AQUATHERM NORTH AMERICA DESIGN & PLANNING

STANDARD DIMENSION RATIO Aquatherms pipes are manufactured using a standard dimension ratio (SDR), meaning the wall thickness is a ratio of the total diameter. This is different from schedules, which are commonly used in North America, but is typical of fusible plastics. As a result, all pipe sizes in a given SDR have the same pressure ratings.

The Standard Dimensional Ratio (SDR) is used to describe the relationship between pipe diameter and wall thickness, and therefore, the pressure rating of the pipe. The ratio between the pipe OD and wall thickness remains constant for all pipe sizes for a given pressure rating, and can be eed by a Polypropylene Pressure Piping Technical Handbook A.

SDR - Standard Dimension Ratio of Plastic Pipe » The

Standard dimension ratio (SDR) is a method of rating a pipes durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. Common nominations are SDR11, SDR17 and SDR35. Pipes with a lower SDR can withstand higher pressures.

An SDR 11 pipe is outer diameter 'D' of the pipe is eleven times the thickness 'S' of the wall diameter A higher SDR means, a lesser pipe thickness with a lesser pressure rating.
