a buyer request from this supplier?

Buyers should request ISO 9001 quality management certification, material test certificates (mill certificates), and, for EU shipments, a CE Declaration of Conformity or REACH registration evidence.

What is the typical packaging method for these metal rings?

They are usually packed in wooden crates or bulk bags with internal cushioning to prevent deformation, and the crates are loaded into 20 ft or 40 ft containers for ocean freight.

What are common Incoterms used for exporting these products from China?

Exporters frequently use FOB Shanghai or CIF ports such as Rotterdam or Singapore, depending on the buyer’s preferred logistics arrangement.

What is the usual lead time and minimum order quantity?

Lead times are generally 4‑6 weeks after order confirmation, and minimum order quantities often start at a single container load, but the exact MOQ should be verified with the supplier.

Which regions typically import metal filter rings from China?

Key import markets include Southeast Asia, the Middle East, Europe and North America, where the rings are used in petrochemical plants, refineries and water‑treatment facilities.
