pipe thickness in metallic buried piping
pipe thickness in metallic buried piping
(OP)
Hello all,
I would like to know if there is some restricction to select the minimun wall tickness in metallic buried pipes?
In the european code EN-13480, the part 6 (Requirements for buried piping) there is a table with the following restricctions for the wall thickness:
DN Mininum Thick.
mm
DN <=80 3,2
80<DN<=150 4,7
150<DN<=450 6,35
450<DN<=600 7,9
600<DN<=950 9,5
I would like to know if can I use less thickness than shown in the table. Could anyone let me know if in others codes exist a restrictions like that?
Thanks you in advance.

Canadian Code CSA-Z662 does have a similar minimum thicknesses.

What do you mean when you said "limited to around 100"? 100?
Thanks in advance.

The reason is that the pipe is stainless steel (each mm of material increase the cost) and the fluid is not dangerous. This is the reason because I would like to select less thickness.

The pipe has to be designed for external and soil loadings. many culverts are built wihtt a very ow wall thickness as the loads are carried by the soil.
To design a thin wall buried pipe you need to investigate, stress, strain, deflection, strain, buckling and combined loading. Check out AS 2566
