Some knowledge of seamless elbows

Seamless elbows are a common pipe connection used to change the direction of fluid flow and velocity in pipe systems. It has the advantages of simple connection, high reliability, low fluid resistance, etc., and is widely used in petroleum, chemical industry, electric power, metallurgy, shipbuilding and other fields. In the following knowledge extension, we will detail the types of seamless elbows, manufacturing processes, material selection, application scenarios, and precautions.

First, the type of seamless elbow

Seamless elbows can be divided into two types, long radius elbows and short radius elbows, according to their curvature radius and elbow Angle.

1. Long radius elbow: The curvature radius of long radius elbow is usually 1.5 times the diameter of the pipe, and the Angle of the elbow is generally 90 degrees. Its streamlined design can reduce the resistance of the fluid, allowing the fluid to flow more smoothly in the pipeline, suitable for high-speed fluid and high-pressure pipeline systems.

2. Short radius elbow: The curvature radius of the short radius elbow is generally 1 times the diameter of the pipe, and the Angle of the elbow is usually 90 degrees. It is more compact than long-radius elbows and is suitable for situations where space is limited, but due to its poor streamlined design, it is prone to fluid resistance, so it is not suitable for high-speed fluid and high-pressure piping systems.

Second, the manufacturing process of seamless elbow
