Plumbing fittings classification method

Plumbing fittings in the elbow fittings classification: elbow fittings according to the radius of curvature to points, can be divided into long radius elbow and short radius elbow. Long radius elbow means that its radius of curvature is equal to 1.5 times the outside diameter of the pipe, that is, R = 1.5 D. Short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, that is, R = D. Where D is the diameter of the elbow, R is the radius of curvature. If the elbow fittings pressure level to points, there are about seventeen, and the U.S. pipe standard is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, of which the two commonly used are STD and XS. According to the angle of elbow fittings, there are 45o elbows, 90o elbows and 180o elbows. In this way, the types of elbow fittings is a lot of ordering orders are often taken as follows: such as "LR STD 90o 8", said the long radius, pressure level of STD, 90o 8 "elbow; and, for example, "SR XS 45o 4" said the short radius, the pressure level of the XS, 45o 4 "bend; the above is the elbow fittings for the approximate classification of the situation.
