About Qingdao Huasu Machinery Co., Ltd. - Extrusion Machines Supplier in China

China‑based Qingdao Huasu Machinery Co., Ltd. lists six active products focused on extrusion equipment for double‑wall corrugated piping. The catalogue includes three pipe models - Sbg800, Sbg500 and Sbg315 - each described as HDPE/PP double‑wall corrugated pipe products, as well as two complete extrusion lines (Double wall corrugated pipe extrusion line and Sbg63 double wall corrugated pipe line) and a repeat entry for the Sbg800 extrusion unit. All items fall under the broader categories of Extrusion Machines, Industrial Tubes and Extrusion Plants as indicated in the supplier profile.

The supplier’s product set concentrates on machinery that produces HDPE and PP double‑wall corrugated pipes, a common component in water conveyance, irrigation and drainage systems. Each machine model is identified by its nominal pipe diameter (e.g., 800 mm for the Sbg800 series) and is positioned within the extrusion plant segment, reflecting a focus on large‑scale pipe production rather than finished pipe sales.

Product Range and Specialties of Qingdao Huasu Machinery Co., Ltd.

The listed extrusion lines are designed for continuous production of HDPE or PP double‑wall corrugated pipes. In the industry, such pipes are typically manufactured to HDPE grades PE100 or PE80 for water applications and PP‑R grades for higher temperature resistance. Standard specifications include pipe outer diameters from 63 mm up to 800 mm, wall thicknesses ranging 3 mm to 15 mm, and pressure classes PN10 to PN20, conforming to ISO 4437 and EN 1317. Machine capacities are often expressed as line speed (e.g., 30 - 60 m/min) and output volume (e.g., 1000 m³ per shift).

Typical extrusion plants incorporate twin‑screw extruders, vacuum cooling chambers, longitudinal cutting units and automated stacking. Buyers frequently request features such as PLC control panels, variable speed drives, and optional inline testing stations for dimensional and pressure verification. The Sbg63 line, for instance, targets smaller‑diameter pipe markets, while the Sbg800 line serves large‑diameter, high‑throughput projects.

Trade and Export Information - Qingdao Huasu Machinery Co., Ltd.

China is a major exporter of extrusion machinery, supplying equipment to construction and infrastructure projects across Southeast Asia, the Middle East, Africa and Latin America. Export shipments of pipe extrusion lines usually move in 20‑ft or 40‑ft containers, with standard freight terms such as CIF or FOB. Buyers commonly require compliance with ISO 9001 quality management systems and may request third‑party inspection reports (e.g., SGS, Bureau Veritas) before shipment. Although the catalogue does not list HS codes, extrusion machines of this type are generally classified under HS 8479.89, while the finished pipe products fall under HS 3917.00 for plastic tubes and pipes.

Regulatory considerations for the destination market often include local standards for potable water pipes (e.g., NSF/ANSI 61 in the United States, DIN 8077 in Europe) and certification of material safety. Export documentation typically comprises the commercial invoice, packing list, certificate of origin, and any applicable test certificates for material grade and mechanical performance.

Sourcing from Qingdao Huasu Machinery Co., Ltd. - Buyer Guidance

Prospective buyers should request the machine technical data sheet, including rated power consumption, extrusion temperature range, line speed, and maximum pipe diameter. Verification of material compatibility - specifically whether the equipment is certified for HDPE PE100 and PP‑R grades - is essential, as is a recent ISO 9001 audit report for the manufacturing facility. Sample production runs or video demonstrations can help confirm surface finish, corrugation depth and dimensional accuracy of the output pipe.

In addition, buyers are advised to obtain a detailed list of spare parts, warranty terms and on‑site installation support options. Typical order lead times for complete extrusion lines range from 12 to 20 weeks, depending on configuration and optional accessories. Packaging is usually in wooden crates with internal cushioning, loaded onto pallets that fit standard 20‑ft containers.

What pipe diameters can be produced with the Sbg800 extrusion unit?

The Sbg800 line is rated for outer diameters up to 800 mm, allowing production of large‑diameter HDPE or PP double‑wall corrugated pipes used in main water mains.

Does the Double wall corrugated pipe extrusion line support both HDPE and PP materials?

Yes, the line is specified for processing either HDPE (e.g., PE100) or polypropylene grades, provided the temperature profile is adjusted according to the material datasheet.

Which international standards are relevant for the pipes produced by these machines?

Typical standards include ISO 4437 for plastic pipes, EN 1317 for road and drainage applications, and ASTM D3350 for HDPE resin specifications.

What documentation should a buyer request before purchasing the extrusion equipment?

Buyers should request the machine’s technical data sheet, ISO 9001 certification, recent third‑party inspection report, and material compatibility declaration for HDPE and PP.

What are the common packaging and shipping arrangements for these extrusion lines?

Machines are shipped in wooden crates on standard pallets, fitted for 20‑ft or 40‑ft containers, often under CIF or FOB terms.

What is the typical lead time for delivery of a complete extrusion plant?

Lead times generally range from 12 to 20 weeks after order confirmation, depending on configuration, optional accessories and final testing requirements.

Are sample pipes or trial runs available before final purchase?

Suppliers usually arrange a pilot production run or provide video of the line in operation to demonstrate pipe dimensions, corrugation profile and surface quality.

What certifications are commonly required by importers of pipe extrusion equipment?

Importers often require proof of ISO 9001 quality management, CE marking for equipment safety, and a third‑party inspection certificate such as SGS or Bureau Veritas.
