What are the types of elbow pipe fitting

What is elbow pipe fitting The elbow is used to change the direction of the pipe. The bending angles of commonly used elbow pipe fitting are 90°, 45° and 180°. The 180° elbow is also called U-shaped elbow. There are also special angle elbow pipe fitting , but there are very few elbow pipe fitting. The types of elbow pipe fitting are as follows: 1. Malleable steel elbow Malleable iron elbow, also known as malleable cast iron elbow, is the most common threaded elbow. The specifications of malleable steel elbow pipe fitting are relatively small, and the commonly used specifications range from 1/2 to 4 inches. According to their different surface treatments, they are divided into galvanized and non-galvanized. This kind of malleable steel pipe fittings are mainly used for heating, water pipes and gas pipes. In the process, except for the low-pressure pipeline that needs to be frequently disassembled, other material pipelines are rarely used. 2. Pressed elbow Pressed elbow pipe fitting, als...
