Water transportation using pipelines and piping dates back to the use of earthenware piping in ancient Greece and in Middle Eastern lands along with bamboo pipes in China (Baker, 1948).The Romans used concrete linings as well as carved out local rock.Oxygen and Corrosion of Steel Pipes - Engineering ToolBoxCorrosion of steel is strongly affected by the amount of oxygen in the water and the temperature of the water. The effects of oxygen and temperature on low-carbon steel pipes with water flow are indicated in the diagrams below 1 mm = 0.03937 in; T(o F) = [T(o C)](9/5) + 32; 1 ppm = 1 mg/liter; Oxygen - Solubility in Fresh Water and Sea Water
Straightness Tolerances for Pipe. The carbon steel pipe standards require only that the finished pipe shall be reasonably straight. ASTM A312M (in ASTM A999M) requires a welded stainless steel pipe to be straight to within 3.2 mm over 3.0 m lengths. Generally, the thumb rule is Piping KSBThe wall thickness (b) of steel pipes subjected to internal pressure are calculated in accordance with EN 13480-3. For pipes mainly subjected to static load conditions, the following roughly applies In the case of changes in temperature, the change in length of a straight pipe is calculated according to the following equation Open system
