The elbow should be made by the manufacturer, and it must be preserved and the ordering period is long. The cold bend pipe can be bent with a ready-made straight pipe bender. One-time completion does not require secondary corrosion protection. The cold-bending pipe construction process has a petroleum standard, and the West-East Gas Pipeline has enterprise specifications. However, the elbows in the open areas can be bent, only thinking about the cost, the elbows need to be hot, the bends can be cold bends, of course, the elbows are expensive. Sometimes elbows must be used in narrow sections, such as stone section trenches. Due to the small radius of curvature of the elbow, it is usually 6D and the elbow is 40D.

Assume that the diameter of the elbow is the most common. The long-radius is the most common. The common chrome carbide wear-resistant elbow is also a long radius. The center of the high pressure or high velocity will adopt a long radius. If the solid delivery pipeline resistance is severe, the time is required. Use a larger radius elbow.

Short radii are generally used in low pressure fluids or in the center where the elbow is limited in the installation.

The elbow is the part that connects the pipe and is also the pipe that changes the direction of the pipe. The angle is 45 degrees, 90 degrees, and the like.

The way in which the elbow is connected to the pipe is: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, thread connection and socket connection.

D is the diameter of the elbow, and the long radius is the most commonly used. The common chrome carbide wear-resistant elbow is also a long radius. The center with high pressure or high flow rate will adopt a long radius, if the solid delivery pipe resistance request is severe. Use a larger radius elbow.

Short radii are generally used centrally in low pressure fluids or when the elbow is limited in the device.
