The bent pipe is bent by a complete set of bending molds, which are divided into two processes: cold simmering and hot pushing. No matter what kind of machinery and equipment, most of them use elbows, which are mainly used for oil, gas, liquid, etc., and occupy a very important position in aircraft and their engines.
Almost all cross-sections of aluminum, steel, stainless steel, copper and other metal profiles and pipes (spiral pipes, straight seam steel pipes, seamless pipes) can be bent. The bending quality of the elbow pipe is good, and the materials after spraying, electroplating, polishing, wire drawing, etc. can be bent directly without damaging the surface of the material.
Classification of elbows:
1. According to the material, it is divided into carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon, PPC, etc.
2. According to the production method, it can be divided into pushing, pressing, forging, casting, etc.
3. According to the manufacturing standard, it can be divided into national standard, electric standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.
4. According to its true radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, ie R=1.5D. The short radius elbow means that its true radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D (D is the straightness of the elbow, and R is the true radius of curvature).
5. There are about seventeen types according to the pressure level, including: Sch5, Sch10s, Sch10, STD, Sch60, Sch80, Sch100, Sch120, Sch140, Sch160, XXS. Among them, STD and XXS are the most commonly used.

Pipe bending machines are roughly divided into CNC pipe bending machines, hydraulic pipe bending machines, etc., which are used in pipeline laying and repairing in power construction, highway and railway construction, bridges, ships, etc.
