90 Degree Steel Pipe Elbow

It changes the pipe flow in 90 degree so that it also named as vertical elbow. It is one of the most commonly used elbow type in all pipe systems, and suits for steel construction and structural.

45 Degree Elbow

45 Degree elbow produces less friction compared to 90 degree elbow, but it withstand lower pressure. It is change the fluid direction in 45 degrees.

180 Degree Elbow

Also know as return elbow, it provide 180 degrees direction change. The application is limited to minimum deposition and low turbulence system because it usually results in low pressure.

Long Radius Elbow

Any degrees elbow is available in long radius, it means the radius of elbow is equal to 1.5 times of its diameter.

Short Radius Elbow

Short radius elbow is often used when space is not enough. Its radius is equal to its diameter.
