What is an elbow:

In fire fighting fittings systems, elbows are fittings that change the direction of a pipe. According to the angle, there are three most commonly used 45 degrees, 90 degrees and 180 degrees, and other abnormal angle elbows such as 60 degrees are included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The ways to connect with the pipe are: direct welding (the most common method) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

Malleable iron pipe fittings are pipe fittings made through molding, melting, pouring, annealing, scraping, polishing, galvanizing, , pressing, anti-rust oil treatment and other processes.
