Import Corrugated Pp Pipe Production Line — Buy in Bulk from Supplier in China

The Corrugated PP Pipe Production Line supplied by Weifang Zhongyun Science And Research Co. Ltd. is a complete extrusion system designed for double‑wall polypropylene pipe manufacturing. It features a 250h corrugator capable of producing pipes with outer diameters from 90 mm to 250 mm. An innovative mould‑block cooling solution accelerates the cooling cycle, raising line efficiency. The line also incorporates a rapid‑assembly clasp style for quick mould‑block changes.

The equipment processes PP or PE material to create double‑wall corrugated pipes that meet typical industry grades such as PP‑R or PE100, with wall thicknesses generally ranging from 3 mm to 10 mm depending on diameter. Standard tolerances for pipe roundness are ±0.5 mm and concentricity within 0.3 mm, which the line can maintain through its bidirectional mould‑block drive. The interchangeable mould blocks follow a standardised system, allowing the same line to switch between pipe sizes without extensive re‑tooling. These features align with common production practices for water conveyance, irrigation and drainage networks.

Buyers such as municipal water utilities, agricultural contractors and infrastructure developers typically source this line to build in‑house pipe capacity. The supplier offers the line on an FOB basis from the port of Qingdao, with packaging in a steel‑framed crate to protect components during transit. Because the listing does not disclose MOQ, lead time or payment terms, interested importers should confirm these details directly with the supplier before placing an order.

Weifang Zhongyun Science And Research Co. Ltd. is located at No.777 Dongfang Road, New‑high‑Tech Zone, Weifang, Shandong 261061, China. The company is classified in the harbor trust tier and currently shows a 0 % response rate on the platform, indicating limited recent communication activity. It specialises in manufacturing, exporting and supplying complete corrugated pipe extrusion lines and associated machinery.

Zhongyun claims to be the only Chinese enterprise that has produced all three types of corrugators for PE/PP double‑wall pipe machines, and it positions itself as a leading supplier in Asia for this equipment. The listing does not provide specific production volumes, certifications or client references, so buyers should request verification of factory capability and any applicable quality certificates.
