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

The SJ series Corrugated Pipe Extrusion Line from Qingdao Royal Machinery Co., Ltd is a complete production system for extruding PE and PVC corrugated pipes. It is offered in three models - SJ30/25, SJ45/25 and SJ65/25 - each configured to match different output capacities. All models can accommodate up to 42 pairs of moulds, enabling high‑volume production of diverse pipe profiles. The line is capable of handling pipe diameters from 110 mm to 315 mm as a typical range for municipal drainage applications.

The equipment is built on a steel frame that meets industrial‑grade durability standards, reducing downtime under continuous operation. A water‑cooled mould block system provides rapid temperature control, which is a typical method for maintaining dimensional stability of PE and PVC walls. Energy consumption is optimised through a PLC‑based control panel that monitors motor loads and can achieve typical efficiencies around 85 percent. The user interface includes an HMI screen that allows operators to adjust speed, temperature and pressure without specialised training.

The line serves construction, plumbing and electrical installation firms that require on‑site or factory‑based pipe manufacturing. Importers can negotiate FOB or CIF terms and benefit from the supplier’s harbour‑level trust tier, although exact MOQ and lead time should be confirmed directly. Customisable options such as additional mould sets or auxiliary granule dryers are available to match specific project requirements.
