Large Diameter Pipe FAQs

What are large diameter CSR pipes?

CSR stands for composite steel reinforced. CSR pipes are reinforced with a steel core for exceptional strength, designed to act as a low-carbon alternative to traditional concrete pipes. Large diameter CSR pipes are those with a wider internal width, allowing for greater flow rates. 

What sizes qualify as large diameter CSR pipes?

The definition of large diameter pipes will vary depending on the manufacturer or supplier, but generally large diameter drainage pipes are considered to be around DN400 (406mm) and up.

What are large diameter CSR pipes used for?

Large diameter CSR drainage pipes are used mostly for major infrastructure projects. They are highly durable and can accommodate heavy flow rates, making them ideal for larger developments.

What load ratings do large diameter CSR pipes offer?

The Aquaspira large diameter CSR pipes that we offer here at Drainfast have load ratings ranging between 2.3 kN/m² and 3 kN/m². This allows them to handle heavy loads such as large roads with high traffic.

What joining systems are used with large diameter CSR pipes?

Aquaspira CSR pipes are fitted with integral seals and spigot and socket joints, meaning joining is as simple as pushing two sections together. This provides a durable, reliable seal even in heavy use applications. 

Can large diameter CSR pipes be used for attenuation systems?

Absolutely. CSR drainage pipes are built with attenuation systems in mind, and are often used to connect subterranean stormwater storage tanks. They provide a strong, durable solution able to handle regular use as well as storm surges.Absolutely.
