Buyer questions

Questions about HDPE Double-Wall Corrugated Pipe

What do I need to specify for SN4 or SN8?

State the ring-stiffness class required by the project design alongside pipe size and site conditions. SN4 and SN8 are listed catalogue classes; the site does not provide a burial-design calculation.

How is the pipe joined?

The catalogue lists bell-and-spigot joints with a rubber seal. Request the selected pipe's socket dimensions and seal details to confirm the assembly.
