Import Hdpe Plastic-Steel Large Diameter Pipe Machine — Buy in Bulk from Supplier in China

The HDPE plastic‑steel large diameter pipe machine supplied by Qingdao Longchangjie Machine Co, Ltd. is designed to extrude high‑density polyethylene pipes reinforced with steel for diameters exceeding standard sizes. It incorporates a composite die system that minimizes material waste while maintaining dimensional accuracy. The machine is built for continuous operation and integrates with existing production lines without major re‑engineering. Supplier information indicates a robust steel frame suited for heavy industrial environments.

Composite die technology is a recognized method for producing large‑diameter pipe with consistent wall thickness and surface finish, and it aligns with industry standards for pipe manufacturing. The use of HDPE provides excellent chemical resistance and flexibility, while the steel reinforcement adds tensile strength required for high‑pressure applications. Typical installations operate at 380 V, 50 Hz three‑phase power and weigh between five and ten tonnes, reflecting common size for this class of equipment. Standard control interfaces are PLC‑based, enabling precise speed and temperature management.

Target users include manufacturers of water supply, wastewater treatment and construction infrastructure who need to expand their product range or increase throughput. The machine can be ordered under flexible trade terms such as FOB or CIF, subject to confirmation with the supplier. Buyers should verify certification documents, installation support and after‑sales service before finalising the purchase.
