About China Hovoy - Stainless Steel Pipes & Pipe Fittings Supplier in China

China Hovoy is registered in China and currently lists five distinct pipe products in its catalogue. The active product count of five includes Heat Preservation GRE Pipe, UV Resistance GRE Pipe, GRP Pipe, Amine Cured GRE Pipe and Anhydride Cured GRE Pipe, each classified under HS chapter 39 with the code 3917.23 where specified. The listed products fall under the broader categories of Stainless Steel Pipes & Pipe Fittings, Steel Pipes, Agriculture and Steel Tubes, indicating a focus on engineered piping solutions for industrial and agricultural use. The catalogue explicitly describes the material composition of each pipe, ranging from glass‑reinforced epoxy composites with thermal insulation to fiberglass‑reinforced thermosetting resin matrices.

The product set comprises glass‑reinforced epoxy (GRE) and glass‑reinforced plastic (GRP) pipes that are commonly used for water, irrigation, chemical transport and low‑pressure gas applications. While three of the items provide an HS code (3917.23), the Amine Cured GRE Pipe entry lacks a code in the supplied data, and therefore no HS code is assigned to it here. All five items are described by their cure system or reinforcement type, which aligns with typical industry classifications for composite piping. The supplier’s catalogue does not include any declared certifications, so any certification status must be verified directly with the supplier.

Product Range and Specialties of China Hovoy

China Hovoy’s catalogue lists five composite pipe variants built from glass‑reinforced epoxy or plastic matrices. The Heat Preservation GRE Pipe incorporates a thermal insulation layer, the UV Resistance GRE Pipe uses a UV‑stable resin system, the GRP Pipe relies on an E‑glass fiber reinforced thermosetting resin, and the Anhydride Cured GRE Pipe employs an anhydride cure chemistry. These products are typically offered in diameters from 25 mm to 200 mm and can be supplied in lengths of 6 m or 12 m, matching common specifications in the composite pipe market. Industry standards such as ISO 14692 (Petroleum and natural gas industries) and ASTM D2996 (GRP pipe) define pressure ratings up to 2 MPa (≈ 20 bar) and operating temperature ranges from - 30 °C to +80 °C for similar GRE/GRP pipes.

Trade and Export Information - China Hovoy

Exporters of GRE and GRP pipes from China frequently ship to the Middle East, Africa, Southeast Asia and Latin America, where the demand for corrosion‑resistant water and irrigation infrastructure is high. The HS code 3917.23 covers “tubes, pipes and hoses, of plastics, reinforced or otherwise combined with other materials,” and customs authorities often require a certificate of origin and a compliance declaration for this chapter. Buyers typically request ISO 9001 quality‑management certification, ISO 14001 environmental compliance, and where applicable CE marking for European markets. Standard packaging involves bundling the pipes on wooden pallets, with each 20 ft container holding approximately 12 tons of product, while 40 ft containers can accommodate up to 22 tons. Common Incoterms used by Chinese pipe exporters include FOB Shanghai and CIF Dubai, reflecting the logistics routes preferred for bulk pipe shipments.

Sourcing from China Hovoy - Buyer Guidance

When sourcing GRE or GRP pipes from China Hovoy, buyers should request the material data sheet that specifies the resin type, fiber content, cure system and mechanical properties such as tensile strength (typically 150 - 250 MPa) and burst pressure. Test reports conforming to ASTM D2996 or ISO 14692 should be examined to confirm pressure rating and dimensional tolerance. Because the catalogue does not list any certifications, buyers need to ask for copies of ISO 9001 or other relevant certificates before placing a purchase order. Samples of the pipe sections, especially for the heat‑preservation and UV‑resistant variants, are advisable to verify insulation performance and UV‑stability under the intended service conditions.

What material standards apply to the GRE pipes listed by China Hovoy?

The GRE pipes are based on glass‑reinforced epoxy composites, which are commonly produced to meet ASTM D2996 and ISO 14692 specifications for pressure‑rated composite piping.

Which HS code covers the majority of China Hovoy’s pipe products?

Three of the five listed pipes are classified under HS code 3917.23, which covers reinforced plastic tubes, pipes and hoses.

What certifications should a buyer request from China Hovoy before ordering?

Buyers should request ISO 9001 quality‑management certification and, if required for the destination market, ISO 14001 or CE marking documentation.

What typical pressure rating can be expected from the listed GRE pipes?

Composite GRE pipes in this category are generally rated for up to 2 MPa (≈ 20 bar) burst pressure, subject to confirmation by the supplier’s test report.

How are the pipes typically packaged for export?

Pipes are usually bundled on wooden pallets, secured with stretch film, and loaded into 20 ft or 40 ft containers, with container loads ranging from 12 to 22 tons depending on pipe diameter and length.

What Incoterms are most commonly used for shipping these pipes from China?

Exporters from China often use FOB Shanghai for buyer‑arranged freight or CIF Dubai for delivered‑to‑port shipments, reflecting standard logistics for bulk pipe cargo.

Is a sample available for the UV Resistance GRE Pipe?

Buyers can request a sample of the UV‑resistant GRE pipe to evaluate UV‑stability and mechanical performance before confirming a larger order.

What documentation is needed to verify the cure system of the Amine Cured GRE Pipe?

A technical data sheet describing the amine cure chemistry, along with a recent laboratory test report confirming tensile strength and thermal resistance, should be obtained.
