Hello to all our contractors, purchasers, and industry partners!
Today, we invite you on a virtual tour of our modern production facility. Get an up-close look at how raw materials are transformed into a high-quality, 560mm PN16 white co-extruded HDPE pipe — a powerful tool for your engineering projects.
At Shandong SIFFO Plastic Technology Co., Ltd., the featured 560mm PN16 white co-extruded HDPE pipe combines a black polyethylene pipe body with a white outer layer.
▎A Closer Look at the Featured Pipe
The pipe features a nominal outside diameter of 560mm and a PN16 pressure designation, making it relevant to large-scale water transfer and other engineered pressure-pipeline projects.
| Item | Featured specification |
|---|---|
Product | White co-extruded HDPE pipe |
Nominal outside diameter | 560mm |
Nominal pressure designation | PN16 |
Material identification | PE100 |
Exterior | White co-extruded outer layer |
Interior | Black HDPE |
Typical jointing method | Butt fusion, using compatible materials and approved procedures |
560mm Diameter: Meets the requirements for high-volume fluid transport in large-scale municipal water supply and drainage, water conservancy projects, and industrial sewage disposal.
PN16 (1.6 MPa): Offers exceptional pressure-bearing capacity and a high safety margin, making it an ideal choice for high-pressure water conveyance applications.
▎Why Use a White Co-Extruded Outer Layer?
Reduced Solar Heat Absorption
Black polyethylene pipes exposed to direct sunlight can reach temperatures above the surrounding air. A reflective white exterior can reduce solar heat absorption under comparable conditions, helping manage the temperature of an exposed pipeline. This is an established design principle used in white-shell polyethylene piping.
For agricultural, mining and industrial installations with above-ground sections, this makes white co-extruded HDPE pipe an option worth evaluating.
Integrated During Manufacturing
The white exterior is formed through co-extrusion during pipe manufacture. This produces the outer layer as part of the pipe construction and avoids a separate painting operation after production.
Practical HDPE Performance
The polyethylene pipe body offers corrosion resistance, flexibility and compatibility with fusion jointing. These characteristics support applications where soil conditions, terrain or corrosion can complicate the installation and maintenance of metal pipelines.
For industrial fluids and mining slurry, material suitability should also be assessed against chemical composition, temperature and wear conditions.
Control at the Source
High-quality raw materials serve as the foundation. Upon entering the raw material zone of the workshop, one is greeted by neatly stacked, premium-grade polyethylene (PE) and massive silver storage silos. We consistently utilize high-quality, virgin PE100-grade resin, strictly avoiding the inclusion of any recycled material. Through an automated feeding system, the raw material is precisely conveyed to the extrusion equipment—ensuring, from the very source, the exceptional physical properties and extended service life of our pipes.
Quality Priorities for Large-Diameter Pipe
For engineering buyers, product appearance is only one part of a supply evaluation. A 560mm PN16 white co-extruded HDPE pipe order should also be reviewed against:
Outside diameter, wall thickness and ovality.
Outer-layer thickness and consistency.
Inner and outer surface condition.
Hydrostatic testing required by the agreed standard.
Product marking and batch traceability.
Project-specific inspection and documentation requirements.
The applicable test records and certification scope should correspond to the exact product being supplied.
Applications Across Water, Irrigation and Industry
Subject to project-specific engineering approval, this pipe configuration can be considered for several applications.
Bulk water transfer: Large-diameter mains connecting water sources, storage facilities and distribution systems.
Agricultural irrigation: Mainlines supplying farms and irrigation districts, including exposed sections where solar heating needs consideration.
Mining water systems: Process-water supply, dewatering and selected slurry services following pressure, chemical compatibility and wear assessment.
Industrial water networks: Utility-water and cooling-water infrastructure requiring corrosion-resistant piping.
Above-ground installations also require suitable support spacing, thermal movement allowances, anchorage and protection against mechanical damage.
