Where are 45 degree elbows used?
Elbow in the pipeline system , elbow is to change the direction of the pipe fittings. According to the angle, there are 45 ° and 90 ° 180 ° three most commonly used, in addition, according to engineering needs also include 60 ° and other non-normal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable iron, carbon steel, non-ferrous metals and plastics. Connected to the pipe in the following ways: direct welding (the most common way) flange connection, hot fusion connection, electrofusion connection, threaded connection and socket connection. According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, etc.. 1. Divided by material.
