Hemoglobin is the iron-bearing and oxygen-carrying component of red blood cells. The normal value for hemoglobin varies by age and gender. Anemia is generally considered when hemoglobin concentrations fall below 11 g/dL for pregnant women, 12 g/dL for non-pregnant women, and 13 g/dL for men.emoglobin is the iron-bearing and oxygen-carrying component of red blood cells.

A soil pipe is a PVC or cast iron pipe used in plumbing installations to remove soiled or contaminated water from toilets. Soil pipes differ from normal waste water removal pipes in that they are generally of a larger diameter and are designed specifically to remove solid waste from toilets.
Down pipes. A down pipe is a drain pipe that deviates no more than 45Âº from vertical. A down pipe connects a collector to a ground pipe and is outfitted with a pressure-relief pipe. In a soil & waste system, the design must focus on preventing large pressure difference in down pipes. ground pipe is a horizontal pipe that collects drainage flows from connectors, collectors and down pipes and discharges them into the external sewer. The ground pipe remains inside the 0,5 m boundary of the internal sewer.
