What is the production process for steel bending pipe

First, what is steel bending pipe?

Steel bending pipe is made by bending using a set of bending dies. It is used in most types of machinery and equipment, mainly for transporting oil, gas, and liquids. It plays a particularly important role in aircraft and their engines.

Second, can steel bending pipe bend various profiles?

Almost all cross-sections of aluminum, steel, stainless steel, copper, and other metal profiles and steel pipes (spiral steel pipes, straight seam steel pipes, seamless steel pipes) can be bent. Steel bending pipe has good bending quality; materials that have undergone spraying, electroplating, polishing, or wire drawing can be bent directly without damaging the material surface.

Third, what materials are used for variable diameter steel bending pipe?

(1) Cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics, etc.

(2) Connection with steel pipes: direct welding (the most common method), flange welding, hot-melt connection, threaded connection, socket connection, etc.

(3) According to the manufacturing process: welded elbows, stamped elbows, cast elbows, etc. Steel bending pipes are a common type of connecting fitting used in pipe installation, for connecting pipes at bends.

(4) Other names: 90-degree bend, right-angle bend

(5) Purpose: Used for two steel pipes with the same or different nominal diameters to make the pipeline turn at a certain angle.

Fourth, what are the classifications of steel bending pipes?

1. Steel bending pipes are classified by material: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon-bonded asphalt, PPC, etc.

2. Steel bending pipes are classified by manufacturing method: push-formed, pressed, forged, cast, etc.

3. Steel bending pipes are classified by manufacturing standard: national standard, electrical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.

4. According to the true radius of curvature of steel bending pipes, they can be divided into long radius elbows and short radius elbows. A long radius elbow has a radius of curvature equal to 1.5 times the outer diameter of the steel pipe, i.e., R = 1.5D. A short radius elbow has a true radius of curvature equal to the outer diameter of the steel pipe, i.e., R = 1.0D (D is the elbow's diameter, R is the true radius of curvature).

5. If classified by pressure rating, there are approximately seventeen types, which are the same as the American steel pipe standards: Sch5, Sch10s, Sch10, STD, Sch60, Sch80s, Sch100, Sch120, Sch140, Sch160, and XXS. Among these, STD and XXS are the most commonly used.
