Import Hdpe Double Wall Corrugated Pipe Extrusion Line — Buy in Bulk from Supplier in China

The HDPE Double wall corrugated pipe extrusion line offered by Weifang Zhongyun Technology Co., Ltd is a fully integrated production system that extrudes inner and outer walls with two separate extruders. It employs an efficient screw and a notched barrel, allowing distinct material feed for each wall. The line incorporates a corrugated forming system coupled with forced water and air cooling to maintain high production speed. The programmable lubricating system reduces mould abrasion and extends block life.

The equipment is designed primarily for HDPE but can be adapted to other thermoplastics such as LDPE and PP, matching the material flexibility seen in modern pipe‑manufacturing plants. The co‑extrusion die provides stepless adjustment of wall thickness, meeting or exceeding national state standards for pipe creep and sealing performance. Cast mould blocks are forged from a special alloy that delivers high dimensional precision and radiation resistance, a common requirement for long‑run extrusion lines. These features align with typical industry expectations for double‑wall corrugated pipe production.

Manufacturers of municipal drainage, irrigation networks and civil‑engineering infrastructure use this line to produce large‑diameter corrugated pipes for water conveyance and sewerage. The system’s quick‑change mould blocks and tele‑diagnosis communication reduce downtime, making it attractive to exporters and domestic contractors seeking reliable high‑volume output. Prospective buyers should request detailed quotation, verify CE certification and discuss Incoterms, payment schedule and MOQ directly with the supplier.

Weifang Zhongyun Technology Co., Ltd is located in the High‑Tech Development Zone of Weifang, Shandong Province, China (postal code 261000). The company is listed as an imported‑tier supplier and holds a harbor trust tier on the platform, indicating a basic level of verification. Its registered address on Dongfang North Road places it within a concentration of machinery manufacturers.

The supplier’s profile shows a response rate of 0 % and no average response time, which suggests that communication performance should be confirmed before initiating negotiations. The listing does not disclose production capacity, annual turnover or client references, so buyers are advised to request supporting documentation such as factory photos, equipment lists and quality certificates.
