Product Introduction
Steel pipe elbow is a key component in the pipeline system to change the direction of fluid flow. It is used to connect two pipes with the same or different nominal diameter, and turn the pipes to specific directions such as 45 degrees, 90 degrees, and 180 degrees.
For industrial pipe elbow, the type of connection end is butt welding according to the standard. Butt welding can be described as butt welding, butt welding and groove end.
Product Details
1. Classification by direction
We know that elbows can be divided into different angles according to the fluid direction of the pipe, such as 45 ° elbow, 90 ° elbow and 180 ° elbow, which are the most common angles. For some special pipes, there are also 60 degrees and 120 degrees.
2. Classification by material
Carbon steel is also called mild steel or black steel. As per ASTM A234 WPB
Stainless steel is the abbreviation of stainless and acid-resistant steel. The steel that is resistant to air, steam, water and other weak corrosive media or has the property of stainless steel is called stainless steel. Common ones are 304 and 316L
3. What is the elbow radius
Bend radius refers to the radius of curvature. If the radius is the same as the pipe diameter, it is called short radius elbow, also called SR elbow, which is usually used for low pressure and low speed pipes.
If the radius is larger than the pipe diameter and R ≥ 1.5 diameter, we call it the long radius elbow or LR elbow, which is applicable to high pressure and high flow pipes.
If the radius is greater than 1.5D, it will be named as a bend, and the elbow fitting usually represents such as 2d elbow, 3d elbow, etc.
4. Shape type
The elbow is divided into equal-diameter elbow and reduced-diameter elbow
The equal-diameter elbow is an elbow with the same diameter at both ends, which is mainly composed of the elbow body. Its feature is that the pipe connecting the two necks is of the same specification. The equal-diameter elbow has a proper structure and unique concept, which can directly achieve one-time connection with the same diameter, thus in the medium transmission process.
The reducing elbow is also called the reducing elbow. It is a pipe fitting that connects two pipes with different diameters.
