Four main factors determine corrugated pipe price: diameter, SN class (SN4 or SN8), standard length, and order quantity. Rather than a fixed price list, quotes are built around these variables; this guide explains each factor and answers the most common diameter-based questions about double-wall corrugated HDPE pipe.
As the diameter increases, the amount of HDPE raw material and production time both increase, which directly affects cost. Smaller diameters are used for garden and plot drainage or cable protection, while larger diameters serve major infrastructure and sewer lines. The table below summarizes common diameters and typical applications.

SN4 corrugated pipe is produced with a thinner wall rated for 4 kN/m² ground load and suits lighter applications such as garden or agricultural drainage. SN8 requires a thicker wall structure rated for 8 kN/m², which is why it costs more and is used under roads and parking areas where traffic load is a factor.
A 6-meter length is the most common standard for corrugated pipe transport and installation, so quotes are typically built around this reference unit — for example, when comparing a double-wall corrugated pipe across different diameters. Custom lengths are evaluated separately per project.
Fittings such as couplers, elbows, reducers, and end caps are priced as separate line items from the pipe body. Their type and quantity are distinct cost components when planning a drainage line.
Coupler/sleeve: joins two pipe ends with a sealed connection
45° / 90° elbow: used where the line changes direction
Reducer: connects two pipes of different diameters
End cap: closes off the end of a line
A corrugated pipe is made from HDPE with a ribbed outer wall and smooth inner bore, giving it higher ground-load resistance for deep burial and heavy traffic use. A plain PVC pipe is generally used for indoor drainage, clean water transport, and lighter applications rather than deep infrastructure lines.
Diameter, SN class, length, and order quantity vary by project, so quotes are prepared individually rather than from one fixed list.
A double-wall corrugated pipe combines a ribbed outer wall for strength with a smooth inner wall for flow efficiency, making it suitable for drainage, stormwater, and cable protection lines.
For large diameters such as Ø1000 mm, the price is determined mainly by HDPE material volume, SN class, production time, and the higher freight volume required for transport.
Yes, couplers and other fittings are separate product items and are ordered according to project requirements.
Unit production and freight costs generally trend lower as order volume increases, though the exact rate depends on the project and diameter.
There is no fixed figure; cost depends on diameter, SN class, length, and order quantity. Contacting the manufacturer directly is recommended for a current quote.
It is made from high-density polyethylene (HDPE), which provides chemical resistance, flexibility, and long-term durability for buried applications.
The most common types are couplers, 45°/90° elbows, reducers, and end caps, each used at a different point in a drainage line.
The most common industry-standard length is 6 meters; custom lengths are evaluated separately per project.
