In regards to storm water management it is most commonly used when a contractor would like to or needs to have a stronger pipe with a smooth outer and inner wall compared to schedule 20 pipe, mentioned below.

Website: Askingthelot. Strong , Sdr , Strength , Stiffness , Such. All sizes with the same SDR rating have the same pressure rating.

A pipe can be identified by SDR number or by class number, but workers in irrigation are more likely to call a pipe "class " than " SDR Website: Sizes. Website: Petersenproducts. Span , Strong , Sdr.

Strong , Sdr , Sewer , Systems , System. Hello All, I'm a Municipal Engineer specializing in sewer work point repairs, lining, etc.

I laid pipe for awhile while getting my degree, and I've been around the smell of money for awhile. We do a lot of construction administration and I've worked and inspected on multiple jobs involving that.

Per the ingenious "Iowa formula" for buried pipes developed by Professor Spangler from my alma mater decades ago, a distribution of vertical load in the numerator of the equation causing deformation of a pipe with walls that move outward against the sidefill soil is resisted by a factored combination of pipe stiffness PLUS soil stiffness in the denominator of the equation.

Aye, "Therein lies the your rub". What you are talking about "on paper" obviously didn't translate to the real world. You are not the only one having such problems. In fact, there have been many field problems where very low long-term stiffness plastic pipes have been over-deflected, collapsed, or exhibited other problems related to deformation.

While some Engineers have basically tried to make the Contractor responsible for making whatever pipe they specify work, with any manner of soils, depths, and field conditions "work" and then simply blamed them or others when it didn't after the fact , some authorities have indicated an Engineer's charge with regard to very low, long-term stiffness plastic pipes should go much deeper, so to speak, and in reality not all pipes may be suitable for all conditions.

SDR 26 will perform better under less than perfect installation conditions. The price difference should not be significant. When I called to ask about it, they said that the price difference wasn't much and it was easier to install, so they always used SDR 26 even if SDR 35 was specified.

They have been established to simplify standardization in the specification of plastic pipe on an international basis. Since these define a constant ratio between outer diameter and wall thickness, they provide a simple means of specifying product dimensions to maintain constant mechanical properties regardless of pipe size.

In other words, for a given DR or SDR, pressure capacity and pipe stiffness remain constant regardless of pipe size.
