European pipe is standardized to ISO 2531 and its descendent specifications EN 545 (potable water) and EN 598 (sewage). European pipes are sized to approximately match the internal diameter of the pipe, following internal lining, to the nominal diameter. ISO 2531 maintains dimensional compatibility with older German cast iron pipes.
Ductile iron pressure pipes with socket with cement-mortar lining for gas and water pipelines; dimensions and masses: Withdrawn: DIN EN 545, DIN EN 969: EN 545, EN 969: DIN 28610-2: Ductile iron pressure pipes with socket for gas and water pipelines rated for pressures over 4 bar up to and including 16 bar; dimensions and masses: Withdrawn: DIN ...
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Standard dimension ratio (SDR) is a method of rating a pipe's durability against pressure. The standard dimension ratio describes the correlation between the pipe dimension and the thickness of the pipe wall. [1] Common nominations are SDR11, SDR17, SDR26 and SDR35. Pipes with a lower SDR can withstand higher pressures.
Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA ( Ductile Iron Pipe Research Association ), and was first used in 1922 in Charleston, South Carolina .

Both the World Health Organization and the American Heart Association suggest increasing potassium intake to at least 3,510 milligrams per day to help lower blood pressure and reduce the risk of ...
During the IPS period, pipes were cast in halves and welded together, and pipe sizes referred to the inside diameters. [1] The inside diameters under IPS were roughly the same as the more modern Ductile Iron Pipe Standard (DIPS) and Nominal Pipe Size (NPS) Standards, and some of the wall thicknesses were also retained with a different ...
