4 Inch HDPE Pipe | PE100 Water Supply & Drainage Pipe
What Is a 4 Inch HDPE Pipe?
A 4 inch HDPE pipe (High-Density Polyethylene pipe) is a thermoplastic piping solution widely used in water supply, drainage, irrigation, gas distribution, and industrial fluid transport systems. With an outside diameter of approximately 110 mm, 4-inch HDPE pipes are typically manufactured according to international standards such as ISO 4427, EN 12201, ASTM D3035, and ASTM F714.

Addressing Your Top Worries
Quality You Can Trace
Worried about standards? Don't be. This 4 in HDPE pipe meets ASTM D3035 (the gold standard for HDPE water pipes) and NSF 61 (safe for drinking water). Every inch is marked with its pressure rating, material grade, and batch number - so you know exactly what you're getting, down to the details.
Packaging That Protects
Shipment stress? Not here. Pipes come in 6m or 12m lengths, bundled tight with steel straps and capped with plastic ends to fend off dings. Bulk orders ride on pallets, secure and ready to roll - no bent ends, no damaged walls, just pipes in perfect shape, right when you need them.

Where It Shines
This 4 inch HDPE pipe isn't picky - it excels everywhere:
- Residential main water lines (quiet, reliable, rust-free)
- Commercial building supply (keeps up with high demand)
- Golf course irrigation mains (precise flow, no clogs)
- Industrial cooling water pipes (tough against chemicals)
Why It Beats Steel Pipes Hands Down
Steel's heavy, rusts, and clogs - this pipe? Light as a feather (70% lighter than steel), so installation costs plummet. No rust means no blockages, no maintenance downtime, and water that stays clear, not cloudy. It's not just a replacement - it's an upgrade.
Installation & Maintenance Tips
Fusion Know-How
Grab a 4 inch butt fusion machine, heat those pipe ends to 190-200°C, then press 'em together with steady pressure (check your machine manual for the sweet spot). The result? A bond that's stronger than the pipe itself.
Burial Basics
Bury it at least 1.0m deep - deep enough to laugh off vehicle loads and harsh weather. Backfill with sand or gravel, not rocks - soft bedding keeps the pipe safe from scratches and dents.

FAQs
Q: Fire sprinkler systems?
A: You bet. Go with the PN2.0MPa SDR9 grade (just check local fire codes to be safe).
Q: Maximum flow rate?
A: Around 60 m³/h at 1.0MPa - adjusts with pressure and length, but it's always efficient.
This 4 inch HDPE pipe isn't just a piece of hardware - it's a promise: to deliver water reliably, durably, and efficiently, in every project, big or small.
